Oncor's old rates served as interim rates from Jan 1, 2026 until its new rates started June 1. The interim-rate agreement lets Oncor surcharge the difference; it filed on June 9, 2026 and the surcharge took effect Aug 1, 2026 to collect about $212 million through year-end. Retail providers pass Oncor's delivery charges to households; no residential bill impact was published.
