    Source: ISO New England

    ISO New England says it is responding to FERC’s June 18, 2026 show cause order by proposing new large-load operational requirements in Part II.J of the OATT, including hourly forecasts, telemetry, communications, monitoring equipment, remote disconnect capability, and a default ramp-rate limit of 20 MW/min averaged over 5 minutes. ISO-NE says these requirements are meant to address FERC’s concerns about large-load reliability impacts and will be implemented through operating procedures and tariff redlines.

    ISO-NE proposes large-load tariff and queue process under FERC show-cause order (EL26-72)

    Source: ISO New England · Sep 15, 2026

    ISO New England says its proposal is a response to FERC’s June 18, 2026 show-cause order and would add new OATT rules for large loads, including transmission service types, application and study procedures, capacity designation, redispatch, load shedding, and operational arrangements. ISO-NE defines a large load as a single-site commercial or industrial customer with gross peak demand of 50 MW or greater at a voltage level above 60 kV, and says it will accept applications on a rolling basis, assign queue positions when complete, and post a queue showing each application’s gross peak demand, county/state location, status, service type, and filing date. The presentation also says the ISO “will continue to develop the proposal and associated Tariff redlines” through the voting meeting.

    ISO-NE Massachusetts AGO proposes lower-quantity ES accreditation for CAR-SA (Conceptual Amendment)

    Source: Massachusetts Attorney General’s Office · Sep 08, 2026

    ISO-NE Markets Committee presentation from the Massachusetts Attorney General’s Office proposes a conceptual amendment to energy storage accreditation under CAR-SA, saying that “Modeling fewer ES MW than are actually participating could address the unique disadvantages of the CAR-SA “at criteria” modeling for ES.” The proposal would “Accredit ES assuming participation of ES(Q-x)” and then “apply accreditation values to full quantity,” with the AGO saying it “does not advocate for a specific value of x at this time.”

    ISO New England says it is actively collecting information on prospective large loads and will incorporate a new large-load forecast into CELT 2026, noting that “The ISO is surveying TOs quarterly to collect information on prospective large loads” and that “Survey responses will help the ISO proactively characterize and incorporate large loads into the long-term load forecast.” The same presentation says “Most prospective large loads are seeking to connect at the retail level,” while “ISO processes have limited visibility into detailed project information” and “The ISO has very limited information on operational characteristics.”
