ISO-NE published initial data on how its proposed capacity market overhaul will affect resource accreditation, providing an indication of how the changes would affect capacity market revenues for different resource types.

ISO-NE proposed to reduce its performance payment rate by more than 60% in response to concerns that excessive penalties will have unintended consequences for the capacity market.

ISO-NE updated stakeholders on its methods for assessing the impacts of its proposed capacity market overhaul as it prepares to release the initial results of the long-awaited analysis.

With costs associated with ISO-NE’s new day-ahead ancillary services market far exceeding expectations, the RTO is working to fast-track changes to improve the efficiency of the market in time for next winter.

ISO-NE continued work on the second phase of its Capacity Auction Reform project, discussing modeling of the region’s gas constraints, seasonal auction design and its approach to evaluating the impacts of the auction changes.

ISO-NE outlined its planned approach for accounting for resources’ gas supply limitations in its new capacity accreditation framework at a NEPOOL Markets Committee meeting.

NEPOOL technical committees voted in favor of ISO-NE’s proposal to adopt a prompt capacity auction and update the RTO’s resource retirement process.
