Installer landscape

In 2024, Missouri electricity customers averaged 3.7 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: ice storms, severe/tornado. This directory lists 170 researched installers with website generator signal (122 with a dedicated generator page, 14 with repeated signal, 34 with at least one clear mention). That is a solid market by national listing volume, ranking #23 of 50. Top city clusters in the directory: Kansas City (12), St. Louis (12), Lee's Summit (6), St Peters (6). Louis (13), Lee's Summit (6), St Peters (6).

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): None statewide (local). We do not publish fabricated statewide average install prices.

Before you call

Missouri's statewide electrical contractor license is optional under §324.920 RSMo; local licenses usually govern. There is also no statewide NEC adoption. Ask which city or county license covers your install address. Use the 170 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.
