Not sure if someone else posted, but in the fine print of your bill is the number for the Public Utilities Commission. In 2019 I spoke at their hearings w/CMP lawyers present. I plan to again in the very near future. Possibly contacting your town's legislative representative.

This is why we have on the fall referendum the option to vote for Pine Tree Power, which is consumer owned. Madison Electric, Kennebunk, Boothbay Harbor and other towns have their own community based company. I have friends that live in those areas and swear their bills are lower and don't have the outages like the rest of us.
