Overview
Dolfield Substation is an operational electrical substation owned by Baltimore Gas and Electric in Maryland, United States. It operates at 115 kV, serving the local grid.
Dolfield Substation is an operational electrical substation located in Maryland, United States. Owned by Baltimore Gas and Electric, it plays a key role in the regional power distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure. As part of the U.S. electrical grid, Dolfield Substation operates under regulatory oversight from the Federal Energy Regulatory Commission (FERC) and adheres to reliability standards set by the North American Electric Reliability Corporation (NERC). The facility likely employs standard substation automation protocols such as IEC 61850 for efficient monitoring and control. The 115 kV voltage level indicates it serves as a critical node for distributing power from higher-voltage transmission lines to local distribution networks. The substation supports the electrical infrastructure of the Baltimore metropolitan area, contributing to grid stability and reliability for residential, commercial, and industrial customers. Its operational status ensures continued service to the community, and its location in a densely populated region underscores its importance in maintaining consistent power supply.
Environmental context
The substation is located in a suburban area near Baltimore, Maryland, which experiences a temperate climate with seasonal variations. The facility's 115 kV voltage level suggests it is part of the sub-transmission network, balancing local load demands. Its urban proximity means it must comply with local noise and electromagnetic field regulations, while its design likely incorporates standard environmental safeguards for oil containment and fire suppression.
