What changed: Black Hills Corp. executed definitive agreements, effective September 30, 2026, to provide up to 590 MW of grid-connected service to Google in Cheyenne.
Why it matters: The package includes 564 MW of new company-owned gas generation at Cheyenne Prairie and about 2.1 GW of third-party resources managed through a private microgrid. Initial service is targeted for late 2027, with the peak ramp in 2030. Resource capacity is not the same as the customer’s load.
