Generator start and notification rules will be implemented in eMKT beginning Sept. 26, PJM told the Market Implementation Committee last week. The Operating Committee last week endorsed related changes to Manual 14D: Generator Operational Requirements.
Reason for change: The changes were approved in 2012, following a January 2011 problem statement by PJM and the Market Monitor that noted there were no rules governing unit start and notification times. This made scheduling more difficult for PJM staff, left units unavailable for lengthy periods and permitted the exercise of market power, officials said.
Impact:
- During the Peak Period (Jan., Feb., June, July and Aug.) the notification plus startup time must not exceed six days. Units will be in forced outage status until they can operate within the six-day limit.
- During Off Peak months (March, April, May, Sept., Oct., Nov. and Dec.) units may offer extended notification times that accurately reflect the physical time to bring the unit to the beginning of the startup sequence.
- Manual 14D: Generator Operational Requirements was revised: Added applicability for individual generating units greater than 20 MVA; replaced outdated reference to NERC Guidelines with reference to NERC Reliability Standards; Added requirement for generators operating or scheduled to operate for PJM to notify PJM prior to attempting a restart following a trip or failure to start.
More information: Members can review a summary of the changes in the eMKT Enhancements section and test the changes in the “sandbox” environment prior to implementation.
