Louisiana Public Service Commission v. Federal Energy Regulatory Commission
761 F.3d 540
5th Cir.2014Background
- Entergy operates a multi-state system governed by a long-standing System Agreement that uses a formula (Service Schedule MSS-3) to equalize operating companies’ production costs via an annual "bandwidth" calculation.
- FERC adopted a bandwidth remedy (±11% band) to equalize production costs and excluded the Vidalia hydro plant as not a system resource.
- The System Agreement populates formula inputs from companies’ FERC Form 1 amounts and includes "unless" provisos referencing state retail regulator approvals or FERC jurisdiction for certain depreciation/decommissioning inputs.
- Disputes arose over (1) whether state-approved depreciation inputs can be challenged in annual bandwidth implementation proceedings or only via Section 205/206 filings, and (2) Entergy’s accounting "reversal" of a Vidalia capital transaction reflected in compliance filings.
- FERC initially suggested inputs could be litigated in bandwidth proceedings, later reversed and held that challenges to the formula or to state-approved depreciation inputs must proceed by Section 205/206; annual proceedings are for implementation-conformity issues.
- The Louisiana Public Service Commission (LPSC) petitioned for review of FERC orders interpreting the System Agreement’s depreciation "unless" clauses and of FERC’s approval of Entergy’s Vidalia reversal adjustments.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| (A) Interpretation of "unless" clauses (depreciation inputs) | LPSC: clauses require FERC to test and, if needed, substitute depreciation amounts in each annual bandwidth proceeding; otherwise FERC unlawfully cedes authority to states. | FERC/Entergy: clauses mean formula uses actual Form 1 amounts (including state‑approved rates); if inputs are to change, that requires a Section 205/206 filing; FERC retains oversight. | Court: FERC’s interpretation is reasonable and entitled to deference; no unlawful subdelegation; challenges to state depreciation rates are to be raised in Section 205/206, not annual bandwidth implementation. |
| (B) FERC’s change in interpretation (initial to corrected view) | LPSC: FERC reversed course without persuasive explanation; reversal is arbitrary and prejudicial (bars retroactive relief). | FERC: change was explained as based on experience with annual filings; the new explanation is reasoned; filed-rate doctrine limits retroactivity. | Court: Change was reasoned, not arbitrary; deference applies; filed-rate doctrine forecloses retroactive substitution absent proper proceeding. |
| (C) Alleged subdelegation of ratemaking authority to state regulators | LPSC: incorporation of state‑approved depreciation into the formula impermissibly subdelegates FERC’s exclusive ratemaking authority. | FERC: incorporation was reviewed/accepted when approving the formula; FERC continues to exercise oversight and may address inputs in Section 206. | Court: No unlawful subdelegation — FERC retained review power and oversight; LPSC had opportunity under Section 206 and actually pursued it but failed its burden. |
| (D) Vidalia "reversal" and notice (collateral attack/jurisdiction) | LPSC: Entergy’s reversal of Vidalia capital adjustments in compliance filings modified rates without proper Section 205 notice and FERC approval, so FERC’s later approval is defective. | FERC/Entergy: Reversal language was included and accepted in 2006/2007 compliance filings; LPSC knew (or should have known) and did not timely protest; challenge now is a collateral attack on earlier orders. | Court: Dismissed LPSC’s Vidalia claim for lack of jurisdiction as an impermissible collateral attack on prior compliance orders; substantial evidence showed LPSC was aware and had opportunities to object. |
