Overview
Groton Street Substation is an operational electrical substation in the United States, owned and operated by National Grid. It operates at 69 kV, serving the regional grid.
Groton Street Substation is an operational electrical substation located in the United States, owned and operated by National Grid. The facility operates at a voltage of 69 kV, placing it within the sub-transmission or distribution voltage range typical for regional power distribution. As a substation under National Grid's management, it adheres to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for transmission-level assets. The 69 kV voltage level indicates its role in stepping down power from higher transmission voltages for local distribution, often serving industrial, commercial, or residential areas. The substation's location in the northeastern United States places it within a densely populated region with high electricity demand. Its operational status ensures continued grid stability and power delivery to the surrounding community, contributing to the reliability of the regional electrical infrastructure.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal variations can impact electrical demand and grid operations. Its urban or suburban setting means it is integrated into a built environment, with considerations for electromagnetic field management and noise mitigation. Typical substations of this voltage class use air-insulated or gas-insulated switchgear, with environmental management practices for oil containment and SF6 gas handling.
Frequently asked questions
Groton Street Substation is located in the United States, with coordinates approximately 42.668975 N, -71.575257 W. It is within the service territory of National Grid.
Groton Street Substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution substations that step down power from higher transmission voltages for local distribution.
Groton Street Substation is owned and operated by National Grid, a major utility company serving the northeastern United States.
Substations in the United States must comply with NERC reliability standards for grid stability and FERC regulations for transmission assets. Additionally, equipment standards such as IEEE and ANSI guidelines apply to substation design and operation.
A 69 kV substation typically serves as an intermediate step between high-voltage transmission lines (e.g., 115 kV or higher) and lower-voltage distribution networks (e.g., 12 kV). It helps regulate voltage and distribute power to industrial, commercial, and residential customers.
