Midwest ISO Commences Commercial Operations of New, LMP-Based Market
LCG, April 4, 2005--The Midwest Independent Transmission System Operator (Midwest ISO) formally began commercial operations of its new, Day-Ahead and Real-Time electricity markets on April 1, 2005. Elements of the new market design include centralized, security-constrained unit commitment; security-constrained economic dispatch; locational marginal pricing (LMP); and a market for financial transmission rights (FTRs). The Federal Energy Regulatory Commission (FERC) conditionally accepted the Midwest ISO's proposed Open Access Transmission and Energy Markets Tariff (TEMT) last August. The implementation of the new market design is another landmark following the FERC's release of Order 2000 in December 1999 and its subsequent efforts to create Regional Transmission Organizations (RTOs). The Midwest ISO's new market design is based upon the FERC's Standard Market Design (SMD) and is similar to the electricity markets of the northeast, i.e., PJM, the New York ISO and ISO New England.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 SMD, with LMP-based pricing, will generally be in use throughout the northern half of the Eastern Interconnect.
