New England wholesale market costs were significantly lower in the spring of 2023 compared to spring 2022 and 2021, the ISO-NE Internal Market Monitor told the Markets Committee.

ISO-NE violated its tariff in its handling of construction delays at a Boston-area generating plant, FERC said, slapping the RTO with a $500,000 fine.

The NEPOOL Markets Committee considered changes to ISO-NE's retirement and financial assurance rules.
