What “renewable” means on an Oncor bill
A plan is on this list when its EFL and Power to Choose agree that its renewable content is 100%, or, with no agreed figure on record, when its provider markets its entire residential lineup as 100% renewable. Either way the provider retires renewable energy certificates matching your usage, while the electricity on Oncor's wires is the same grid mix for every home. See renewable electricity plans in Texas.
Of the 27 plans on this list, 1 carries a usage-based bill credit and 0 a minimum-usage fee. Oncor's delivery charge adds $72.73 to every one of them at 1,000 kWh, whichever provider you choose.
