Frederick Street Substation - Operational Substation in United States

Frederick Street Substation is an operational electrical substation located in the United States, owned and operated by the Washington Metropolitan Area Transit Authority (WMATA). The facility plays a critical role in providing electrical power to the Washington, D.C. metropolitan area's transit system, including the Metrorail and Metrobus networks. As a substation, it steps down high-voltage transmission power to lower voltages suitable for transit operations. The substation operates at two voltage levels: 34.5 kV for primary distribution and 700 V for traction power, which is typical for rail transit systems. The facility is part of WMATA's extensive electrical infrastructure, which includes multiple substations and power distribution networks. In the United States, such substations are subject to NERC reliability standards and FERC regulations for grid interconnection, though transit-owned substations may have additional local oversight. The environmental context of Frederick Street Substation is urban, located in a densely populated area near transit corridors. Its operation supports electric-powered public transportation, reducing reliance on fossil-fuel vehicles and contributing to lower urban emissions. Typical urban transit substations are maintained to high reliability standards to ensure uninterrupted service.

Located in an urban setting, Frederick Street Substation supports electric transit, reducing vehicular emissions. Its operation is critical for grid stability in the Washington, D.C. area, and its voltage levels indicate a role in both distribution and traction power. The substation's age and switchgear condition are not detailed, but urban substations often face challenges related to space constraints and aging infrastructure.
