Status: Approved
Date Posted: Aug 25, 2008
Sponsor: Texas Industrial Energy Consumers (TIEC)
Urgent: Yes
Description: This Protocol Revision Request (PRR) adjusts the Market Clearing Price of Energy (MCPE) when the deployment of NSRS occurs to provide accurate prices in Real Time through an automatic $100/MWh upward adjustment. The $100 MCPE adjustment would replace the current PRR650, Balancing Energy Price Adjustment Due to Non-Spinning Reserve Service Energy Deployment, method of removing NSRS deployments and manually re-running Scheduling, Pricing, and Dispatching (SPD). The $100 adjustment is based on the average MCPE adjustment during NSRS deployments since 01/01/07.
Reason: After-the-fact price adjustments resulting from PRR650 prevent price-responsive loads from reacting to prices in Real Time.
