NPRR321  Allow Change to Energy Offer Curve MW Amounts in the Adjustment Period (formerly "Allow Change to Energy Offer Curve MW Amounts in the Adjustment Period for Qualifying Facilities")

Approved sponsor Calpine posted 2011-02-10 ercot.com
ReasonMarket experience thus far has shown that for Resources that do not desire to be price takers on Output Schedules, the Energy Offer Curve submitted and struck in the Day-Ahead Market (DAM) may become unrealistic in Real-Time. This NPRR would allow a Resource with an Energy Offer Curve to change the MW amounts for all the price-quantity pairs to adjust for changes in physical facility capabilities and market conditions which occur in Real Time. This allows more efficient pricing to the market due to the Resource owner’s ability to more closely optimize the pricing of energy based on actual conditions affecting the Resource, such as ambient temperature and quantities of Ancillary Service products that were awarded to the Resource in the DAM.
