Black Hills said agreements effective September 30 will serve a planned Google data centre in Cheyenne, with $1.8 billion of new generation planned for 2027-2029.
Black Hills Corp. said on Tuesday it has signed definitive agreements, effective September 30, 2026, to serve a planned Google data centre in Cheyenne, Wyoming. The company posted the announcement as an exhibit to a Securities and Exchange Commission filing.
The agreements run through 2048 and include a Large Power Contract Services Agreement and a Generation Facilities Agreement. The project is planned to draw on a 2.7-gigawatt resource mix, including reserve margins, with energy service beginning in late 2027 and peak load in 2030.
Black Hills will provide up to 590 megawatts of grid-connected service through company-owned generation and market energy, and will manage about 2.1 gigawatts of Wyoming third-party resources through a private microgrid. It plans to invest $1.8 billion from 2027 to 2029 to build 564 megawatts of company-owned generation.
The company said it expects to begin earning a return on that generation investment when construction starts in 2027, and that the project could generate about $2.4 billion of unlevered free cash flow through 2048, net of the $1.8 billion of capital spending. Those figures exclude additional transmission expansion.
The filing describes planned service for a data centre that is still to be constructed. It did not announce a Google construction start date.
