About Electricity in Killeen
Killeen is served by Oncor, the transmission and distribution utility for the Central Texas region. As a deregulated area, residents in Killeen can choose their electricity provider from dozens of licensed retail electric providers (REPs).
Rates in Oncor territory fluctuate based on wholesale energy prices, weather patterns, and seasonal demand. The summer months (June through September) typically see the highest electricity demand and rates in Killeen.
When comparing plans, pay attention to the rate at the level your home actually uses — not just the advertised rate. A plan that looks cheap at 2,000 kWh might cost more at 1,000 kWh because of base charges and pricing tiers.
