Doug SmithMANAGER OF DEMAND RESOURCE ADMINISTRATION

Active Resource Audit Results

Passive Resource Performance

December 2012 and January 2013

Winter Performance Update for Demand Resources

Presentation Notes• For comparability, All performance is reported in DRV and all CSO is

reported as Net CSO, which is a non-grossed up value (typically CSO/1.08 except for multi-year obligations incurred in FCA1 and 2.)

• In the rare cases of multiple audits for a resource, highest performance was used. The impact from this is trivial.

• MW values and % data are rounded.

• Performance from the RTDR Dispatch on 1/28/13 covered in May DRWG – see http://www.iso-ne.com/committees/comm_wkgrps/mrkts_comm/dr_wkgrp/mtrls/2013/may12013/a04_rtdr_performance_on_1_28_2013.ppt.
