Overview
Tunis Substation is an operational electrical substation in the United States, owned and operated by Virginia Electric & Power Company. It handles voltages of 115 kV and 34.5 kV, serving the regional grid.
Tunis Substation is an operational electrical substation located in the United States, owned and operated by Virginia Electric & Power Company, a subsidiary of Dominion Energy. The facility is situated in the state of Virginia, near the town of Tunis, and plays a role in the regional transmission and distribution network. The substation operates at voltage levels of 115 kV and 34.5 kV, indicating its function in stepping down power from high-voltage transmission lines to lower-voltage distribution networks. As part of the Dominion Energy system, it is subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC) for interstate electricity transmission. This substation contributes to grid stability in the region, supporting residential, commercial, and industrial customers. Its location in a rural area of Virginia underscores its importance in delivering electricity to communities and ensuring reliable power supply. The facility's operational status and integration into the broader electrical infrastructure highlight its role in maintaining energy security.
Environmental context
The substation is located in a rural area of northeastern North Carolina, near the border with Virginia. The surrounding landscape is primarily agricultural and forested, with the nearby Chowan River and Albemarle Sound influencing local hydrology. Electrical infrastructure in such settings must consider potential impacts on wildlife and habitats, though substations typically have a small footprint. The facility's operation aligns with regional grid reliability requirements, balancing energy delivery with environmental stewardship.
