Oncor Files Unified Tracker Mechanism Request to Support Reliability and Continued Growth

NEWS RELEASE

Oncor Communications: 877.426.1616

DALLAS (April 23, 2026) - Today, Oncor announced the filing of its first request under the Unified Tracker Mechanism (UTM), a regulatory process that allows certain transmission and distribution investment costs to be reviewed together in a single annual proceeding. This new process, as established through recent legislation, streamlines how certain utilities recover costs associated with critical infrastructure that supports reliability, resiliency, and continued statewide growth.

If approved, Oncor estimates the request would result in an average monthly increase of approximately $3.85 over current rates for a residential customer using 1,000 kWh of electricity per month at an average retail electric price of $0.15/kWh. This reflects an approximately 2.5% increase.

This rate update reflects Oncor's capital investments in transmission and distribution infrastructure placed in service between January 1, 2025, and December 31, 2025, including costs associated with new and upgraded transmission facilities, system interconnections, and distribution assets such as poles, wires and substations, as well as related equipment needed to support customer growth and maintain reliable service. These investments, including applicable infrastructure hardening and modernization efforts, remain tied directly to capital investments, are subject to regulatory review and approval.

"Our customers and communities depend on a safe and reliable electric system, and we take seriously the responsibility to manage costs thoughtfully while maintaining that reliability," said Debbie Dennis, Senior Vice President, Chief Customer Officer and Chief HR Officer. "The UTM provides a more efficient way to review the same types of transmission and distribution investments that have traditionally been incorporated into rates over time, while continuing to support the investments needed to serve a growing Texas."

The UTM combines rate adjustments that previously occurred through multiple proceedings (such as the Distribution Cost Recovery Factor and Transmission Cost Recovery Factor) into one annual filing. This results in a clearer, more predictable regulatory process while reducing the number of adjustments customers may see during the year.

In addition to recovering recent investments, the UTM updates how costs are allocated among customer classes to better reflect current usage patterns and continued growth. This annual update benefits residential customers by reallocating to reflect growth among large commercial and industrial customers.

The filing was made with the Public Utility Commission of Texas (PUCT) in Docket No. 59249 and is subject to PUCT review and approval.
