New Causal Evidence Finds Datacenter Growth Lowered US Residential Power Prices, as New York Freezes Construction on the Opposite Premise

The claim that datacenters are inflating household electricity bills runs backward against the best available evidence: an EPRI white paper published June 23 finds that doubling a state's datacenter capacity caused residential electricity prices to fall 3.5 percent, and that the typical US household now sits in a state where datacenter capacity grew about 160 percent between 2019 and 2024, leaving its power price roughly 6 percent lower than it otherwise would have been.

EPRI controlled for the obvious objection, that datacenters cluster where power is already cheap, and still found load growth doing the work, as fixed grid costs spread across more demand and newly built generation undercuts the older plants it replaces. "Despite the popular narrative that data center growth is the driver of recent price increases, evidence points in the opposite direction," the authors write. Texas has the most of that benefit to capture, with more large load queued for its grid than any other state carries.

The Texas Energy Buyers Alliance was the first to propose that large loads pay transmission charges tied to their approved capacity, precisely so the cost of connecting them doesn't land on everyone else. The stakes are large: ERCOT estimates up to 110 GW of new large loads could seek to connect over the next five years, more than double today's system peak of about 86 GW, on top of roughly $37 billion in transmission costs already baked into rates and pushing them up about 3.5 percent a year for every customer. Bryn Baker, senior director of policy at the Clean Energy Buyers Association and the alliance's lead, wants minimum demand charges set where studies suggest they leave other customers' rates "neutral or lower." Asked whether new demand can cover the system upgrades it triggers, she says simply, "We want them to."

That instinct is becoming national practice. FERC's June large-load tariff actions directed the six jurisdictional grid operators to justify or reform their rules for datacenters and advanced manufacturing, and Berkeley Lab has framed the work across five fronts: load forecasting, interconnection, resource planning, market operations, and cost allocation. Private capital is moving the same way, with Blackstone and partners committing $5.34 billion for a 49 percent stake in five behind-the-meter natural gas projects totaling about 2.6 GW, Williams keeping 51 percent and citing a 6 GW-plus backlog, and Chevron planning a $7 billion Texas power buildout with Microsoft and GE Vernova. Operators who fund their own transmission and generation are the ones that make the EPRI cost mechanism real.

On Tuesday, New York became the first state to halt construction of large new AI datacenters, those drawing 50 MW or more, when Gov. Kathy Hochul signed a one-year moratorium premised on the claim that the facilities "threaten to hike up utility bills, deplete our natural resources." During the freeze the state's environmental regulator will withhold discretionary permits not already deemed complete while it drafts a Generic Environmental Impact Statement, and Hochul says she will seek to repeal sales-tax exemptions for large datacenters. The timing is unkind to her premise, because the same week produced causal evidence that datacenter growth has pushed residential rates down rather than up, and a pause on the roughly 27 projects proposed across New York since 2024 forecloses that benefit for her own ratepayers.

Texas faces the same organized opposition through a different door. Public Citizen's new Texas Data Center Policy Guide coaches opponents that their hardest task is simply learning about a project early, since no single state list of proposed datacenters exists, and it points them toward zoning, available to cities but not counties unless the state grants it, plus environmental permitting that rarely stops a project but can slow it, JETI tax agreements, and water-rights allocations from groundwater conservation districts. The tax line deserves the accounting the guide skips: an abatement is a discount against a bill that still nets sharply positive once construction spend, permanent tax payments, and local infrastructure are counted. The pressure points are real, and the operators who disclose early and site cleanly are the ones who defuse them.

The transparency gap is real. Texas regulators are letting some AI datacenters permit new emission sources through a standard registration, the kind of rule written for dry cleaners and other small sources, sometimes with limited public notice. Omaira Garcia, an Air Force veteran near Abilene, learned of OpenAI's Stargate campus and its 10-turbine gas plant about 500 yards from her house only after construction started in the summer of 2024. Developer Crusoe says the project has funded new fire trucks, school expansions, and road improvements across the city, but the community investment did not change how late she found out. In San Antonio, residents near Westover Hills pressed TCEQ at a May hearing over a Vantage site's 32 on-site diesel generators, with District 6 council member Ric Galvan flagging air quality. With roughly 300 datacenters operating in Texas and about 200 more in development, the state is on track to pass Virginia as the country's largest market by 2030, and the notice problem scales with it.

The operators racing to the front are the ones closing that gap on their own. At Lancium's Clean Campus in Hall County, QTS says its buildout will use closed-loop cooling and draw no water from Turkey's municipal system, removing the most common local objection before it is raised. Oklahoma shows the policy version of the same instinct: datacenters there mostly buy municipal water and go untracked, and Baxtel lists 55 datacenters in the state with not one water permit among them, which is why SB 259, signed in May by Gov. Kevin Stitt, grants groundwater permits only to datacenters whose cooling conserves or recycles water. The disclosure standard is coming either way, and the operators who meet it early own the trust the laggards will have to buy back.

The largest new campuses now resemble utilities more than tenants. Meta is expanding its Hyperion site in Richland Parish, Louisiana, into a 5 GW supercluster backed by more than $50 billion, up from about $27 billion a year ago and now a joint venture with Blue Owl Capital, with a first phase near 2 GW by 2030. "At 5 GW, this is no longer just a large data center," says Neil Osnato of Persistence Analytics Group. "It becomes a regional infrastructure-planning event." In Wyoming, Google surfaced as the customer behind the 2.7 GW Project Tembo campus near Cheyenne, scaled up from 1.8 GW with a path to 10 GW, and served by Tallgrass Energy's dedicated bring-your-own-power hub of combined-cycle gas and fuel cells, more than $7 billion in generation alone.

Texas already runs on that blueprint. At Lancium's Clean Campus near Turkey in Hall County, QTS plans a $10 billion buildout of up to 11 buildings anchored by a 1 GW grid connection, with Lancium and QTS funding all of the energy-infrastructure work and Lancium supplying its own power, including on-site solar and battery storage. As Stephen Sopko of HyperFrame Research puts it, "You can multisource chips, but you can't multisource a transmission queue slot." The operators who bring their own generation and transmission, the Texas default, are the ones who reach load without waiting in that queue.
