ERCOT Files NPRRs to Mitigate Price Suppression During Reserve Deployments
Copyright 2011 EnergyChoiceMatters.com.
ERCOT has filed several Nodal Protocol Revision Requests aimed at mitigating price suppression during the deployment of reserve services in order to more accurately reflect the value of the service.
The NPRRs are in response to recent PUCT direction. Urgency status was requested for all of the NPRRs.
NPRR 428 will be the vehicle to implement a requirement for the Energy Offer Curve to be at or above $120/MWh for On-Line Non-Spinning Reserve (Non-Spin) capacity and at or above $180/MWh for Off-Line Non-Spin capacity.
NPRR 427 would add a requirement for the Energy Offer Curve to be set at the System-Wide Offer Cap (SWCAP) for the capacity reserved for Responsive Reserve (RRS) Service Ancillary Service Resource Responsibility and Regulation Up (Reg-Up) Ancillary Service Resource Responsibility.
