The Short Version
Meta is building a giant artificial intelligence computing complex in rural Louisiana, estimated at $50 billion. The local power company, Entergy Louisiana, plans to build new gas-fired generators to supply it.
On August 12, Louisiana’s utility regulators voted 3 to 1 to let Meta keep secret how it worked out how much electricity it needs. Officials have put that need at roughly several large power plants’ worth.
That matters to ordinary households. An adviser to the regulators estimated the deal would raise average monthly power bills by $8 to $13.
The Louisiana Public Service Commission voted 3-1 on Wednesday, August 12, 2026, to overturn an administrative law judge’s order that would have required Meta to disclose how it calculated the job projections and electricity needs for Hyperion, its artificial intelligence data center campus in Richland Parish, the Louisiana Illuminator reported. The project has been estimated at $50 billion. Republicans Jean-Paul Coussan, Mike Francis and Eric Skrmetta voted to reverse the order, Democrat Davante Lewis voted to uphold it, and Democrat Foster Campbell was absent.
The Alliance for Affordable Energy, the Union of Concerned Scientists, the Sierra Club and other groups had sought the records before the commission approves Entergy Louisiana’s plans to build generation for the campus: three natural gas-fired turbines initially, plus seven more generating units for a planned expansion. Administrative Law Judge Melanie Verzwyvelt approved their subpoena on July 10. Meta appealed, arguing the information contains trade secrets.
Executive Summary
The ruling keeps confidential the detailed load forecast behind one of the largest single-customer power buildouts in the country. The headline figures are public. Meta, Entergy and state officials have estimated Hyperion will need 5 gigawatts of power and support 1,000 permanent jobs. The derivation of those numbers is not public, and that includes how quickly demand ramps and what assumptions drive it. That derivation is what Entergy relied on when it asked regulators to approve new generation.
This matters because the generation will be built and paid for through a regulated utility. A consultant who advises the commission, Lane Sisung, filed an analysis in June estimating that the deal, if approved, would raise Entergy Louisiana customer bills by $8 to $13 per month on average. The Alliance for Affordable Energy has warned that customers could bear additional costs if Meta later backs out of its agreements.
The vote may be the final word on disclosure within the commission. The Alliance’s executive director, Logan Burke, said the group’s attorneys are weighing whether they can act before the full case concludes, including potentially in state court.
The Contested Number Is the Forecast, Not the Turbines
Most coverage of AI data centers focuses on the dollar figure, here $50 billion, or on the generation hardware. In Louisiana, the dispute that reached the commission was narrower: how Meta calculated its electricity needs. That calculation matters because a utility sizes new generation around a customer’s load forecast. Load means the amount of electricity a customer draws, and the forecast describes how much it will draw and when. Entergy’s applications to build turbines for Hyperion include power-need figures derived from Meta’s calculations, and the intervening groups argued Entergy never adequately explained how those figures were produced.
The scale explains why the forecast carries so much weight. Officials have put Hyperion’s eventual demand at 5 gigawatts, a gigawatt being a thousand megawatts. The build plan runs to ten generating units: three gas turbines to start and seven more for the announced expansion. Suppose the forecast overstates demand, or the ramp arrives later than modeled. Then capacity gets built ahead of the load it was meant to serve. Under a regulated model, the cost of stranded or underused plants can end up in the rate base shared by all customers unless contract terms prevent it. That is the concern the Alliance for Affordable Energy has raised. The commission’s own consultant has already put the average bill impact at $8 to $13 per month if the deal is approved, and that estimate itself rests on the load assumptions now kept confidential.
The people affected are Entergy Louisiana’s residential and business customers, whose bills move with the approved generation, and the commissioners, who must approve that generation without the underlying forecast on the public record. Entergy is affected too: its applications will be judged partly on figures it cannot fully show.
Two Arguments, Each With Unanswered Questions
The majority’s position has substance. Commissioner Coussan argued that the general figures for jobs and power demand are already public, that the granular data is proprietary, and that letting a third party not directly involved in commission proceedings subpoena sensitive information would set a bad precedent and could have “a chilling effect” on companies considering Louisiana. Detailed load and staffing projections can reveal commercial plans, and that concern is not unique to Meta.
The intervenors’ position has substance too. A headline figure like 5 gigawatts says little about timing, ramp rate or how firm the demand is, and regulators need those factors to judge whether ten generating units are the right size and pace. The groups have not shown that Meta’s forecast is wrong. Their argument is that it has not been explained, and that distinction matters when weighing their case. Coussan also described the effort as politically motivated, citing speakers at the hearing. That characterization does not address the cost-allocation question the filings actually raise, and the question stands on its own regardless of who asks it.
The ruling also leaves one question open: whether a middle path was available, such as review of the data under confidentiality protections by commission staff or intervenors. Neither side is reported to have publicly addressed that option, and it is the most obvious way to reconcile trade-secret protection with ratepayer scrutiny.
What It Signals for Single-Customer Power Buildouts
Hyperion concentrates two risks in one project: a single customer’s demand forecast and a regulated utility’s capital program. When generation is built mainly for one large load, the protections in the supply contract matter as much as the forecast. These include minimum payment terms, exit fees and collateral. None of those terms has been made public, and the non-disclosure agreements signed by state and local officials, including Gov. Jeff Landry, have kept much of the deal’s detail out of view.
This is one commission’s ruling, and it would be an overreach to call it a national pattern. But any regulator asked to approve generation built primarily for a single data center customer faces the same question Louisiana just answered: how much of the demand case must be public before costs can be assigned to the broader customer base. The next test here is whether the intervening groups take the matter to state court, and how the commission rules on Entergy’s generation applications themselves.
Background
Meta selected Richland Parish in northeast Louisiana for Hyperion, an artificial intelligence data center campus projected at about $50 billion. Meta, Entergy and state officials have estimated it will support 1,000 permanent jobs and require 5 gigawatts of power. Entergy Louisiana, the regulated utility serving the region, contracted to supply the campus and applied to the Louisiana Public Service Commission to build natural gas-fired generation for it. Many details of the arrangement have been covered by non-disclosure agreements signed by state and local officials.
The Louisiana Public Service Commission regulates the state’s investor-owned utilities, including approving new generation and the rates customers pay for it. Because generation approved for one customer can affect the rates of all customers, intervening groups have pressed for the demand calculations behind Entergy’s applications to be disclosed.
