860 F.3d 691
D.C. Cir.2017Background
- Entergy Corporation operates five integrated utilities (Arkansas, Louisiana, Mississippi, Texas, New Orleans) governed historically by a System Agreement that pools generation and allocates costs.
- After a 2000 natural-gas price spike produced large production-cost disparities across the system, FERC adopted a "+/- 11% bandwidth" remedy to roughly equalize annual production costs among the companies and prevent undue discrimination in wholesale rates.
- The System Agreement’s bandwidth formula uses inputs including depreciation expense; states set retail depreciation rates for retail ratemaking, while FERC has its own wholesale depreciation methodology (Order No. 618).
- LPSC (Louisiana Public Service Commission) filed a § 206 complaint arguing that using state-set retail depreciation rates in the bandwidth formula produced unjust, unreasonable, and unduly discriminatory wholesale results and allowed manipulation by states.
- FERC and an ALJ considered the evidence and denied relief, finding LPSC failed to meet the burden of proof that retail depreciation rates produced unlawful discrimination or manipulation; LPSC petitioned for review, which the court denied.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether use of state retail depreciation rates in the bandwidth formula is unduly discriminatory or preferential | LPSC: Different state depreciation methods produce distortions and potential manipulation that undermine rough cost equalization | FERC: LPSC’s evidence (largely a single comparison) is insufficient to show wholesale distortion or manipulation; FERC retains oversight | Court: Affirmed FERC; plaintiff failed to meet burden of proof |
| Whether FERC departed from its precedent requiring FERC depreciation methodologies | LPSC: FERC’s refusal to require its own depreciation standards departs from precedent and is arbitrary | FERC: Bandwidth formula is a unique contractual mechanism distinct from ordinary wholesale ratemaking; precedent does not compel FERC depreciation here | Court: Affirmed FERC’s explanation as reasonable |
| Whether FERC unlawfully subdelegated its wholesale-rate authority by relying on state depreciation rates | LPSC: Allowing state-determined rates effectively delegates FERC’s decision-making authority | FERC: No subdelegation; FERC initially approved the formula and continues to exercise § 206 oversight and will act if shown unjust | Court: No unlawful subdelegation; FERC exercises and will continue to exercise review authority |
| Relief scope (including retroactivity) | LPSC: Seeks reform and retroactive relief to date back to its 2010 complaint | FERC: No basis for relief because complaint failed | Court: Denied petition; did not reach retroactivity because no entitlement to relief was shown |
