Longwood Substation - Operational Substation in the United States

Longwood Substation is an operational electrical substation located in the United States, with coordinates 38.860353, -76.061780. It operates at voltage levels of 69 kV and 12.47 kV, indicating a distribution-level facility that steps down transmission voltage for local distribution. The substation's voltage configuration suggests it plays a role in the regional power grid, likely serving residential, commercial, or industrial customers in its vicinity. As a substation in the United States, it operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and may be subject to Federal Energy Regulatory Commission (FERC) jurisdiction if interconnected with the bulk power system. The facility's operational status and location in a populated area underscore its importance for maintaining grid stability and reliability. Substations like Longwood are critical for voltage regulation and power distribution, contributing to the overall resilience of the electrical infrastructure in the region.

The substation is located in a region with a temperate climate, which influences the design and maintenance of electrical equipment. Its urban or suburban setting may require considerations for electromagnetic field exposure and noise mitigation. The facility's operation supports local energy needs while adhering to environmental regulations for equipment insulation and oil containment.
