Generator Installation in Brunswick, Maine

Brunswick sits on the same Central Maine Power network that went dark in the October 2017 windstorm, when more than 400,000 Maine customers lost power, and again in the March 2024 ice storm, which knocked out about 200,000 CMP customers. Wind off Casco Bay, heavy wet snow and ice on roadside trees are the usual culprits, and the peninsulas south of town, Mere Point and the Maquoit Bay shore, sit at the end of long wooded lines. Most of in-town Brunswick is on the Brunswick and Topsham Water District, but homes beyond the mains rely on well pumps, and many cellars near the water rely on sump pumps that stop the moment the lights do.

A whole-home standby generator starts on its own and switches the house over through an automatic transfer switch. Fuel matters here more than in most towns: about 21 percent of Brunswick homes already heat with utility gas, so a gas line may be at the house, while others would run the generator on propane from a tank. Sizing starts with the loads you want covered, since heat pumps, well pumps and electric water heaters change the answer. Placement has to respect clearances from windows, doors and property lines, and on waterfront lots the shoreland rules and flood zone maps shape where a pad can go. The unit also needs room for service access and a spot where snow sliding off the roof will not bury it.

A portable generator is a lower-cost route that still works well when it is connected properly. An interlock kit on the main panel and an outdoor inlet let you run chosen circuits safely, with no extension cords through windows and no risk of feeding power back onto the line while CMP crews are working on it. Goodnow Electric installs both approaches, sizes the load, pulls the Brunswick electrical permit and has the work inspected. Whichever you choose, keep a running generator outdoors and well away from the house, because carbon monoxide from a unit in a garage or breezeway is one of the most serious storm-season risks.
