Overview
Peninsula Substation is an operational 115 kV electrical substation owned and operated by Dominion Energy in the United States, serving grid stability in the Virginia region.
Peninsula Substation is a 115 kV electrical substation located in the United States, owned and operated by Dominion Energy. As a medium-voltage substation, it plays a critical role in stepping down transmission-level power for local distribution, supporting residential and commercial loads in the Hampton Roads area. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for voltage control and grid stability. Dominion Energy, a major utility in the Mid-Atlantic, maintains this facility as part of its extensive transmission network, which integrates with the PJM Interconnection regional grid. Peninsula Substation contributes to the resilience of the local electrical infrastructure by facilitating power flow between transmission lines and distribution networks. Its location near the Virginia Peninsula supports critical infrastructure for military, industrial, and urban consumers, underscoring its importance in maintaining reliable electricity supply in the region.
Environmental context
The substation is situated in a coastal urban area of Virginia, where electrical infrastructure must withstand hurricane risks and saltwater corrosion. The 115 kV voltage level indicates a medium-scale facility that balances local grid demands with environmental considerations, such as minimizing electromagnetic field impacts and ensuring storm resilience through robust design.
