Before **Higginbotham, Duncan,** and **Wilson,** Circuit Judges

**. Patrick E.**  **Higginbotham** , Circuit Judge **:** The Louisiana Public Service Commission (“LPSC”) petitions this court for a writ of mandamus compelling the Federal Energy Regulatory Commission (“FERC”) to resolve several of its complaints before the agency related to a ratemaking dispute with System Energy Resources, Inc. (“SERI”), operator of the Grand Gulf Nuclear Station. We conclude that FERC has yet to provide this court with sufficient explanation for its delay despite ongoing irreparable harm to consumers.

### adjudication before the agency represents the sole pathway for retail regulators to seek changes to regulated electric ity rates. 1 

### Public utilities may file a new rate at any time under Section 205 of the Federal Power Act, 2 

### and other parties

— such as retail regulators

— may then assert that the rate is “unjust, unreasonable, unduly discriminatory or preferential ” in a Sect ion 206 complaint. 3 

### In recent years, the LPSC

— along with its counterparts in Arkansas, Mississippi, and New Orleans

— have submitted several Section 206 complaints with FERC challenging SERI’s filed rates. The LPSC sought various remedies related to adjust ment of SERI’s return on equity, depreciation rates, alleged violations of the filed rates, and alleged violations of FERC’s ratemaking and accounting requirements, among other grievances. One of the LPSC’s complaints has now stood before the agency for ne arly six years, 4 

### while two others have languished for at least four years. 5 

### FERC recently resolved a fourth complaint four years and seven months after the LPSC filed it with the agency. 6 

### The LPSC also complained that FERC had not issued a

### although FERC has now established hearing and settlement procedures in that matter

— albeit one year and eight months after filing

— providing the relief the LPSC sought in its petition. This court has jurisdiction over the LPSC’s petition to safeguard our prospective jurisdiction to review final FERC orders under the Federal Power Act

. 8 

### When federal appellate courts have jurisdiction to review agency action, “ the All Writs Act empowers those courts to issue a writ of mandamus compelling the agency to complete the action. ” 9 

### This court also has jurisdiction under § 706(1) of the Administr ative Procedure Act (“APA”) to “compel agency action unlawfully withheld or unreasonably delayed.” 10 

### Weinterpret the All Writs Act and the APA to provide separate, but closely intertwined, grounds for mandamus relief. 11

### II. In its petition, the LPSC argu es that mandamus is appropriate because Congress intended for FERC to work through Section 206 complaints more quickly, FERC has violated a statutory command by failing to do so, and FERC inaction is causing irreparable injury to consumers. FERC responds that mandamus is an extraordinary remedy ; these complaints represent just a subset of the thirteen different proceedings addressing the Entergy system ; there is no deadline

— express or implied

— for FERC action ; and a recent D.C. Circuit opinion overturned th e agency’s methodology for complaints like these, rendering the delay reasonable. We conclude that although Congress did not impose a hard and fast deadline for FERC to resolve complaints, 12 

### it certainly anticipated greater alacrity than this. Congress pa ssed the Regulatory Fairness Act (“RFA”)decades ago to push FERC to provide greater attention to Section 206 proceedings. 13 

### Congress found the statutory remedy necessary at a time when “Section 205 proceedings on average require [d] one year for resolution ,” compared with “two years on average” for Section 206 proceedings

. 14 

### The

12 See Exxon Mobil Corp. v. FERC , 571 F.3d 1208, 1218 (D.C. Cir. 2009) (“ [Section 206] does not

. . . set a deadline for action.”). T he LPSC also argues that the Federal Power Act requires FERC to issue a preliminary decision on Section 206 complaints within 60 days. The LPSC reasons that FERC must act on utilitie s’ Section 205 rate filings within 60 days, see 16 U.S.C. § 824d(d) , and that the RFA requires parity between Section 205 and Section 206 filings , s ee 16 U.S.C. § 824e. Section 206 complaints must therefore receive action within 60 days , the LPSC concludes . This line of argument fails, however, because the Federal Power Act does not require FERC to take any action on Section 205 rate filings

— utilities’ rates simply go into effect after 60 days unless FERC acts. See 16 U.S.C. § 824d(d).

### RFA requires FERC to afford Section 206 consumer complaints the same priority as utilities’ Section 205 rate filings and “otherwise act as speedily as possible” to resolve complaint s. 15 

### The RFA also requires FERC to provide an explanation when it has “failed to” conclude any Section 206 proceeding within 180 days. 16 

### FERC appears to regularly ignore this requirement, 17 

### and it has not provided any explanations to the LPSC in this case. The RFA additionally includes a 15

- month refund period following the filing of a Section206 complaint, after which payments made under unjust rates becomes unrecoverable. 18 

### The Act also required FERC to perform a study examining any resulting “change in the average time taken to resolve proceedings under [S]ection 206.” 19 

### T he RFA reflects Congress’s sentiment at the time that FERC should take action within one or two years, and the lack of an explicit deadline does not preclude a finding that FERC has delayed unreasonably in this case

. Despite the RFA’s guidance, Section 206 proceedings before FERC appear to take much l onger, costing consumers hundreds of millions of dollars and pressuring parties to settle. The remaining LPSC complaints have gone four

- to

- six years without resolution. FERC argues that a writ of mandamus might unfairly allow the LPSC to skip to the front of FERC’s queue, noting that some complaints are one or two years older than those the LPSCfiled. But in making that point, FERC concedes that some Section 206 proceedings have stretched beyond those at issue here, meaning that many

### consumers have been pa ying unjust rates

— without hope for a refund

— for more than six years. The LPSC argues that consumers are over

- paying SERI by about $4 million per month due to the activity alleged in one complaint. Another complaint alleges that consumers in Louisiana unjus tly paid a further $360 million in costs for Grand Gulf. 20 

### These estimates gain credibility from the fact that the Mississippi Public Service Commission recently settled with SERI for $235 million. 21 

### And the unrecoverable cost to consumers grows every day FERC delays in taking final action.FERC points out that it has taken preliminary action on these complaints. Indeed, an administrative law judge issued an initial decision on the remaining set of complaints in March of 2021. 22 

### But FERC then took no furth er steps toward a final decision for more than a year, and the matter still awaits resolution nearly two years later. FERC’s argument that the LPSC cannot be allowed the “jump the queue” is also unhelpful, given that the LPSC really complains about the age of that wait list rather than its position in it. FERC also points to recent judicial opinions rejecting its method for calculating utilities’ return on equity. 23 

### Yet these speedbumps

— five years apart

— do not explain proceedings lasting four

- to

- six years. And FERC runs the risk that intervening litigation will upset ongoing matters stretching over such a long time frame.

### FERC is correct that ratemaking is challenging work, 24 

### and we are fully aware of the difficulties attending the substitution of nuclear f or other power sources, with its attendant difficulties of allocating huge installation costs among electrical suppliers now looking to a new power source. 25 

### Yet Congress has duly charged FERC with this important duty, 26 

### and FERC has yet to provide this co urt with a meaningful explanation for its inability to expeditiously conclude Section 206 proceedings. FERC must convince this court that it has acted “within a reasonable time . . . to conclude [the] matter presented to it.” 27 

### In failing to do so, FERC ri sks judicial intervention to protect the rights of the parties before it and the interests of consumers.
