PJM Interconnection

PJM Interconnection LLC (PJM) is a regional transmission organization (RTO) in the United States. 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 is the largest power grid operator in the United States, serving 67 million customers from Chicago to New Jersey. 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. More than 1,000 companies are members of PJM, which has 182 gigawatts of generating capacity. With 1,436 electric power generators and 88,333 miles (142,158 km) of transmission lines, PJM delivered over 800 terawatt-hours of electricity in 2024. Started in 1927, the pool was renamed the Pennsylvania-New Jersey-Maryland Interconnection (PJM) in 1956.

The Federal Energy Regulatory Commission (FERC) regulates PJM, and approves its open access transmission tariff for the wholesale electricity market. In 2026, PJM is anticipating future supply shortages due to expected 5% annual demand growth (compared to no growth from 2005-2020) from new data centers, combined with supply constraints from shutdowns of many generation plants for environmental or economic reasons, and the difficulty of timely permitting of new power plants.

  Understanding Energy: PJM Explained PG. 1 What is PJM? PJM Interconnection is a little-known company that operates the electric grid for a region stretching from New Jersey to North Carolina, and from Illinois to our nation’s capital. From its headquarters in suburban Philadelphia, PJM coordinates the flow of electricity from generators to local utilities across a web of high-voltage transmission lines. Local utilities distribute this power directly to consumers. In addition to managing the transmission system, PJM runs wholesale markets in which it buys electricity on behalf of utilities. These markets determine the mix of energy sources that power our homes and businesses—as well as a large portion of what we pay on our monthly bills. [...] As a limited liability company (LLC), PJM is governed by a Board of Managers and a committee of voting members numbering into the thousands. Most of PJM’s members consist of energy businesses, utilities, electricity customers and others who have an interest in the company’s operations. In theory, anyone not employed by PJM can become a member; in practice, it is only accessible to those who can pay the $5,000 annual membership fee, attend numerous monthly meetings, and assume potential legal liability. [...] Sustainable FERC Project Policies for a Clean Electric Grid Understanding Energy: PJM Explained PG. 2 In its original form, PJM provided shared services to a group of utilities in the Mid-Atlantic, helping them maintain transmission lines and repair plant outages. Starting in the late 1980s, states saw a steep rise in electricity prices as integrated utilities passed the costs of their boom-bust cycle of power plant construction to consumers. Advocates fought back against this trend, prompting some state governments to restructure their power sectors by breaking up utilities and generators into separate companies. Around the same time, new federal laws were passed that drove the creation of wholesale markets in which generators could compete to supply their electricity and thereby (at

• PJM’s Speed to Power Problem and How to Fix It - RMI

  PJM, like other RTOs, operates competitive markets where generators compete to provide grid services, such as providing energy in every moment to ensure there is a balance between supply and demand. PJM also holds a capacity auction to ensure there will be enough cost-efficient generation to meet future demand (three years after the auction) by incentivizing new generation to come online and older, higher-cost generation to retire.
