Katy electricity: 44 companies, CenterPoint rates and storm facts

CenterPoint Energy owns the poles, wires and meters that reach a Katy home, and its crews fix outages. The company you buy from sets your price and mails the bill.

Is Katy served by CenterPoint or Entergy?

By CenterPoint. Its annual report says the company serves nearly all of the Houston–Galveston area. Entergy Texas covers Houston’s northeast edge, on the far side of the metro, and it never showed up in our Katy ZIP lookups. Census counts only the small city of Katy, with 25,184 people. Far more people live in the four Katy ZIP areas, and most Katy mailing addresses sit outside city limits, in parts of Harris, Fort Bend and Waller counties.

You can’t pick or leave CenterPoint, and its delivery charge is the same whichever company you choose. Not sure which wires company reaches your house? Our utility finder shows where to look on a bill, and our Houston electric companies guide covers the same wires in the city.

Look at each company’s state complaint rating first. After that, enter your monthly kWh and watch every simple 12-month plan reprice for your home.

Don’t see a name you expected?

On Oct 16, 2026, 4Change Energy, Acacia Energy and Ambit Energy had no plans listed for CenterPoint’s area. Their own websites may still take sign-ups. Read our 4Change Energy, Acacia Energy or Ambit Energy review first, or browse the full list of Texas electricity companies.

Simple 12-month plans for Katy-area homes ran from 11.8¢ to 15.1¢ per kWh at 1,000 kWh on Oct 16, 2026. The cheapest works out to about $118 a month, and the middle plan to about $130. Both include CenterPoint’s delivery.

What does an average Katy home pay?

No public source tracks a Katy-only average bill. Per the EIA, a typical Texas home used 1,096 kWh a month in 2024. At that size, the cheapest simple plan comes to roughly $129, our estimate from the 1,000 and 2,000 kWh fact-label prices. See how it compares in our average Texas electric bill guide.

Already have a plan? On Oct 16, 2026, 143 of the 177 plans in CenterPoint’s area were for new customers only. Our contract-ending guide covers the end of a term, and Houston electricity rates tracks prices across CenterPoint’s wider area.

Four Katy ZIP areas hold 413,575 people, far more than the 25,184 in the city of Katy. Many of those homes are new, and a new house may need a meter before power can start.

No meter yet? Five steps for a new house

1. 1
   Look for a meter

   A brand-new house may not have one yet, and then the address may not have an ESI ID either.

2. 2
   Call CenterPoint for an ESI ID

   CenterPoint says homeowners and builders call 713-207-2222 to have one created. It is a 22-digit number for your address and meter, and it is not an account number.

3. 3
   Wait 2 business days

   Once you have the ESI ID, CenterPoint says to allow 2 business days before you contact the company you chose.

4. 4
   Pick a company and a start date

   Give the company the ESI ID and the day you want power. Our setup guide and same-day guide list cut-off times.

5. 5
   Plan for 3 to 5 business days

   If no construction is needed, CenterPoint says meters usually go in within 3 to 5 business days of the start date your company sends. If construction is needed, ask CenterPoint how long it will take.

Moving into an older home?

The home’s last bill shows its ESI ID. We found no CenterPoint page that looks one up by address, so ask the seller, the landlord or the company you pick. About 3 in 10 households in the four Katy ZIP areas rent. If your lease includes power, or your landlord bills you for it, you can’t choose a company. Our Texas apartment electricity guide explains each setup, and our no-deposit guide covers move-in costs.

Power to Choose listed CenterPoint for 15 Katy-area ZIPs on Oct 16, 2026, and no plans for three more. Test yours.

• What we know. Census files list no ZIP area for 77410, 77491 or 77492. Census says some valid ZIPs aren’t represented, and some ZIP areas are P.O. box only.
• What we couldn’t confirm. That fits P.O. box ZIPs, but we couldn’t check each one with the Postal Service. Use the ZIP printed on your street address.
• What it isn’t. We have no evidence these ZIPs are co-op areas, so don’t read a blank result as the end of your choices.

Most Katy-area homes buy over CenterPoint’s wires. A few farm-road homes west and northwest of Katy may sit on a co-op’s lines instead, and a ZIP lookup can’t tell.

Which counties does San Bernard Electric Cooperative list?

The co-op says it has about 4,100 miles of line and 34,000 meters in parts of eight counties: Austin, Colorado, Lavaca, Waller, Montgomery, Harris, Grimes and Fayette. Fort Bend County is not on that list. On its map, the shading nearest Katy runs near Pattison, Pine Island, Prairie View, Hempstead and Waller, and in a northwest corner of Harris County. The map labels Brookshire, Cypress, Katy and Richmond and shades none of them.

The map has no street grid, so we can’t say which Brookshire, Waller or Hockley streets belong to the co-op, and we won’t name any neighborhood. If you live out on farm roads west or north of Brookshire, Waller or Hockley, check your bill for the utility name or ask the co-op before you sign with a retailer. Members of a co-op or city utility can’t pick a company.

The closest weather station with full records that we found is Sugar Land Memorial Airport. It logs 112 days a year at 90°F or hotter, but only about 6 reach 100°F.

A cooling degree-day counts each degree a day’s average temperature sits above 65°F. Add them up over a year, and a bigger total means more hours of AC. Katy has far fewer 100-degree days than Dallas, yet it needs more cooling over the year. Warm nights may be part of the reason: in June and September, the Katy-side lows run 2 to 3 degrees above DFW’s.

More AC means bigger kWh, and bigger kWh means the fine print on a plan matters more. Use the 2,000 kWh button in the table above to see who is cheapest in a heavy month.

The answer depends on your usage and on what you value. Each pick below uses the state’s complaint ratings, Oct 16, 2026 fact-label prices and our scores. No company paid to be in our table, picks or scores.

Changing from a plan you already have costs nothing to begin. The steps are in how to switch electricity providers, and our Power to Choose guide explains the state’s site.

CenterPoint restores power. Your electric company can’t. Save both phone numbers before the next storm.

What did Hurricane Beryl show about storm plans?

Beryl made landfall on July 8, 2024. The PUCT’s investigation report, filed Nov 21, 2024, found that CenterPoint’s own drill that year had assumed a Category 3 storm with 2.1 million customers affected. Beryl was a Category 1 storm, with 80 mph wind and 97 mph gusts, and it affected 2.2 million CenterPoint customers. The report says Beryl’s conditions “were not markedly different” from the drill’s.

The report also says CenterPoint’s outage tracker “failed before Hurricane Beryl, so customers could not get critical information,” and that CenterPoint launched a third tracker on July 10. On timing, it says AEP Texas, Oncor and Sam Houston Electric Cooperative restored power within a week of landfall, and that Entergy, TNMP and CenterPoint finished in the second week. We found no Katy-only outage counts, because the report gives Houston-area totals. These are the PUCT’s findings, not ours. Read the steps for a long outage in our outage guide, and see whether a home battery is worth it.

Need help paying a Katy-area bill?

• Texas 211: call 2-1-1 or 877-541-7905, and a worker points you to local help.
• TDHCA’s CEAP: the state housing agency says its Comprehensive Energy Assistance Program helps low-income households with immediate energy needs. We couldn’t open a list of agencies for Harris, Fort Bend or Waller counties, so ask 2-1-1 where to apply.

Help can run out, and no program is sure to pay. Our guide to paying an electric bill in Texas lists more routes.

Each check relies on a document the company must show you or on a public record.

1. 1
   Price it at 500, 1,000 and 2,000 kWh

   A big house can reach 2,000 kWh in a hot month. Read all three prices on the fact label, not just the 1,000 kWh one.

2. 2
   Look for a bill credit

   A price that falls at 1,000 kWh and rises on both sides usually leans on a credit. The label spells out the rule.

3. 3
   Check the label’s date

   CenterPoint changed its charges on Sept 1 and Sept 30, 2026. Prefer a fact label dated Sept 30 or later.

4. 4
   Know the exit fee

   Some plans charge one flat fee, such as $100, $150 or $300. Others bill $20 for each month left. Moving with a forwarding address is exempt.

5. 5
   Know your 3 days

   Switching from another company? You can cancel for free within 3 federal business days. Starting service at a new address doesn’t get that window.

Our fact label guide walks through the fine print of any plan. Deciding between fixed and variable? Start with fixed vs. variable rates.
