Black Hills Corp. has signed long-term agreements with Google to supply a planned data centre in Cheyenne, Wyoming, through 2048 (Black Hills Corp. press release, 06/10/2026). The project will require a total resource portfolio of approximately 2.7 GW, with power demand expected to ramp up between 2027 and 2030.
Black Hills will provide up to 590 MW of grid-connected supply through company-owned generation and market purchases. The utility will also manage approximately 2.1 GW of contracted third-party resources through a privately managed microgrid. To support the project, Black Hills plans to invest USD1.8bn between 2027 and 2029 in 564 MW of new gas-fired capacity at its Cheyenne Prairie Generating Station. The remaining 26 MW will be supplied through a combination of market energy purchases and retail utility service provided under the company’s applicable industrial tariff.
