Overview
Hollofield Substation is an operational electrical substation owned by Baltimore Gas & Electric in the United States. It operates at 115 kV, serving the local grid.
Hollofield Substation is an operational electrical substation located in the United States, owned and operated by Baltimore Gas & Electric (BGE). The facility operates at a voltage level of 115 kV, classifying it as a medium-voltage substation that plays a role in regional power distribution. BGE is a regulated utility serving central Maryland, including the Baltimore metropolitan area. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. As a 115 kV facility, it is part of the sub-transmission network, stepping down power from higher voltage transmission lines for local distribution. Typical equipment includes circuit breakers, transformers, and switchgear, often standardized under IEEE and IEC guidelines. Environmentally, the substation is situated in a region with a mix of urban and suburban development. Its operation supports grid stability and reliability for residential, commercial, and industrial customers in the area. The facility's age and specific environmental impact are not detailed, but substations generally have a localized footprint with considerations for electromagnetic fields, noise, and stormwater management.
Environmental context
The substation is located in a region with a temperate climate and mixed urban-suburban land use. Its operation involves managing electromagnetic fields and noise, typical for such facilities. The site's proximity to residential areas may require adherence to local zoning and environmental regulations regarding visual impact and stormwater runoff.
