NPRR505  ERS Weather-Sensitive Loads

Withdrawn sponsor ERCOT posted 2012-11-28 ercot.com
ReasonERS is procured for four-month Contract Terms and requires participating Loads to meet availability and performance requirements for a fixed capacity obligation for the entire term. This has limited the ability of weather-sensitive Loads to offer their full potential and/or to meet event or test performance requirements during periods of mild weather. Consequently, ERS in its five-year history has attracted very little participation from weather-sensitive Loads. Peak demand in the ERCOT Region, both in summer and winter, is driven by weather-sensitive Load, primarily residential and small commercial air conditioning in the summer and electric heat in winter. This NPRR is expected to make ERS more accessible for HVAC-driven Loads, in turn enhancing grid reliability by attracting more emergency demand response capacity to ERS.

Summary
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.
