Utility rules and programs for League City
CenterPoint and TNMP serve Galveston County, so which rules apply depends on your address.
| Utility | Type | Battery and related programs |
|---|---|---|
| CenterPoint Energy | wires company (you choose your plan) | CenterPoint’s solar program page lists an incentive of $135 per kW (cap 15 kW) for existing homes in its Houston territory; that page is not recently updated, so ask before you count on it. |

What to plan for in League City
- Cold waves (very high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
- Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Hurricanes (relatively high): Hurricanes can mean a week without power. A standby generator on natural gas or propane, or a battery with solar, beats a stack of gas cans; check flood height before you site equipment.
