Logan County’s utility map
By area, the Colorado Energy Office territory map shows Highline Electric Association (91%), Morgan County Rural Electric Association (3%), Town of Fleming (municipal electric) (0%). Area isn’t population — towns are often served by a different utility than the surrounding countryside.
The largest by area, Highline Electric Association, is a electric cooperative that pays for excess generation at an avoided-cost rate well below retail.
Logan County by the numbers

The county is fairly uniform in elevation — Sterling near 3,930 feet and the geographic center around 3,850 feet — so conditions are relatively consistent across it.

Who issues solar permits in Logan County
Permitting in Logan 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.
Solar for businesses in Logan County
For a business in Logan County the first question is the rate class, not the roof: Highline Electric Association, a electric cooperative, must net-meter commercial systems to 25 kW under state law and sets its own terms above that.
Out on the plains the loads that matter are grain elevators, feedlots and dairies, irrigation pumping, equipment dealers, county and school buildings, and small-town main streets. Land is cheap and roofs are often metal, so ground mounts and barn roofs are common, and the co-op's rules on irrigation and commercial accounts decide the design. 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 Logan County commercial page and worth a conversation with your tax advisor.
