Why Massachusetts Homeowners Need Generators
Protect your family from Massachusetts's severe weather threats.
Massachusetts faces some of the most severe winter weather in the country, with nor’easters capable of dumping feet of snow and bringing hurricane-force wind gusts. Coastal communities face additional threats from storm surge and flooding. The state’s aging power infrastructure and heavy tree cover mean that even moderate storms can cause multi-day outages. Ice storms are particularly damaging, as they bring down power lines and tree branches across wide areas. Massachusetts homeowners who install generators protect their families from the state’s harsh winters and gain peace of mind during the increasingly powerful coastal storms that affect the region.
