About PJM

PJM Interconnection is a regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of Delaware, Maryland, New Jersey, Ohio, Pennsylvania, Virginia, West Virginia and the District of Columbia. Acting neutrally and independently, PJM operates the world’s largest competitive wholesale electricity market and ensures the reliability of the largest centrally dispatched control area in North America. PJM’s members/customers include power generators, transmission owners, electricity distributors, power marketers and large consumers.

PJM manages a sophisticated regional planning process for generation and transmission expansion to ensure the continued reliability of the electric system. PJM serves more than 25 million people. The company dispatches more than 76,000 megawatts of generation capacity over more than 20,000 miles of transmission lines. PJM has 245 market participants and has administered more than $17 billion in energy and energy-service trades since the regional markets opened in 1997.

PJM is responsible for maintaining the integrity of the regional power grid and for managing changes and additions to the grid to accommodate new generating plants, substations and transmission lines. PJM analyzes and forecasts the future electricity needs of the region. The company ensures that growth occurs in an orderly, planned fashion and that reliability is maintained. PJM develops innovative programs, such as demand-side response initiatives, to help supply energy and keep prices competitive. PJM began the transition to an independent, neutral organization in 1993 when the PJM Interconnection Association was formed to administer the power pool. In 1997, PJM became a fully independent organization. Later that year the Federal Energy Regulatory Commission (FERC) approved PJM as the nation’s first fully functioning independent system operator (ISO). PJM became the nation’s first fully functioning RTO in 2001.


The NYISO (New York's Independent System Operator) is a not-for-profit organization formed in 1998 as part of the restructuring of New York State's electric power industry. Its mission is to ensure the reliable, safe and efficient operation of the State's major transmission system and to administer an open, competitive and nondiscriminatory wholesale market for electricity in New York State. The NYISO facilitates fair and open competition in the wholesale power market and creates an electricity commodity market in which power is purchased and sold on the basis of competitive bidding. It utilizes a bid process for electricity and transmission usage, which enables the State's utilities, and other market participants, to offer electricity at competitive prices, rather than regulated rates.

The NYISO is an outgrowth of the New York Power Pool (NYPP). Following the "Northeast Blackout of 1965", New York's eight largest electric utilities joined to create the NYPP. In order to reduce the probability of another major power interruption, the NYPP combined the eight member's knowledge and technical resources in power generation and transmission. For more than thirty years, the Power Pool coordinated the statewide interconnected transmission system, designed and operated a state-of-the-art control center and trained Pool and member system personnel. An economic dispatch program, developed by the NYPP, provided New York State electric customers with reliable power at the lowest cost available.
