Access ISO New England’s annual report on the region’s Installed Capacity Requirement (ICR) and related materials. The ICR is a measure of the installed resources that are projected to be necessary to meet both ISO New England’s and the Northeast Power Coordination Council’s reliability standards, with respect to satisfying the peak demand forecast for New England while maintaining the required reserve capacity.
This report documents the results, methodology, and detailed assumptions used in the calculation of ICR and related values for each capability year (or capacity commitment period) prior to and as part of the Forward Capacity Market (FCM). Related values include:
- Local sourcing requirements (LSRs)
- Maximum capacity limits (MCLs)
- The Hydro-Québec Interconnection Capability Credits (HQICCs), which are a key input into the calculation of the ICR
More About the ICR Report
- The ICR and related values are key inputs in the Forward Capacity Auction (FCA).
- The ICR identifies the minimum amount of capacity required to meet New England’s resource adequacy criterion: interrupting non-interruptible load, on average, no more than once every 10 years.
- The ISO develops the ICR through a stakeholder and regulatory process with review and action by the Power Supply Planning Committee, the Reliability Committee, the Participants Committee, state regulators, and the New England States Committee on Electricity. The ISO files the ICR and related values with the Federal Energy Regulatory Commission.
- LSRs and MCLs were not calculated prior to 2010 and the implementation of the FCM.
- Early reports used the term “Objective Capability” instead of “Installed Capacity Requirement.”
