The Ninth Circuit granted CPUC's petition for review of FERC's determination that PG&E was eligible for an incentive adder for remaining a member of the California Independent System Operator Corporation (Cal-ISO) when state law prevented PG&E's departure without authorization. The panel held that FERC's determination that PG&E was entitled to incentive adders for remaining in the Cal-ISO was arbitrary and capricious, because FERC did not reasonably interpret Order 679 as justifying summary grants of adders for remaining in a transmission organization. The panel explained that, because FERC's interpretation was unreasonable, FERC's grants of adders to PG&E were an unexplained departure from longstanding policy. Furthermore, FERC created a generic adder in violation of the order. View "CPUC V. FERC" on Justia Law
