The power decisions that could shape the next century

· Axios

The AI-driven power boom is forcing a once-in-a-generation decision about how America's electricity system should grow.

The big picture: For decades, utilities planned around predictable increases in demand. AI is changing that.

State of play: Data centers now seek amounts of electricity that used to be associated with entire cities — raising questions about who pays for new infrastructure, who gets access to scarce power and how quickly projects can connect to the grid.

Driving the news: Debates are unfolding at the nation's largest grid operator, PJM, and at the Federal Energy Regulatory Commission.

  • Some proposals would allow data centers to connect directly to power plants or generate their own power on site, at least initially operating outside the broader electricity grid.

Zoom out: Those debates reflect a broader question facing regulators across the country: how to handle massive new electricity users.

What we're watching: Multiple decisions will unfold over months and years, with a key decision by the federal agency expected as soon as this month.

  • The outcomes will influence electricity prices, reliability and the pace of AI development.

The bottom line: Decisions now being made by regulators, utilities and technology companies could determine whether the AI boom accelerates a historic expansion of the electric grid — or creates a parallel power system alongside it.
