PJM Interconnection is a regional transmission organization (RTO) that coordinates the movement of wholesale electricity in 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. In 1997, PJM became the nation’s first fully functioning independent system operator. The Federal Energy Regulatory Commission (FERC) encouraged the formation of regional transmission organizations (RTOs) to operate the transmission system in multi-state areas and to advance the development of competitive wholesale power markets. PJM became the nation’s first fully functioning RTO in 2001.

  • Acting as a neutral, independent party, PJM operates a competitive wholesale electricity market and manages the high-voltage electricity grid to ensure reliability for more than 60 million people.
  • PJM’s long-term regional planning process provides a broad, interstate perspective that identifies the most effective and cost-efficient improvements to the grid to ensure reliability and economic benefits on a system wide basis.
  • An independent Board oversees PJM’s activities. Effective governance and a collaborative stakeholder process help PJM achieve its vision: “To be the electric industry leader – today and tomorrow – in reliable operations, efficient wholesale markets, and infrastructure development.”
