Why Katy Homes Are Charger-Ready
Katy’s booming master-planned communities mean nearly every home has a 200-amp electrical panel with available breaker space. This is the easiest scenario for EV charger installation:
- 200A panel = 40kW+ of capacity
- Typical Katy home uses 15–25kW of that capacity
- A 48A EV charger adds 11.5kW — fits with room to spare
- Result: Tier 1 install ($500–$1,500), no panel upgrade
Katy is served by CenterPoint Energy for electricity delivery. CenterPoint’s infrastructure supports the growing EV charging demand across the Houston metro area.
