Creekstone secures gas capacity for Utah data center power project

Creekstone Energy has secured 43,000 Dth/day of firm natural gas transportation capacity to support the first generating block at its planned Delta Gigasite data center campus in Millard County, Utah.

The capacity was contracted on the Kern River Gas Transmission pipeline and is expected to provide fuel for approximately 220 MW of behind-the-meter generation, according to Creekstone. The company plans to begin generating power onsite in 2027.

Additional project information published by Creekstone indicates that the initial power plant will comprise 29 natural gas reciprocating engines with combined capacity of approximately 230 MW. The difference between that figure and the 220 MW announced with the transportation agreement may reflect gross generating capacity versus power available to data center tenants, although Creekstone has not explained the distinction.

At 230 MW, the engines would have an average nameplate rating of approximately 7.9 MW each. Creekstone has not publicly identified the engine manufacturer, model or emissions configuration.

The developer lists Quanta Services as the engine supplier and says the equipment can be delivered nine months after an order is placed. Quanta’s Dashiell subsidiary is also serving as the project’s substation engineering, procurement and construction contractor, with transformers and switchgear reportedly in production.

The gas interconnection has a stated design pressure range of 650 to 1,333 psig. Creekstone said an interconnection agreement and a precedent agreement were executed in September 2025 and that construction of the interconnection is underway.

Hybrid power system planned

The natural gas engines will form the initial baseload component of a broader onsite energy system planned for the campus.

Creekstone has installed Torus battery and flywheel equipment to provide load smoothing, grid-forming capability and system stability. The developer also plans to add utility-scale solar generation on adjacent land and use propane for backup and peaking service.

NAES Corp. has signed a memorandum of understanding to serve as the exclusive operations and maintenance provider for the power plant. Ramboll is conducting air-permitting engineering and emissions modeling for the generation facilities. Creekstone said the air permit remained in final modeling.

The 1,143-acre Delta Gigasite is zoned for heavy industrial use and has received a conditional use permit covering both data center development and onsite power generation. Creekstone ultimately envisions more than 10 GW of generating capacity at the campus, although the contracted gas supply supports only the initial approximately 220-MW block.
