What changed: The WDEQ Industrial Siting hearing for the Cheyenne Prairie expansion (permit 25-05) is set for November 9, 2026, at 9 AM MST at the Red Lion Hotel, 204 W Fox Farm Road, Cheyenne, with a possible continuation on November 10. The July notice’s venue is superseded.
Why it matters: WDEQ’s July application lists 552 MW of added gas generation, taking the plant from 140 to 692 MW, with construction targeted for Q4 2026. Black Hills’ October agreement with Google describes 564 MW at the same site, with construction in 2027. A hearing is not an approval.
