ISO-NE and NEPOOL file proposal to extend Day-Ahead Energy Market submission window

On July 27, ISO New England and the New England Power Pool (NEPOOL) filed a proposal with the Federal Energy Regulatory Commission (FERC) to add 30 minutes to the submission window for the Day-Ahead Energy Market. The window, which currently closes at 10 a.m. each day, would extend to 10:30 a.m. if FERC approves the change. The ISO will still be required to clear the market and post results by 1:30 p.m. each day.

The proposed extension, which received unanimous support through the NEPOOL stakeholder process, will afford suppliers additional time to consider late-breaking information before finalizing their day-ahead offers and bids.

ISO-NE and NEPOOL have asked for the changes to become effective September 30, 2020.
