Summit is committed to bringing natural gas to the Midcoast region but we need your help by letting us know you’re interested!

Summit Natural Gas delivers safe, clean, reliable, and efficient natural gas to residences and businesses in the Kennebec Valley area as well as Cumberland, Falmouth, and Yarmouth.

We are committed to continued growth and investment in Maine. The Midcoast area is one of the few remaining commercial centers in Maine without natural gas as an affordable, reliable, and efficient energy option. That’s why we are planning to expand our service to Belfast, Camden, Lincolnville, Northport, Rockland, Rockport, and Thomaston, with service starting at the end of 2022 in select areas throughout these communities.

  • Save money and energy with rebates of up to $3,300 for residential customers and $6,600 for commercial customers when you upgrade or replace your old heating equipment! *
  • Most service line installations are FREE! If your property is within 250 feet of our gas line, we will install your service line at little or no cost when you upgrade your primary heating system.
