ISO-NE reiterated its plans not to include in its capacity auction reform project the development of ambient temperature modeling capabilities or a new simultaneous seasonal auction clearing engine.

As ISO-NE undertakes major capacity market accreditation reforms, New England storage developers are voicing concerns that potential flaws in the RTO’s modeling methodology could discourage new investments in storage resources.

ISO-NE presented the initial scope of its work to coordinate resource capacity accreditation improvements with proposed capacity market timing changes at the NEPOOL Markets Committee summer meeting.
