MISO Ready to Kick Off New Electricity Markets

LCG, March 17, 2005--The Federal Energy Regulatory Commission (FERC) yesterday approved the Certificates of Operational and Organizational Readiness filed last month by the Midwest Independent Transmission System Operator (Midwest ISO). The approval carries the Midwest ISO over a critical hurdle and enables the Midwest ISO to launch its Day-Ahead and Real-Time electricity markets on April 1.

The new market design is similar to that used in northeastern markets, such as PJM, New York ISO and ISO New England. Market design elements include security-constrained unit commitment; centralized, security-constrained, economic dispatch; locational marginal pricing (LMP); and a market for financial transmission rights (FTRs).

the FERC conditionally accepted the Midwest ISO's proposed Open Access Transmission and Energy Markets Tariff (TEMT) last August, with conditions that the Midwest ISO certify its market readiness. The Midwest markets were initially scheduled to be launched on March 1, 2005; however, on January 27, the ISO announced a one-month delay, which was stated to be in response to stakeholder requests.

The Midwest ISO service territory extends from eastern Montana through the upper Midwest - including Manitoba - and south to parts of Kentucky and Missouri. With the implementation of the TEMT, the FERC's Standard Market Design, with LMP-based pricing, will generally be in use throughout the northern half of the Eastern Interconnect.
