Overview
N92TBS1 Baldwin Drive is an operational substation in the United States, owned by the Washington Metropolitan Area Transit Authority. It operates at 34.5 kV and 750 V, supporting transit electrical infrastructure.
N92TBS1 Baldwin Drive is an operational electrical substation located in the United States, owned and operated by the Washington Metropolitan Area Transit Authority (WMATA). The facility serves as a critical node in the transit authority's power distribution network, stepping down high-voltage transmission power for use in rail and bus systems. With voltage levels of 34.5 kV and 750 V, it supports both medium-voltage distribution and low-voltage traction power needs. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring grid stability and reliability. As part of WMATA's infrastructure, it adheres to stringent safety and operational standards typical of transit-oriented electrical assets. The facility's dual-voltage capability reflects the specialized requirements of urban transit systems, where both high-capacity distribution and low-voltage traction power are essential. Located in the Washington, D.C. metropolitan area, this substation plays a vital role in powering one of the nation's busiest public transit networks. Its operational status ensures continuous service for commuters, contributing to reduced traffic congestion and lower emissions in the region. The facility's integration with WMATA's broader electrical grid underscores its importance in maintaining reliable and efficient transit operations.
Environmental context
The substation is situated in an urban environment within the Washington, D.C. metropolitan area, a region with high population density and significant transportation infrastructure. Its operation supports electrified transit, which reduces reliance on fossil-fuel vehicles and lowers local air pollution. The surrounding area is subject to typical urban environmental considerations, including stormwater management and electromagnetic field regulations.
