Installer landscape

Colorado (Intermountain West) is a natural gas first standby market. Heating fuel leans natural gas (66.6% of occupied homes on utility gas, ACS 2024), so many installs start with meter capacity and gas-line sizing rather than a new tank. Propane still shows up in rural counties (4.5%). In 2024, Colorado electricity customers averaged 4.3 hours without power (well below the 10.2-hour U.S. average; EIA Electric Power Annual Table 11.3). Dominant drivers in this research pass: high wind, spring snow, psps (new). This directory lists 181 researched installers with website generator signal (132 with a dedicated generator page, 13 with repeated signal, 36 with at least one clear mention). That is a solid market by national listing volume, ranking #21 of 50. Top city clusters in the directory: Colorado Springs (16), Denver (11), Fort Collins (9), Centennial (7).

Fuel, codes, and cost context

All-in price usually hinges on electrical scope, transfer equipment, and gas-line/meter work more than a tank package. NEC edition trackers need a local confirm (research note: 2026 (NFPA) / 2023 (Mike Holt) - conflict). We do not publish fabricated statewide average install prices.

Before you call

Colorado sets statewide residential noise limits by statute (55 dB(A) day / 50 dB(A) night, measured 25 feet beyond the property line). Weekly exercise cycles need a plan that respects that. NEC edition trackers conflicted as of August 2026, so confirm the edition with the State Electrical Board and your local AHJ before citing section numbers. Use the 181 researched listings below as a starting point, not an endorsement. Verify licensing, insurance, references, and recent standby work yourself.

Fuel and outage figures sourced from ACS 2024 and EIA 2024; NEC and licensing notes verified as of 2026-08-07. Not legal advice. Confirm with your AHJ.
