Overview
Robley Substation is an operational electrical substation in the United States, operating at 34.5 kV. It plays a role in regional grid stability and power distribution.
Robley Substation is an operational electrical substation located in the United States, with coordinates 37.851250, -76.578310. The facility operates at a voltage of 34.5 kV, classifying it as a medium-voltage substation typical of distribution-level infrastructure. As a substation, it serves as a node in the electrical grid, stepping down transmission voltages for local distribution or interconnecting generation sources. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for grid stability and FERC oversight for interstate transmission. At 34.5 kV, this facility is likely part of a sub-transmission or distribution network, supporting local electricity delivery. The technology employed is standard for such substations, including switchgear, transformers, and protection systems. Environmentally, the substation's location in a rural area of Virginia suggests it supports agricultural or residential loads, with minimal direct environmental impact. Its role in the grid contributes to reliable power supply for the surrounding community, aligning with sector significance in maintaining electrical infrastructure resilience.
Environmental context
The substation is situated in a rural area of Virginia, characterized by mixed forest and agricultural land. Its operation at 34.5 kV indicates a distribution-level facility with localized grid impact. The environmental context includes potential electromagnetic fields and land use for infrastructure, typical of substations in such settings.
Frequently asked questions
Robley Substation is located in the United States, with approximate coordinates 37.851250, -76.578310. It is situated in a rural area of Virginia.
Robley Substation operates at a voltage of 34.5 kV, which is typical for a distribution-level substation in the United States.
However, substations in the United States are typically operated by local utilities or transmission system operators.
As a substation in the United States, Robley Substation is subject to NERC reliability standards for grid stability and may fall under FERC jurisdiction if it is part of interstate transmission. Compliance with IEEE and ANSI standards for substation equipment is also typical.
A 34.5 kV substation typically serves as a distribution substation, stepping down voltage from higher transmission levels (e.g., 69 kV or 115 kV) to lower distribution voltages (e.g., 12.47 kV or 4.16 kV) for local delivery to homes and businesses.
