Generator Installation in Denver
Denver generator installers serve the full Front Range corridor — from The Highlands and Cherry Creek in the city to Highlands Ranch, Parker, Castle Rock, Littleton, and Centennial in the suburbs. Generac and Kohler natural gas standby generators are the top choice given Denver's extensive gas infrastructure. Most installations require an Xcel Energy coordination for gas service and a City of Denver electrical permit. Propane systems are common in foothill communities like Evergreen, Morrison, and Conifer where natural gas is unavailable.

Generator Installation FAQs — Denver
How much does generator installation cost in Denver CO?
Generator installation in Denver CO costs between $4,000 and $14,000. Most whole-home Generac or Kohler standby systems run $7,000–$11,000 fully installed including the automatic transfer switch, permits, and gas line work. Portable hookup installations cost less, typically $1,500–$3,500.
Do Denver generator installers serve the foothills and mountain communities?
Yes. Most Denver-area contractors serve the full Front Range and foothill communities including Evergreen, Morrison, Conifer, Golden, Lakewood, and Boulder. Propane standby generators are common in foothill areas without natural gas service. Expect slightly higher labor costs for mountain installations.
What permits are required for generator installation in Denver?
Denver requires an electrical permit for permanent standby generator installations. Xcel Energy coordination is also required for gas line tie-ins. Your licensed contractor handles both. Budget 2–4 weeks for permit and utility coordination before your install date.
What size generator do I need for a Denver home?
Most Denver-area single-family homes need a 16–22 kW standby generator to run heat, refrigerator, lights, and essential circuits. Homes with electric heat or EV chargers may need 26–30 kW. A licensed installer performs a load calculation to determine exact requirements.
What fuel type is best for Denver generator installation?
Natural gas is the most popular choice in the Denver metro because of the extensive Xcel Energy gas distribution network. It runs indefinitely during outages with no fuel storage needed. Propane is the standard choice in foothill and mountain communities outside the gas service area.
