All resources with a capacity supply obligation are required to notify ISO New England in advance of any modifications to the resource’s listed lead market participant. The modification must be made no later than 15 days before a Forward Capacity Auction. To transfer the lead market participant on an FCM resource, submit an Ask ISO case and include a confirmation email from both parties indicating agreement with the transfer and a desired effective date. The ISO will review and process the transfer.
