Common Wholesale Power Market Envisioned Between Midwest-ISO and PJM

LCG, Jan. 22, 2002--In a "Letter of Intent," the Midwest Independent Transmission System Operator, Inc. (MISO) and Pennsylvania-Maryland-Jersey Interconnection outlined plans yesterday to form a unified wholesale market composed of producers and consumers from the two organizations.

The objectives described in the letter were the focus of discussions last week in which officials and representatives of MISO and PJM participated. The territory encompassed by the single market would include all of part of 27 Midwestern and mid-Atlantic states, the District of Columbia and Manitoba, the Canadian province.

Phillip G. Harris, PJM president and chief executive officer, said, "This Letter of Intent reflects PJM and MISO's commitment to develop a single, robust energy market that meets the needs of all customers and stakeholders in the combined region." MISO's president and chief executive officer, James P. Torgerson, said, "working with PJM on a joint and common market design will allow both regions the opportunity to rapidly realize the benefits of a seamless power market."
Among the major objectives outlined in the letter are "the safe and reliable operation of the electric power grid" and the formation of a market "administered by two separate organizations with certain functions undertaken jointly and others undertaken through common processes". Additionally, the market's "information technology network architectural design will be established that will provide for growth, redundancy, security and flexibility for he future."

The two organizations plan to encourage a cooperative design process through the input of a joint committee including stakeholders from both organizations.
