The Power Deal

Anthropic Is Said to Buy 1.7 Gigawatts of Generators

Anthropic struck a deal worth about $3.4 billion for 1.7 gigawatts of gas-fired generators in September, the FT reported; the seller’s banker confirms the price, not the buyer.

SAN FRANCISCO, Nov. 8 — Anthropic has struck a deal worth about $3.4 billion to secure gas-fired generators for data centers, the Financial Times reported on Sunday. The AI company bought commitments for 1.7 gigawatts of heavy-duty generators in late September from OnePWR Solutions, an equipment supplier in San Antonio, according to the FT’s report as Reuters relayed it.

The FT cited one person familiar with the matter. OnePWR’s banker, Piper Sandler, lists a $3.4 billion sale in September of OnePWR’s “power generation platform to a frontier AI lab,” but does not name the lab.The Banker’s PagePiper Sandler says it was OnePWR’s exclusive financial adviser, and lists a sell-side transaction for OnePWR Solutions (CK Holdings Group, LLC), dated “09/26”: month and year, the form its other deal pages use.

OnePWR had ordered the generators from Caterpillar about two years ago but needed money to complete the purchase, the FT reported, according to TNW. Anthropic had first planned to buy power from OnePWR, TNW wrote. Anthropic did not acquire OnePWR, and none of the supplier’s employees moved to Anthropic, but the deal included the engineering and construction capabilities needed to install the generators, Reuters relayed from the FT. The orders secured equipment “available soon and over the next two years,” Seeking Alpha reported, citing the FT.

The FT called it the biggest known single purchase of power equipment by an AI company, TNW reported. Reuters could not immediately verify the report, and Anthropic and OnePWR did not respond to its requests for comment; both declined to comment to the FT, according to TNW. It is not known where the generators will be used, TNW wrote.

The Prospectus

If the report is right, an AI lab is now buying generating equipment itself, a step Anthropic’s own prospectus describes as one it may take. “In order to secure near-term access to compute, we may also elect, or be required, to procure long-lead-time generation and electrical equipment at prices above prevailing market rates on the expectation that it can be deployed on an accelerated timeline to unlock capacity in the near term,” the company wrote in the amended filing it made with the Securities and Exchange Commission on Nov. 2. The benefit depends on engineering, procurement and construction that, the filing says, “requires specialized expertise that is currently in short supply and involves significant execution risk.”Per Kilowatt$3.4 billion for 1.7 gigawatts comes to about $2,000 a kilowatt, by the paper’s arithmetic. The reported price covers engineering and construction capabilities as well as the machines, so it is not an equipment price.

The same filing says some of Anthropic’s planned data centers “rely on dedicated on-site natural gas-fired generation,” which exposes it to fuel prices and supply disruptions it does not control, and whose fuel costs it bears. It does not name OnePWR.CommitmentsAs of and after Sept. 30, Anthropic had entered into purchase commitments and leases with an aggregate committed spend of about $895.4 billion, substantially all of it for compute and infrastructure, the filing says. About $447.5 billion of it is expected to be incurred before Dec. 31, 2030, and substantially all the rest between 2031 and 2045.

Caterpillar’s chief executive, Joe Creed, spoke of “strong order rates and a record backlog” on Oct. 29, when the company said its power-generation sales rose “mainly in turbines and turbine-related services and in large reciprocating engines, primarily in data center applications.”

The Vote

Gas plants that feed a data center directly, behind the meter, also figure in a bill before the Senate. At 5:30 p.m. Monday the Senate votes on cloture on the motion to take up H.R. 2347, the vehicle for the permitting bill that would make data centers pay for their grid upgrades. The senators’ reworked text closes a loophole that might have let data centers with behind-the-meter gas plants profit by selling surplus power to the grid, Heatmap reported: a provision meant for residential batteries now limits each qualifying facility to a rated capacity of at least 5 kilowatts and no more than 5 megawatts.

Bloomberg reported on Nov. 6, citing people familiar with the matter, that Anthropic would start formally marketing its offering this week; by 5:16 a.m. Monday, no further amended prospectus had appeared on the SEC’s EDGAR system. Anthropic itself has not confirmed the deal.
