Madbury Substation is an operational electrical substation located in Madbury, New Hampshire, United States. Owned and operated by Eversource, a major utility in the Northeast, this facility plays a critical role in the local and regional power distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical grid, Madbury Substation operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and adheres to reliability standards set by the North American Electric Reliability Corporation (NERC). The substation likely employs modern switchgear and protection systems compliant with industry standards such as IEEE C37, ensuring safe and reliable power flow. Eversource's network in New Hampshire integrates this substation into a broader system that serves residential, commercial, and industrial customers. The environmental significance of Madbury Substation lies in its role in maintaining grid stability and supporting the integration of renewable energy sources. Located in a rural area of New Hampshire, the substation helps distribute power from generation sources to end-users, contributing to the region's energy resilience. Its operational status ensures continued service to the community, with Eversource's maintenance practices focusing on minimizing outages and environmental impact.

Madbury Substation is situated in a rural area of New Hampshire, where the surrounding landscape includes forests and agricultural land. The substation's 115 kV voltage level indicates it is part of the sub-transmission network, which is critical for distributing power from higher-voltage transmission lines to local distribution systems. The facility's location away from dense urban centers reduces direct environmental impact, but its role in grid stability supports the integration of distributed energy resources, such as solar and wind, which are increasingly common in the region.
