Stakeholders endorsed rule changes last week to clarify that generation owners providing Tier 2 synchronized reserves will be measured in the aggregate when PJM evaluates their performance under a new penalty structure. The Federal Energy Regulatory Commission approved the new penalties effective Jan. 1 (ER14-297).

Manual 11: Energy and Ancillary Services Market Operations already included a business rule that allows resource providers to aggregate in order to use an over-responding resource to offset the deficiency of an under-responding resource, Suzanne Coyne of PJM told the Market Implementation Committee.

The MIC voted to add new language to the Tariff, Operating Agreement and Manual 28: Operating Agreement Accounting to reflect this rule.
