How Deregulated Electricity Works in Maine
Maine deregulated its electricity market in 1997. The system operates with three components: power companies generate electricity (generation), utilities maintain high-voltage lines (transmission), and your local utility (Central Maine Power Co, Versant Power) delivers electricity to your home (distribution).
You can choose your electricity supplier from 15 competing providers. If you don't select a supplier, you automatically receive default service through your utility at a regulated rate.
