North Carolina’s utility regulators turned down Duke Energy’s request for a new gas turbine this week, and the reasoning is the good part. Duke had leaned on its commitment to the White House’s “Ratepayer Protection Pledge” as justification. The commission’s answer, more or less: you never showed us how much of this plant is actually for data centers, so we can’t tell if it protects ratepayers or just bills them for somebody else’s growth. A pledge named for protecting people, cited to justify a plant, rejected for failing to prove it does the thing in its own name.

California did something in the same spirit the same day, with statute instead of a denial. Newsom signed seven bills requiring data centers to pay their fair share of grid upgrade costs, disclose water use, and give up the blanket environmental exemptions they’d been quietly operating under. Los Angeles County had already frozen large-scale AI data center permits in unincorporated areas. Different tools, same move: somebody asking to see the receipts before the ratepayer eats the bill.

I’ve spent the last few days on what I started calling paperwork season — an appeal that wasn’t an appeal, a House bill everyone knew was dead in the Senate, a Texas fee swap that gave up trying to tell a warehouse from a hyperscaler. Gestures engineered to resemble action without committing to any. This week two states did the less glamorous thing instead. They checked the math. New England states piling onto Maine’s complaint about the extra return utilities collect for joining a grid operator is the same instinct, aimed at a much quieter subsidy nobody outside a FERC docket was ever going to notice.

Good week for arithmetic, is what I’m saying.
