  1. March 5, 2014 - Demand Resources Working Group Robert B. Burke rburke@iso-ne.com Principal Analyst – Market Development, ISO--NE (413) 535-4356 Simultaneous RTDR and RTEG Resource Audits

  2. Background • Markets Committee referred review and development of a recommendation that would permit the use of a qualifying RTDR activation as a Seasonal DR Audit, while at the same maintaining the intent of the simultaneous RTDR and RTEG audit requirement. • Smaller working group established • Craig Markham • Greg Geller • Bob Ives • Doug Smith • Robert Burke • Have met by conference call

  3. Issues Considered • How to avoid double-counting performance in the event • RTDR interrupted demand during event may be all or partially carried on RTEG when operated • When simultaneous audit of RTEG and any co-located RTDR performed • Customers could deliberately do not curtail load for their RTDR Asset in order to inflate the performance of their RTEG Asset • If qualifying dispatch occurred in July, August or December, the simultaneous audit values would never be used in Demand Reduction calculations or the average seasonal reduction used in the shoulder months • Facilities can carry all or a large portion of their load on their emergency generators • Waste treatment facilities • Pumping stations • Hospitals

  4. Recommendation to DRWG • Simultaneous resource audits remain a requirement except when a qualifying RTDR dispatch occurs in the seasonal DR Audit Period • In the case of a qualifying RTDR dispatch: • Participant may select the qualifying dispatch as an audit for the RTDR resource • If qualified dispatch occurred prior to Seasonal DR Audit • RTEG resource audit would be performed separately • RTEG performance would be capped by non-interrupted demand from qualifying dispatch used as the RTDR audit • If qualified dispatch occurred after Seasonal DR Audit • RTDR performance could be used as a new audit value • Or perform additional RTDR simultaneous resource audit with RTEG resources (as it works today) , if qualified dispatch occurred prior to Seasonal Audit • A new audit record will be established for the RTDR and the RTEG assets

  5. Capping of RTEG Performance
