The Market Implementation Committee approved changes to Manuals 1 and 18 Wednesday to implement an automated process that will allow Curtailment Service Providers to provide operational data to — and receive dispatch instructions from — PJM.
The new Load Response System (eLRS) process replaces the current manual methods, which rely on email and spreadsheets.
Reason for Change: PJM needs operational data to estimate the real time energy reductions likely in response to a PJM dispatch of emergency demand response resources.
Impact: The automated data should allow PJM more accurate dispatch of Emergency DR resources and help determine those resources eligible to set the real time LMP.
CSPs will be required to contact their emergency DR resources to determine their load reduction capability (e.g., outages at the facility; reductions based on high expected prices, peak shaving or contract provisions). The updates are to be done monthly in October through May, daily in June through September and hourly when under a Max Emergency Generation Alert or Action.
The real time dispatch instructions will be used in emergency and synchronized reserve events. CSPs will have a communication link through eLRS that will poll PJM once a minute for event notifications and instructions and provide PJM acknowledgement that the instructions have been received. For companies without an information technology staff, PJM will provide a software client.
The real time dispatch system will be available in the PJM “sandbox” May 16 for testing, prior to the production deployment May 22.
