Grassfield Substation - 115 kV Electrical Substation in the United States

Grassfield Substation is an operational electrical substation located in the United States, owned and operated by Dominion Energy. The facility operates at a voltage level of 115 kV, classifying it as a medium-voltage substation that plays a role in regional power distribution. As part of the U.S. electrical infrastructure, Grassfield Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee transmission-level assets to ensure grid stability. The substation's voltage level and equipment are typical for distribution substations that step down power from transmission lines to local networks. The substation's location in the United States places it within a highly regulated and technologically advanced electrical grid. Its operational status and ownership by Dominion Energy, a major utility, indicate its importance in maintaining reliable electricity supply to the surrounding area. The facility contributes to grid resilience and supports community energy needs.

The substation is located in a region with a temperate climate, which influences electrical infrastructure design and maintenance. Voltage levels and equipment age are critical factors for grid stability, and the substation's 115 kV operation suggests it serves urban or suburban areas. The surrounding environment may include residential or commercial zones, requiring careful management of electromagnetic fields and noise.
