A three-judge panel of the D.C. Circuit Court of Appeals questioned FERC over its approval of ISO-NE’s renewable exemption from the MOPR.

FERC rebuffed generators’ attempt to apply ISO-NE’s minimum offer price rule (MOPR) to 200 MW of renewable generation that were granted an exemption.

FERC has again upheld ISO-NE’s limited exemption for renewables from the RTO’s minimum offer price rule.
