Oncor's rate schedules are official tariff documents filed with the state utility commission that detail the exact rates, charges, and terms for each service class. These documents specify base energy rates, demand charges, customer charges, fuel adjustment formulas, and all applicable fees. Rate schedules are public documents available on Oncor's website.
Oncor's residential rate schedules typically include a standard flat or tiered rate, time-of-use options, and special rates for electric heating, solar customers, or EV owners. Each schedule specifies the monthly customer charge, energy rates by tier or time period, and any applicable minimum bills or demand charges.
Business customers have different rate schedules based on their size and usage characteristics. Small commercial rates are similar to residential but may include demand charges. Medium and large commercial/industrial rates have more complex structures with demand charges, power factor adjustments, and interruptible service options.
Rate schedule documents can be complex. Key sections to focus on: the applicability section (who qualifies), the rate section (per-kWh and per-kW charges), the billing section (how charges are calculated), and special conditions (minimum bills, contract terms). If you need help interpreting Oncor's rate schedules, contact their business office or use our bill analysis tool.
