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 Lafayette’s bills

Xcel Energy (Public Service Company of Colorado) is the utility on the state’s territory map for Lafayette. In practice that means your system is interconnected under its rules — it banks exported solar as kWh credits that offset later use one-for-one.

We still confirm the utility from your bill, since service territories are drawn along lines and substations rather than street grids.

02

Sun, snow and terrain in Lafayette

At roughly 5,270 feet, Lafayette 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 Lafayette

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

04

Where Lafayette sits

Its population has held roughly steady since 2020 (30,365 then, 30,116 in 2025). It ranks #4 by population among the communities in Boulder County, and its nearest neighbors are Louisville (3 mi), Broomfield (4 mi), Erie (5 mi).

Distance from our Denver shop: about 19 miles direct. Close enough that service calls are routine.
