It is part of the Eastern Interconnection grid operating an electric transmission system serving all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia.
PJM, headquartered in Valley Forge, Pennsylvania, was the world's largest competitive wholesale electricity market until the development of the European Integrated Energy Market in the 2000s.[4] More than 1,000 companies are members of PJM, which serves 65 million people and has 185 gigawatts of generating capacity. With 1,436 electric power generators and 85,103 miles of transmission lines, PJM delivered 783 terawatt-hours of electricity in 2021.[5]
Started in 1927, the pool was renamed the Pennsylvania-New Jersey-Maryland Interconnection (PJM) in 1956. The organization continues to integrate additional utility transmission systems into its operations.
The Federal Energy Regulatory Commission (FERC) regulates PJM[6] and approves its open access transmission tariff for the wholesale electricity market.
