About Oncor
Oncor Electric Delivery Company LLC is the largest regulated electric distribution company in Texas, serving approximately 4 million homes and businesses across 120+ counties. It operates in the ERCOT deregulated market, meaning customers choose their Retail Electric Provider (REP) while Oncor delivers the power, maintains the grid, reads meters, and restores outages.
Oncor does not sell electricity — your REP handles billing and energy supply. Oncor's delivery charges appear as pass-through items on your REP bill. Oncor is a subsidiary of Sempra Energy and has announced a $47.5 billion capital plan for 2026–2030 to modernize the grid.
Service area
Oncor's territory stretches across much of North, Central, and West Texas — from the Dallas–Fort Worth metroplex south to Waco and west to Midland-Odessa. It also covers cities like Tyler, Killeen, Temple, Denton, and McKinney.
