Installer landscape

Montana (Northern Rockies) is a mixed standby market. Fuel mix is split: utility gas 49.9%, electric 28.4%, propane 13.7% (ACS 2024). Metro jobs often look like natural-gas installs; rural counties more often need propane. In 2024, Montana electricity customers averaged 5.9 hours without power (near the 10.2-hour U.S. average; EIA Electric Power Annual Table 11.3). Dominant drivers in this research pass: winter storms, wind. This directory lists 68 researched installers with website generator signal (38 with a dedicated generator page, 4 with repeated signal, 26 with at least one clear mention). That is a moderate market by national listing volume, ranking #38 of 50. Top city clusters in the directory: Kalispell (9), Missoula (6), Bozeman (4), Belgrade (4).

Fuel, codes, and cost context

Quotes diverge with fuel path: gas-line work in town, tank packages outside it. Compare itemized scopes, not headline brand prices. NEC edition in effect in this research pass (verified as of August 2026): 2020 + MT amend.. We do not publish fabricated statewide average install prices.

Before you call

Confirm electrical (and gas/propane, if used) credentials with the local AHJ; statewide licensing scope for residential standby work was not fully verified in this research pass. Ask who pulls the electrical and fuel permits, how they size the unit, and how warranty service works after install. Use the 68 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.
