In Killeen, electric delivery is handled by Oncor — and since Killeen sits in Texas's deregulated market, you pick your own Killeen retail plan; Atmos Energy is Killeen's natural-gas utility; City of Killeen handles Killeen's water and sewer. The exact lineup depends on your Killeen address — even nearby Round Rock and Waco answer differently.

Killeen grew up around Fort Cavazos, and its utility lineup follows the Central Texas pattern: deregulated electricity over one delivery utility for most addresses, regional gas, city water and sewer. West toward Copperas Cove and out into rural Bell County, co-op electric territory appears.
Killeen's rhythm follows Fort Cavazos: PCS season concentrates moves into early summer and off-post rentals turn over fast. The lineup itself is standard Central Texas — it's the timing crunch that catches people, so start the process before the truck is loaded.
Plenty of Killeen households do this dance every two or three years, and the veterans of it have the sequence down. Line up start dates so the retail electric plan is live before the truck arrives — at most Killeen addresses, Oncor delivers the power no matter which plan you pick — then add the Atmos Energy gas account if the house calls for one, and put City of Killeen water and sewer in your name last. Closing out the old address matters just as much: final water reads and plan cancellations left dangling are the classic move-out snag when orders come through in a hurry. None of it is hard; it rewards doing in order, and the lookup is the two-minute first step that keeps the rest boring.

Oncor — Killeen's TDU — owns the wires here, the same delivery setup as Killeen's neighbors Round Rock and Waco, and restores Killeen outages ((888) 313-6862) whoever you pay. Your separately chosen Killeen plan (compare at Power to Choose) sets the rate on your Killeen bill — full wires-vs-plans explainer here.
Killeen is standard Central Texas: plan first, city water second, gas only if your home uses it.
Oncor is the TDU for Killeen — the wires-and-meters utility — at most of the Killeen addresses we sampled. You pick the retail plan that sets your Killeen rate; Oncor delivers either way.
At every one of the Killeen addresses we sampled, City of Killeen was the water provider — sewer included. Other districts take over around Killeen's edges, so check your block.
No — at every one of the sampled Killeen addresses, Atmos Energy was the gas utility, but plenty of Killeen homes are all-electric and never open this account.
Living off-post, yes — the standard Killeen lineup applies. On-post housing generally handles utilities through the installation's housing program instead of individual city accounts, so check with your housing office first.
Our sampling found a co-op at a small share of addresses on the city's edges, while Oncor delivered to nearly all the rest — another case where two nearby addresses can follow different rules.
Each is its own city with its own water department, and the co-op edges west of Killeen shift the electric answer too. Killeen's lineup applies inside Killeen — give each address its own lookup.
At most Killeen addresses, the company you picked only sells the plan — Oncor owns the poles and wires, so outages and downed lines are Oncor's to fix no matter whose name is on your bill. That split confuses a lot of first-time Texans. The exception is the handful of addresses in Bartlett Electric Cooperative territory, where the co-op is both the plan and the wires. The lookup shows which setup your address has before you sign anything.
