Utility rules and programs for Boulder
Xcel Energy serves homes in Boulder.
| Utility | Type | Generator rules |
|---|---|---|
| Public Service Co of Colorado | investor-owned | A generator transfer switch is electrical work: use a licensed electrician and pull any permit your city or county requires. Mesa County, for example, requires a separate permit for generators, and CORE has a Standby Power Connection Procedure for backup generators and batteries. |
Program details are from each utility’s own pages (read October 2026). See the Colorado incentives table for statewide credits and a status for every program.
What to plan for in Boulder
- Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Hail (relatively high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- Wildfires (relatively high): Wildfire risk can mean planned shutoffs and smoke. A battery charged by solar gives quiet backup, and fueled generators need extra care on dry days and clear space around them.
