Katy Electricity Rates
Katy has transformed from a small railroad town west of Houston into one of the most sought-after suburbs in Texas — and every household gets to choose its own electricity provider. CenterPoint Energy delivers the power through the same lines, but you decide which retail provider charges you and at what rate. With master-planned communities like Cinco Ranch, Cross Creek Ranch, and Elyson driving steady growth, the competition for Katy customers keeps rates sharp.

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.
