Overview
Mill Street Substation is an operational electrical substation in the United States, operated by National Grid. It operates at a voltage of 115 kV, serving the local grid.
Mill Street Substation is an operational electrical substation located in the United States, managed by National Grid. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission networks. As part of National Grid's infrastructure, it plays a role in delivering electricity to residential, commercial, and industrial customers in the region. The substation's technical specifications indicate a 115 kV voltage level, which is common for substations that step down power from higher transmission voltages for local distribution. In the United States, such facilities are subject to NERC reliability standards and FERC regulations to ensure grid stability and safety. The substation likely includes switchgear, transformers, and protection systems compliant with industry standards. Mill Street Substation contributes to the reliability of the local electrical grid, supporting National Grid's service area in Massachusetts. Its operational status ensures continued power delivery to the surrounding community. The facility's location and voltage level are typical for substations that serve as critical nodes in the regional power network.
Environmental context
The substation is located in a region with a temperate climate, where seasonal weather variations can impact grid operations. Its urban or suburban setting means it is integrated into the built environment, with considerations for electromagnetic fields and noise mitigation. The facility's age and technology level influence its environmental footprint, though modern substations often incorporate SF6-free switchgear or other eco-friendly alternatives.
