Compare Katy Electricity Rates, Plans and Providers

Katy, Texas, offers residents hundreds of energy plans, dozens of light companies and a wide range of electricity rates to choose from. 

According to the U.S. Energy Information Association (EIA), the Texas statewide average electricity rate is 15.60 cents per kilowatt-hour (kWh). If you do your research, you may end up with a plan that charges even less than the statewide average.

Since Katy is part of the Texas deregulated energy market, the sheer number of options available can make finding a plan overwhelming and complicated. We’ve compiled some of our picks for the best energy plans and providers in Katy to help you make the best choice for your home.

Best Katy Electricity Rates

Many plans advertise the lowest possible price, but the lowest rate doesn’t always mean that your monthly bill will be affordable. Most ultra-cheap plans come saddled with bill credits, which can make your energy bills completely unpredictable. Try to avoid these gimmicks and pick a 12-month plan without bill credits to avoid any surprise costs and end up with a low-rate electricity plan in Katy.

In the table below, you’ll find some of the best electricity plans in Katy for predictable monthly energy costs.

The rates above are accurate as of 05/08/2025 at 05:51 AM for the ZIP code 77077. The rates are the same across all ZIP codes in the CenterPoint service area. Rates shown are for 1000 kWh usage.

Cheapest Electricity Rates in Katy

You can compare the cheapest electricity rates in Katy in the table below. However, you should be careful. While low electricity rates may yield monthly savings for some Texans, they can cause billing issues for others. These plans typically rely on bill credits, which don’t guarantee savings.

Bill credit plans provide a usage-based discount when your consumption reaches a certain threshold, often 1,000 kWh. If your usage falls below this — or rises beyond a maximum amount for some plans — your effective energy rate can skyrocket. We recommend considering straightforward fixed-rate plans instead. However, these plans may suit your needs. Carefully review the electricity facts label (EFL) before signing up.

How To Choose an Electricity Plan in Katy

Follow the steps below to choose the ideal energy plan for your Katy home.

Step 1: Identify Your Electricity Usage Needs

You can narrow down your options by making sure each plan is a good fit for your electricity use patterns. Check your old bills to clearly understand your average monthly consumption in kilowatt-hours. If you have a smart meter, you can also check Smart Meter Texas (SMT), which provides access to daily, monthly, and even 15-minute interval data. 

Step 2: Review Plan Details and Rates

Once you’ve determined your energy usage, you can compare energy plans in your ZIP code. This ensures you’re only seeing plans available near you. The three most common types are fixed-rate, variable-rate or prepaid plans. Other types include bill credit, time-of-use and solar buyback plans. We recommend picking a fixed-rate plan with a 12-month term for the benefit of stable pricing. These plans also allow you to avoid the complexities of bill credits or “free night” gimmicks so you get a predictable bill each month. 

Step 3: Switch To your New Provider

Pick your new plan and provider, and we can help you sign up in five minutes or less. Whether you’re enrolling online or over the phone, signing up is swift, simple and secure. We just need some basic information from you, and your new provider will handle the rest. However, you should note whether or not you’ll owe a cancellation fee for ending your current plan early.

What To Know About Electricity in Katy

Before signing up for an electricity plan in Katy, be sure you understand some of the commonly used terms or aspects of energy plans. Below are some of the common aspects to consider. 

• Rates: pay attention to your energy charge, not just the advertised price.
• Contract length: The length of your contract can impact your rates and any potential cancellation fees. 
• Discounts and promotions: Special offers like bill credits or sign-up bonuses can help you save. However, watch out for deceptive gimmicks that can cause billing headaches.
• Electric vehicle (EV) plans: If you have an EV, a plan with free or discounted charging may help you save on your energy costs.
• Early termination fees (ETFs): Fixed-rate plans typically come with ETFs, which can range from $99 to $395. Other providers charge $15 to $20 per month remaining in your contract.

Electricity Facts Label

An electricity facts label (EFL) is a standardized document that must legally accompany each energy plan. The EFL explains all of the plan’s important details, including the energy charge, utility delivery fees, base charges and possible discounts. Before purchasing a plan, make sure you read the EFL and understand what you’re paying for and what charges go into your monthly energy bill. 

Free Nights and Weekends Energy Plans

If you spend most of your days away from home, you may be the ideal customer for a free nights and weekends energy plan. These are a type of time-of-use plan and may suit a very specific customer. If you’re away from home most of the day and you use most of your electricity at night, you may be able to save with a “free” energy plan. In general, however, you should avoid time-of-use plans. This plan typically charges inflated rates during peak-demand hours to offset the “free” energy periods, leading to higher monthly bills.

When To Switch or Shop

The best time to switch energy providers is during the spring or fall, when mild weather causes demand to drop and prices to dip. Avoid shopping during summer and winter, when extreme temperatures cause rates to rise due to increased demand.

If you’re moving cities, start looking for a provider at least on month before your move-in date. Having a full 30 days to compare should ensure that you have ample time to research and decide on a plan without feeling rushed.  

How Does Deregulated Energy Work in Katy?

Even though you can pick your light company in a deregulated energy market, you cannot pick their transmission and distribution utility company (TDU). Where you live in the state determines which utility company operates in your area.

Electricity companies purchase power from generators in wholesale auctions overseen by the Electric Reliability Council of Texas (ERCOT) and the Public Utility Commission of Texas (PUCT). The prices electric companies pay during these auctions can have a direct impact on your retail energy price of electricity. While light companies sell you electricity, utility companies deliver the power to your home or business.

Which TDU serves Katy?

CenterPoint Energy is the transmission and distribution utility (TDU) that serves Katy, Texas. They don’t set the electricity rate for you but will likely charge you some sort of service fee. Their infrastructure costs are part of your overall energy bill.
