The utility behind Lone Tree’s bills
According to the Colorado Energy Office’s utility-territory map, Lone Tree is served by Xcel Energy (Public Service Company of Colorado), an investor-owned utility that banks exported solar as kWh credits that offset later use one-for-one.
Territory lines don’t follow town limits: parts of the Lone Tree area also fall in CORE Electric Cooperative territory. Check the name on your bill — we confirm it by address before designing anything.
Designing for Lone Tree’s conditions
Elevation works in Lone Tree’s favor (~6,010 ft): cool, bright conditions help output. What varies lot to lot is shade from terrain and trees, plus how snow sheds off the roof.
Permits in Lone Tree
Who issues a solar permit in Lone Tree depends on local arrangements — some Colorado towns run their own building departments, others rely on the county, and electrical permits in many small jurisdictions come from the State Electrical Board. We confirm and file with the right one.

FAQ
Questions we hear
Which utility serves Lone Tree?
Xcel Energy (Public Service Company of Colorado), according to the state’s territory map — though CORE Electric Cooperative also cover parts of the area. The name printed on your bill settles it.
Will I get credit for the solar I don’t use?
Yes, under Xcel Energy (Public Service Company of Colorado)’s rules: it banks exported solar as kWh credits that offset later use one-for-one. We model that rule directly rather than assuming full retail credit.
Does Lone Tree’s elevation affect solar output?
At about 6,010 feet, Lone Tree benefits from clear, cool conditions that help panel efficiency. Actual output depends far more on your roof’s direction, tilt and shading, which we model per address.
Will an installer actually come to Lone Tree?
Yes — we’re about 16 miles away in Denver and serve every county. It’s within our regular routes.
