Overview
Edgar Substation is an operational electrical substation in Massachusetts, United States, owned and operated by Eversource. It operates at 115 kV, serving the regional grid.
Edgar Substation is an operational electrical substation located in Massachusetts, United States. Owned and operated by Eversource, a major utility in the Northeast, this facility plays a role in the regional transmission and distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission or distribution-level infrastructure. As part of the U.S. electrical grid, Edgar Substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and security, particularly for facilities that interconnect with the broader transmission system. The 115 kV voltage level indicates that this substation likely serves as a distribution hub for local communities or industrial areas. Located in Massachusetts, Edgar Substation supports the electrical infrastructure of a region with high population density and significant energy demand. The substation's operational status and connection to Eversource's network contribute to the reliability of power supply for residential, commercial, and industrial customers. Its role in voltage regulation and power distribution is critical for maintaining grid stability in the area.
Environmental context
The substation is situated in a temperate climate zone in Massachusetts, where seasonal weather variations, including winter storms and summer heat waves, can impact grid operations. The facility's urban or suburban location likely requires careful management of electromagnetic fields and noise to minimize community impact. As part of the regional grid, the substation supports the integration of renewable energy sources, such as wind and solar, which are increasingly deployed in New England.
