Louisiana Public Service Commission v. Federal Energy Regulatory Commission, No. 20-1024 (D.C. Cir. 2021)Annotate this Case
Entergy, a public utility holding company, owns five operating companies that sell electricity in four states, including Louisiana. The companies have been governed by an agreement requiring them to act as a “single economic unit” and requiring “rough equalization” of their production costs. In 2005, the Federal Energy Regulatory Commission (FERC) determined that the production costs were not roughly equal and imposed a “bandwidth remedy”: Whenever the yearly production costs of an individual operating company deviated from the average by more than 11%, companies with lower costs were required to pay companies with higher costs as necessary to bring all five companies within that range. Entergy filed a tariff establishing a formula to calculate production costs subject to the bandwidth remedy, which FERC largely accepted.
Utilities often spread their recovery of large, non-recurring costs by creating a regulatory asset, a type of credit. The company then amortizes the asset in later years, creating debits chargeable to customers. Historically, the Entergy companies recorded regulatory assets and their related amortization expenses in FERC accounts not referenced in the bandwidth formula; this effectively accounted for deferred production costs when they were incurred, rather than when the related amortization expenses were recorded. FERC rejected that approach and excluded purchased-power costs that a Louisiana affiliate incurred in 2005 and amortized in 2008 and 2009.
The D.C. Circuit denied the Louisiana Public Service Commission’s petition for review. The Federal Power Act requires electric utilities to charge “just and reasonable” rates. 16 U.S.C. 824d(a). If FERC finds a rate unreasonable, it may establish a just and reasonable rate; FERC may reallocate production costs under the Entergy system agreement, including by ensuring compliance with the bandwidth remedy.
