Cheyenne is Wyoming's capital at 6,062 feet elevation — the windiest major US city (12.4 mph average, 50+ mph gusts) and served by Black Hills Energy for BOTH electric and gas (single utility). Altitude derates equipment capacity roughly 15% vs. sea-level specs.
Black Hills Energy serves Cheyenne for both electricity and natural gas (1-888-890-5554 / blackhillsenergy.com). This single-utility structure is genuinely useful for electrical projects: for panel upgrades, heat pump conversions that require gas cap-off and electric service upgrade simultaneously, or any project touching both systems, one call to Black Hills handles all utility coordination. Start contact the same day as the city permit application.
Exterior electrical installations in Cheyenne — conduit runs, disconnect boxes, meter pedestals — need weatherproof fittings specified for sustained high wind. The 50+ mph gusts that regularly hit Cheyenne loosen standard outdoor fittings over time. This is a small but important detail that contractors from lower-wind markets often miss.
