NPRR505  ERS Weather-Sensitive Loads

This Nodal Protocol Revision Request (NPRR) establishes rules for participation in Emergency Response Service (ERS) by Loads with demand response capability that is highly sensitive to weather conditions. It creates a new category of ERS Resource — ERS Weather-Sensitive Load — and provides for their participation in ERS under the following conditions: · ERS Weather-Sensitive Loads would be eligible to participate as ERS Weather-Sensitive Loads only during ERS Time Periods that correlate to peak weather conditions (e.g., Business Hours 2 and Business Hours 3 during the June-September Standard Contract Term). · Qualified Scheduling Entities (QSEs) representing ERS Weather-Sensitive Loads would be compensated for those Resources based solely on their performance during deployment events and during unannounced testing. · Because ERCOT expects this category of Resource to consist primarily of aggregations of small customer Loads which may be subject to growth and/or churn, QSEs representing ERS Weather-Sensitive Loads would be allowed to adjust the population of their aggregations on a monthly basis during an ERS Standard Contract Term. · The NPRR establishes a structure of payment reductions for QSEs to protect against over-stated offers or projected program growth. · ERS Weather-Sensitive Loads would be subject to a maximum of eight deployment events of up to three hours per event during an ERS Contract Period. In addition, ERS Weather-Sensitive Loads are subject to up to eight ERCOT-administered unannounced tests per ERS Standard Contract Term.
