A power plant for a data center is usually bought long before anyone has signed to buy its electricity. Atlas Energy Solutions, a company based in Austin, Texas, has now put a number on what it costs to carry that gap. On 22 October it closed a $424 million bridge facility with Goldman Sachs and Barclays to pay for power generation and balance-of-plant equipment at two data center projects. Atlas had drawn $171 million at closing and expects first power at both sites in late 2027.
What The Release Leaves Out
The announcement is short. Atlas does not name the customer or the sites, gives no megawatt figure for the loan, and calls the equipment only power generation and balance of plant, without saying engines or turbines. What it does give is the structure. The facility is a delayed-draw term loan, so Atlas pays out as equipment invoices fall due. The first maturity is 180 days, extendable by another 184 days if the energy supply agreements for the two projects are signed and the lenders agree. Interest runs at the SOFR benchmark plus 2.5 percentage points, rising by half a point after six months, and Atlas may ask for up to $286 million more.
The company plans to replace the bridge with long-term financing secured on the contracted income of each project, and says most project spending comes after the supply agreements are signed and construction starts.
The September Agreements Behind The Loan
The facility rests on two cost reimbursement agreements that Atlas announced on 25 September with a customer it describes only as a leading frontier AI lab. Under them the customer takes over the related equipment and backs the financing. One agreement covers balance-of-plant items - emission control systems, electrical distribution equipment, battery storage and other supporting infrastructure - for generator orders Atlas already holds under its framework agreement with Caterpillar. The other supports an additional 283 MW of Caterpillar generating capacity for a separate data center project. Atlas also signed a purchase agreement for 328 MW, for delivery in 2027 under the same framework.
Those two capacity figures add up to 611 MW, a total Atlas does not state itself, and the release does not say what type of Caterpillar equipment is meant. No long-term power purchase agreement has been signed yet; the company says it is working toward them.
Paying For Steel Before The Contract
The sequence is the story: generators and switchgear are ordered and paid for while the power sales contracts are still open, and the bank lends because the customer stands behind the purchase. That is how a delivery slot gets secured when slots are the scarce thing, and it shifts the risk to whoever signs the reimbursement agreement.
Heat rejection is not among the equipment categories the release lists. On schedules like this it is easy for the cooling side to be settled after the generators are bought, and the site conditions the engines are rated for are worth pinning down while the equipment is still being ordered, not after it has arrived.
