ISO-NE kicked off NEPOOL discussions for the second phase of its capacity auction reform project, beginning long-awaited talks on accreditation and seasonal capacity auction changes.

MISO said a yearslong software error caused it to clear more capacity than intended in past capacity auctions and which has resulted in an approximate $280 million impact to market participants in this year’s auction.

The New England wholesale electricity markets performed competitively in 2024, while decreased imports and higher emissions compliance rates increased overall market costs, the ISO-NE Internal Market Monitor told the NEPOOL Participants Committee.

ISO-NE said it is open to capping the balancing ratio used to calculate Pay-for-Performance payments to prevent capacity resources from being required to provide more power than their capacity supply obligations.

MISO is poised to close the door on summer with an almost 122-GW peak while issuing several capacity advisories for MISO South.
