2009 State of the Market Report
Develop improved “look-ahead” capabilities in real time that would improve the commitment of quick-starting gas turbines and the management of ramp capability on slow-ramping units.
Improve the real-time operation of the system by:
Optimizing the use of the load offset to improve the Midwest ISO’s management of ramp capability in the near-term; and
Reducing the system ramp consumed by interval-to-interval changes in load by improving the STLF used by the real-time market.
Improve the performance of the spinning reserve market by:
Improving the consistency between the reliability requirement for spinning reserves and the market requirement; and
Allowing the spinning reserve penalty price to set the price in the spinning reserve market (and be reflected in energy prices) during spinning reserve shortages by not relaxing the requirement.
Evaluate the formula for the regulation penalty price to ensure that it accurately reflects the costs of committing peaking resources in the Midwest ISO.
