When 47 million people across Spain and Portugal lost power for nearly half a day in April, the finger-pointing began immediately. "Too much renewable energy," declared the critics. Even U.S. Energy Secretary Chris Wright piled on: "When you hitch your wagon to the weather, it's a risky endeavor.”

There's just one problem with this blame-renewables narrative: it's completely wrong.

In this crossover episode with the Redefining Energy podcast, we examine the official Spanish grid operator report that reveals a complex web of failures.

While the blackout began with a solar plant sending frequency oscillations through the grid, what followed was a cascade of problems: conventional generators that failed to provide required voltage control, inadequate battery storage to balance massive solar capacity, weak interconnections to neighboring grids, and ultimately, poor system management by grid operators themselves.

Our guests, Laurent Segalen of Megawatt-X and Gerard Reid of Alexa Capital — co-hosts of Redefining Energy — help us decode what went wrong and what Spain needs to fix.

"Spain has installed 30 gigawatts of solar in the past 10 years and there's hardly any batteries and there's hardly any connection with the rest of the continent,” explained Segalen. “The system has become more fragile."

“We've had, in the UK, an interconnector going down, 1.4 gigawatts. Well, guess what? There was no blackout. Why? Because batteries came in straight away,” said Reid.

We’ll discuss the many factors behind the outage, and explore why Spain’s grid operator is trying to avoid blame.

Then, we’ll look at how security is reshaping European energy investment. As America leans into its role as a dominant petrostate and pulls back from post-World War II security commitments, Europe is being forced to reconsider how to structure clean energy supply chains.

We also explore the emerging split between "petrostates" and "electrostates" — countries that control energy through scarcity versus those that build abundance through manufacturing and technology. While America doubles down on fossil fuel dominance, can Europe position itself alongside China as a leading electrostate?
