On September 27, 2017, Central Maine Power Company (CMP) submitted permit applications with the Maine Department of Environmental Protection (MDEP) for construction of the New England Clean Energy Connect (NECEC), an electric transmission line from the border with Quebec in Beattie Township to a new converter station in Lewiston. The project also includes several upgrades to CMP’s existing electrical transmission network between Lewiston and Pownal, Windsor and Wiscasset and in Cumberland. Approximately 73% of the 147-mile transmission line will be built within CMP’s existing transmission corridor. The remainder of the line will be built in an undeveloped corridor owned by CMP through working forestland in western Somerset and Franklin counties. The NECEC project will be capable of delivering up to 1,200 megawatts of renewable energy to the New England power grid. CMP submitted the NECEC project in response to a Request for Proposals issued by Massachusetts as part of its initiative to reduce greenhouse gas emissions.  Information will be added to this page as materials relating to this project become available. Information relating to this project and the Land Use Planning Commission process is available on their website:

The application was accepted as complete for processing by MDEP on October 13, 2017.  The applications will now be examined to determine whether a license can be issued for the proposed work.  For more information or to provide questions or comments, please contact Jim Beyer at 207-941-4570.
