Table Notes: The Part A Test uses forecast prices for the first year of the Mitigation Study Period, i.e. Capability Year 2014 for Class Year 2011.

The Part B Test uses all three years of the Mitigation Study Period, i.e. Capability Years 2014/15-2016/17 for Class Year 2011.

This posting pertains to Examined Facilities in NYC. The Services Tariff has a separate timeline for evaluating and posting information for New Capacity Zone Examined Projects. See Services Tariff Att. H Sec. 23.4.5.7.2.4.

Notes:

- For Class Year 2011, the Default Net CONE is calculated based on Capability Year 2014, the first year of the Mitigation Study Period.

- This example shows the seasonal shaping of the Demand Curve proxy unit. When applied to Examined Facilities, unit-specific values for Qi , Qw , and Qs will be utilized.

- The inflation rate is equal to the escalation factor of 1.7% in the currently-accepted ICAP Demand Curves.

- The term “Mitigation Net CONE” is currently pending before the Commission in Docket No. ER10-2371. See New York Independent System Operator, Inc.,

Resubmittal of August 12, 2010 Filing, Docket No. ER10-2371-000 (filed Aug. 24, 2010).
