Best Katy Electricity Plans by Usage Level
Katy’s housing mix skews toward larger, newer homes in master-planned communities — many with 2,500–4,000+ sq ft. That means higher baseline usage than the Houston average, especially in summer when even well-insulated homes run hard against the Gulf Coast heat.

Gulf Coast Heat + Big Homes
Katy’s larger homes and Houston-area humidity create a double whammy for summer electric bills. A 3,000 sq ft Cinco Ranch home using 1,200 kWh in March can hit 2,200–2,800 kWh in July. Always compare plans at the 2,000 kWh tier if your home exceeds 2,500 sq ft.
