6.8.1.12, Payments for Balancing Energy Provided from Ancillary Services During the Operating Period and 6.9.5.1, Balancing Energy Clearing Price
Description:
This PRR adjusts the Market Clearing Price for Energy (MCPE) when Replacement Reserve Service (RPRS) is deployed. This PRR is intended to be similar to PRR 650, Balancing Energy Price Adjustment Due to Non-Spinning Reserve Service Energy Deployment, which removes non-spin deployments from the bid stack before calculating the MCPE.
Reason:
The balancing energy market prices are being depressed when ERCOT procures RPRS. This PRR would address this problem by removing the RPRS deployments when calculating the MCPE. One of the sources of revenue for new or existing resources is the real-time energy market that is operated by ERCOT. Each time ERCOT procures RPRS, the MCPE is depressed, which is an unintended consequence of ERCOT’s actions and was clearly not expected when the PUCT created an energy-only market.
