NOTICE OF RATE CHANGE REQUEST Oncor Electric Delivery Company LLC (“Oncor”) publishes this notice that on June 26, 2025, Oncor filed with the Public Utility Commission of Texas (“Commission”) its Petition and Statement of Intent to Change Rates, a copy of which is kept at Oncor’s office at 1616 Woodall Rodgers Freeway, Dallas, Texas 75202. This notice is being published pursuant to 16 Tex. Admin. Code § 22.51(a)(1). Oncor’s rate filing, based on the system-wide financial results for a 12-month test year ending on December 31, 2024, adjusted for known and measurable changes, supports a net increase in transmission and distribu- tion rates of approximately $834 million over adjusted test-year revenues, or approximately a 13% increase over adjusted test-year revenues of $6,410 million. Test-year revenues have been adjusted to normalize billing units, to remove the revenues associated with Oncor’s Energy Efficiency Cost Recovery Factor, and to increase test-year revenues to reflect Transmission Cost of Service (“TCOS”), Distribution Cost Recovery Factor (“DCRF”), and Transmission Cost Recovery Factor (“TCRF”) adjustments. TCOS revenue was adjusted to include the March 31, 2025 interim update rate at the 2024 ERCOT 4CP. DCRF revenue was adjusted to include the May 10, 2025 interim update approved in Docket No. 57707. TCRF revenue was adjusted to equal the March 1, 2025 TCRF revenue requirement re- flected on Line 2, Attachment A of Oncor’s petition approved in Docket No. 57354 and further adjusted to include the effects of the 2024 ERCOT 4CP load filed in Docket No. 57491. If approved, the increased rates will be charged to Oncor’s direct customers, all retail electric providers (“REPs”), in those portions of Oncor’s service area under the original jurisdiction of the Commission. Each such REP is potentially affected by the proposed change. Depending on the REPs’ actions, the end-use customer classes of such REPs are potentially affected by the proposed change. In addition, the result could be a change in Oncor’s transmission cost of service rates, which would impact all load serving entities in the Electric Reliability Council of Texas. Oncor has requested a July 31, 2025 effective date for its proposed rate change. Persons who wish to intervene in or comment upon these proceedings, in Docket No. 58306, Application of Oncor Electric Delivery Company LLC for Authority to Change Rates, should notify the Commission as soon as possible, as an intervention deadline will be imposed.
