The summer stress test: How heat waves are rewiring Europe's power markets Jul 14, 2026

Show notes

Traditionally, European power systems were engineered around a single imperative: survive the winter "Dunkelflaute," those prolonged cold, dark, windless stretches that push demand higher while renewable generation collapses. But rising summer temperatures are dismantling this assumption. Heat waves are forcing a fundamental recalibration of infrastructure investment, operational strategy and market design across the European power sector.

In this episode, host Eklavya Gupte speaks with Parth Goel, power analyst at S&P Global Energy CERA, about how extreme heat is reshaping demand patterns, straining supply and exposing vulnerabilities in the continent's energy infrastructure.

Goel explains why France, not Southern Europe, has emerged as the most price-sensitive region during heat waves, how solar generation creates dramatic price swings between midday troughs and evening peaks, and why Europe is shifting from a winter-peaking power system to a dual-peaking one.

The conversation also examines the compounding effects of drought on Alpine hydro, the thermal stress on nuclear cooling systems, and why summer now demands the same infrastructure planning attention as winter.

The new economics of renewable energy: Why transmission trumps technology Jul 07, 2026

Show notes

The clean energy investment landscape has undergone a fundamental reset. The era of zero interest rates has given way to a more disciplined environment where transmission access and power market fundamentals determine success or failure. In this episode, host Eklavya Gupte speaks with Declan Flanagan, founder and CEO of Bluestar Energy Capital, about how his company is responding to these shifts. Flanagan discusses how power pricing dynamics are reshaping technology choices and why certain markets like Germany are emerging as battery storage frontiers. He also examines how capex inflation, extended interconnection timelines and evolving demand profiles have rewritten the renewables investment playbook.

What California’s launch of an extended day-ahead market means for the western US Jul 01, 2026

Show notes

Every day, power market participants in the Western US must determine how much electricity they need for the following day and where it’s going to come from. In response, California’s grid operator on May 1 launched its Extended Day-Ahead Market, or EDAM, giving power providers a better way to coordinate to find the cheapest electricity.

So how is it going so far? And what does it mean for grid reliability, emissions, ratepayers and power traders? Joining the podcast to address those questions will be Elliott Mainzer, president and CEO of the California Independent System Operator, and Scott Miller, executive director of the Western Power Trading Forum. They are interviewed by Kassia Micek, a reporter for S&P Global Energy who covers Western power markets, who joins co-host Dan Testa to talk about what’s ahead for the region.

Cameco makes the case for large nuclear reactors Jun 23, 2026

Show notes

Much of the current discussion about nuclear power focuses on advanced technologies, from the potential for nuclear fusion to the development of various designs for small, modular reactors.

But if we ask what new nuclear reactors have been built recently in North America and are up and running? The answer is the two reactors at the Vogtle plant in Georgia, which use Westinghouse Electric’s AP1000 design.

In this episode, Dan Testa interviews Grant Isaac, president and COO of Cameco Corp., a uranium mining and production company that is co-owner of Westinghouse Electric. Isaac says the global nuclear industry is making significant improvements in cost and execution when it comes to building new projects and refurbishing existing reactors – and that the pieces are lining up in the US for utilities to invest in new, large nuclear reactors using Westinghouse’s AP1000 design.

How the Iran war is challenging and changing Europe’s gas market Jun 16, 2026

Show notes

After nearly four months, global commodity markets have shown both vulnerability and resilience amid the unprecedented disruptions caused by the Iran war. The European gas market is no exception. In this episode of Energy Evolution, host Eklavya Gupte examines the paradoxes shaping Europe’s gas outlook.

Gas prices in Europe have surged since the conflict erupted, yet remain far below the panic-driven highs of 2022 following Russia's invasion of Ukraine. Beneath the surface, however, a new set of risks is emerging: gas storage is filling at its slowest pace in years, and the market’s reliance on LNG has left it increasingly exposed to fresh supply shocks.

Matt Hoisch, senior gas and LNG reporter at Platts, part of S&P Global Energy, speaks with Jack Sharples, senior research fellow on the gas research program at the Oxford Institute for Energy Studies, about why prices haven’t reached 2022 crisis levels, what current storage figures mean for winter volatility, and how the gas market’s growing interconnectedness is amplifying uncertainty.

How battery storage is transforming the power grid Jun 09, 2026

Show notes

It’s hard to overstate how fast the battery energy storage industry is growing, and the impact that’s having on the power sector. In 2025, US utilities and independent developers added 17.75 gigawatts of large-scale battery storage capacity, up 52% from 2024. Multiple forecasts suggest another 100 GW or more of large-scale battery capacity will come online in the US through 2030.

To the extent utilities and power producers can meet the electricity demand projected to surge in coming years, batteries are going to be critical to the solution, supporting data centers, electric vehicles, domestic factories and other sources of increased load.

In this episode, Dan Testa digs into these trends with Noah Roberts, executive director of the Energy Storage Coalition, and Mateo Jaramillo, CEO of Form Energy, a company building and deploying long-duration batteries using innovative iron air technology.

Discussing data centers' grid impacts with Amazon Web Services Jun 02, 2026

Show notes

The growth of data centers, and the amount of electricity expected to be required to meet that demand, is probably the biggest issue in the US power sector.

US grid power supplied to hyperscale, leased and crypto-mining data centers reached about 64.4 gigawatts in 2025, nearly tripling since 2020. And that growth is accelerating.

In this episode, host Dan Testa speaks with Brandon Oyer, head of energy and water for the Americas at Amazon Web Services. Oyer breaks down what he describes as misperceptions regarding the water and power impacts of data centers, the ways in which many people rely on data centers without realizing it and how AWS works with utilities to develop new projects.

Beyond molecules: The rise of environmental commodities May 27, 2026

Show notes

In this episode, host Eklavya Gupte sits down with Marijn van Diessen, CEO of STX Group, one of the world's leading environmental commodity traders.

The conversation explores Europe's strategic pivot toward domestic energy sources, the explosive growth potential of biomethane as a gas substitute, and the surge in demand for renewable certificates driven by AI data centers — alongside the challenge of creating liquid markets for products that exist only as digital attestations.

Van Diessen explains both the parallels and distinctions between environmental and traditional energy trading. Like oil and gas, environmental commodities require logistics, storage and physical infrastructure. But unlike fossil fuels, they're far more sensitive to regulatory shifts — where a single policy change can trigger volatility as dramatic as any geopolitical shock.

How the war in Iran is accelerating Asia's energy transformation May 19, 2026

Show notes

In this episode, host Eklavya Gupte explores how the war in the Middle East has exposed Asia's deep reliance on fossil fuels while also accelerating the region's energy transition.

Ruchira Singh, energy transition editor at Platts, part of S&P Global Energy, speaks with Nobuo Tanaka, chair of the steering committee at the Innovation for Cool Earth Forum and former executive director of the International Energy Agency, about the emerging dynamics between petrostates and electrostates, and where Asia stands on the threshold of its energy future.

Echoing the 1970s oil shocks that gave rise to the LNG market, Tanaka believes this crisis will spark another tectonic shift, elevating renewables to the mainstream and fast-track Asia's electrification.

From faster electric vehicle adoption to expanding low-carbon hydrogen trade and strengthened regional collaboration, Asia is poised to respond with a decisive shift toward cleaner, more resilient energy systems, he says.

From crisis to resilience: How renewables are strengthening Europe’s energy security May 12, 2026

Show notes

The war in the Middle East has put energy security back at the top of Europe's political agenda. For many, it brings back uncomfortable memories of 2022, when Russia's invasion of Ukraine triggered an energy crisis that forced governments to scramble for solutions. But this time, something is different.

In this episode of Energy Evolution, host Eklavya Gupte speaks with Alex Blackburne, senior reporter at S&P Global Energy, who recently sat down with Miguel Stilwell d'Andrade, CEO of Portugal's EDP — one of Europe's largest utilities and a major player in renewable energy.

Stilwell d'Andrade explains why Europe's power system is more resilient now than it was four years ago, driven by the region's massive expansion of wind, solar and storage. But progress hasn't been uniform, and the EDP CEO argues that consistent policy execution, as opposed to new measures, is what Europe needs most to secure its energy independence.
