PUCT Docket 58306: Oncor filed a comprehensive rate review on June 26, 2025 seeking about $834 million more in annual delivery revenue (a 12.6% increase for the residential class) to recover grid investment. A settlement with city coalitions and other parties, approved by the PUCT on April 17, 2026, cut the increase to $565 million (about $560 million net of credits) with a 9.75% ROE and a 7.8% residential increase; new delivery rates took effect about June 1, 2026, adding roughly $4.64 per month (about 3%) for a 1,000 kWh customer on a 15 cents/kWh retail plan.
