THIS CASEBOOK contains a selection of U. S. Court of Appeals decisions that analyze and discuss issues stemming from rate and tariff rulings of the Federal Energy Regulatory Commission. * * * The Federal Power Act, 16 U.S.C. §§ 791a et seq., charges the [Federal Energy Regulatory] Commission with regulating "the transmission of electric energy" and "the sale of electric energy at wholesale" in interstate commerce, id. § 824(b)(1). In exercising that authority, the Commission must ensure that "[a]ll rates and charges" for the "transmission or sale of electric energy subject to" its jurisdiction are "just and reasonable," and that no public utility's rates are unduly discriminatory or preferential. Id. § 824d(a), (b); see NRG Power Mktg., LLC v. Maine Pub. Utils. Comm'n, 558 U.S. 165, 167, 130 S.Ct. 693, 175 L.Ed.2d 642 (2010). * * * To that end, the Act requires every public utility to "file with the Commission" and "keep open in convenient form and place for public inspection schedules showing all rates and charges for any transmission or sale subject to the jurisdiction of the Commission." 16 U.S.C. § 824d(c). That obligation applies whether the rates and charges are set "unilaterally by tariff" or agreed upon in individual contracts between sellers and buyers. NRG Power Mktg., 558 U.S. at 171, 130 S.Ct. 693. When a public utility seeks to change its filed rate, it must "fil[e] with the Commission... new schedules stating plainly the change or changes ... and the time when the change or changes will go into effect." 16 U.S.C. § 824d(d). ESI Energy, LLC v. FERC, 892 F. 3d 321 (DC Cir. 2018). * * * The Federal Power Act's express mandate of openness, transparency, and consistency in rates prevents discrimination, promotes fair and equal access to the utilities' services, ensures the stability and predictability of rates, and reinforces the Commission's jurisdictional authority. See Maislin Indus., U.S., Inc. v. Primary Steel, Inc., 497 U.S. 116, 130-31, 110 S.Ct. 2759, 111 L.Ed.2d 94 (1990); Consol. Edison Co. of N.Y. v. FERC, 347 F.3d 964, 969 (D.C. Cir. 2003); Consol. Edison Co. of N.Y. v. FERC, 958 F.2d 429, 432 (D.C. Cir. 1992). ESI Energy, LLC v. FERC, ibid.
