Maine Electric Power Company, Inc. (MEPCO) and Central Maine Power Company (CMP) own and operate the entire 345 kV backbone transmission network in Maine.  MEPCO owns all 345 kV lines between the New Brunswick border and Maine Yankee. This is the only interconnection between the Canadian Maritime Provinces and the North American eastern interconnection. Additionally, CMP owns and operates all other transmission in central and southern Maine, west of the Bangor area; Bangor Hydro-Electric Company (BHE) owns and operates most of the lower voltage transmission from the Bangor area to Aroostook County; and Maine Public Service Company (MPS) owns and operates the lower voltage transmission in Aroostook County. For more information about the MEPCO transmission system, see our system information.

This is not an OASIS site. This site is designed to provide information about the MEPCO transmission system, and serve as a guide for acquiring transmission service from MEPCO. Here visitors can download copies of MEPCO's Open Access Transmission Tariff, Transmission Service Agreements, and view a listing of transmission System Studies. Visitors interested in MEPCO's Standards of Conduct or in making transmission reservations on the MEPCO system must do so on MEPCO's OASIS.
