Grand County’s utility map
By area, the Colorado Energy Office territory map shows Mountain Parks Electric (95%), Xcel Energy (Public Service Company of Colorado) (7%), Yampa Valley Electric Association (3%). Area isn’t population — towns are often served by a different utility than the surrounding countryside.
The largest by area, Mountain Parks Electric, is a electric cooperative that banks exported solar as kWh credits that offset later use one-for-one.
Grand County facts that matter for solar
Grand County grew about 5.0% between 2020 and 2025 (15,714 → 16,496). It has 6 communities on our map, the largest being Granby, Fraser, Kremmling.
Terrain varies: Hot Sulphur Springs sits near 7,700 feet while the county’s geographic center is around 8,610 feet, so snow load, shading and access can differ a lot from one address to the next.
It’s part of our Central Mountains region. The county center is about 64 miles from our Denver office.
Permitting across Grand County
Permitting in Grand County depends on whether you’re inside a town. Towns with their own building departments issue their own permits; unincorporated areas go through the county, and the State Electrical Board handles electrical permits in many smaller jurisdictions.
Business, farm and nonprofit solar in Grand County
Grand County businesses are split between Mountain Parks Electric and Xcel Energy (Public Service Company of Colorado) — a electric cooperative and an investor-owned utility — with different commercial net-metering terms, so two shops a few miles apart can have different paybacks.
Mountain-county commercial property means lodging, restaurants, ski-area support buildings, workforce housing and small main-street retail — buildings with expensive winter power, big snow loads and roofs that often carry heated-driveway and snowmelt loads. Resort-town design review adds a step to most projects. Demand charges, roof structure and who pays the bill decide the project more than panel count does. As of September 2026, business owners can still use the federal §48E credit for solar placed in service by the end of 2027, with 100% bonus depreciation restored — details are on our Grand County commercial page and worth a conversation with your tax advisor.
