Colington Substation: 115 kV Electrical Substation Operated by Dominion Energy

Colington Substation is an operational electrical substation located in the United States, owned and operated by Dominion Energy. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission substations. As part of Dominion Energy's network, it plays a role in the regional power grid. The substation's technical specifications include a voltage level of 115 kV, which is common for substations that step down transmission voltages for local distribution. In the United States, such facilities are subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with federal guidelines. Dominion Energy, a major utility in the Mid-Atlantic and Southeast, operates numerous substations of this scale to support residential, commercial, and industrial loads. Environmentally, Colington Substation is situated in a coastal area of North Carolina, near the Outer Banks. Its location in a region prone to hurricanes and severe weather underscores the importance of grid resilience. The substation's role in distributing power to local communities highlights its significance for public safety and economic activity, particularly during storm events where reliable electrical infrastructure is critical.
