Electric utility

Territory from the Colorado Energy Office utility map (data edited July 2026). The utility on your bill is the final word — we verify by address.

01

The utility behind Firestone’s bills

According to the Colorado Energy Office’s utility-territory map, Firestone is served by United Power, an electric cooperative that banks exported solar as kWh credits that offset later use one-for-one.

Territory maps are a starting point, not a guarantee — the name on your electric bill is the final word, and we confirm it before any design work.

02

What Firestone’s setting means for panels

At roughly 4,860 feet, Firestone sits on Colorado’s lower country, where open exposure makes shade rare but wind and hail are real design loads. Racking, attachment and panel selection matter more here than squeezing out the last percent of output.

03

Getting a solar permit in Firestone

We handle permitting in Firestone end to end. Depending on the address, that means the town’s own building department, Weld County’s building office, or the State Electrical Board, which issues electrical permits in many smaller Colorado jurisdictions.

04

Its population grew about 23.0% between 2020 and 2025 (16,362 → 20,129). It ranks #10 by population among the communities in Weld County, and its nearest neighbors are Frederick (4 mi), Mead (5 mi), Dacono (6 mi).

Our crews are based in Denver, roughly 29 straight-line miles away. That keeps site visits and follow-up simple.
