Other Events Colorado Natural Gas Rate Request In January 2024, Public Service Company of Colorado (PSCo), a Colorado corporation and wholly owned subsidiary of Xcel Energy Inc. filed a request with the Colorado Public Utilities Commission (CPUC) seeking an increase to retail natural gas rates of $171 million, or an approximate 9.5% increase in the average residential customer bill. The request is based on a 2023 test year, a 10.25% ROE, an equity ratio of 55% and a $4.2 billion retail rate base including projected capital additions through Dec. 31, 2023. PSCo requested a proposed effective date of Nov. 1, 2024. PSCo has proposed to defer collection of the increased rates until Feb. 15, 2025 (following expiration of the rider to recover Winter Storm Uri costs) to mitigate customer bill impacts, with revenues for the deferred period collected over a 12-month period beginning on that date. On July 11, 202 4, three intervenors filed testimony, with CPUC Staff (Staff) and the Utility Consumer Advocate (UCA) filing comprehensive testimony. Proposed modifications: (Millions of Dollars) Staff UCA PSCo Direct Testimony $ 171  $ 171  Recommended adjustments: Capital structure and other cost of capital (48) (14) ROE (40) (31) Test year adjustments (19) (17) Capital adjustments (subject to separate review) (3) (1) Depreciation expense 15  —  Other, net (4) (17) Total adjustments (99) (80) Proposed revenue change $ 72  $ 91  ROE 8.89  % 9.20  % Equity ratio 52  % 51.4  % Test Year Dec 2023 Dec 2023 Rate Base Convention 13 month average 13 month average Staff and UCA oppose the deferral of collections until Feb. 15, 2025, instead proposing Nov. 1, 2024 as the effective date for new rates. Next steps in the procedural schedule are expected to be as follows: • Rebuttal testimony: Aug. 15, 2024 • Settlement deadline: Aug. 27, 2024 • Evidentiary hearing: Sept. 4-12, 2024 • Statement of position: Sept. 26, 2024 A CPUC decision is expected in the fourth quarter of 2024.
