Regulated Operations [Abstract] |
Regulatory matters | Regulatory matters The operating companies within the Regulated Services Group are subject to regulation by the respective jurisdictions in which they operate. The respective Regulators have jurisdiction with respect to rate, service, accounting policies, issuance of securities, acquisitions and other matters. Except for Suralis (formerly called ESSAL), these utilities operate under cost-of-service regulation as administered by these authorities. The Company’s regulated utility operating companies are accounted for under the principles of ASC 980, Regulated Operations. Under ASC 980, regulatory assets and liabilities that would not be recorded under U.S. GAAP for non-regulated entities are recorded to the extent that they represent incurred charges or credits that are probable of being recovered from or refunded to customers through the rate setting process. At any given time, the Company can have several regulatory proceedings underway. The financial effects of these proceedings are reflected in the unaudited interim consolidated financial statements based on regulatory approval obtained to the extent that there is a financial impact during the applicable reporting period. The following regulatory proceedings were recently completed:
Utility | State or country | Regulatory proceeding type | Details
CalPeco Electric System | California | General rate review | On April 27, 2023, the California Public Utilities Commission (“CPUC”) issued a final order approving a revenue increase of $26,979. New rates became effective in June 2023 retroactive to January 2022. The retroactive impact of this final order was recorded in the second quarter of 2023.
St. Lawrence Gas | New York | General rate review | On June 22, 2023, the New York State Department of Public Services issued an Order authorizing a revenue increase of $5,249 to be implemented over three years. New rates became effective July 1, 2023.
Empire Electric | Missouri | Securitization | In February 2021, the Company's operations were impacted by extreme winter storm conditions experienced in Texas and parts of the central U.S. (“the Midwest Extreme Weather Event”). On January 19, 2022, Empire Electric filed a petition for securitization of the costs associated with the impact of the Midwest Extreme Weather Event. On March 21, 2022, Empire Electric filed a petition for securitization of the costs associated with the retirement of the Asbury generating plant. On August 18, 2022, and September 22, 2022, the Missouri Public Service Commission (“the MPSC”) issued and amended, respectively, a Report and Order authorizing Empire Electric to securitize approximately $290,383 in qualified extraordinary costs (Midwest Extreme Weather Event), energy transition costs (Asbury) and upfront financing costs associated with the proposed securitization. Empire Electric filed an appeal of the MPSC order on November 10, 2022. On August 1, 2023 the court affirmed the amount eligible for securitization of $290,383 as compared to the Company's original aggregate request of $362,420. The Company has until August 16, 2023 to move for rehearing at the Court of Appeals, and/or file a request for transfer to the Missouri Supreme Court. If the Company determines to proceed with securitization without further appeal, the Company may incur a one-time net loss of approximately $45,000.
