On June 13, 2025, Liberty filed a petition to adjust its base distribution rates. Utilities regulated by the DPU can file petitions to recover reasonable and prudent costs that have been incurred to provide safe and reliable service to its customers and have the opportunity to earn a fair and reasonable rate of return on prudently invested capital.
The company’s last rate case with the DPU was in 2015 (DPU 15-75).
Liberty seeks to increase its gas distribution rates to generate approximately $30 million in additional revenues. According to the Company, the net effect of the request is expected to be a 55.5 percent rate increase, on average, across all customers on a total bill basis.
The DPU will review the new proposal, filed in docket DPU 25-85, and will suspend Liberty's proposed distribution rates until May 1, 2026, to conduct its investigation.
In each base distribution rate proceeding conducted by the DPU under section 94, the DPU shall design base distribution rates using a cost-allocation method that is based on equalized rates of return for each customer class; provided, however, that if the resulting impact of employing this cost-allocation method for any 1 customer class would be more than 10 percent, the DPU shall phase in the elimination of any cross subsidies between rate classes on a revenue neutral basis phased in over a reasonable period as determined by the DPU. Section 94I
In this investigation, the DPU’s staff will review all written testimony, detailed cost data, and public comments. These documents will be filed in the docket, DPU 25-85. The DPU’s staff will also hold public and evidentiary hearings for this proceeding. The dates for those hearings will be posted once available.
