MARYLAND OFFICE OF PEOPLE'S COUNSEL v. FEDERAL ENERGY REGULATORY COMMISSION PJM INTERCONNECTION, L.L.C
The D.C. Circuit vacated FERC's denial of a complaint seeking to lower inflated electricity rates, ruling that the agency's reliance on a prior Third Circuit decision was legally insufficient. The court held that the Third Circuit's ruling on tariff amendments did not foreclose FERC from addressing the resulting high auction prices under its separate authority to modify unjust rates.
