Killeen Fort Hood Substation is an operational electrical substation located in Texas, United States. Owned and operated by Oncor, a major transmission and distribution utility in Texas, this facility plays a key role in the regional power grid. The substation handles voltages of 138,000 volts (138 kV) and 25,000 volts (25 kV), indicating it serves both transmission and distribution functions. As part of the US electrical infrastructure, this substation operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for interstate transmission and the Public Utility Commission of Texas (PUCT) for intrastate matters. Reliability standards set by the North American Electric Reliability Corporation (NERC) apply, ensuring grid stability and security. Oncor, as the operator, adheres to these standards and also follows industry best practices for substation automation and protection, such as those outlined in IEC 61850. The substation's location near Fort Hood, a major US Army installation, underscores its strategic importance for both civilian and military power needs. It supports the local community and critical infrastructure, contributing to the resilience of the Texas Interconnection grid. The dual voltage levels allow for efficient power distribution to residential, commercial, and industrial customers in the region.
Environmental context
The substation is situated in central Texas, a region characterized by hot summers and mild winters, which drives high electricity demand for air conditioning. Its proximity to Fort Hood means it supports a large military base with critical power needs. The surrounding area includes both urban development and open landscapes, requiring careful management of electromagnetic fields and visual impact. Oncor likely implements standard environmental practices such as oil containment for transformers and vegetation management to prevent outages.
