Front Range weather does not ask permission. Spring blizzards, summer hailstorms, high winds rolling off the foothills, and the occasional ice storm all knock out power across the Denver metro, sometimes for hours and sometimes for days. When the grid goes down in January, a backup generator keeps your heat, your sump pump, your refrigerator, and your medical equipment running. Denver Power Electric has installed standby generators across the metro since 2009, and every installation is engineered and wired by a licensed Colorado electrician under Master Electrician Aaron Voss, License #ME.0047213.
A permanently installed whole-home standby generator is the gold standard. It sits outside like an AC condenser, runs on natural gas or propane, and starts automatically within seconds of an outage, even when you are away or asleep. There is no hauling out a portable unit in a blizzard, no extension cords, and no manual switching. We install and service units from Generac, Kohler, and Cummins, sized to either back up your entire home or cover just the essential circuits, depending on your needs and budget.
The heart of a safe install is the automatic transfer switch. It isolates your home from the grid the instant the generator takes over, which protects utility line workers and prevents dangerous backfeed, and then switches you back seamlessly when Xcel restores power. Sizing the generator and transfer switch correctly takes a real load calculation, not a guess. Many older Denver homes also need a panel upgrade to integrate a generator cleanly, and we coordinate the natural gas connection with a licensed plumber so the whole system is permitted and inspected as one project. We strongly recommend pairing any generator with whole-home surge protection, since the transfer between grid and generator is exactly when sensitive electronics are most at risk.
Backup power often fits into a larger plan for a more resilient, efficient home. Clients adding a generator are frequently also looking at EV charging and solar integration, and we design the electrical system so all of it works together rather than fighting for capacity. Every generator install requires electrical and mechanical permits and inspections in Denver and surrounding jurisdictions, which we handle from start to finish so nothing about your installation is improvised.
Generator pricing depends heavily on size, fuel source, and how much electrical work the integration requires. As a realistic range, a professionally installed whole-home standby generator in the Denver area typically runs $6,000 to $15,000 including the transfer switch, gas connection, pad, and permits. Essential-circuit setups cost less; large homes with full coverage and a panel upgrade cost more.
