A large share of the people searching for electricity in Katy aren't switching plans — they're turning the lights on in a house that didn't exist two years ago. The Katy area, spread across the meeting point of Harris, Fort Bend, and Waller counties, has been one of the busiest home-construction markets in the country, and move-in day is when most residents pick their first plan. That first pick matters: a new two-story home out here can triple its electricity use between April and August, and the plan that looked cheapest on a rate chart at 1,000 kWh is often not the one that handles that swing best. Every address in the Katy area is on CenterPoint's deregulated grid, so you choose the retail provider and CenterPoint delivers regardless.
Newer Katy-area homes are efficient per square foot but large in absolute terms — 2,500–3,500 sq ft floor plans are common in the master-planned communities — so summer usage of 1,400–1,900 kWh is routine despite modern insulation.

Typical Homes in Katy
Katy's housing identity is the master-planned community: Cinco Ranch set the pattern, and Elyson, Cane Island, Firethorne, and Jordan Ranch have carried it west and south. Most of the inventory is post-2000 two-story construction with central AC, and the newest sections come with builder-installed smart thermostats and radiant barriers. The older grid of streets around historic downtown Katy — the original rice-farming town the sprawl is named for — holds a much smaller stock of 1960s–1980s single-story homes with very different cooling profiles.
Local planning angle for Katy
Movers dominate this market. If you're closing on a home in Katy, you can enroll a plan ahead of your move-in date with a 'move-in' switch type, which avoids paying to break a lease-transferred plan later. Compare at the usage a home of your new square footage actually produces, not what your previous apartment used.
Why Katy Residents Compare Electricity Plans
Two Katy households a mile apart can have opposite plan needs: a family in a 3,200 sq ft Cinco Ranch two-story with a pool pump will clear most bill-credit thresholds even in March, while a couple in a new 1,600 sq ft cottage-series build may miss the same threshold ten months a year. The area's construction boom also means providers compete hard for move-in enrollments here, so the spread between the best and worst plan at a given usage level is worth real money.
Who Delivers Electricity in Katy
CenterPoint (your delivery utility)
CenterPoint owns and maintains the poles, wires, transformers, and meters in Katy. They handle outages and infrastructure, but they do not sell electricity plans. You choose a retail provider separately, and CenterPoint delivers the power regardless of which provider you pick.
CenterPoint's delivery charges are the same for every customer in Harris County, regardless of retail provider. TrueBill includes these charges in every estimate.

Katy homes often use significantly more electricity during summer cooling months than during the rest of the year.
That seasonal swing changes plan economics: bill credits, minimum usage fees, and usage-based pricing can behave very differently as monthly usage moves up and down.
TrueBill ranks plans using your actual usage profile whenever possible instead of relying only on the standard 1,000 kWh benchmark.

What to Check Before Picking a Plan in Katy
Some plans only apply a credit if you use, say, 1,000 kWh or more in a month. Miss the threshold and your bill can jump. Check where your usage lands in every month, not just summer.
Rates can change across usage bands, so the advertised rate may only apply at one usage level. Compare estimated cost at your expected usage, not just the 1,000 kWh benchmark.
A monthly base charge or a fee for using too little can outweigh a low per-kWh rate, especially in smaller homes and apartments.
Longer contracts lock in your rate but usually carry a cancellation fee. Check the term and the fee in the plan's EFL before you sign up.
TrueBill factors these plan structures into every estimate. Plan terms can change, so confirm details with the provider before enrolling.
