Re: Supplement and Errata to Annual Report in Docket No. ER01-3001-000 Dear Ms. Bose:
Enclosed for filing in the above-referenced docket is a supplement and an errata to the New
York Independent System Operator, Inc’s (“NYISO’s”) annual report to the Federal Energy
Regulatory Commission (“Commission”) on the NYISO’s Demand Side Management programs. By
Order dated February 19, 2010, the Commission directed the NYISO to file this report for
informational purposes only.1 On January 18, 2011, the NYISO filed its annual report (“2010 Demand
Response Annual Report”). As stated in the transmittal letter and in the report, the NYISO’s analysis
of performance data for Emergency Demand Response Program and Installed Capacity Special Case
Resources events in 2010 was continuing, and the NYISO would supplement its annual report with the
results of that analysis. The NYISO submits for filing a supplement to its annual report on Demand
Side Management programs, and also an amended report which incorporates the supplemental
information.
Additionally, the NYISO submits an errata to the Annual Report. The errata is submitted in the
form of a blackline to the 2010 Demand Response Annual Report. While performing the analysis of
the event data, the NYISO identified certain data errors in the 2010 Demand Response Annual Report.
Those errors generally were driven by using Unforced Capacity instead of Installed Capacity values.
The NYISO therefore is submitting a revised annual report to correct the errors and incorporate the
supplemental report.
