Pentagon Substation - Operational 115 kV Substation in the United States

Pentagon Substation is an operational electrical substation located in the United States, owned and operated by Evergy. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution-level substations that step down power for local consumption. As a substation within the U.S. electrical infrastructure, it falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability standards. The facility's voltage level of 115 kV is common for sub-transmission systems that connect bulk power transmission to distribution networks, often serving industrial or densely populated areas. The substation's location near the Pentagon complex suggests it plays a critical role in providing reliable power to a high-security government facility. Its operational status and ownership by Evergy, a major utility in the Midwest, indicate it is part of a well-maintained grid system. The facility contributes to grid stability and energy delivery in the region.

The substation is located in a developed urban area near the Pentagon, a major government complex. Its operation involves electromagnetic fields and potential oil leakage from transformers, though modern substations are designed with containment measures. The surrounding environment is predominantly impervious surfaces, with limited natural habitat, reducing direct ecological impact. However, the facility's role in power distribution supports energy-intensive activities in the region.
