Ramp Rate, CP Implementation at Center of OC Meeting

After a lengthy discussion, the Operating Committee Tuesday endorsed an interim solution for the performance assessment hour ramp rate.

The OC also had an extensive discussion regarding implementation of two Capacity Performance-related items – real-time values and unit-specific parameters. Mike Bryson, vice president – System Operations, provided details on what processes are available to market sellers to reflect temporary operating conditions.

Performance Assessment Hour Ramp RateMIC OC unit parameters

 With 22 objections, the committee endorsed proposed revisions to the PJM Tariff and Manual 18, related to the performance assessment hour ramp rate. The Markets and Reliability Committee and Members Committee will vote on the proposal at their March 31 meetings.

The performance assessment ramp rate is a proposal to recognize how units follow PJM dispatch instructions during performance assessment hours. The proposal allows a unit’s ramp rate to be considered in scheduled megawatts in the non-performance charge calculation during performance assessment hours.

In order to be effective for the 2016/2017 Delivery Year, which starts June 1, PJM wants to file any change with the Federal Energy Regulatory Commission by March 31, with an effective date of May 31.

Capacity Performance

PJM gave an update on the implementation of the unit-specific parameter process including adjustment request statistics and an explanation of next steps.

PJM received a number of requests from Capacity Performance resources for unit-specific parameter adjustment for delivery year 2016/2017 prior to the February 28 deadline. PJM is reviewing the requests and accompanying documentation. PJM’s intention is to answer the market seller as soon as possible – ideally five days after a conference call between PJM and the seller. The deadline for notifying market sellers is April 15.

 In addition to Bryson’s presentation on the temporary operating conditions, PJM reviewed an example of how real-time values will be handled from a settlements perspective.

Real-time values communicate a resource’s current operational capabilities. They are used when the resource cannot operate according to the unit-specific parameters (Capacity Performance and Base Capacity) or default parameter limited schedule (for non-CP resources) based on a physical limitation.

Other Actions

The OC also endorsed two additional manual changes:

  • Manual 12: Balancing Operations, regarding PJM business rules for dynamic transfers
  • Manual 01: Control Center and Data Exchange Requirements
