Summary

This Nodal Protocol Revision Request (NPRR) directs ERCOT to prepare and publish estimated Demand response data showing aggregated State Estimated Load (SEL) load points selected by ERCOT. The selection of Loads to be aggregated for the report will be based on periodically updated off-line analysis of the frequency and magnitude of reductions observed in historical State Estimator load data that is associated with market signals such as Locational Marginal Prices (LMPs), high levels of summer month ERCOT load, ERCOT-wide appeal(s) through public voluntary energy appeal, or other ERCOT actions.
