The Northeast Power Coordinating Council (NPCC) was formed January 19, 1966, as a successor to the Canada–United States Eastern Interconnection (CANUSE). It was formed in order to improve reliability of electric service. NPCC is one of six regional entities under North American Electric Reliability Corporation (NERC) authority. NERC and the regional reliability councils were formed following the Northeast Blackout of 1965. NPCC's offices are located in New York City, New York. At the time of its formation in 1966, NPCC had 22 utility systems as members. As of 2019, NPCC has 90 members.
