Records released under Arkansas's freedom of information law at the end of August put numbers on a question the data center industry has been answering vaguely for two years: when a hyperscaler needs a gigawatt-scale load, who pays for the power plants? In this case, Google does. The company will contribute $526 million up front toward Entergy Arkansas's Cypress Solar project and a further $190 million for transmission upgrades needed to serve its West Memphis data center.
The disclosure also triggered a legal fight, and the dispute is as instructive as the numbers.
Cypress Solar is planned as 600 MW of solar paired with a 350 MW battery storage system in Jefferson County, near Pine Bluff, connecting to Entergy's White Bluff substation. Entergy has estimated the project at approximately $1.602 billion and expects it to begin operating by the end of 2028. The $526 million contribution is roughly a third of that cost. The data center it supports is Google's $4 billion, roughly 1,100-acre campus outside West Memphis.
The public argument about the size of Google's commitment turns on how the payments are counted, and both readings are worth understanding before either is repeated.
| Figure as reported | What it represents | Source |
|---|---|---|
| $526 million | Up-front contribution toward Cypress Solar, described as about one-third of the project cost | Public Service Commission records reported by the Arkansas Democrat-Gazette, 31 August 2026 |
| $190 million | Transmission system upgrades needed to serve the data center | Same records |
| $443 million in accelerated payments plus $83 million in minimum demand payments | Breakdown of the first-year flows toward the solar facility, from a prehearing memo in the same records | Public Service Commission documents |
| Approximately $2.103 billion | Entergy's estimate of the full 20-year value: $443 million in advanced payments plus $83 million in minimum demand charges annually across the term | Entergy Arkansas public statement |
Entergy's position, published on its own site, is that reporting understated Google's investment because it counted twelve months of payments rather than twenty, and the company cites the $2.103 billion figure as the correct total. Entergy says the structure covers 100% of Google's cost to serve through upfront capital and minimum annual demand payments, generates more than $1.1 billion in net system benefits for other customers, and sits within what the utility calls its Fair Share Plus pledge.
The regulatory record adds a complication that is easy to miss. The Arkansas Public Service Commission rejected Entergy's proposed accounting treatment for Google's upfront payments and required portions of the agreement to be renegotiated, maintaining that position in January 2026 while separately allowing Cypress investment tax credits into the project's pricing. The commission's staff pressed witnesses on why the payments were not characterized as a contribution in aid of construction — a classification that would reduce the cost other customers carry. As documents summarized by KVOM note, the available records do not establish that Google's contribution translates into a specific reduction in other customers' rates.
| Date | Event |
|---|---|
| December 2025 | Arkansas Public Service Commission approves the special rate contract between Entergy Arkansas and Altitude LLC, a Google subsidiary |
| March 2026 | Commission approves the Cypress Solar facility |
| June 2026 | Entergy residential customers begin paying an added $5.77 per month to cover three new generation projects, Cypress Solar among them |
| 31 August 2026 | Records obtained under the Arkansas Freedom of Information Act are reported, disclosing the $526 million and $190 million figures and the payment breakdown |
| 1 September 2026 | Entergy files a federal trade secret suit against publishers over the disclosure; a federal judge declines to block further reporting |
| 16 September 2026 | Entergy voluntarily dismisses the complaint without prejudice |
| End-2028 | Targeted start of Cypress Solar operations |
Entergy's explanation for pursuing legal action was that the material was confidential customer information shared inadvertently, and that protecting it is a legal obligation comparable to protecting any customer's data. That is a defensible position for a utility. It is also, in practice, why this particular contract structure is now public: the fight over disclosure turned an accounting question into a precedent nobody in the sector can ignore.
Inside Cypress Solar, the battery is 350 MW against 600 MW of solar. The public record does not disclose the battery's discharge duration, and the megawatt ratio on its own cannot supply it: a storage pairing at roughly half the solar capacity appears under short firming designs and under four-hour designs alike, so the ratio is not evidence of either. What the record does establish is the procurement context. Entergy's own resource plan adds more than 1,000 MW of new gas capacity, unit repowering and coal-to-gas retrofits alongside the renewables, and the two tracks are running in parallel rather than one displacing the other. In that setting the battery is bought as peaking capacity against whatever else the utility would have built for the same job — which, for a utility of Entergy's shape, points to a gas peaker rather than another battery.
Google's approach elsewhere completes the picture of how hyperscalers are actually buying firm power. It has an agreement with Kairos Power intended to enable up to 500 MW of advanced nuclear capacity, with a first small modular reactor online by 2030 and a first deployment delivering up to 50 MW to TVA's grid. On 1 September, Fervo Energy announced a 396 MW power purchase agreement with Google for enhanced geothermal capacity in Utah, described by Fervo as the largest such agreement to date. In Virginia, Appalachian Power filed an application on 4 September estimating $264 million of transmission upgrades for Google's Botetourt County campus, citing the Ratepayer Protection Pledge under which Google pays for delivery upgrades.
Arkansas is not an outlier so much as an early disclosure. Ireland began requiring new data centers in December 2025 to match their maximum import capacity with local or on-site generation and storage. Thailand has halted approvals for dozens of projects while it reassesses power and water supply. Malaysia is refining battery configuration requirements for corporate renewable supply. The direction is consistent: large loads are increasingly expected to bring their own firm capacity, or pay for it.
The $526 million and $190 million figures, the $1.602 billion project cost, the 600 MW solar and 350 MW battery configuration, the December 2025 contract approval and the litigation timeline are consistent across the listed sources. The gap between the reported up-front figure and Entergy's 20-year total is a difference in accounting period rather than a factual dispute, and both are set out above. The role attributed to the battery here is our reading of Entergy's parallel gas, repowering and coal-to-gas plans, not of the 350 MW / 600 MW ratio — the record discloses no discharge duration, and the ratio alone does not indicate one. Cypress Solar's offtake and REC arrangements are as described in the commission documents reported by the Arkansas Democrat-Gazette and have not been independently confirmed by Google.
