Access documentation on the development of New England’s Installed Capacity Requirement (ICR), including calculation methodology, results, and detailed assumptions. 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 for satisfying the region’s peak demand forecast while maintaining required operating reserves.
ICR is calculated as part of the Forward Capacity Market (FCM) and used as an input into the Forward Capacity Auction (FCA) for each Capacity Commitment Period (CCP). In addition, ISO New England calculates other requirements for New England and Capacity Zones. These requirements, along with ICR, are considered the ICR values:
ICR values are recalculated each year for the Forward Capacity Auction and Annual Reconfiguration Auctions (ARAs) with updated assumptions to reflect the most recent system conditions for each CCP.
ISO New England develops the ICR values 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. ISO New England files the ICR values with the Federal Energy Regulatory Commission.
