CWT California Water Service Group

(NYSE: CWT)—The California Public Utilities Commission (CPUC) has granted the request of California Water Service (Cal Water) and three other utilities to postpone their Cost of Capital applications from May 1, 2025 to May 1, 2026. The decision effectively maintains the current 10.27% return on equity (ROE) and 4.23% cost of debt for Cal Water, with a capital structure of 53.40% common equity and 46.60% long-term debt, and an authorized rate of return of 7.46%.

The CPUC also reauthorized the Water Cost of Capital Mechanism (WCCM). Among other provisions, the WCCM automatically adjusts the rate of return when the Moody’s Utilities Bond Index fluctuates between Cost of Capital applications. The ROE will remain 10.27% through Dec. 31, 2026, unless the WCCM is triggered when next measured on Sept. 30, 2025. If a change in the ROE is required, it would become effective on Jan. 1, 2026.

"We appreciate the CPUC's agreement to grant us an additional one-year extension on our Cost of Capital proceeding," said Martin A. Kropelnicki, Chairman and CEO. "There are several ongoing water utility rate cases currently before the CPUC, including our 2024 General Rate Case and Infrastructure Improvement Plan, that require the resources of staff, the utilities, and other parties to the proceeding. The extension will help manage this workload and also help reduce the frequency of rate changes for our customers.”
