Overview
Double Toll Gate Substation is an operational electrical substation in the United States, operated by Potomac Edison and Rappahannock Electric Cooperative. It operates at 138 kV, serving the regional grid.
Double Toll Gate Substation is an operational electrical substation located in the United States, near coordinates 39.061348, -78.137173. It is jointly operated by Potomac Edison and Rappahannock Electric Cooperative, two major utility providers in the region. The substation operates at a voltage of 138 kV, which classifies it as a medium-to-high voltage facility within the transmission and distribution network. The substation's 138 kV voltage level is typical for sub-transmission and distribution systems in the United States, where NERC reliability standards and FERC regulations govern grid stability and operational safety. As part of the PJM Interconnection, the facility adheres to strict compliance requirements for voltage control and system protection. The equipment likely includes modern switchgear and protection relays to ensure reliable power delivery. This substation plays a critical role in the local electrical infrastructure, supporting residential, commercial, and industrial loads in the surrounding area. Its location in a rural or semi-urban setting of Virginia contributes to grid resilience and energy access. The facility's operational status ensures continued service to the community, aligning with the broader objectives of grid modernization and reliability.
Environmental context
The substation is situated in a region characterized by mixed land use, including agricultural and residential areas. Its 138 kV voltage level indicates a role in distributing power from higher-voltage transmission lines to local distribution networks. The facility's operation is subject to environmental regulations concerning electromagnetic fields and noise, typical for substations in the United States.
