Minutes of the Annual Meeting of the Power - New York Power ...

Under the NYISO market rules, generators that provide regulation service
provide such service bounded by the units’ upper and lower operating limits.
Reserves are also available only when the unit is operating within the
dispatchable portion of their operating range. Reserves and regulation services
are provided not in addition to a project’s energy capability but as one or the
other, with the NYISO ultimately making the choice as to which service is to be
provided. Twice a year each plant must do a 4-hour DMNC test verifying its
capability given the expected flows available from the Niagara River. But these
4-hour tests do not reflect the firm capacity available to be marketed on a firm
basis.
Recommendation:
Because there is no basis to accept customer claims that the cost-based credit
should be increased, Staff does not recommend any adjustments to this element
of the CoS.
