Overview
Rock Landing Substation is an operational electrical substation in Virginia, United States, owned and operated by Virginia Electric and Power Company. It operates at 230 kV, serving the regional grid.
Rock Landing Substation is an operational electrical substation located in Virginia, United States. Owned and operated by Virginia Electric and Power Company (a Dominion Energy subsidiary), the facility plays a key role in the regional transmission network. The substation operates at 230 kV, a standard high-voltage level for bulk power transmission in the US. As part of the US electrical infrastructure, Rock Landing Substation falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. The 230 kV voltage level indicates it is a transmission-level asset, typically connecting generation sources to distribution networks or interconnecting with other substations. The facility is likely equipped with modern switchgear and protection systems to ensure grid stability. The substation's location in Virginia places it within the PJM Interconnection, one of the largest regional transmission organizations in the US. Its operational status contributes to the reliability of electricity supply for surrounding communities and industrial users. The facility's grid role is critical for maintaining voltage stability and power flow in the region.
Environmental context
The substation is situated in a coastal plain region of Virginia, near the James River and Chesapeake Bay. The area's flat topography and proximity to water bodies can influence grounding and corrosion protection requirements for electrical equipment. The local climate, with humid summers and occasional hurricanes, necessitates robust design for weather resilience. The substation's 230 kV operation requires careful management of electromagnetic fields and adherence to environmental regulations regarding oil containment from transformers.
