  • 5.

    Improve the real-time operation of the system by:

    • a.

      Optimizing the use of the load offset to improve the Midwest ISO’s management of ramp capability in the near-term; and

    • b.

      Reducing the system ramp consumed by interval-to-interval changes in load by improving the STLF used by the real-time market.

  • 6.

    Improve the performance of the spinning reserve market by:

    • a.

      Improving the consistency between the reliability requirement for spinning reserves and the market requirement; and

    • b.

      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.

  • 7.

    Evaluate the formula for the regulation penalty price to ensure that it accurately reflects the costs of committing peaking resources in the Midwest ISO.
