Killeen Clear Creek Substation - Oncor Electrical Substation in Killeen, Texas

Killeen Clear Creek Substation is an operational electrical substation located in Killeen, Texas, United States. Owned and operated by Oncor, a major transmission and distribution utility in Texas, the facility plays a key role in the regional power grid. The substation handles multiple voltage levels, including 138 kV for transmission and 25 kV and 12.5 kV for distribution, indicating its function as a step-down substation serving both industrial and residential customers. As part of the U.S. electrical infrastructure, the substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). Oncor, as a transmission service provider, must comply with NERC reliability standards to ensure grid stability. The substation's voltage levels and equipment are typical for medium-to-large substations in the region, supporting the growing energy demands of the Killeen area. The substation's location in Killeen, near the Fort Hood military installation, underscores its importance for critical infrastructure reliability. It contributes to the resilience of the local grid, providing power to residential, commercial, and military facilities. The operational status and integration with Oncor's network highlight its role in maintaining continuous electricity supply in central Texas.

The substation is situated in an urban area of Killeen, Texas, a region with a hot semi-arid climate. Electrical infrastructure in such environments must withstand high temperatures and occasional severe weather, including thunderstorms and heatwaves. The substation's design likely includes measures for thermal management and flood protection. Its proximity to Fort Hood adds strategic importance, requiring robust security and reliability to support military operations.
