01

Windsor’s electric utility

According to the Colorado Energy Office’s utility-territory map, Windsor 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.

Heads up: the map also shows Poudre Valley Rural Electric Association overlapping the Windsor area. Utility boundaries are drawn by service lines, not city limits — we check your specific address.

02

Sun, snow and terrain in Windsor

Windsor’s elevation (about 4,800 ft) puts it on the lower, open side of Colorado — long unshaded sun hours, with hail and wind as the conditions we engineer around.

03

Permits in Windsor

We handle permitting in Windsor 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
