Energy Evolution

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.

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.

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.

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.

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.
