Oncor Electric Delivery

Oncor does not set residential time-of-use rates because Texas operates a deregulated retail electricity market: Oncor owns and operates the wires, meters, and substations, while customers buy energy from retail electric providers (REPs). Its delivery tariff has no EV-specific rate, and any EV-specific TOU plan, including the "free nights" structures popular in Texas, is set by the REP rather than by Oncor. Drivers comparing REP offers should focus on the kWh price during the overnight window they actually charge in, not the headline rate.

Oncor's direct customer-facing EV program is the Take a Load Off Texas Retail Products program, which takes $100 off a qualifying Level 2 charger bought through its online Marketplace and shipped to the home. The discount comes off the purchase price at checkout rather than as a post-install rebate, and it is limited to one per address, so confirm the live offer on the Marketplace before buying. Oncor does not run a residential or commercial managed-charging program; its residential load management program works through smart thermostats, and its Toyota vehicle-to-grid research pilot is not open to customer enrollment.

Oncor's footprint covers more than 4.1 million homes and businesses across north, central, west, and east Texas, including most of the Dallas-Fort Worth metroplex. As a transmission and distribution utility, Oncor's role on the EV side is limited; the determinative variables for drivers in this territory are which REP they choose and what overnight rate that REP charges. Texas law also bars transmission and distribution utilities inside ERCOT from directly owning or operating public chargers, so the public charging build-out in Oncor territory is driven by retail providers, networks, and city programs rather than the utility itself.
