  1. Highlights of Midwest ISO:2004 State of the Market Reportand Day-2 Energy Markets Prepared by: David B. Patton, Ph.D. Independent Market Monitor Midwest ISO April 13, 2005

  2. Monthly Average Electricity and Fuel Prices Cinergy Day-Ahead Electricity Prices -- 2004

  3. Upstream-Downstream Prices and TLR Events Selected NIPSCO Flowgates

  4. TLR Events and Transactions Curtailed 2003 to 2004

  5. Disposition of Reservation Requests 2002-2003

  6. Conclusions: Day 1 vs. Day 2 Markets • The transmission reservation process and the TLR process has been implemented competently by the ISO. • However, our analysis indicates that these processes are substantially inferior to the Day 2 markets for managing congestion, utilizing available transmission capability, and maintaining reliability. • The Day 2 markets will dispatch the most effective resources to manage congestion. • Prices will more fully reflect the congestion and losses under the Day 2 markets, sending more accurate short-run and long-run economic signals. • The real-time economic redispatch (every 5 minutes) will allows transmission interfaces to be operated closer to the rated limits (e.g., to have lower transmission reservation margins and other operating offsets). • The relief available from redispatch is much more predictable and timely than relief through TLR or emergency redispatch, which should contribute to improved reliability.
