Overview
Interconnection Substation, operated by Dominion Energy in the United States, is a 230 kV substation that plays a key role in regional grid stability and power distribution.
Interconnection Substation is a high-voltage electrical substation located in the United States, operated by Dominion Energy. With a voltage level of 230 kV, it is classified as a transmission-level substation, critical for stepping down power from high-voltage transmission lines to lower voltages for distribution. The facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight. Operating at 230 kV, this substation is typical of large-scale infrastructure that interconnects major transmission corridors. Dominion Energy, a major utility in the Mid-Atlantic and Southeast, manages this asset to ensure reliable electricity flow. The substation likely includes modern switchgear and automation systems compliant with ISO/IEC 61850 standards, enhancing grid resilience and monitoring capabilities. The environmental context of this substation involves its role in supporting urban and suburban load centers. Its location in a region with diverse energy sources, including natural gas, nuclear, and renewables, underscores its importance in balancing supply and demand. The facility contributes to grid stability, reducing the risk of outages and supporting economic activity in the surrounding area.
Environmental context
The substation's location in a mixed urban-suburban area of the United States places it within a grid that integrates renewable energy sources like solar and wind. Its 230 kV voltage level is typical for regional transmission, and the facility's age and technology influence its environmental footprint.
