Part 2 of 3 — The statutory divide and FERC’s PJM Co-Location Order
Part 1 described the surge in data center demand pushing very large electricity consumers onto the transmission grid, and the Department of Energy’s October 2025 direction ordering FERC to write rules for connecting them. The direction is an aggressive one. It tells FERC to assert authority over a kind of customer the Commission has historically left to the states, and it does so while a reliability crisis makes a quick federal answer attractive to almost everyone.
That ambition runs into a problem of power. FERC cannot regulate large-load interconnection at all unless the Federal Power Act authorizes it, and the Act draws a hard line between the parts of the electricity system FERC controls and the parts reserved to the states. Where large data centers fall on that line is the central question, and it is also where FERC, in its first concrete action, found a way to move without answering it.
The statutory framework: The federal-state jurisdictional divide
The DOE direction’s fate depends on three things: the statute’s text, the two Supreme Court decisions construing it, and the analogy at the heart of DOE’s claim.
