Generator Installation in Lewiston, ME
Lewiston standby work runs on propane more than gas — CMP and Versant feeders fail in every nor'easter and natural-gas service is patchy outside city limits. 14–22kW Generac and Kohler with a 500-gallon underground tank is the typical setup for a Lewiston-area mill-city home. ME contractor licensing required for the install.
Lewiston generator installs run $5,500-$14,000 for 22-26 kW Generac, Kohler, or Cummins units. ME requires a state contractor license. Permits ($95-$225). Setbacks: 5 ft from structures, 18 inches from PL.
