Nysrc Sets 16.5% Installed Reserve Margin For Upcoming Year, Will Seek Ferc Approval

摘要

A decline in generating unit availability and other factors have prompted the New York State Reliability Council to approve a 16.5% installed reserve margin (IRM) for the 2009-10 capability year, up from the current 15% reserve. NYSRC said it will seek approval from the commission, with an effective date that provides New York Independent System Operator sufficient time to use the new reserve margin in its installed capacity auction slated for March.rnThe IRM determination was based on a comprehensive study of capacity and load, and it means that load-serving entities in the New York control area must purchase installed capacity totaling at least 116.5% of their projected peak load. The capability year begins May 1.rnAlthough the results of a reliability study pointed to a 16.2% IRM under a base-case set of assumptions, the additional consideration of "sensitivity study" results and other relevant factors led the council to set the margin at 16.5%. This will provide adequate assurance" that the New York control area meets applicable resource adequacy reliability criteria, the council said.
