Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone, and welcome back. This is our special holiday rewind edition of the thinkenergy podcast, which has become a bit of a tradition around here. I'm your host, Trevor Freeman, and as we settle into the final days of the year, it feels like the perfect time to slow down and take a look back at some of the conversations that we feel really shaped 2025 at least, for the podcast and in our own minds. This year, we explored everything from grid modernization to decarbonizing buildings distributed energy resources (DERs) and some of the technologies that are really defining how Canadians live, work and stay connected. Today's episode is the first of a two-part holiday rewind series, each part highlighting five standout episodes that we feel really sparked ideas curiosity and great discussions throughout the year. So pull up a comfortable seat, pour yourself something seasonal and festive, and join me as we revisit some of the insights and innovations that we feel lit up 2025 to start with, we kicked off 2025 with a forward looking conversation on some of the trends that we thought might shape the year, and to be honest that many of them unfolded even more quickly than we expected. In our first episode of 2025 we looked at clean energy trends. We talked through how electrification and AI driven grid intelligence and new customer expectations were really going to change the landscape in real time for us, here's a moment that we captured just how quickly the industry is accelerating and why adaptability is so important to us. At the same time, utilities across the country will continue to invest in grid modernization. So as well as infrastructure expansion, not just modernization, we're also building and growing our grids to keep up with the pace of change, but we need to also be able to leverage more DERs on the grid, so more distributed energy resources, small scale solar generation, things like that. So we will continue to see utilities make steps in that direction. They will look to levels of government to support those initiatives, through programs and funding and regulatory change. So we will continue to see that change in grid modernization, but I know it's definitely a big topic for us here at hydro Ottawa. And finally, in this section, energy efficiency. Energy efficiency is not new. It's been around for quite a while. In fact, it was the primary focus, kind of before we shifted a little bit more towards thinking about carbon. But we cannot fully decarbonize, we cannot fully electrify without significant energy efficiency. We just won't be able to affordably build the infrastructure we need if we're not using energy in an efficient way. So that will continue to be a focus. And in fact, I mentioned the new incentive programs from the province of Ontario that is very much designed to support ongoing energy efficiency measures. So we will continue to see that as a focus in 2025 and our final area, area number five, is technology. So there is no year anymore. In fact, maybe there never was where technology doesn't continue to grow and expand and evolve in ways that we couldn't even imagine, and it does seem like the pace of change is picking up, but I think that's kind of normal. So we will see technology that supports or augments the energy transition continue to evolve in 2025 and the ways that technology influenced that really, you know, we have an idea on some of them, and it'll be interesting to look back in 12 months at what we know in December, 2025 that we didn't even know here today in January. So there you have it. That's going back 12 months. And my expectation of what 2025 might have in store in the new year, I'll be doing a similar deep dive on some of the trends that we've been seeing over the course of this year and what we might expect to continue into 2026 but that idea that the pace of change is accelerating certainly became one of the defining themes of the year, and I think is something that we can expect to stick with us for the foreseeable future. And I think you'll hear echoes of that in all the different episodes that we revisit today. Next up, a modern, reliable grid doesn't just happen. It's built through long term planning, thoughtful investments and a deep understanding of how our communities are growing and how their energy needs are changing. In an episode that we. Least back in June, we unpacked hydro Ottawa's 2026 to 2030 investment plan, and what that means for reliability and customer experience and preparing the system for tomorrow. In this next clip, I chat with Hydro Ottawa's Guillaume Paradis to really get into why it's so critical that we get our investment in the next five years, right for our grid, so that that's a nice segue into his next question, which is, of course, there's a cost for this, and this is why it is an investment plan we're out there outlining. These are our targets. This is what we want to do, but there's a cost to that, and so if we don't do this, if we said, look, we just can't put that extra investment into these areas, what are the implications on the grid, on our service? And let's look at kind of like, quality of service, reliability, safety, etc, if we don't make these investments that we are identifying right now. Guillaume Paradis 06:03 Yeah, so it's pretty direct, right? What we've done for the in preparation for our rate application, in preparation for to develop our plans for 26 to 2030 is we've considered all the needs. We've looked at how old the assets are, how quickly they're deteriorating, how many might require replacement over the next five years, what would be an appropriate rate of replacement to ensure that we don't let risk build up in our system, we don't cause reliability issues. We've looked at how we make sure that we can provide service to our customers, that we can connect them in a timely manner, that we can do all those things in a fashion that is safe and ensures the safety of the public, our customers. And so a lot of thought goes into what is required over the next five years. And then on top of those factors and considerations, we also look at what impact will this have financially on our customers, because we're mindful that our service does affect, you know, our customers live, yes, in a positive manner when our service is reliable and power is available, but also financially. From a cost standpoint, we add to other pressures that everyone experiences in their lives, and so we want to be very judicious in setting the size of our programs the level of investments in managing those various factors, right? So we have a multifaceted responsibility, and we weigh all those factors in in our setting the plans for the future. So doing so looking five years out, as you can probably imagine, you know, if we didn't constrain the plans, if we just did everything our planning engineers would like to do, we would have spent probably another 50% more than what is in the current plan. So looking at old assets, looking at the service levels we want to deliver, we could have spent a significantly larger amount of money if it was purely based on we'll call them planning, you know, drivers. But as I said, we are mindful that we're responsible for the quality of our service on behalf of all our customers. And we took a very deliberate, extensive approach to adjusting the program size to match the various considerations and ultimately manage the impact on our customers from a financial standpoint. And so we landed where we are after some measure of restraint, some measure of adjustments down to the plans that would otherwise have been put in place. So thinking about what the outcomes would be if we didn't take the actions we're proposing. You know, it's pretty direct, if you think about it, and we've covered most of them, but it ranges from, you know, difficulties in connecting and delivering power to new customers in a timely manner so that can have impacts with respect to economic development and growth of our community so fairly direct, and frankly, you know, it's our obligation to connect, so we would do everything we can to provide power, but it might just be more difficult take more time on the reliability front again, what happens when you don't replace old assets is the failure risks continue to build in your system. So an 80 year old wood pole doesn't get any younger and. Doesn't get any stronger if you wait five, six more years. And so as I said, we do a risk assessment before we choose to invest, and our risk assessments tell us that we need to take action on those type of assets. And you know, take action in a timely manner. If we don't, what is likely to happen is that in a storm scenario, those polls that are deteriorated are more likely to fail, even in normal conditions, it's likely that we would see more failures that could lead to reliability issues, and so just a direct impact on the quality of our service for our customers, with respect to other outcomes, like enabling customers and supporting them in integrating more embedded energy resources, that might just become more difficult, as I said earlier, when we're don't have good real time awareness, we have to err on the side of caution and be more conservative in our management of the system, and that might mean restrictions on where and how we can integrate renewable energy resources. And then ultimately, you know, the paramount consideration for us is always safety, and that's an area where we would just have to be even more vigilant if we couldn't reinvest so old assets are inherently more likely to create failure risks and failures can lead to undesirable outcomes from a safety standpoint. So we would have to and already do, but be very vigilant in monitoring those assets, looking at them, looking at what we can do from a maintenance standpoint to ensure that they don't fail in a manner that would be problematic. So we would be an R always very active in looking at those riskier assets, those older assets, to make sure they don't cause problems. But reducing investment levels from what is being proposed now, reducing them further relative to, as I said, the planning levels we would have liked to put forward would have real consequences. And of course, we would do everything we can to manage those consequences and ensure that, you know, we continue to deliver the best service we can, but that would become more difficult than it is today. Trevor Freeman 12:29 So that forward focus, that planning for the city that Ottawa is becoming and our energy needs of the future really reflects that shifting mindset that we're seeing across the whole sector. And I think we saw that throughout 2025 and certainly are going to keep seeing that throughout 2026 for our next clip, one of our most popular conversations of the year, not surprisingly, was with Andrea Nuesser from Capgemini, Canada. Andrea and I dug deep into what it means to modernize the grid, how technology, data, cybersecurity and customer expectations are all coming together and pushing utilities into a new era of grid management and grid design. This was a really great, wide-ranging conversation, but there was one moment that really stood out for its clarity and simplicity, and it highlighted this idea that modernizing the grid isn't just about technology alone. It's primarily about people. Yeah, well, let's do that right now. Actually, it's exactly where I wanted to go. Next is you and I have chatted before and talked about how there is this shift in how utilities are seeing customers, and there's a traditional mindset of how utilities looked at their customers, which has been different from you know, take your average retail customer, or retail relationship between an organization and a customer, utilities are shifting more. So let's dive into that. Tell me a little bit more about what that shift is, and how you see utilities moving in terms of how they engage with customers. Andrea Nuesser 14:00 Yeah, so when I started working with utilities, the term rate payer was a very prominent term. So utilities would refer to their customers as rate payers, or in terms of account numbers, really and what mattered was really just how much electricity do these accounts or these rate payers consume, and there was very little other consideration around that. So I think there's a real shift happening right now where utilities are trying to understand who is this, who is this family, who are these individuals behind these account numbers? Because if I understand and if I become interested as a utility in who is actually consuming electricity, I can have a very different relationship with them. I can reach them with the right messaging, because it matters a lot to me. And if somebody talks to me and understands that. Let's say I'm a growing family living in a more urban area versus a retired couple out in the booth somewhere. So I think demonstrating that understanding really opens up opportunities for much deeper relatio…

    Blue energy: powering the future with Marine Renewables Canada Nov 24, 2025
    Show notes

    Waves, river currents, and tidal turbines could help power Canada's clean energy future. Trevor speaks with Elisa Obermann, Executive Director at Marine Renewables Canada, about the promise of marine energy and how countries like Canada are pursuing its potential. They explore how emerging 'blue energy' technologies complement solar and wind, support coastal and Indigenous communities, and move us toward a more sustainable, diverse net-zero grid.

Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone, and welcome back. I have a really great conversation for you today, but before I get to that, I think it's worth a minute or two of time to revisit some first principles people approach the energy conversation from all different backgrounds and angles, and I think it's good to make sure that we're all on the same page when it comes to some foundational knowledge before we dive into our topic today, the thing that I want to quickly review is electricity generation. Now don't worry, we're not going to get into an advanced physics level of knowledge on this, but I just want to quickly refresh everyone on the basics. And by the same token, to all of you advanced physics folks out there that are listening, please forgive me if I'm slightly off on a detail or two, as long as I don't mess up the core foundational information. So for the most part, the electricity that we use is primarily generated by spinning a coil of wire around a magnet, or inversely, spinning a magnet inside a coil of wire that causes electrons to move, and that flow of electrons is electricity. For the most part, that combination of coiled wire and magnets and a spinning motion is what makes most of our electricity. There is one major exception to this, which is solar power that doesn't involve spinning anything. But other than that, our major electricity sources utilize that spinning motion, and I'm not including hydrogen fuel cells here as a major source of electricity. So let's keep going with this spinning idea. Then the next question is, how do we make things spin? One very common method is heat. Let's say you burn something, coal or natural gas, for example, which creates heat. You then use that heat to boil water, which makes steam, which you can push at high pressure against turbine blades to make them spin. It's as simple as that. The problem is, burning things creates harmful emissions, which are causing climate change. You can also generate heat with non emitting sources, and a major one, especially here in Ontario, is nuclear power, splitting atoms in a controlled environment, a nuclear reaction generates heat and then the process is the same as previously described. So as complex as a nuclear reactor is its main purpose when it comes to electricity generation, is simply making heat so we can boil water and create steam, et cetera, other than heat. The other way to make things spin is to utilize naturally occurring kinetic energy. So that means something that's already happening out there that carries a lot of force that can push a turbine blade. This would include wind energy, so using the force of the wind to turn large wind turbines and hydro electricity, which uses water being pulled downhill by gravity, so a flowing river or a large dam to turn that turbine the same end results that spinning motion, but no need to create heat to get there. We're almost done with the science lesson, so just bear with me for another few seconds as we think about reducing our carbon emissions, finding ways to generate electricity that don't require burning fossil fuels is really important. Solar definitely has a role to play, but we also need more emissions free ways to spin things. I mentioned some of the more traditional ones, like solar and wind energy, but today's conversation is about some lesser known, emerging methods, which are covered by the term marine renewable energy generation. Phew, it was a long walk to get there, but we finally got here. All of that is to tee up my conversation today with Elisa Obermann, the Executive Director of Marine Renewables Canada. Marine Renewables Canada is the National Association for tidal wave and river current energy in addition to offshore wind. But it's those first three generation strategies that I am particularly interested in as non mainstream ways to spin things. These technologies are known as blue energy, but are often overshadowed by the more common renewable energies that we talked about, solar and wind generation. So I'm really excited to chat with Elisa to shed some light on them. Today. Elisa has served as the executive director of marine renewables Canada since 2015 she's a founding member of both the Electricity Alliance Canada and the Canadian Council on Renewable Electricity. She has also worked for several other organizations that focus on clean technology, tidal energy and the broader renewable energy sector, including Sustainable Development Technology Canada, the Fundy Ocean Research Center for Energy. Which you'll hear us talk about today as force and Nova scotia's Department of Energy. Elisa Obermann, welcome to the show. Elisa Obermann 05:07 Hi. Thank you very much for having me. Trevor Freeman 05:09 So, let's start off kind of with the basics. Elisa, why don't you tell us a little bit about your background and how you got into this pretty unique space in the energy sector that we're going to dive into a little bit more. Elisa Obermann 05:22 Sure. So I decided after doing my undergrad, so I'm going kind of way back here, all the way back. Yeah, exactly. I did a degree, a bachelor's degree in English, but I really wanted to get involved in something that would help me do more for the environment, play a role in the future. So I decided to go back to school to do a public policy degree. And the first internship I had was with Nova Scotia Department of Energy, and it was actually on the oil and gas side of things, but my thinking was, well, this will get me eventually to where I want to go and working more in renewables. And that's essentially exactly what happened. And so I started working more and more there on renewable energy. Then started working on the province's marine renewable energy strategy. So it really kind of got me into this kind of path of, you know, working on climate change and renewable energy. And the other thing I will also say is that I grew up in Maine and really close to the ocean, and so after university, I moved to Toronto for a while, and I thought to myself, like, I really just want to do something that takes me back to the ocean. So this really combines both kind of goals I had for myself, in terms of working to protect and help the environment, and then also staying close to the ocean. Trevor Freeman 06:35 Yeah. I mean, that makes a ton of sense. It's interesting. I talked to a lot of people, obviously, and often the question of career path comes up, and it's funny to see the things that we're passionate about in those early days, no one could guess how that comes to fruition later on in our careers. And you know, I've got some similar stories of wanting to save the world when I was in university and having no idea how the different paths that that would take me on. So great to hear your story. Thanks for sharing that. Tell us now a little bit about your organization, marine renewable Canada, and you know, kind of its vision for how marine renewables will fit into the energy sector. Elisa Obermann 07:10 Yeah. So marine renewables Canada is a National Association. We're headquartered in Halifax, but we do work across the country, and actually, our beginnings were in British Columbia, really starting around like wave energy, small scale projects. One of our founding members at the time was BC Hydro. We now have over 200 members, and that's really grown just in the past couple years, because our focus is on wave, tidal, river current energy, but also offshore wind. And so there's been a lot of excitement, especially on the East Coast, around offshore wind, but today I'll probably focus mostly on kind of those water resources and how we're working to advance those. Our mandate is really to champion the sector, help with advocacy, engagement, education, and also expand market opportunities. So obviously we do a lot of work around enabling policies that help open up that market, both here, but also globally. But ultimately, what we'd like to see is that marine renewables is playing a role in getting Canada to net zero and right now. I mean, it's a more emerging technology, if you look at wave, tidal and river, but there's a lot of potential for it to play a big role. Trevor Freeman 08:20 Yeah, so great. And that's a great segue into kind of the next thing I want to talk about on this show. We often talk about, let's call them the more traditional or conventional or well known energy sources, so our kind of traditional fossil fuel combustion, our other renewable sources, solar and wind, and even offshore wind, I think people have a sense of what that is. I mean, wind energy is the same on land as off land. It's just in a different location. But tell us about the types of marine energy that you're talking about. You just referenced some of them here, you know, take us back to basics. What are we talking about when we talk about marine energy? Elisa Obermann 08:56 Yeah, absolutely. So I would categorize it as four main kinds, but I also will mention that there are some that our association doesn't cover. And I will touch on those, sure, primarily. So we focus on tidal energy. And when I say tidal I don't mean barrages or dams, which were kind of a more prevalent technology, you know, decades ago. What I'm talking about is what we call tidal stream and so essentially, if you think of, you know, what wind turbines look like, it's essentially a wind turbine, but in the water, so it can be developed or deployed incrementally, which is a lot different than what you think of when you think of a dam that has, you know, very long lasting effects. The idea behind title is that you can install it incrementally if there's concerns and with any kind of impacts to the environment, or concerns with, you know, the technology failing, or anything like that, you are able to remove it, or, you know, have maintenance on it fairly quickly. Wave Energy is another one that we focus on. It's the technology is not as far along as tidal in terms of, you know, getting to a commercial state. And there are many different. Different types of concepts, still for Wave technologies, but essentially, they can be placed near shore or further offshore. One of the things that's been, I think, kind of cool to think about is there's discussions around and some prototype type projects around using wave energy to power, for example, oil and gas platforms and doing that kind of, you know, pairing to help decarbonize that sector's energy use, river current. So I will say a lot of people think marine like that doesn't, you know, make sense rivers, you know, not by the ocean. And the reason we look at it and categorize it as a Marine renewable energy is that the technology is very similar to title, and so it's essentially the same technology that's used, except that it is unidirectional. So when you think of the flow of river, it's going one way, whereas tides, the technology would be used as a bi directional because the tides are going in and out. So but otherwise very, very similar. And then we actually also cover offshore wind, which is, of all of those, you know, a more mature marine renewable technology. And as I said, I think probably today I'll talk mostly about some of the earlier stage technologies. Our association doesn't cover a few others, and I just feel like they're worth mentioning, just because they're kind of cool. Also, floating solar is one that is gaining, you know, I think some more popularity, and also people are looking more what you know, how much of an impact it could have, ocean current technology, which would be kind of further offshore, and ocean thermal. And you can imagine, Ocean Thermal hasn't really been talked about a lot in Canada, because you have colder waters. Like, the technology just isn't right, the right fit. Trevor Freeman 11:35 Got you okay? So I want to, I've got a whole whack of questions I want to understand, make sure I'm understanding the technology correctly. So let's start with Tidal. For Tidal, obviously, just a quick refresher back to, let's say grade 10 science for our listeners. Tides kind of come in and come out. The water moves up and moves down. You're utilizing that flow of water, that movement of water, which happens twice a day. Is that, right? Twice a day, every 12 hours? Elisa Obermann 12:02 Yep, Trevor Freeman 12:02 Good, yeah, just making sure I remember my grades and science most part. And you're using that movement of water to turn turbines that are underwater. Describe those for us. Is that, like you kind of related it to wind energy? Is it like a big wind turbine underwater? Does it look the same? Is it similar to that? Elisa Obermann 12:20 Yeah, I mean, there's still a few different concepts, but essentially, yeah, that's how you could picture in your mind. I will say some are bottom mounted. So as an example, like it might have a gravity base and be anchored to the well, not even anchored. It could just be the weight of it is holding it to the sea floor. Some of the newer tidal technologies are floating. They're kind of like, on a pontoon type device, and they will have kind of the, you know, the turbines connected to that. But essentially, they're, you know, either way, whether it's floating or seabed mounted, it would be capturing the kinetic energy of the tides Trevor Freeman 12:54 Gotcha, okay. And then for the run of ri…

    thinkenergy shorts: hydropowering Ontario's north with renewable energy Nov 10, 2025
    Show notes

    Hydropower is one of the oldest sources of renewable energy, powering Canada's first electric lights in 1881 and providing clean energy to six out of ten homes and businesses today. Ontario's north leads its next chapter. Trevor sums up how new hydro projects with First Nations transform remote communities, reduce diesel reliance, and support reconciliation. With billions invested in refurbishing plants and expanding the grid, it's a story of clean energy, collaboration, and Canada's sustainable future.

    Trevor Freeman 00:07

    Welcome to a think energy short hosted by me, Trevor Freeman. This is a bite sized episode designed to be a quick summary of a specific topic or idea related to the world of energy. This is meant to round out our collective understanding of the energy sector, and will complement our normal guest interview episodes. Thanks for joining and happy listening. Hi everyone, and welcome back to think energy. I'm your host, Trevor Freeman, and today we're shifting our lens to the north. Across North America, we are seeing a resurgence of hydro power, and that includes here in Ontario, where I'm located, this province is looking to this long standing generation method to power Canada's growing and energy starved northern communities first. Let's take a quick look back at history. Canada's first electric lights were actually powered by hydro power. Back in 1881 a small hydro electricity plant in Sherbrooke, Quebec lit up the night and sparked a clean energy story that's still unfolding today, from those earliest River power lights to today, where we see more than 200 hydro stations generating over 60% of Canada's electricity and about 90% of our renewable power. Hydro power remains backbone of our clean energy system and powers six out of 10 homes and businesses. It's reliable, it's cost effective, and unlike solar wind, which can be intermittent, water, provides a steady stream of power pretty much 24/7 some plants have even been operating for more than a century. But according to water power Canada, because we've been relying on this source for so long, there is actually a lot of untapped potential that can be realized by refurbishing and modernizing our older facilities, not to mention developing new ones. We could significantly expand clean capacity, which would help us move closer to our net zero goals. As I've said before on the show, we need every tool in the toolbox, and expanding hydro power is one of those tools. So let's have a look at the North American resurgence of hydropower across the continent, there is a renewed focus on this source as a stable, long term solution to rising energy demand. Even the tech sector is taking notice. In July 2025 Google announced a $3 billion deal to secure hydro power from two US facilities in Pennsylvania through Brookfield asset management. It is the largest corporate clean energy agreement of its kind, which is a signal of how essential reliable renewable power has become. In this digital age, we need something to power these giant AI data centers, and these corporations are looking for something that's reliable and clean. The hydropower sites will be upgraded and relicensed under the agreement, and Google also intends to expand the deal into other regions of the US, Midwest and mid Atlantic, where it's investing $25 billion in new data centers. This deal signals a shift in corporate energy procurement, from simply buying renewable energy credits to offset their emissions to directly investing in specific, large scale, long duration infrastructure deals to power businesses. Of course, this definitely raises questions about the implications for how the grid and energy markets may evolve as demand in the tech and business sector continues to change and grow. That's something we'll explore at a different time. While Google's deal is driven by data and growth. Ontario's story is being shaped by geography, reconciliation and regional development. So let's have a look to the north. Like we said we would when electricity grids were first built, many northern and remote communities were left out because connecting them wasn't seen as practical or affordable. I talked about this with Gemma Pinchon from Quest Canada about a year ago on this show. Have a listen if you haven't already. With small populations spread across vast distances, it was considered too costly to run transmission lines that far north. So while the rest of the country was plugged into their provincial grids, many of these communities were left to rely on local diesel generation, a decision that might have made economic sense at the time, but definitely isn't equitable and not great for the environment. Thankfully, we're seeing some movement in this area. New investments and partnerships are changing how energy is produced and shared, and Ontario is turning once again, to our water power routes, but this time, it's doing it differently. This year, the Ontario government announced several new partnerships with First Nations that are changing the way clean energy projects take shape, emphasizing shared ownership, community leadership and lasting local benefits. New hydro developments in the north are being co created with First Nations who've lived alongside these rivers for generations. So let's have a look at some specifics. In July, the province announced plans for two new large scale hydro electric stations in northern Ontario, the Nine Mile rapids project on the Abitibi River and the Grand Rapids project on the Mattagami. Together, these could generate up to 430 megawatts of clean electricity that's enough to power. Nearly half a million homes. This is the province first large scale expansion of hydro electricity facilities in decades. What makes these projects truly historic is who's at the table. The stations will be co developed with the Taykwa Tagamu Nation and the Moose Cree First Nation, marking a shift towards shared ownership and long term community benefit. It's a model of collaboration that intertwines energy expansion with economic reconciliation, and this is just part of a larger effort. Ontario has also committed $4.7 billion to refurbish and expand existing hydro electric facilities across the province, from Northern Ontario to Niagara Cornwall and all the way out east. Together, these upgrades could add another 5000 megawatts of reliable clean power. It's a move that fits squarely within Ontario's long term plan to meet rising demand in the north with reliable low carbon power. The IESO, our system operator, predicts northern Ontario's demand for electricity will increase by 81% by 2050, higher than the provincial average. Of course, generating electricity is only half the story, as we've talked about before. It needs to reach the people in the industries that need it to make that happen, Ontario is working with transmission partners to build 1000s of kilometers of new power lines across the north. A prime example is Watay Power, the largest indigenous led grid connection project in Ontario's history. It's 1800 kilometers of transmission lines will connect more than 18,000 people across 16 remote First Nation communities to the provincial grid for the first time, ending decades of dependence on diesel. These grid expansions are also laying the groundwork for future economic development, especially in the mineral rich Ring of Fire region. The province recently signed a 39 and a half million dollar community partnership agreement with the Wabequie First Nation to support infrastructure early works and an all season road that will unlock access to critical minerals essential for EV batteries and clean technologies. Hopefully, this is a sign that we're seeing a real shift in how Canada views its north, not just as a remote region, but as a cornerstone of the country's future. The federal government is linking energy development, mining and national security in a way that we haven't seen in decades. There's renewed investment in hydro and transmission projects, plans to tap into critical minerals for the clean economy and a growing military infrastructure to reinforce sovereignty in the Arctic. It's all part of a bigger effort to power the north, protect it and ensure the communities who live there share the benefits of its growth. So what does all this mean? Ontario's investments aren't just about electricity. They're about sovereignty, sustainability and self determination. They represent a vision for Canada's north, where the local power generation, indigenous leadership and economic opportunity grow together. Still, there are important questions ahead that we'll all be watching. How will the province balance clean growth with ecological protection? How can partnerships ensure that the benefits of these projects are lasting and equitable for both the province and First Nations leading this work on their own traditional lands? In the end, the real energy transformation isn't just about megawatts. It's also about connection and making sure that we're smart about how we grow and expand our grid and our communities. Thanks for checking in. We'll chat next time. Thanks for tuning in to another episode of the think =energy podcast.

Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone, and welcome back. Today's episode brings us back to a few elements of my own personal history. Now you'll have to bear with me for a minute or two while I dive into my past in order to properly set up today's conversation, I grew up in southwestern Ontario, in and just outside the border town of Windsor, Ontario. Now for those of you not familiar with this area, Windsor and its surroundings are the most southern part of Canada. It might surprise you to know that Windsor is at the same latitude as Northern California and Rome, Italy. You can imagine that after growing up in Windsor and then living in various places around the globe, when I finally settled down here in Ottawa, adjusting to the more stereotypical Canadian winters of this northern capital, took a little bit of getting used to Windsor is so far south when you cross the border to its neighboring American city, Detroit, Michigan, you actually travel north. Have a look at a map if this seems to defy logic, but I promise you, it's true. This is the area that I grew up in. It's also where I went to school and got my engineering degree. More on that in a minute. Now, if you've ever driven down to the southwestern end of the 401 going past London and Chatham, you will notice two things. First, it is flat, very flat. You will not see a meaningful Hill anywhere in sight. I often joke with people that I used to toboggan when we did get any meaningful snow off of highway overpasses, because that was the only hill we could find. I was only partly joking, and I have indeed tobogganed off of said overpasses in my young and foolish days. But that is a story for another time. That brings us to the second thing you'll see, which is wind turbines. A lot of wind turbines. They are seemingly everywhere, stretching as far as you can see, southwestern Ontario is a hotbed of wind energy generation. Finally, a hint at why I'm going on about this part of the province on an energy podcast. But before we get into it, there's one other thing to touch on, and that is the fact that this area is also home to a large number of greenhouses growing produce year-round, as well as manufacturing. Windsor and its surrounding area is the automotive capital of Canada, with a number of plants from major car companies, as well as a supporting ecosystem of parts manufacturers. Incidentally, that's where I started my career, working as an environmental engineer for one of the automakers, and many members of my family have also worked or still work in that industry. The reason I bring up greenhouses in the auto industry is because they have some very high energy demand profiles, and that is how we get for me going on nostalgically about the area I grew up in, to our conversation today, I recently caught up with one of my engineering professors, Dr Rupp Carriveau, about the work that he and his colleagues have been doing that ties all of this together. And I thought it would be great to have him on the show to talk about that. Dr. Carriveau is the director of the Environmental Energy Institute and co-director of the Turbulence and Energy Lab and the CO lead of AGUwin at the University of Windsor. Back in the day, he was my fluid dynamics professor. But today, he balances his teaching duties with research into energy systems futures and advanced agricultural systems. He is a founder of the offshore energy and storage society, a recipient of the University Scholar Award, and has been named to Canada's clean 50 for his contributions to clean capitalism. Dr Rupp Carriveau, welcome to the show. Dr Rupp Carriveau 03:59 Trevor, great to be here. Thanks. Trevor Freeman 04:01 Yeah. So, Rupp, the last time we chatted, well, so you and I chatted a couple weeks ago, but before that, the last time that you and I interacted, I was in third year university. You were my fluid dynamics Prof. So, in addition to your professorial duties, you're now the director of the environmental Energy Institute at the University of Windsor. So, there's two questions around that. First off, how did you end up going from my fluid dynamics prof a number of years ago, probably close to 20 years ago now, to running this institute? And tell us a little bit about what the Institute does. Dr Rupp Carriveau 04:40 Sure. Though. So, thanks. Yeah, and very memorable Trevor, because I, you know, I remember you well. And, yeah, that was, that was a very nice class that we had. I remember, well, I remember your colleagues too. Trevor Freeman 04:54 If there's one thing I do, well, it's, it's be memorable, and you can take that however you want. Dr Rupp Carriveau 04:58 That is, that is. Something to be said for that. Yeah, thanks for that question. So I should point out that in addition to EEI, I am a co-director in the Turbulence and Energy Lab, which is really where all of the EEI initiatives have started from, that's a lab that I co supervise with Dr David Ting in mechanical engineering and the nuts and bolts, the very serious engineering side of things, comes out of the Turbulence and Energy Lab. EEI kind of came about to handle topics that were, frankly speaking, less interesting to Dr Ting. So, things that push more, a little bit more into policy wider systems looks at things as opposed to, you know, pure thermodynamics and energy efficiency type pursuits, which underpin a lot of the EEI policy pieces, but are sort of beyond the scope of what turbulence and energy lab does. So those two things, and then more recently, actually, I'm co lead on, AGUwin, which is like a center of excellence, emerging Center of Excellence at the University of Windsor. So, Agriculture U Windsor is a group of about 40 professors that do work in agriculture in some shape or form. And we've, we've, we've taken to organizing that movement in seeking sort of group funding proposals, developing curriculum and organized sort of platforms to help industry in agriculture. And it's, it's really taking off, which I'm really excited about my extremely hard-working colleagues and CO lead, Isabel Barrett-Ng, she in particular, has been really driving a lot of really cool initiatives ahead and all the people that work with us. So, yeah, lots, lots happening at the University since I saw you last. But you know, time has a way of helping with that, people find ways to find efficiencies and get to do and build on, build on, hopefully incremental progress. Trevor Freeman 07:08 Yeah, very cool. And you're teasing a few of the areas our conversation is going to go today, that sort of intersection between agriculture and obviously, this is an energy podcast, and so how does agriculture and the way we're moving in with agriculture impacts energy and vice versa. So, we're definitely going to get to that in a minute, I think, for our listeners that are not familiar with Southern Ontario, and I haven't talked about Southern Ontario on the podcast a lot, but people that know me know I will gladly talk about what goes on in the very southern part of our country. It's where I grew up. Help us paint a picture of what Southern Ontario is like. So, in the context of energy, what makes this area of Ontario unique? Dr Rupp Carriveau 07:50 Well, it's that's a really good question, and I'm glad you phrased it that way, because I think it gets taken for granted. And also, folks, folks don't know energy isn't in the headlines every day, and if it is, it's not a headline that everybody pays attention to. But the southwestern Ontario region, if you take the 401 west of London, you'll start to see a high concentration of wind. So, there's a significant wind corridor in the region, and that's because it's very flat, so the whole area used to be a lake bed, and so we have very fertile agricultural lands as a result of that. And we also have very few obstacles to fetch, which is a huge aspect of how wind carries over the lakes, and is, you know, not, not obstructed. And so it's like you have offshore resources onshore, which is completely ideal. Also, we have, as it may be, we have massive natural gas resources in the area, in sort of the subterranean space of Devonian reefs for natural gas storage. We have natural gas generation facilities down around the Windsor area that help with provincial peaking and there is some solar in the region, because it is the Leamington Kingsville area is referred to as the sun parlor of Ontario. And as a result, we have a lot of under glass agriculture there, which benefits, obviously, directly from solar resources. And then we have solar photovoltaic that takes advantage of that sun as well. So there's, there's a lot happening here energy wise. Trevor Freeman 09:38 Yeah, and there's a lot on the demand side of things as well. So, you mentioned the greenhouses, which are an up and coming, you know, source of demand draws on our grid. There's also a big manufacturing base. Talk a little bit about the manufacturing base in the area. Yeah, yeah. And that's that gets into my next question is talking about some of the specific, unique energy needs of greenhouses. I think on the manufacturing side, you know, you mentioned the auto industry and the parts industry that supports it, you're seeing more. There's a battery plant being built now I think that, I think people have a sense of that, but greenhouses are this thing that I think a lot of folks don't think about. So, you talked about the magnitude of the load, the lighting side of things. What else is this like, a 24/7 load? Is this sector growing like? Tell us a little bit about, you know where things are going with greenhouses? Dr Rupp Carriveau 09:53 Yeah, thanks. So, yeah, I was, I was thinking about generation and, yeah, demand is. Significant we have. You know, Windsor has laid claim to Canada's automotive capital, and while I'm biased, I'd like to think it still is. And so we have significant manufacturing around the automotive industry, either automotive OEMs or tier one parts makers that have significant draws. We have Stellantis. Every minivan comes out of this area has come out of this area. The electric Dodge Charger comes out of this area. But there are engine plants for Ford, but they're also now, you know, sort of next generation transport technologies. You've talking about battery manufacturing. So, there's an enormous LG consortium with Stellantis here that's doing battery manufacturing. And so, these are huge loads that that add to existing and growing loads in the greenhouse space, which, again, I'll just mention it now, is something that isn't well understood. And we did a, we did a study for the province a couple years, three, four years ago. Now, I think grid Innovation Fund project that looked at sort of really getting into granular detailing of the loads that come with a lit greenhouse. A lot of people don't appreciate that a lit greenhouse, when switched on, depending on the lighting technology, depending on how it's used, can be like a 50-megawatt load, which is a significant load. And just imagine that's one so they can come on quickly, and they are non-trivial, significant loads. And so, this is something that we looked at trying to develop distributed energy resource sort of solutions for, because, simply speaking, you can't put up a new transmission line overnight, and we don't want to economically constrain the growth of the sector. Sure, yeah. I mean, it's, it's not a simple thing to characterize, because what you can take away from this is that these greenhouse developers are business dynamos, and frankly speaking, many of them do very well, because they're very good at what they do, and with the resources they have, they can largely do what they want. And if, if the infrastructure isn't there, they will build it so. So, you'll have folks that are operating off the grid, essentially not off the gas grid, of course, but they're using gas for cogeneration purposes, to produce heat for their crops, but also the electricity for their lights. So that is one aspect of it that further complicates how to figure out what these loads on the grid will be. But for the most part, of course, the grid provides quite clean and quite affordable electricity in the province, and you know where they can they want to be able to connect to the grid. Now, lights are designed to extend the growing day and extend the growing season as well. So, in terms of when they're switched on and how they're switched on, that is highly variable, and that is also something that is, I would say, in development, folks are looking at different ways to use intermittent lighting to be conscious of when peaking happens. It is dispatchable in a way, in that some growers are able to turn their lights off to avoid, you know, peaking charges. But again, there's a lot to manage. And, and it's, it's very complicated, both on the grid side and, and for the greenhouse grower. Trevor Freeman 14:38 Yeah, so you mentioned natural gas for cogen for heating as well. So, as we look to decarbonize all different aspects of the sector, we talk often on the show of what are the specific areas where decarbonization might be challenging. Is, is greenhouses one of those areas? And, and what are the options available for heating these spaces? Like, is it realistic to think that there's an electric solution here, or what? What's happening in that sector related to decarbonization? Dr Rupp Carriveau 15:10 Again, you've hit on a real sort of hot button issue for the for the sector, the trouble with natural gas is that it's spectacular. Oh, it's storable. It's dispatchable. It's a triple threat for greenhouses in the best way possible, because you can make your heat,…

    Transcript:

    Welcome to a think energy short hosted by me, Trevor Freeman. This is a bite sized episode designed to be a quick summary of a specific topic or idea related to the world of energy. This is meant to round out our collective understanding of the energy sector, and will complement our normal guest interview episodes. Thanks for joining and happy listening. Hi everyone, and welcome back. Today on think energy, I'm going to talk about distributed energy resources, or DERs. Now, if you've been listening to the show for a long time or even a short time, you will have heard us talk about DERs many times before, and for good reason. DERs are an important and growing part of our energy lives. About a year ago, I did an episode diving into what DERs are, and I encourage you to go back and listen to that one. But today I thought I do a quick refresh and talk about some of the most common ways that DERs are used. So, let's dive right in. First the refresh. DERs or distributed energy resources, are simply pieces of equipment that can generate or store power, generally on the smaller scale size of things, and spread throughout the grid. So, we're not talking about large scale, centralized generation plants here, but that small to medium scale, kind of think rooftop solar or batteries that are sized for home or facility use. And generally, when we're talking about DERs, we're focused on renewable technology like solar panels or batteries, and in some cases, you know, smaller wind turbines. For the most part on this show, that's what we're focused on. However, there are sort of non-renewable DERs as well, and we'll actually touch on that a little bit later. So, let's dive into what some of the reasons are why someone would want a der there's a couple of different reasons. The first is for backup during an outage. So, using solar panels, especially if paired with a battery, can give you some backup if there's an outage from the grid, whether that's a storm or an accident or something like that, that backup power can be focused on your key devices or systems or appliances, or if your storage is big enough, or your system is big enough, it may be used to power your whole home for a period of Time. Of course, if you're using one of those nonrenewable sources that I mentioned, like a fossil fuel power generator, for example, then your backup supply can last longer, really, as long as you've got fuel, but it's not clean, so you will be producing carbon emissions. One emerging technology that we'll likely see more of in the future is using an electric vehicle for this purpose. So, while there's only a few different models that allow this right now, the Ford f1 50 is one of them, and there are some safety and regulatory considerations before you go ahead and do this, we can expect to see more of this in the future as the technology advances and it becomes a bit more widespread. Another reason for DERs is financial. Installing a der can actually help you save money every month, whether that's just by reducing what you consume from the grid or by pushing back unused generation to the grid for credits. And I'll touch on this a little bit more shortly. Finally, if we're talking about those renewable DERs, they produce clean energy. So that's carbon, free emissions, free energy. And if you are concerned about your carbon footprint, you're trying to decarbonize and reduce the amount of emissions that you cause. DERs, renewable DERs are a great way to do that. You can lower your carbon footprint by reducing how much you draw from the electricity grid and any carbon emissions that are associated with that. Okay, so let's go back to the financial use case for a minute and talk about the different ways that that's possible. I'll be speaking about the Ontario context here. So, if you're listening from outside of Ontario, you'll have to do a little bit of your own research to figure out what options exist where you live. One option to set up your der for financial reasons is net metering, which I kind of alluded to earlier. Net metering is a setup for renewable generation sources only that allows you to use as much of your generation as you can to power your home when you're using it, and then push back whatever you don't use to the grid. Whatever you push back to the grid, will give you a credit on your bill that you can use to offset the electricity charge portion of your bill. Another option would be load displacement. With this arrangement, you can generate electricity exclusively for your own use, so you will reduce the amount that you pull from the grid, and that will save you money, but you don't push anything back to the grid, and therefore you don't earn any credits. And finally, there are standalone generation setups. This arrangement involves pushing all of your generation back to the grid for some agreed upon compensation. While there used to be programs for small scale standalone generation so you might be familiar and on. Ontario with the fit or the MicroFit programs that existed about 10 years ago. These programs are closed today, and generally only large generators have a standalone arrangement. Now, like any technology, DERs are not free to install. In fact, they can be quite pricey in some cases, but because they provide benefit to the grid. There are incentive programs out there to help reduce the upfront costs. Here in Ontario, the ISOs save on energy programs provide an incentive to any customer type, from residential all the way up to large commercial to install rooftop solar, and homeowners can access additional funding to install the battery along with their solar. If you're interested in doing this, or you want to learn a little bit more, you can reach out to your LDC, visit our website. If you're in hydro Ottawa's territory, or visit save on energy.ca. In the near future, you will also likely see more utilities wanting to partner with der owners. I talked about this a little bit in my last episode with Andrea Nusser About grid modernization here at hydro Ottawa, we are working on a technology project that will be launched next year that will enable der owners to leverage their devices for an incentive to help manage the grid in targeted areas. It's pretty exciting stuff, and it's really the next wave of distributed energy resources on our grid and how we're going to interact with them. It's pretty exciting. So, there you have it. That's a quick summary of the different ways that DERs are used.

    Trevor Freeman 00:07

    Welcome to a thinkenergy short, hosted by me, Trevor Freeman. This is a bite sized episode designed to be a quick summary of a specific topic or idea related to the world of energy. This is meant to round out our collective understanding of the energy sector, and will complement our normal guest interview episodes. Thanks for joining and happy listening. Hi everyone, and welcome back to thinkenergy. I hope you all had a great summer at equal parts restful and exciting. Certainly, we had a great summer here. It was good to take a bit of a step back and think about all the exciting topics that we have to talk to you about coming up over the course of the next season of the think energy podcast. And it's nice to be back here behind the microphone. I'm recording this just at the tail end of summer, the kind of end of August, and looking forward to getting into lots of good content this year. Today, we're going to start off our season with a look at the impact of extreme weather on our grid, as our grid is already under pressure from growing electricity demand. So it's a bit of a look at what utilities are doing in the face of that pressure. So this will be a think energy short, and we'll bring you our guest episode the next time around. So let's dive right in then. What does extreme weather mean for Canada's electricity infrastructure, and should we be worried about its ability to handle that extreme weather? This is kind of top of mind right now. We're at the tail end of summer. It's been a pretty hot and dry summer, at least where I am. Incidentally, I'm about to head into Algonquin Park for a backcountry camping trip, and there's a fire bed on and that's not unheard of in Algonquin Park and in many parts of the country, but this late in the season, it's pretty rare. I think this might actually be the first time that we've had a fire ban so late in the season that I can remember that I've been camping on and I go pretty frequently. So that'll be a little bit unique. And so yeah, a hot, dry summer is certainly one of those things we think of when we think about the changing weather patterns. But this is also top of mind because Rukshar Ali, who's a journalist with CTV, has been exploring, you know, the weak points in Canada's electricity grids, and has been writing about what impact extreme weather might have on those grids. So at a very high level, Canada's power grids as they are built today and in the past, as they have been built. So at a high level, Canada's power grids, as we've been building them for the last 100 years or so, need improvements in order to be able to withstand the frequent extreme weather and growing demand for electricity that we're having. That's not anything new, we talk about that often, how we need to invest in our grid for both reliability as well as expansion and the growing electrification of our society. Climate change is here, extreme weather is here, and those things are adding strain to our grid at the same time that demand is increasing and the grid is is redundant in many aspects. If we lose one component, then we can continue on and serve parts of our customer base from other sections. But extreme weather events are likely to knock out several aspects of the grid at once, and we need to improve in order to be able to withstand that. To give you a sense of the magnitude of the issue, the North American Electric Liability Corporation predicts that within the next decade, half of North America will be at risk for a significant blackout. So let's talk a little bit about why extreme weather as we know as the as the globe warms up from climate change, the frequency and magnitude of weather events increases, so we'll see more extreme weather events, and those extreme weather events will be more extreme, to reuse that word, and we're already seeing this. So last year, for example, severe weather caused 1000 outages in Nova Scotia, between 2013 and 2023 if we look across the entire country, there were around 10 extreme weather events that caused nearly 20 million customers to lose power across Canada. And eight of those 10 extreme weather events occurred in the five year period between 2018 and 2023 so that the frequency of these very significant, very extreme weather events, is definitely growing up. This is all happening at the same time that the country's electricity demand is also increasing and placing pressure on our infrastructure. So we know that usage is going to grow with electrification. We've talked about that a lot here and here in Ontario, the Independent Electricity System Operator, is projecting that consumption will increase by 75% by the year 2050, which is a significant jump up. And so as demand is increasing, we're also seeing that pressure on the grid from that and extreme weather kind of exacerbates that problem too. So extreme heat waves cause people to use their air conditioners more frequently and for longer, and that puts greater demand on the grid as well. So in July of 2023 you might recall this extreme kind of heat period in British Columbia out on the West Coast, and there's the heat dome, and that period saw the province use about 8% more electricity on average, than the previous kind of six year July average. So there is a significant increase from that one single heat event. So what do we do about this? How do we act in the face of increased extreme weather and electrification. Well, first off, we definitely need to update our infrastructure. And utility companies across the country and indeed across North America know this and have already started to do this here in hydro Ottawa's territory, for example, as I've talked about before, hydro Ottawa has a five year investment plan covering the 2026 to 2030 period, which is the largest investment plan in our company's history, and it carries a significant amount of investment in grid reliability, grid modernization, improving and expanding our infrastructure for just these challenges, so for the extreme weather and increased electricity demand across Our grid, if you zoom out a little bit and other parts of the country, the East Coast, for example, Nova Scotia Power recently finished a pole replacement project that saw a significant number of poles being replaced, and they're now moving into a Smart Grid Initiative, which is similar to grid modernization that I've talked about Here on the show in the past, which also addresses utilization of the grid, as well as ability to react during an outage on a bigger scale across the entire country, the federal government has promised to look at an east, west electricity grid, which would help connect more Canadians to more affordable and reliable power. And obviously, new construction would be focused on being able to withstand extreme weather as well as bring on more electricity demand as part of electrification. We've talked here in the past on the show, and the CTV journalist Ali points out that the current grid system makes it a lot easier for provinces to transfer electricity to the United States. It's kind of that north south flow of electricity is a lot easier than an East West flow of electricity. So trading between provinces today is difficult, and that's why there's a push for a national grid, an East West grid, that would make it a lot easier for Canadians to share electricity amongst each other. This would also have the benefit of helping connect more rural and remote communities. So I draw your attention back to a podcast episode I did with quest Canada, where we talked about some of those more remote communities and how a lot of them are not connected to a reliable grid. So there's a lot of work that can be done to really shore up how we connect across the country to the different areas, especially with a major east west grid. And of course, this is supported during this kind of, you know, a little bit tumultuous political climate that we have as we're reevaluating trading relationships with the United States, with other countries, it's important that we really focus on, how do we make sure things flow very well within our own borders? Beyond just the transmission and the grid upgrades that we need to do, we also need to look at diversifying our supply of electricity. So here in Canada, we use a lot of hydro generation, but extreme weather that causes droughts put that at risk. And so low water levels can impact electrical production, and we need to be prepared to have alternative sources as well. We still need to focus on making sure those sources are renewable. So really looking at expanding wind, solar, nuclear energy in some cases, as well as building out other hydro electric generation resources, is really important to have a good diversified mix. And on top of all that, we also need to continue looking at, how can we lower our energy consumption, especially during those peak times, especially when the grid is under stress at certain times of the day or from certain weather events. And we've seen that this can work. So in January 2024 the Alberta electric system operator, or IESO, issued an alert. It was a cold weather alert asking customers to reduce their electricity use during an extremely cold period in that province. And. And shortly after that, there was a 200 megawatt drop in electricity demand, which really helped the province avoid a series of rolling outages and avoid some real challenges on the grid. So it does work when customers are asked to alter their behavior in, you know, hopefully, small and subtle ways to manage grid peaks, and that's a really huge tool that we have. And we've talked before on the show about the role of managing peak times on the grid and being able to shift some of that usage to other times to avoid over stressing the assets that we have. That's going to be a really important strategy as we face increasing demand and extreme weather outages to make sure we're not over stressing the grid. So to sum that all up, extreme weather is going to impact our grid, and utilities do need to be aware of that and plan for how to build a grid that is more resilient and more reliable in the face of that increasing extreme weather. The good news is that utility companies know this and are already moving in that direction, and hydro Ottawa is a good example of that, of really focusing on building out reliability on its grid with some of the investment plans that we have put forward, and that extends all the way up to the federal level as well, where our federal leadership is looking at, how do we plan a EAST, WEST grid, really build out that provincial grid, and while we do that, a continued focus on energy efficiency and reducing electricity demand during peak times, and the various tools that we have to do that. So yes, extreme weather is coming, but there's a plan of how to deal with that. So thanks for tuning in today. It's really great to be back here behind the microphone and chatting with you all. Our next episode is another look at grid modernization, but this time through a customer lens, and really, what does grid modernization mean for customers? So stay tuned and join us in two weeks for our next episode. Thanks for tuning in to another episode of the think energy podcast.

    Summer Rewind: Digging into Hydro Ottawa's historically large investment plan Aug 25, 2025
    Show notes

    Summer rewind: Hydro Ottawa recently unveiled its largest investment plan ever, with a five-year focus on modernizing and strengthening the grid. The way we're consuming energy is changing, and this investment plan focuses on four key areas that highlight why Hydro Ottawa is taking action, and how they plan on doing it. Hydro Ottawa's Chief Operating Officer, Guillaume Paradis, joins thinkenergy to dive a little deeper into those focus areas, and why they matter, with host Trevor Freeman.

Well, summer is here, and the think energy team is stepping back a bit to recharge and plan out some content for the next season. We hope all of you get some much needed downtime as well, but we aren't planning on leaving you hanging over the next few months, we will be re releasing some of our favorite episodes from the past year that we think really highlight innovation, sustainability and community. These episodes highlight the changing nature of how we use and manage energy, and the investments needed to expand, modernize and strengthen our grid in response to that. All of this driven by people and our changing needs and relationship to energy as we move forward into a cleaner, more electrified future, the energy transition, as we talk about many times on this show. Thanks so much for listening, and we'll be back with all new content in September. Until then, happy listening. Trevor Freeman 00:55 Welcome to think energy, a podcast that dives into the fast changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydroottawa.com. Trevor Freeman 01:19 hi everyone, and welcome back. A few episodes back I talked about some of the important work that happens at the distribution level to maintain and expand our grid, and I tried to connect the dots between that work and the broader societal energy transition that is happening at all levels. How the work we do at the distribution level is really important and tied to some of those larger projects that may get a little bit more news and attention that energy transition, which, as you're hopefully aware by now, is ongoing right now. It's not something of the future. It's happening today. That energy transition is multifaceted, but from an electricity and electrification perspective, the distribution utility, ie the Hydro Ottawa, of whatever jurisdiction you're in, is at the very leading edge of many of the changes we need to see within our electricity system to support that transition. So today, I'd like to go a little bit further with that topic and focus on Hydro Ottawa's next five year investment plan, which covers the 2026 to 2030 period. This will be the largest investment plan in our history as a company. And I wanted to dig into what we have identified as key focus areas for investment in the coming five years, with more than 100 years of operating a large, complex distribution network, Hydro Ottawa is embarking on a pretty significant journey to modernize and strengthen our grid for the challenges and opportunities ahead of us. We have filed our 2026, to 2030, Electricity Distribution rate application, as it's called, with the Ontario Energy Board, and this is a standard practice for all local distribution companies in Ontario. That's what we have to do. As a reminder for our listeners, the Ontario Energy Board, or OEB, as we often call it, is our independent regulator. Their mission in this process is to strike a balance between ensuring the financial health and operational needs of utilities like Hydro Ottawa, while also safeguarding the affordability and reliability of the service for the customer. So they want to make sure that we're spending enough to tackle the right projects on the grid, to make sure it stays operational while not spending too much. They meticulously scrutinize every detail of these applications to ensure that the proposed rates are just and reasonable, and that all investments are prudent and really in the public interest. So we have gotten a number of questions about the plan and specifically around where is the money going to go? What are you going to actually spend these dollars that you're requesting on? And why are these investments necessary? What benefits are they actually going to bring to our community? And often we get the question of, does this mean less outages or shorter outages? So I want to dig into that. I want to talk a little bit about what we've got planned and what the impact will be, and what the impact would be if we don't do those things, and to help me walk through that energy roadmap, that plan that we've put together. I've got Guillaume Paradis joining me today. Guillaume is the Chief Operating Officer of generation and distribution here at Hydro Ottawa, and he's going to join me, and we're going to talk through this. Guillaume and his teams are responsible for the planning, design, operation, construction and maintenance of our electrical power distribution system, and in his role, he leads the teams that are directly accountable for ensuring the safe, efficient and reliable delivery of electricity to our customers. Today, I'm going to ask Guillaume, really, to walk us through the details of. Our investment plan, how it was shaped, how we came up with these specific areas, and what benefits are going to be realized by our community and the broader energy landscape. Guillaume, Paradis, welcome to the show. Pleasure to be here. Trevor, okay, so, Guillaume, this is Hydro Ottawa's largest investment plan ever, and I'd like you to start by talking us through the primary drivers behind what our five year investment plan is. Guillaume Paradis 05:29 Yeah, so as you've heard, as you've seen, we're in a historical, or historically, you know, unique point in the evolution of our industry. Electricity underpins most of our societal aspirations with respect to creating, you know, a more sustainable future, creating the future we want to leave for the next generations. And our distribution system underpins a lot of those aspirations in simple ways and in more complex ways. So, you know, a simple way is that essentially, for, you know, the well being of our society, for our customers, the residents of Ottawa, and really any area, to live the lives they're hoping to live, to, you know, enjoy the benefits of modern life. Electricity is a critical underpinning in any way you can imagine and you know, think about so. Our service has always been very important. It's just become even more critical as a foundational block for you know, the lives that we're hoping to live and we're living today in our modern society. So that, combined with other aspirations related to where we can reducing our carbon footprint and integrating more renewable energy resources within our footprint, it creates a situation where there's a significant need for us to invest, continue to invest and reinvest in our infrastructure to deliver those outcomes for customers. Trevor Freeman 07:16 Yeah, I think, I mean, we talk a lot about the energy transition on the show, and if, if you think about, you know, let's say our previous rate application five years ago, the energy transition was a thing we knew about it, but it was like a thing of tomorrow where, hey, that's going to come soon. The difference now, I assume, and maybe you can speak to this, is we're seeing that. We're seeing the change now. Guillaume Paradis 07:40 Yeha, you're exactly correct, like we're in it now. So we've been talking about it for some time, both from a like a general societal aspiration standpoint, but also from a technological standpoint. For a very long time, we talked about electric vehicles having an impact and becoming more commonplace. We talked about leveraging automation to deliver our services. We talked about two way power flows. So we've been building toward this moment, and now we're essentially in it, if you will, and we're seeing all those things, the confluence of all those longer term trends, sort of manifest themselves in real demand for our system, in real changes in our customers want to use energy, and we're in the middle of that, and we're, you know, to enable those things happening in our community here in Ottawa. Trevor Freeman 08:36 Yeah. So it's like the business as usual, a lot of the same things, and we're going to talk about some of this. About some of the specifics, but a lot of the same thing, things we would normally do just a lot more of at the same time, as like also pivoting a little bit to meet some of these new needs, like charging transportation and like heating our spaces, more of electricity, like some of these new needs that didn't exist are not to the same extent. So it's like more of the same plus other new stuff, and we're gonna talk about that in a minute. Guillaume Paradis 09:11 Yeah. So, you know, we always would say that the future of the energy sector was very exciting, and things were coming and like, change was upon us, and now, essentially, we're, we're living it, right? So you have to carry on with the responsibilities that you always had, and meanwhile, figure out how to deliver those new outcomes, those new services that previously weren't required or expected, right? Trevor Freeman 09:39 So let's, let's kind of get into some of the details here. So there are four key capital investment categories in this plan, so growth and electrification, aging, infrastructure, grid modernization and grid resilience. So we're going to dive into the specifics of these in a minute, but we're. To start off with why these four? How did we land on these four as the main categories? Guillaume Paradis 10:07 Yeah, so there's, there's various ways you can categorize investments. There's a lot of drivers that will lead us to invest in an area or replace some infrastructure somewhere in our system, these categories capture quite well. What is at the core of various investments. So for one specific investment, there will be multiple drivers, but these ones sort of in an elegant way, I would say, capture. You know why investments are occurring, what the primary driver is for those investments, and they help translate that for folks who are not involved day to day in planning the electricity system, that's our responsibility. What we're trying to communicate is why we're taking action where we're taking action. So those categories, in my mind, capture that really well. They also tie our investments to broad trends that people should be aware of, and they're a way to make sure that we have, you know, a clear baseline for a conversation as we proceed with those plans. Trevor Freeman 11:18 Yeah, one thing I find, and you know, in my role, I talk to customers a lot, and I find these are fairly easy to explain, or at least, I hope they are, if you're listening and you disagree, let us know. But people can kind of get their heads around why the utility needs to do each of these four things, and some, in some ways, they align with other sectors as well. So I think, and I hope, as we carry on our conversation here, it'll be easy to sort of build out the picture of what we're doing in each of those four areas. So why don't we? Let's dive right in then and look at the specifics. And starting with growth and electrification, what are the specific investments that are planned to support the growing energy needs of our community, you know. And we've already started talking about electric vehicles, other electrified aspects of our lives, like, what? What falls into this category? Guillaume Paradis 12:11 Yeah, so with respect to growth and electrification, um, there's a few underlying trends that drive the investment requirements. So as you've suggested, as you mentioned, you know, there's an evolution of how our customers use energy at home, day to day. EVS being obviously a primary example that everyone will be very aware of. Just, you know, driving around town, frankly, the difference in how regularly you'll see electric vehicles in our community relative to even five years ago is is pretty dramatic, and that is having a long term, you know, impact over time, likewise for technologies like heat pumps at home, and just generally, the growth of our community. So those elements just drive a longer-term trend of more demand being present in our community, within our system. And in addition to that, one big change that we've seen over the last few years is more large scale demand request coming into our service territory, typically, that will be large customers wanting to do something different with energy. So it could go. It could be driven by a few different kinds of corporate aspirations. What we're seeing a lot of are instances where large corporations decide, or institutions decide, to do away with more carbon intensive energy sources, so they will look to us and electricity to replace what previously would have been another fuel source that maybe is less green. So we're seeing that affecting choices some of those type of customers are making, and then at the same time, we're seeing just large requests related to a different type of energy demand. So companies wanting to, for example, bring back their R and D efforts to a data center that they operate and they control, so that they have more control over cybersecurity elements, and then, likewise, with where their data flows to and how it's being managed. So we're seeing large requests at a rate that we didn't previously, and that those requests are significant enough that they require us to make very major investments, like new substations, like building a. New feeders again at a pace that far outpaces what we've seen historically. So the underlying trend of more small demand creating an impact at the aggregate level, combined with those larger requests, that's creating a significant need for us to invest in responding to that growth in the electrification drivers within our system. Trevor Freeman 15:29 Yeah, so this is in response to what we're seeing our customers do. And that's it's something that has come up before in conversation here. Of you know, we we respond to what we see our customers doing and what our customers are asking us. They're asking for more power. We have to respond to provide that more power. So this, this kind of area of investment, is really just building out the grid and all of the assets and infrastructure that are that make up the grid to be able to meet the needs of our customers, which are growing faster than they were previous…

Artificial intelligence, or AI, is a term that you're likely seeing and hearing everywhere today, and with good reason, the effectiveness and efficiency of today's AI, along with the ever increasing applications and use cases mean that in just the past few years, AI went from being a little bit fringe, maybe a little bit theoretical to very real and likely touching everyone's day to day lives in ways that we don't even notice, and we're just at the beginning of what looks to be a wave of many different ways that AI will shape and influence our society and our lives in the years to come. And the world of energy is no different. AI has the potential to change how we manage energy at all levels, from our individual devices and homes and businesses all the way up to our grids at the local, provincial and even national and international levels. At the same time, AI is also a massive consumer of energy, and the proliferation of AI data centers is putting pressure on utilities for more and more power at an unprecedented pace. But before we dive into all that, I also think it will be helpful to define what AI is. After all, the term isn't new. Like me, many of our listeners may have grown up hearing about Skynet from Terminator, or how from 2001 A Space Odyssey, but those malignant, almost sentient versions of AI aren't really what we're talking about here today. And to help shed some light on both what AI is as well as what it can do and how it might influence the world of energy, my guest today is Greg Lindsay, to put it in technical jargon, Greg's bio is super neat, so I do want to take time to run through it properly. Greg is a non resident Senior Fellow of MIT's future urban collectives lab Arizona State University's threat casting lab and the Atlantic Council's Scowcroft center for strategy and security. Most recently, he was a 2022-2023 urban tech Fellow at Cornell Tech's Jacobs Institute, where he explored the implications of AI and augmented reality at an urban scale. Previously, he was an urbanist in resident, which is a pretty cool title, at BMW minis urban tech accelerator, urban X, as well as the director of Applied Research at Montreal's new cities and Founding Director of Strategy at its mobility focused offshoot, co motion. He's advised such firms as Intel, Samsung, Audi, Hyundai, IKEA and Starbucks, along with numerous government entities such as 10 Downing Street, us, Department of Energy and NATO. And finally, and maybe coolest of all, Greg is also a two time Jeopardy champion and the only human to go undefeated against IBM's Watson. So on that note, Greg Lindsey, welcome to the show. Greg Lindsay 04:14 Great to be here. Thanks for having me. Trevor, Trevor Freeman 04:16 So Greg, we're here to talk about AI and the impacts that AI is going to have on energy, but AI is a bit of one of those buzzwords that we hear out there in a number of different spheres today. So let's start by setting the stage of what exactly we're talking about. So what do we mean when we say AI or artificial intelligence? Speaker 1 04:37 Well, I'd say the first thing to keep in mind is that it is neither artificial nor intelligence. It's actually composites of many human hands making it. And of course, it's not truly intelligent either. I think there's at least two definitions for the layman's purposes. One is statistical machine learning. You know that is the previous generation of AI, we could say, doing deep, deep statistical analysis, looking for patterns fitting to. Patterns doing prediction. There's a great book, actually, by some ut professors at monk called prediction machines, which that was a great way of thinking about machine learning and sense of being able to do large scale prediction at scale. And that's how I imagine hydro, Ottawa and others are using this to model out network efficiencies and predictive maintenance and all these great uses. And then the newer, trendier version, of course, is large language models, your quads, your chat gpts, your others, which are based on transformer models, which is a whole series of work that many Canadians worked on, including Geoffrey Hinton and others. And this is what has produced the seemingly magical abilities to produce text and images on demand and large scale analysis. And that is the real power hungry beast that we think of as AI today. Trevor Freeman 05:42 Right! So different types of AI. I just want to pick those apart a little bit. When you say machine learning, it's kind of being able to repetitively look at something or a set of data over and over and over again. And because it's a computer, it can do it, you know, 1000s or millions of times a second, and learn what, learn how to make decisions based on that. Is that fair to say? Greg Lindsay 06:06 That's fair to say. And the thing about that is, is like you can train it on an output that you already know, large language models are just vomiting up large parts of pattern recognition, which, again, can feel like magic because of our own human brains doing it. But yeah, machine learning, you can, you know, you can train it to achieve outcomes. You can overfit the models where it like it's trained too much in the past, but, yeah, it's a large scale probabilistic prediction of things, which makes it so powerful for certain uses. Trevor Freeman 06:26 Yeah, one of the neatest explanations or examples I've seen is, you know, you've got these language models where it seems like this AI, whether it's chat, DBT or whatever, is writing really well, like, you know, it's improving our writing. It's making things sound better. And it seems like it's got a brain behind it, but really, what it's doing is it's going out there saying, What have millions or billions of other people written like this? And how can I take the best things of that? And it can just do that really quickly, and it's learned that that model, so that's super helpful to understand what we're talking about here. So obviously, in your work, you look at the impact of AI on a number of different aspects of our world, our society. What we're talking about here today is particularly the impact of AI when it comes to energy. And I'd like to kind of bucketize our conversation a little bit today, and the first area I want to look at is, what will ai do when it comes to energy for the average Canadian? Let's say so in my home, in my business, how I move around? So I'll start with that. It's kind of a high level conversation. Let's start talking about the different ways that AI will impact you know that our average listener here? Speaker 1 07:41 Um, yeah, I mean, we can get into a discussion about what it means for the average Canadian, and then also, of course, what it means for Canada in the world as well, because I just got back from South by Southwest in Austin, and, you know, for the second, third year in row, AI was on everyone's lips. But really it's the energy. Is the is the bottleneck. It's the forcing factor. Everyone talked about it, the fact that all the data centers we can get into that are going to be built in the direction of energy. So, so, yeah, energy holds the key to the puzzle there. But, um, you know, from the average gain standpoint, I mean, it's a question of, like, how will these tools actually play out, you know, inside of the companies that are using this, right? And that was a whole other discussion too. It's like, okay, we've been playing around with these tools for two, three years now, what do they actually use to deliver value of your large language model? So I've been saying this for 10 years. If you look at the older stuff you could start with, like smart thermostats, even look at the potential savings of this, of basically using machine learning to optimize, you know, grid optimize patterns of usage, understanding, you know, the ebbs and flows of the grid, and being able to, you know, basically send instructions back and forth. So you know there's stats. You know that, basically you know that you know you could save 10 to 25% of electricity bills. You know, based on this, you could reduce your heating bills by 10 to 15% again, it's basically using this at very large scales of the scale of hydro Ottawa, bigger, to understand this sort of pattern usage. But even then, like understanding like how weather forecasts change, and pulling that data back in to basically make fine tuning adjustments to the thermostats and things like that. So that's one stands out. And then, you know, we can think about longer term. I mean, yeah, lots have been lots has been done on imagining, like electric mobility, of course, huge in Canada, and what that's done to sort of change the overall energy mix virtual power plants. This is something that I've studied, and we've been writing about at Fast Company. At Fast Company beyond for 20 years, imagining not just, you know, the ability to basically, you know, feed renewable electricity back into the grid from people's solar or from whatever sources they have there, but the ability of utilities to basically go in and fine tune, to have that sort of demand shaping as well. And then I think the most interesting stuff, at least in demos, and also blockchain, which has had many theoretical uses, and I've got to see a real one. But one of the best theoretical ones was being able to create neighborhood scale utilities. Basically my cul de sac could have one, and we could trade clean electrons off of our solar panels through our batteries and home scale batteries, using Blockchain to basically balance this out. Yeah, so there's lots of potential, but yeah, it comes back to the notion of people want cheaper utility bills. I did this piece 10 years ago for the Atlantic Council on this we looked at a multi country survey, and the only reason anybody wanted a smart home, which they just were completely skeptical about, was to get those cheaper utility bills. So people pay for that. Trevor Freeman 10:19 I think it's an important thing to remember, obviously, especially for like the nerds like me, who part of my driver is, I like that cool new tech. I like that thing that I can play with and see my data. But for most people, no matter what we're talking about here, when it comes to that next technology, the goal is make my life a little bit easier, give me more time or whatever, and make things cheaper. And I think especially in the energy space, people aren't putting solar panels on their roof because it looks great. And, yeah, maybe people do think it looks great, but they're putting it up there because they want cheaper electricity. And it's going to be the same when it comes to batteries. You know, there's that add on of resiliency and reliability, but at the end of the day, yeah, I want my bill to be cheaper. And what I'm hearing from you is some of the things we've already seen, like smart thermostats get better as AI gets better. Is that fair to say? Greg Lindsay 11:12 Well, yeah, on the machine learning side, that you know, you get ever larger data points. This is why data is the coin of the realm. This is why there's a race to collect data on everything. Is why every business model is data collection and everything. Because, yes, not only can they get better, but of course, you know, you compile enough and eventually start finding statistical inferences you never meant to look for. And this is why I've been involved. Just as a side note, for example, of cities that have tried to implement their own data collection of electric scooters and eventually electric vehicles so they could understand these kinds of patterns, it's really the key to anything. And so it's that efficiency throughput which raises some really interesting philosophical questions, particularly about AI like, this is the whole discussion on deep seek. Like, if you make the models more efficient, do you have a Jevons paradox, which is the paradox of, like, the more energy you save through efficiency, the more you consume because you've made it cheaper. So what does this mean that you know that Canadian energy consumption is likely to go up the cleaner and cheaper the electrons get. It's one of those bedeviling sort of functions. Trevor Freeman 12:06 Yeah interesting. That's definitely an interesting way of looking at it. And you referenced this earlier, and I will talk about this. But at the macro level, the amount of energy needed for these, you know, AI data centers in order to do all this stuff is, you know, we're seeing that explode. Greg Lindsay 12:22 Yeah, I don't know that. Canadian statistics my fingertips, but I brought this up at Fast Company, like, you know, the IEA, I think International Energy Agency, you know, reported a 4.3% growth in the g…

Well, summer is here, and the think energy team is stepping back a bit to recharge and plan out some content for the next season. We hope all of you get some much needed downtime as well, but we aren't planning on leaving you hanging over the next few months, we will be re releasing some of our favorite episodes from the past year that we think really highlight innovation, sustainability and community. These episodes highlight the changing nature of how we use and manage energy, and the investments needed to expand, modernize and strengthen our grid in response to that. All of this driven by people and our changing needs and relationship to energy as we move forward into a cleaner, more electrified future, the energy transition, as we talk about many times on this show. Thanks so much for listening, and we'll be back with all new content in September. Until then, happy listening. Trevor Freeman 00:55 Welcome to think energy, a podcast that dives into the fast changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, Hi everyone. Welcome back one of the overarching aspects of the energy transition that we have talked about several times on this show is the need to change our relationship with energy, to rethink the standard way of doing things when it comes to heating and cooling and transportation, et cetera. This change is being driven by our need to decarbonize and by the ongoing evolution and improvement of technology, more things are becoming available to us as technology improves. On the decarbonization front, we know that electrification, which is switching from fossil fuel combustions to electricity for things like space and water heating, vehicles, et cetera, is one of the most effective strategies. But in order to switch out all the end uses to an electric option, so swapping out furnaces and boilers for heat pumps or electric boilers, switching all gas cars to EVs, et cetera, in order to do that in a way that is affordable and efficient and can be supported by our electricity grid. We need to think about multi strategy approaches, so we can't just continue to have this one way power grid where every home, every business, every warehouse or office tower satisfies all of its energy needs all the time directly from the grid with no adaptability. That isn't the best approach. It's not going to be affordable or efficient. We're not going to be able to do it fast enough. The multi strategy approach takes into account things like distributed energy resources, so solar and storage, et cetera, which we've talked about many times on this show, but it also includes approaches like district energy. So district energy is rethinking how energy flows between adjacent buildings, looking for opportunities to capture excess energy or heat from one source and use that to support another, and that is the focus of today's conversation to help us dive into this topic, I'm really happy to welcome Scott demark to the show. Scott has been a champion of sustainability, clean energy solutions and energy efficiency in the Ottawa real estate and development industry for over 20 years now, he has overseen many high performance development projects, and was one of the driving forces behind the Zibi development in downtown Ottawa, and most applicable for today's conversation the renewable district energy system that provides heating and cooling to the Zibi site. Scott is the president and CEO of the Zibi community utility, as well as a partner at Theia partners. Scott the Mark, welcome to the show. Thanks. Nice to see you. Trevor, so Scott, why don't we start with definitions are always a good place to start. So when we talk about a district energy system, give us a high level overview of what exactly that means. Scott Demark 04:15 Sure a district energy system is, is simply the connection or interconnection of thermal energy sources, thermal energy sinks. And so really, in practical terms, it means, instead of buildings having their own furnace and cooling system, buildings connect to a hydronic loop. A hydronic loop is just pipes filled with water, and then the heat or the cooling is made somewhere else, and that heat or lack of heat cooling is in a pipe. They push the pipe to the building, and then the pipe extracts the heat, or rejects the heat to that loop. And so it's simply an interconnection of. Uh, as it forces in sinks for federal energy. Trevor Freeman 05:03 And I guess one of the important concepts here is that buildings often create heat, not just through a furnace or not just through the things that are meant to create heat, but, you know, server racks, computer server racks, generate a lot of heat, and that heat has to go somewhere. So oftentimes we're cooling buildings to remove heat that's being created in those buildings, and then other buildings nearby need to be heated in order to make that space comfortable. Scott Demark 05:31 Is that fair to say? Yeah, absolutely. Trevor, so, a an office building in the city of Ottawa, big old government office building, you'll see a pretty big plume on the roof in the wintertime. That's not just kind of the flue gas from a boiler, but rather it is actually chillers are running inside to make cooling, and they're just selling that heat to the atmosphere, even on the coldest day of the year. So it's people, you know, people are thermal load. Computers are thermal load, and so is solar gain. You know, January is pretty dark period for us, meaning low angle sun, but by this time in a year, you know, at the end of February, there's a lot of heat in that sun. So a glass building absorbs a lot of sun an office building will lead cooling on the sunny side of that building a lot of the time, even in the dead of Trevor Freeman 06:18 winter, yeah. So a district system, then, is taking advantage of the fact that heat exists, and we don't necessarily need to either burn fossil fuels, or, even if it's a, you know, a clean system, we don't have to expend energy to create heat, or create as much heat if we could move that heat around from where it's kind of naturally occurring to where we need Scott Demark 06:41 it. That's right at the very core of a district energy system. You're going to move heat from a place that it's not wanted to a place that it is wanted. And so in our example of the office building, you know, on the February day with the sun shining in and the computers all running, that building's getting rid of heat. But right next door, say, there's a 20 story condo. Well, that 20 story condo needs heating and it also needs domestic hot water. So year round, domestic hot water represents 30, 35% of the heating load of any residential building, so at all times. So a district energy system allows you to take that heat away from the office building and give it to the residential building, instead of making the heat and and dissipating that heat to the atmosphere in the office building. So, yeah, it's, it's really a way to move, you know, from sources to sinks. That's, that's what a district energy system does well. Trevor Freeman 07:37 So we've kind of touched on this a little bit, but let's dive right into, you know, we talk a lot on the show about the energy transition this, this push to one, move away from fossil fuel combustion to meet our energy needs, and two, shifting from a kind of static, centralized energy system like we have right now, big generators, large transmission lines, et cetera, to more of a two way flow, distributed energy system. What is the role of district energy systems within that transition? How do they help us get closer to that sort of reality that we talk about? Scott Demark 08:15 I think the biggest way that they help is economies of scale. Okay, so by that, I'll explain that. Imagine there's a lot of technology that's been around a long time that is very scalable to the building level, but most of them are fossil fire. Okay, so the the cheapest way to heat a building in Ottawa is to put a gas fired boiler in. That's the cheapest capital cost, first cost, and it's also the cheapest operating cost, is to put a gas boiler in that industry is well established. There's lots of trades who could do it. There's lots of producers who make the boilers. When you start to try and think about the energy transition and think about what you may do to be different, to be lower carbon, or to be zero carbon, those industries are, are just starting right? Those industries don't exist. They don't have the same depth, and so they don't have the same cost structure, and oftentimes they don't scale well down to the building. And therefore a district energy system aggregates a bunch of load, and so you can provide a thermal energy so at scale that becomes affordable. And that is, you know, a very good example of that would be where, you know, you might want to go and and recover heat from some process. And we'll talk about Zibi as the example. But if you want to go recover heat from some process and bring it in, it doesn't make sense to run a pipeline to a source to heat one building. You can't make financial sense of it, but if you're heating 20 buildings, that pipeline, all of a sudden makes sense to take waste heat from somewhere, to move it somewhere else. The other advantage is that truly, district energy systems are agnostic to their inputs and outputs for heat. So once you. Establish that hydronic loop, that interconnection of water pipes between buildings. What the source and what the source is doesn't matter. So you may have, at one point, built a district energy system, and Markham District Energy System is a great example of this. Markham district energy system was built on the concept of using a co generation facility. So they burned natural gas to make electricity. They sold electricity to the grid, and they captured all the waste heat from that generation, and they fed it into a district energy system. Well here we are, 20 plus years later, and they're going to replace that system, that fossil fired system Augment, not fully replaced, but mostly replace that system with a sewer coupled energy recovery and drive those heat recovery chillers to a sewer system. So they're putting a very green solution in place of a former fossil solution. They don't to rip up the pipes. They don't have to change anything in the buildings. They only have to change that central concept now, again, Markham could never do that at a one building scale. They're only that at the community scale. Trevor Freeman 11:08 So you mentioned, I want to pick on something you said there. You talked about a sewer heat energy system. They're pulling heat from the sewer. Just help our listeners understand high level kind of, why is there heat there for us to pull like, what's the what's the source there? Scott Demark 11:26 Yeah, so when we shower, when we flush toilets, all, all of that is introducing heat into a sewer system. So we're collecting heat from everybody's house into the sewer system. The sewer system also sits below the frost line. So call it Earth coupled. You know, it's the earth in Ottawa below the frost line sits around eight, eight and a half c and so at that temperature and the temperature of flushing toilets we we essentially get a sewer temperature in the on the coldest day of the year, but it's around 1010, and a half degrees Celsius. And obviously, for lots of the year, it's much warmer than that. And so I think, you know, a lot of people are kind of familiar with the concept of geo exchange energy, or that. Lot of people call it geothermal. But geo exchange where you might drill down into the earth, and you're taking advantage of that 888, and a half degrees Celsius. So you're exchanging heat. You can reject heat to the earth, or you can absorb heat from the earth. Well, this is the same idea, but you accept or reject from this sewer. But because the sewer is relatively shallow, it is cheaper to access that energy, and because it's warm, and on the coldest day, a couple of degrees make a big difference. Trevor and most of the years so much warmer, you're really in a very good position to extract that heat, and that's all it is. You. You are just accepting or rejecting heat. You don't use the sewage itself. It doesn't come into your building. You have a heat exchanger in between. But that's what you do. Trevor Freeman 12:58 I agree. And we've talked before on the show about the idea that you know, for an air source, heat pump, for example, you don't need a lot of heat energy to extract energy from the air. It can be cold outside, and there is still heat energy in the air that you can pull and use that to heat a building, heat water, whatever. So same concept, except you've got a much warmer source of energy, I guess. Yeah, exactly. And you know, Trevor, when you look at the efficiency curves of those air source heat pumps, you know, they kind of drop off a cliff at minus 20. Minus 22 In fact, you know, five or six years ago, they that that was dropping off at minus 10. So we've come a long way in air source heat pumps. But imagine on that coldest, coldest day of the year, you're still your source is well above zero, and therefore your efficiency. So the amount of electricity you need to put into the heat pump to get out the heat that you need is much lower, so it's a way more efficient heat exchange. Great. Thanks for that, Scott. I know that's a bit of a tangent here, but always cool to talk about different ways that we're coming up with to heat our buildings. So back to district energy, we've talked through some of the benefits of the system. If I'm a building owner and I'm have the decision to connect to a system that's there, or have my own standalone, you know, tr…
