Google Is Paying $716 Million for the Solar Farm Powering Its Own Data Center. The One Entergy Tried to Bill Everyone Else For Just Got Rejected.

Google announced its $4 billion Arkansas investment, anchored by a new data center in West Memphis, in October of last year. Powering it meant building new generation fast, and Entergy Arkansas spent the following twelve months trying to do that two different ways: one project that broke ground this summer with Google's own money already attached to it, and a second, larger one that a state commission just told Entergy it hadn't earned the right to charge anyone for yet. Both projects were pitched the same way, as new solar capacity the data center's growth required. Only one of them survived contact with a regulator who actually checked the arithmetic.

The first project is Cypress Solar, a 600-megawatt solar field paired with 350 megawatts of battery storage in Jefferson County, near Pine Bluff. It's real in the way that matters most for an infrastructure claim: construction started on July 11th, and the project is scheduled to begin delivering power in February 2027, ramping to its full 600 megawatts by October 2029. For most of this year, nobody outside Entergy and Google knew exactly how much of that project Google was actually paying for. That changed on September 1st, when the Arkansas Democrat-Gazette, using documents obtained through a Freedom of Information Act request to the Public Service Commission, reported that Google had agreed to pay Entergy $716 million directly: $526 million toward Cypress Solar's construction and another $190 million for the transmission upgrades needed to connect it, broken into $443 million in accelerated payments and $83 million in minimum demand payments.

A fight over whose number is real

Entergy didn't let that number stand unchallenged. The company called the newspaper's reporting a "serious and careless mathematical error" and argued that, measured over the full life of the agreement rather than just the upfront construction period, Google is paying well over $2 billion. I can't fully reconcile those two figures from what's public, and that gap is itself the point: a $716 million number backed by leaked commission filings and a $2 billion-plus number asserted by the party being covered are not the same kind of evidence, even if both turn out to contain some truth. There's a real, unresolved accounting question sitting underneath the dispute, too. Commission staff pressed Entergy on why Google's payments aren't classified as a contribution in aid of construction, the standard accounting treatment that would directly and transparently reduce what Entergy's other customers pay. However the dollar total eventually gets settled, that classification question is the one that actually decides whether Google's money shows up as a clean offset on somebody else's bill or gets absorbed into Entergy's broader rate base in a way that's harder to trace.

Entergy's response to the leak went further than a press statement. On September 2nd, the company asked U.S. District Judge Lee Rudofsky for a temporary restraining order against the Arkansas Democrat-Gazette and the Arkansas Times, seeking to block them from publishing the figures on the grounds that some of the material was a trade secret, disclosed by the commission in error to a records requester named Jessica Kivell. Rudofsky denied the request the same day; his ruling treated it as functionally a request for prior restraint on the press, a bar the company couldn't clear. Entergy didn't push further. On September 16th, two weeks after the ruling, it filed a notice dismissing the entire lawsuit against both outlets and Kivell, without pursuing the damages claim it had left open.

I think that sequence is worth sitting with on its own, separate from whether Google's number is $716 million or $2 billion. A company tried, briefly, to keep sealed the exact records that let the public check its own math on a billion-dollar infrastructure deal, a federal judge said no within a day, and the company backed off two weeks later rather than fight it further. That's the system working about as well as it's supposed to, but it's also a real data point about how badly a party involved in a data center deal sometimes wants to control what gets checked and what doesn't.

The second deal that didn't pencil out

While the Cypress Solar numbers were playing out in court and in the newspapers, Entergy had a second, separate solar request in front of the same commission: a 20-year power purchase agreement for Big Island Solar, a 440-megawatt project in Mississippi County developed by Pattern Energy. Entergy signed the deal in December 2025 and filed for the commission's approval the following month, arguing the project would help meet future energy and capacity needs and projecting net customer benefits of $29 million to $214 million over the contract's life, with the company's briefing explicitly tying some of that need to supporting Google's clean-energy goals for the West Memphis campus.

On September 19th, the Arkansas Public Service Commission said no, in a 52-page order that reads less like a close call than a checklist of unmet burdens. Entergy hadn't shown the contract's costs were reasonable, the commission found, or that it would save customers money relative to the alternatives Arkansas law requires a utility to consider before signing a 20-year commitment. Key assumptions behind the deal's projected benefits, including the capacity value and the renewable energy credit revenue the economics leaned on heavily, weren't adequately supported, and some of that REC revenue was still being negotiated with Google at the time Entergy asked regulators to approve the deal anyway. The commission also questioned whether Entergy had demonstrated a genuine need for the capacity at all. That's four separate, specific failures in one order, not one technicality.

Put the two projects next to each other and the contrast is almost clean enough to be a teaching example. Cypress Solar has a shovel in the ground, a connection date on the calendar, and $716 million of disputed-but-real money from the company that will actually use the power. Big Island Solar had a signed contract, a hopeful set of projections, and revenue assumptions that depended on a negotiation with Google that hadn't finished yet. One was a commitment. The other was a pitch dressed up as one, and a regulator that actually read the filing caught the difference.

None of this means Arkansas ratepayers are fully insulated from what Google's data center costs the system. Google's payments cover a meaningful share of Cypress Solar, but reporting on the underlying rate filings puts the remaining cost to ordinary Entergy Arkansas customers at close to $6 more a month, and that's a separate line item from the utility's broader general rate case, which affects roughly 730,000 customers, has already drawn objections from Walmart and other large commercial users, and reaches its next milestone on November 4th. $716 million, or $2 billion, is real money moving in the right direction. It isn't the whole bill, and nobody involved has claimed it is.

What I keep coming back to is that Cypress Solar and Big Island Solar were pitched with almost identical language, as new capacity a growing data center load required, and only one of them had to prove it. The commission's own evidence ladder runs on exactly that distinction: a number a company has already spent real money backing up sits in a different place than a number attached to a contract still waiting on someone else's signature. Virginia's regulators drew a similar line in August, cutting what Dominion could bill households for a data-center-driven transmission line by two-thirds and sending the rest to the data centers directly. Arkansas just did its own version of the same math, on a smaller project, with a commission order instead of a tariff. The useful question for the next utility that shows up with a "new solar for growing demand" pitch isn't whether the story sounds plausible. It's whether the money behind it is already committed, or just promised.
