MIC Reviews Capacity Performance Emergency Procedures

Settlement issues, real-time values and emergency procedures under Capacity Performance dominated the slate at the April 6 Markets Implementation Committee meeting.

PJM presented an overview of changes related to Capacity Performance and the performance assessment hour in the next version of the Emergency Procedures tool, including changes to the main dashboard.

Members will need to update their emergency procedure extensible markup language (XML) to access the new data from the Emergency Procedures page. The XML changes to support Capacity Performance and the performance assessment hour will go into effect on May 5.

PJM will conduct an educational session/ workshop on May 2 at its main campus to provide a detailed demonstration of how unit-specific parameters and real-time values impact offers and settlements, operator communications and settlement calculations work during a performance assessment hour.

PJM is also creating an online training module for all generation/transmission operators to be trained on the upcoming Emergency Procedure changes and the new Deploy All Resources action message. The online module will be available to operators/dispatchers through the Learning Management System by the first week of May.

In addition, PJM presented informational updates on:

  • Manual changes to define real-time values in Capacity Performance. The committee will be vote on these changes in May.
  • The settlements impact for the implementation of real-time values PJM has been working with stakeholders to develop several options; PJM presented all of the options, including its preferred one.
  • Unit-specific parameters, specifically the maximum run time parameter value implementation discussed at the Tuesday Operating Committee meeting. Market sellers who believe they cannot meet the 24-hour maximum run time value may request an adjustment by submitting the request with supporting documentation to unitspecificpls@pjm.com by Wednesday, April 20.

Stakeholder issues

The MIC defeated a proposal to continue discussion of Settlement C issues at the Market Settlement Subcommittee. The subcommittee had not been able to come to a consensus on the issue. The MIC voted to discontinue the work and close the issue with only 35.5 percent support to try again.

The committee also listened to extensive feedback on:


The MIC endorsed proposed changes to the emergency energy default customer baseline in demand response emergency energy settlement measurement and verification and it endorsed a problem statement and issue charge on spot-in transmission service for imports from the New York ISO.
