SHORT DESCRIPTION: Implementation Details for NPRRs 1058, 1131, and OBDRR 040
INTENDED AUDIENCE: All Market Participants
DAYS AFFECTED: August 23, 2024
LONG DESCRIPTION: On August 23, 2024, Protocol language associated with Nodal Protocol Revision Request (NPRR) 1058, Resource Offer Modernization, NPRR 1131, Controllable Load Participation in Non-Spin, and Other Binding Document Revision Request (OBDRR) 040, ORDC Changes Related to NPRR 1131, Controllable Load Participation in Non-Spin, will be implemented.
NPRR1058 allows all Resources to update their energy bids and offers within the Operating Period in Real-Time. Paragraph (4) of Protocol Section 4.4.9.3, Energy Offer Curve Cost Caps, requires a Qualified Scheduling Entity (QSE) to submit a reason for the update if the market submission is submitted within the Operating Period (i.e., after the end of the Adjustment Period). Per NPRR1058, the submission of a reason is required for all Resource.
NPRR1131 changes Controllable Load Resource participating in Non-Spinning Reserve Service (Non-Spin) from Off-Line to On-Line Non-Spin. Consistent with On-Line treatment, this NPRR also sets a bid floor of $75/ MWh for Controllable Load Resource capacity providing Non-Spin, equivalent to the offer floor for Generation Resources providing On-Line Non-Spin and adds the requirement that if the Qualified Scheduling Entity (QSE) also assigns Responsive Reserve Service (RRS) and/or Regulation Up Service (Reg-Up) to a Controllable Load Resource that has been assigned Non-Spin, there will be a bid floor for the sum of the RRS, Reg-Up, and Non-Spin Ancillary Service Resource Responsibilities of $75/MWh.
OBDRR040 supports the implementation of NPRR 1131 by removing Controllable Load Resources providing Non-Spin schedules and Regulation Service schedules from the Operating Reserve Demand Curve (ORDC) capacity calculations. in alignment with the standing deployment under NPRR1131.
