The following questions pertain to aspects of the Midwest ISO proposal that require further clarification. The Midwest ISO is requested to provide materials at the conference addressing these questions and to be prepared to discuss them. The Midwest ISO should provide its full and complete answers to all questions for the record of this proceeding in its filing of comments.

Questions To Be Discussed in the First Session

  • Provide a market power analysis for the spring and fall shoulder seasons. Present the results of the new analysis at the technical conference.
  • The definition of ancillary services sub-markets:
  • Provide the basis for how the sub-markets and reserve zones are defined and explain the differences between the two.
  • Is the IMM market power analysis for only illustrative purposes or is it intended to be relied on in this proceeding?
  • How will the potential for market power be evaluated as a result of any zonal reconfiguration?
  • Either submit separate analyses for spinning and supplemental reserves or provide an analysis demonstrating that the two products are substitutes for each other. Present the results of the analysis at the technical conference.
  • Provide historical data, separately for each ancillary services product (regulating reserves, spinning reserves and supplemental reserves), since the start of the Midwest ISO energy markets that indicates: (1) The capacity (in MWs) and number of generator resources that could provide ancillary services; and (2) the actual ancillary services provided, in MW and number of generator resources. Present the results of the analysis at the technical conference.

Questions To Be Discussed in the Second Session

  • What is the basis for the IMM's conclusion that there will be sufficient competition to ensure just and reasonable prices in those hours and locations when mitigation thresholds are not triggered?
  • Explain how reference levels are determined for suppliers in constrained areas, such as those identified in the IMM analysis. In his testimony, the IMM indicates reference levels are based on competitive offers. Please provide the basis for this assertion and explain whether all offers by suppliers in constrained areas are considered to be offers made under competitive conditions. If not, how does the IMM determine which offers are made under competitive conditions?
  • Is a backstop reference price, such as is used in the New York Independent System Operator (NYISO), appropriate for sub-markets with only one or two suppliers? Explain the reasons underlying your response.
  • Considering the market power characteristics of the Midwest ISO ancillary services market and its sub-markets, what are the pros and cons of conduct/impact mitigation compared to mitigating offers at a cost-based rate?
  • What method and criteria will the IMM use to audit and identify any supplier that withholds power in either the energy or ancillary services markets, including during periods of scarcity pricing?
  • The Midwest ISO states that variations of how it intends to mitigate its ancillary services market are being used by existing RTOs/ISOs. Explain the similarities and differences between the Midwest ISO mitigation proposal and the PJM Interconnection (PJM) and California Independent System Operator (CAISO) ancillary services markets mitigation programs.
  • The Midwest ISO states that there are no unreasonable barriers to entry that would compromise the competitiveness of the Regulating Reserve market. Prospectively, what will the Midwest ISO do to ensure a lack of barriers to entry and encourage suppliers to bid into the congested submarket areas?
