ISO New England has made a preliminary determination that a Capacity Scarcity Condition (CSC) is occurring in one or more Capacity Zones in the New England system at 2025-06-24 05:50:00 PM. This determination is subject to change pending the finalization of real-time reserve prices for the relevant time period, which occurs within five business days from the applicable Operating Day pursuant to Section III.2.9A(a) of the ISO New England Transmission, Markets and Service Tariff.
Pursuant to Section III.13.7.2 of the ISO New England Transmission, Markets and Services Tariff, a CSC exists in a Capacity Zone for any five-minute interval in which the Real-Time Reserve Clearing Price for that entire Capacity Zone is set based on the Reserve Constraint Penalty Factor pricing for: (i) the Minimum Total Reserve Requirement; (ii) the Ten-Minute Reserve Requirement; or (iii) the Zonal Reserve Requirement, each as described in Section III.2.7A(c) of the Tariff; provided, however, that a Capacity Scarcity Condition shall not exist if the Reserve Constraint Penalty Factor pricing results only because of resource ramping limitations that are not binding on the energy dispatch.
