Killeen, Texas electricity: Oncor wires and 64,846 competitive homes
Killeen's off-post neighborhoods are Oncor territory with retail choice; on-post housing at Fort Hood is a different story.
Last updated . Written by Power Hopper. Reviewed by Brent Ward, founder, on 2026-10-19. Data as of October 5, 2026 (meters) and October 19, 2026 (plan prices).
In short: Every Killeen-addressed home in ERCOT's competitive data is on Oncor's wires (64,846 active residential meters, October 5, 2026). Addresses on Oncor's wires can choose a retail provider, and in Killeen that is nearly everyone our data can see. Your delivery utility handles the wires and outages; the retail provider you choose sets your price and sends the bill.
Who delivers electricity in Killeen?
Every Killeen-addressed home in ERCOT's competitive data is on Oncor's wires (64,846 active residential meters, October 5, 2026). The delivery utility (TDU) owns the poles and wires, reads the meter and restores power; in an outage, contact Oncor at oncor.com/outages, not your retail provider.

Can every address in Killeen choose an electricity provider?
Addresses on Oncor's wires can choose a retail provider, and in Killeen that is nearly everyone our data can see.
EIA’s 2024 utility data also lists these utilities in Bell County: electric co-ops Bartlett Electric Coop, Inc, Heart of Texas Electric Coop, Pedernales Electric Coop, Inc. EIA reports them by county, not by street, so some may not reach Killeen itself; addresses they serve do not have retail choice unless the utility opted in.

Weather and electricity in Killeen
Typical weather near Killeen, from the nearest NOAA station with a complete 1991-2020 record: Killeen, about 2 miles from the city center (station elevation 815 ft). These are normals for that station, not readings at your address. August is the warmest month on average, with a normal daily high of 97°F; January has the coolest average low, 36°F. Average daily highs reach 90°F or more in June to August. No month averages a daily low at or below freezing.
For electricity, the normals point to two seasons that can lift a household's usage: cooling-degree days (a measure of how far each day's mean temperature sits above 65°F) peak in August at 609 for the month, and heating-degree days (below 65°F) peak in January at 536. How much that matters to a bill depends on the home, its insulation, its heating fuel and the household, so use your own usage history, not a regional average, when you compare plans.
| Month | Avg high °F | Avg low °F | Precipitation (in) | Cooling degree-days | Heating degree-days |
|---|---|---|---|---|---|

Historical weather records for Bell County
The Texas Railroad Commission's county table lists a record low of -5°F (1989) and a record high of 112°F (2018), and a regional estimate of 24 consecutive hours as a typical longest freezing or frozen-precipitation period for Bell County. These are historical county extremes, not Killeen's monthly averages and not a forecast; the normals above describe ordinary months.
Reference only: the U.S. Energy Information Administration's 2020 Residential Energy Consumption Survey puts the average Texas household at about 13,440 kWh a year (about 1,120 kWh a month if spread evenly). That is a statewide average for 2020, not Killeen, and not an estimate for your home. EIA source.

Business electricity in Killeen
ERCOT lists 5,921 active business meters with a Killeen address, about one for every 11.0 homes, and 15 meters in ERCOT’s large non-residential class across Killeen’s main ZIP codes. On Oncor’s wires, a business picks its retail provider the same way a home does; larger accounts can also buy from suppliers that sell directly to commercial customers.
Power Hopper compares offers from retail electric providers and direct suppliers for businesses. For high-consumption businesses, we can run a competitive bid so more than one supplier prices the same usage. We can’t promise savings or how many suppliers will bid. Businesses in Texas retail-choice areas can request a rate review online.

Common questions about electricity in Killeen
Is the City of Killeen my electric company?
No. EIA’s 2024 data lists no city-owned electric utility in Killeen; city utility accounts are for city services such as water. All 64,846 Killeen-addressed homes in ERCOT’s data buy electricity from a retail provider and get it over Oncor’s wires.
Can I choose my electric company in Killeen?
Off post and on Oncor's wires, yes. ERCOT lists 64,846 Killeen-addressed homes, all on Oncor (October 5, 2026). On-post housing and some rural co-op areas in Bell County are not on the competitive market.
I'm PCSing to Fort Hood. Do I need an electricity plan?
If you live on post, ask your housing office; on-post homes aren't in the competitive data. If you rent or buy off post in Killeen, Harker Heights or Copperas Cove, you choose a retail provider and can ask for service to start on your move-in date.
