45 F.4th 162
D.C. Cir.2022Background
- In 1998 FERC approved the merger of Louisville Gas & Electric and Kentucky Utilities, conditioning approval on the merged entity joining MISO to eliminate "pancaked" (duplicative) transmission charges and preserve wholesale competition.
- In 2006 Louisville Utilities sought to withdraw from MISO; FERC approved withdrawal only after Louisville Utilities agreed via Schedule 402 to "depancake" (refund or waive) certain MISO/Louisville duplicate charges for identified municipal and wholesale customers.
- Municipal customers (including Energy Agency and P&P) relied on Schedule 402 in making long‑term investments and contracts (notably investments in Prairie State and hydropower interests, and transmission reservations).
- In 2018 Louisville Utilities asked FERC to end its depancaking obligations. In 2019 FERC authorized ending depancaking based solely on its finding that sufficient competition would remain, but created a time‑limited transition mechanism to protect some customers’ reliance interests; subsequent rehearing orders adjusted the scope and duration of protections (e.g., 10‑year cap for Prairie State-related depancaking, inclusion of certain MISO fees).
- Municipal customers and Louisville Utilities petitioned for review. The D.C. Circuit upheld FERC’s competitive‑effects findings as supported by substantial evidence but vacated FERC’s decision to end depancaking because FERC arbitrarily ignored the quantitative effect of pancaking on customer rates; the court largely sustained FERC’s reliance‑remedy design but found two aspects insufficiently explained (hydropower protection until 2057 and exclusion/limitation of a transmission reservation).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether FERC had substantial evidence that ending depancaking would leave sufficient competition | Municipal Customers: record does not show real post‑pancaking competition; offers were conditioned on depancaking and peak markets remain thin | FERC/Louisville Utilities: empirical reports and expert forecasts show many competitive suppliers and small price differences (within 5%) even with pancaking | Upheld — substantial evidence supports FERC’s competition finding and predictive market judgment |
| Whether FERC permissibly ignored rate impacts in its Section 203(b) supplemental‑order analysis | Municipal Customers: rate increases are certain and material; rates are a core public‑interest factor FERC must consider | FERC: merger condition addressed competition so only that factor need be reconsidered for modification; some precedents did not analyze rates | Reversed — FERC acted arbitrarily by refusing to consider rate effects; vacated the decision to end depancaking and remanded for rate analysis |
| Whether P&P (Prairie State investors) reasonably relied on depancaking and therefore merit transition protection | Municipal Customers/P&P: P&P finalized major investments after Schedule 402 and reasonably relied on FERC‑ordered depancaking | Louisville Utilities: P&P invested after notice of withdrawal and before Schedule 402; reliance was unreasonable | Upheld — substantial evidence supports FERC’s finding that P&P reasonably relied and is within the protected market |
| Whether scope and duration of the transition remedy were appropriate (MISO fees; Prairie State cap; hydropower term; transmission reservation) | Municipal Customers: remedy should cover all reasonable financial commitments (including full transmission reservation and long‑term hydropower obligations). Louisville Utilities: some MISO fees and indefinite obligations exceed what corresponds to Louisville charges | FERC: limited remedy to obligations corresponding to Schedule 402; depancaked certain MISO Schedules (26, 26‑A, 45); used a 10‑year proxy for Prairie State; excluded some non‑MISO contracts and limited transmission reservation coverage | Mixed — FERC’s choices on MISO Schedules and the 10‑year Prairie State cap are reasonable; however FERC failed to justify (a) protecting hydropower fees through 2057 inconsistently with its 10‑year rule and (b) its unexplained refusal to fully protect the transmission reservation; those aspects must be explained or revised on remand |
