Oncor is an investor-owned utility serving about 3,545,814 homes in Texas. Here's what its rates and export rules mean for solar: for a typical customer, solar is worth it.
No statewide net metering (Texas rule).
Texas has no statewide net metering. In the deregulated ERCOT market you pick a retail electricity provider, and a few offer 'solar buyback' plans (typically 3-9 c/kWh, some match retail). Municipal utilities and co-ops set their own rules, e.g., Austin Energy's Value of Solar credit.
No statewide net metering in ERCOT competitive areas; export compensation is set by the customer's retail electric provider (some offer buyback at retail or wholesale-indexed rates, many offer none). TDU charges apply to gross imports.

EIA-861, 2025. In competitive markets, some solar is reported by retail electricity providers instead.
Oncor follows Texas's rules: Texas has no statewide net metering. In the deregulated ERCOT market you pick a retail electricity provider, and a few offer 'solar buyback' plans (typically 3-9 c/kWh, some match retail). Municipal utilities and co-ops set their own rules, e.g., Austin Energy's Value of Solar credit.
Residential customers paid an average of 17.3¢ per kWh in 2025 (EIA), about 17.9¢ adjusted to 2026. The typical home uses 1,106 kWh a month, a bill of about $198.
For a typical customer, solar is worth it: a 4.3 kW system costing about $12,530 pays back in about 12.5 years, with $16,855 net over 25 years.
Oncor did not report residential net-metered solar to EIA for 2025, likely because retail electric providers report it in competitive markets.
