Killeen is the largest city in Bell County and one of the most distinctively military-influenced cities in the United States — home to the civilian community surrounding Fort Cavazos (formerly Fort Hood), the largest active-duty military installation in the country by land area. With a population over 150,000, Killeen has a high proportion of military families, a large rental market with frequent turnover, and a housing stock dominated by 1970s–2000s single-family homes and apartment complexes. Every off-post Killeen address is within Oncor Electric Delivery's deregulated service territory.
The short answer
Killeen ZIP codes 76540–76549 are Oncor Electric Delivery territory — fully deregulated. On-post Fort Cavazos housing is not part of the competitive market; off-post residential addresses are. Fixed-rate plans as of May 2026 advertise 9.5–13.5¢/kWh at 1,000 kWh. Typical summer usage: 1,000–1,600 kWh. Military families inheriting a rental unit should check their plan type immediately.
Oncor in Killeen — Bell County Service Area
Oncor Electric Delivery serves Killeen, Harker Heights, Copperas Cove (Coryell County), and the broader Bell County area as the regulated TDU. Oncor's TDSP charges — a fixed customer fee and per-kWh distribution charge — appear on every bill regardless of REP. At 1,000 kWh, these charges typically total $8–$13. At 1,500 kWh in summer, they rise to $13–$19.
The competitive plan market in Killeen ZIPs is the same broad market available throughout Oncor's territory — typically 60–90 active plans from 20+ providers. Because the Killeen market has high residential turnover, REPs that are aggressive in the rental market maintain a strong presence here.
Killeen ZIP Codes and Usage Profiles
| ZIP | Area | Typical Housing | Summer Usage |
|---|---|---|---|
| 76540/76541 | Central Killeen | 1970s–1990s, mix of single-family and apartments | 900–1,400 kWh |
| 76542/76543 | East/South Killeen | 1980s–2000s single-family, 1,200–2,000 sq ft | 1,000–1,500 kWh |
| 76549 | NW Killeen / near Fort Cavazos gate | Mixed, high rental density near post | 900–1,400 kWh |
A Texas example
Sergeant First Class Williams and his family moved to a rental in Killeen (76542) in June after arriving from Fort Campbell, Kentucky. They were placed on the landlord's holdover plan — a variable rate that had ballooned to 15.8¢/kWh after the previous tenant's fixed term expired. August bill: $276.40 for 1,380 kWh. Within a week of switching to a 12-month fixed plan at an interpolated rate of 10.4¢/kWh, their identical September usage (1,280 kWh) produced a bill of $161.70 — a difference of $114.70 in a single month. The holdover plan trap is especially common in high-turnover military rental markets.
The Military Rental Market and Plan Traps
Killeen's high military population creates a rental market where units change tenants every 2–3 years. When a lease ends and a unit sits vacant, the account often reverts to a month-to-month holdover variable rate with the previous tenant's REP — sometimes at rates 30–60% above what was originally contracted. The incoming tenant or new lease may not be notified of this, and the first bill is a shock.
Military families arriving at Fort Cavazos should take three immediate steps: (1) confirm the current electricity plan type — variable or fixed; (2) if variable, shop immediately using the search tool; (3) sign a fixed-rate contract that extends beyond your anticipated PCS date (or use a plan with a low early termination fee for flexibility). SCRA (Servicemembers Civil Relief Act) protections may allow early contract termination without ETF if you receive orders — consult your legal assistance office for specifics.
Watch out
Some electricity providers specifically market door-to-door in military communities near Fort Cavazos. These representatives may offer plans that appear competitive but include longer contract terms (24–36 months), high early termination fees, or bill-credit structures that look attractive at 1,000 kWh but cost more at actual usage levels. SCRA ETF protections do not always override commercial contract terms — read the EFL before signing. Compare any door-to-door offer against the search tool's ranked results at your expected usage level.
Smart move
If you know your PCS date, choose a plan term that ends 1–2 months before departure. This avoids early termination fees while keeping you on a fixed rate for the full period you're in Killeen. A 12-month plan signed in July runs through next June — if orders arrive for an August departure, you avoid the ETF entirely. The True Cost Calculator lets you model the total cost over a custom number of months to find the most cost-effective term for your timeline.
Key Takeaways
Killeen ZIP codes 76540–76549 are Oncor territory — delivery charges are fixed. Off-post residential addresses are fully in the competitive market; on-post housing is not. High rental turnover creates holdover variable-rate traps that military families should address immediately upon arrival. Compare plans at your actual usage level and choose a fixed-rate term aligned with your expected tour length.

Can military families at Fort Cavazos shop for competitive electricity?
On-post housing at Fort Cavazos (the military installation itself) is typically served by the Army's utilities management program and is not in the competitive retail market. Off-post housing in Killeen and Harker Heights ZIP codes is fully deregulated — military families living off base can shop for competitive plans exactly like any other Texas resident.
Why is electricity plan comparison especially important for Killeen military families?
Military families rotate in and out of the Killeen market frequently — 2–3 year duty station cycles are common. This creates high rental market turnover, and landlords often enroll vacant units in holdover variable-rate plans when a lease ends. A new tenant may inherit a variable-rate plan without realizing it. Active-duty families moving to Killeen should immediately check their plan type and switch to a fixed rate if they find themselves on a variable or holdover plan.
