Everyone agreed the ratepayer shouldn't fund AI's power. Now they're fighting over the arithmetic.

The bill arrived before the argument did. Through the first half of 2025, PJM — the wholesale power market spanning 13 states and the District of Columbia — ran its capacity payments, the charges for power held ready on standby, through 67 million people's bills: New York's rose 14.4 percent, New Jersey's 13.3 percent ^[1]. The market's independent monitor put 64 percent of the ballooning payments on actual and projected data-center demand ^[1]. Maryland's consumer advocate forecast up to $216 a year per household ^[2]. The costs landed in 2025. The concessions came after. By this year the question of who pays had closed, and everyone signed. Anthropic's Dario Amodei said it plainest.

We’ve been clear that the U.S. needs to build AI infrastructure at scale to stay competitive, but the costs of powering our models should fall on Anthropic, not everyday Americans. — Dario Amodei

FERC, the federal commission that sets wholesale power rules, voted unanimously in June to speed data-center hookups only on condition that the centers pay their full upgrade costs; Chair Laura Swett framed it as fair-share arithmetic ^[3].

As chairman, I am taking extremely seriously the mission that Congress has entrusted us to ensure that rates are reasonable and that Americans pay their fair share or less. — Laura Swett

The House Energy and Commerce Committee approved the Ratepayer Protection Act with zero dissenting votes ^[4]. Chair Brett Guthrie put the committee's point at the markup ^[5].

Families and small businesses across the country shouldn’t be left to foot the bill for this new development, though the benefits of these innovations will be felt by all of society. — Brett Guthrie

Ranking Democrat Frank Pallone did not argue against the bill ^[4].

If America wants to lead the world in AI and strengthen our national security, we have to build the energy infrastructure to support it. But we must do that without passing the costs on to working families and small businesses. — Jon Husted

Twenty-two governors signed the pledge ^[6]. A state that would not restrain the buildout at all — North Dakota's legislature rejected both a moratorium and an NDA ban — still agreed it should pay its own way, and its governor, Kelly Armstrong, signed too ^[7][6]. In Florida, Byron Donalds took $5 million from an AI-backed committee and still campaigns on pocketbooks ^[8].

I’ll fight for a ratepayer protection plan because in my Florida, if you don’t protect our pocketbooks and our people, you won’t build data centers. — Byron Donalds

Notice what the unanimity cost: nothing. The pledge says nothing about water, local permitting, or who pays if a project is abandoned ^[6]. What the agreement never settled was what a fair share costs. That fight runs in the quietest arena in AI politics: the utility rate docket, the proceeding where a regulator approves what a company may charge. In Virginia, Governor Spanberger asked for a "but-for" rule — data centers would pay for the lines the grid wouldn't need but for their demand — against Dominion's $1.5 billion recovery; Microsoft and Amazon opposed the immediate rule and countered with a voluntary payment system instead ^[9]. The wave is national, and it is arithmetic all the way down. Oregon's commission unanimously raised large data centers' power rates 29 percent, cutting residential rates 1.3 percent and saving other customers an estimated $900 million over 30 years ^[10]. Wisconsin's regulators ordered Microsoft and Vantage to cover full generator and transmission costs ^[11]. Oklahoma's legislature passed a 75-megawatt rule unanimously. Alabama now demands full cost coverage from 150-megawatt projects, while Alabama Power fights over whether the contract itself can be read in public ^[12]. PJM's price cap was explicitly temporary — a bridge while "new rate structures" shift upgrade costs onto the large-load companies ^[13]. But the fixes lag the physics: as of April, Maryland prices were still rising, because data centers build in months while power plants take five to seven years ^[14]. Then look at what the same companies do in private. Microsoft filed a FERC protest against the transmission-cost plan for its own Mount Pleasant, Wisconsin facility — the very plan written to shield other ratepayers ^[15].

The entire purpose of these agreements, by ATC’s own description, is to serve the Mount Pleasant data center. — Microsoft

The utility answered ^[15].

This is a customer protection mechanism that follows the ‘cost causer, cost payer’ methodology. — American Transmission Company

And in November, PJM's stakeholders rejected all 12 proposals to regulate data-center demand; none drew two-thirds support, with billions at stake ^[16]. The fight the public actually sees is the other one — the consent war. AWS CEO Matt Garman claims anti-data-center movements blocked $68 billion of projects last quarter, and that foreign governments are deliberately seeding misinformation to slow the industry down ^[17]. Governor Hochul signed the first statewide moratorium ^[18]. Governor Healey conditioned state permits on local approval ^[19]. That fight is loud, and it is real. It is not the one that binds; the question of who pays was already closed. Finally, the escape. The same administration that pushed the pledge has priced a way out of the meter. EPA Assistant Administrator Aaron Szabo declared the Clean Air Act's Acid Rain Program inapplicable to islanded plants, explicitly to give developers flexibility and speed, and explicitly in support of Trump's Ratepayer Protection Pledge ^[20].

The EPA believes that, considering the plain text of these definitions, the Acid Rain Program does not apply to power generation facilities that are not connected in any way to the larger electricity grid. — Aaron Szabo

Trump, meanwhile, has pushed eased regulations for data centers building their own off-meter power plants ^[21]. Step it through. Every settlement above presumes a shared meter — upgrade costs spread across it.

They're spread across the region to every business and resident that has an electricity meter. — Ari Peskoe

A plant off the meter causes no shared upgrade, so there is nothing to allocate and no meters to spread it across. And a plant that never touches the grid never reports its emissions either, so its pollution leaves the federal books in the same stroke that it leaves the meter ^[20].
