Overall utility rate case activity was energetic in December 2022, according to preliminary data tracked by Regulatory Research Associates.

State regulatory jurisdictions recorded one of the highest levels of combined rate case filings and decisions for any month in the last five years with 39 cases, tying May 2019.

There were 11 initial filings in December 2022 — the highest level since August 2022, which saw an end-of-summer spike of 17 filings.

Decided cases were at their highest level in December 2022 compared with any other month in the last four years. Over the last five years, only December 2018 had a greater number of decisions, with a single case more.

* Rate case filings in December 2022 rose noticeably compared to November 2022, with 11 proceedings initiated in the month compared to eight in November. Initial filings and decisions peaked in December, consistent with the uptick typically observed in the final month of the year.

* Regarding rate case decisions, December was the high for 2022, with 28 decisions observed.

* Total rate case activity of 39 cases was considerably above the 2022 average of 21.75 actions per month.

* Regulators authorized 21 new returns on equity during the month, ranging from 7.85% to 10.50%. In the six initial cases filed during December 2022 that disclosed ROE figures, the utilities requested ROEs ranging from 9.44% to 10.50%.

Mergers and acquisitions activity

Alaska — The Regulatory Commission of Alaska approved the sale of AltaGas Ltd.'s Alaskan natural gas transmission, distribution and storage assets to TriSummit Utilities Inc. for $800 million.

New Jersey — The buyout of South Jersey Industries Inc., or SJI, poses multiple risks while providing inadequate to no benefit for ratepayers, according to the opinion of the New Jersey consumer advocate. While the February 2022 announced acquisition of SJI by an infrastructure investment fund has been approved by the Federal Energy Regulatory Commission and the Federal Communications Commission and cleared the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, the transaction has yet to receive the required approval by the New Jersey Board of Public Utilities. However a decision may be near. For additional details, refer to the article SJI buyout poses risks, inadequate benefits for ratepayers says consumer advocate.

Rate case initial filings

The accompanying table reveals that utilities initiated seven electric and four gas rate proceedings in December 2022. The rate changes requested in the electric cases aggregated to a net increase of approximately $1.5 billion and the gas case filings support a $240.6 million hike.

In the electric cases where the companies seek a new authorized return on equity, the utilities requested ROEs ranging from 10.25% to 10.50%. Requested ROEs in gas cases ranged from 9.44% to 10.30%.

Resolved rate cases

Twenty-eight rate proceedings — 17 electric and 11 gas — were resolved during the month, as depicted in the accompanying chart. The rate changes authorized in the electric cases aggregate to an increase of $2.08 billion while the gas cases totaled $288.6 million.

In four limited-issue proceedings, the rate increase reflected a previously approved equity return. In the decisions where new ROEs were specified, the companies were authorized equity returns ranging from 7.85% to 10.50%, with the lowest ROE in the range awarded to Ameren Corp. subsidiary Ameren Illinois. The utility with the highest awarded ROE of 10.50% was Georgia Power, a subsidiary of Southern Co.

Significant rate case-related activity

Michigan — On Dec. 16, 2022, DTE Electric Co., or DTE-E, filed for a rehearing of a Nov. 18, 2022, Michigan Public Service Commission rate case order that authorized a significant revenue reduction from the company's request based on a lower electric sales forecast. DTE-E requested the commission reconsider the administrative law judge's sales forecast, which it alleges was made "in error and is inconsistent with the Commission's acceptance of the same approach in other cases and with respect to other customer classes." DTE-E testified that the consequences of the decision reduced its rates by more than $100 million.

Minnesota — On Dec. 7, 2022, the Minnesota Public Utilities Commission voted to allow Minnesota Energy Resources Corp. an interim increase in gas base rates of almost $37 million as its recently filed rate case, Docket No. G-011/GR-22-504, proceeds.

Ohio — AES subsidiary The Dayton Power and Light Co.'s pending electric rate case has concluded; however, the Public Utilities Commission of Ohio issued a final order Dec. 14, 2022, which requires that the utility implement a new electric security plan prior to the introduction of new rates. The utility may not be able to raise rates until July 2023. The issue stems from a provision in the company's existing ESP framework that requires the company's base rates to remain frozen, which was a contentious matter in the rate case.

Significant non-rate case activity

California — On Dec. 22, 2022, California Public Utilities Commission staff proposed a framework for the strategic retirement of the natural gas distribution systems that serve more than 11 million customers across the state.

In an unrelated matter, on Dec. 1, 2022, the PUC directed PG&E Corp. subsidiary Pacific Gas and Electric Co. to take all necessary actions to keep the 2,240-MW Diablo Canyon nuclear plant running until 2030, implementing a state law that halted the plant's decommissioning process. The commission's move also directed and authorized the utility subsidiary to establish two new cost-tracking accounts to record costs associated with extended operations at Diablo Canyon.

Iowa — An application for advance ratemaking principles filed by Alliant Energy Corp. subsidiary Interstate Power & Light Co. — initially denied Nov. 9, 2022, by the Iowa Utilities Board — was reopened by the board Dec. 29, 2022. The board agreed to accept updated testimony from the company regarding the suitability and cost efficiency of its proposed renewable energy generation projects compared with other potential generation technologies. Simultaneously, it firmly disallowed reconsideration of the company's proposed battery storage projects, which were deemed a burden on ratepayers in an environment of escalating costs.

Hearings were held Dec. 6, 2022, and Dec. 7, 2022.
