As an example, consider the PJM Interconnection—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, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia, serving more than 25 million people. The company dispatches more than 143,000 megawatts of generation capacity through 350 market participants and has administered more than $28 billion in energy and energy-service trades since the regional markets opened in 1997. PJM’s wholesale electricity market is similar to a stock exchange, establishing a market price for electricity by matching supply with demand. On-line eTools makes trading easy for members/customers by enabling them to submit bids and offers and providing them with continuous real-time data. A number of the eTools—OASIS (Open Access Same-Time Information System), EES (Enhanced Energy Scheduler), eSchedules, eCapacity, eMTR, eFTR (Financial Transmission Rights), and eData—are grouped together to create eSuite, which allows authorized users to access these eTools with a single user ID and password. PJM keeps markets fair by making prices transparent through eTools [37]. The integration of this pricing information automatically into the EMCS arena is still an area being developed.
Electricity and Utility Industry

Two pools deserve mention. One is the highly successful PJM pool, the poster child for how to organize and run a pool, and the other is the California pool as operated in 2000, the poster child of what not to do. The PJM pool was the world’s first electricity power pool, formed by three utilities in 1927 to share their resources. Other utilities joined in 1956, 1965, and 1981, which led to the PJM pool covering most of Pennsylvania, New Jersey, and Maryland. Throughout this period, system operation was handled by one of the member utilities. In 1962 PJM installed an online computer to control generation in real time and in 1968 set up the Energy Management System to monitor transmission grid operations in real time. The transition to an independent neutral organization began in 1993 and was completed in 1997 with the formation of the PJM Interconnection Association, the nation’s first fully functioning ISO approved by FERC. PJM also became the nation’s first fully functioning Regional Transmission Organization (RTO) in 2001 in response to FERC Order 2000. RTOs operate transmission systems on a multistate or regional basis to encourage the development of competitive wholesale power markets. PJM Interconnection coordinates the continual buying, selling, and delivery of wholesale electricity throughout its region, balancing the needs of providers and wholesale consumers as well as monitoring market activities to ensure open, fair, and equitable access for all participants. PJM Energy Market operates much like a stock exchange, with market participants establishing a rate for electricity through a bidding process that matches supply with demand.

Baltimore Gas and Electric (BGE) is the largest gas and electricity provider in Maryland. It delivers power to 1.3 million customers in a service territory that covers 2,300 square miles, including the City of Baltimore and all or parts of 10 central Maryland counties. BGE is regulated by the Maryland Public Service Commission (MDPSC). As a result of deregulation, BGE is a transmission and distribution utility that does not own generation. It is part of the PJM Interconnection, which operates the transmission network and competitive wholesale electricity market that cover Maryland and a number of other mid-Atlantic and Midwest states. The Maryland Energy Administration (MEA), a state government office, plays a significant role in promoting ‘affordable, reliant and cleaner’ energy for the state of Maryland.
