Utility rules and programs for League City
CenterPoint and TNMP serve Galveston County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| CenterPoint Energy | wires company (you choose your plan) | CenterPoint delivers power and does not buy it; it says it offers no net metering, so what exported power earns comes from your retail electric provider (some offer buy-back plans). Your installer files the interconnection; you cannot switch on before CenterPoint gives permission to operate. |
| Texas-New Mexico Power | wires company (you choose your plan) | TNMP delivers power; as elsewhere in the choice area, your retail electric provider decides what exported power earns. Ask TNMP for its current interconnection steps; we have not verified them. |
Program details are from each utility’s own pages (read October 2026). See the Texas incentives table for statewide credits and a status for every program.

Is solar worth it in League City?
The sun is strong (about 1,360 kWh a year per kW, our estimate). Texas has no statewide net metering, so what exported power earns depends on your utility or retail electric provider; solar pays most when sized to what you use at home or paired with a battery. See the Texas incentives for the property-tax exemption.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Texas has no state income tax credit for solar; the property-tax exemption (Tax Code 11.27) for the value solar adds to your home is separate.
