    Maine law states that entities must be licensed by the Maine Public Utilities Commission (MPUC) before marketing or selling electricity. There are over 110 licensed companies within the state of Maine coming for all backgrounds of generation i.e. hydro, natural gas, wind. Companies such as Central Maine Power dominate such production and distribution while there are countless other smaller facilities. Maine's largest generator of hydro-electricity is Harris Dam(Sarah Stevens Colby 09, ES398 Dam Project) produces over 85.9 megawatts. Other sites of interest are Wyman Dam on the Kennebec and the Penobscot Mills on the West Branch of the Penobscot both having the capacity to produce over 70,000 KW.

    Within Canada 95% of all hydropower plants fall under the regulation of the Canadian Hydro power Association (CHA). Of the 17 companies represented for generation Hydro-Quebec is the most influential in regards to Maine. The company is responsible of distributing power supply for the Quebec market. To meet Quebec's electric demand, Hydro-Quebec Distribution (HQD) blocks off 165 TWh of energy. To meet demand in excess of these 165 TWh, HQD must reach out to other CHA members for support. The Annapolis Royal Generating Station is one of the crowning achievements of Canadian hydropower. The tidal dam can generate 18-MW, and is located on the Annapolis River in Nova Scotia. It is currently the only tidal generating source in North America. Finished 1984, Annapolis has harnessed the power of the Bay of Fundy with mixed results. Though effective at generating energy, the project has caused significant erosion on both sides of the Dam. Other energy contributors include nuclear power as well as wind. New Brunswick constructed the Point Lepreau Nuclear Generating Station in 1983. Located near the north shore of the Bay of Fundy, the facility has a total capacity of 680 MW. In 2005 it was awarded a $1.4 billion dollar contract to refurbish the plant allowing the life span to increase by 30 years. In 2007, Atomic Energy of Canada Limited (AECL) began a $2.5 million study in interest in the installation of a new 1100 MWe Advanced CANDU reactor at Point Lepreau, to supply power to New England. Quebec also has three nuclear power plants contributing to the energy grid located in and around Becancour. Wind power has also become a viable and possibly lucrative business within Canada.  With large untouched parcels of land in the north many Canadian companies are interested in introducing large-scale wind power to Canada.
