Overview
Stony Hill Substation is an operational electrical substation owned by Eversource in the United States. It operates at 115 kV, serving as a key node in the regional grid.
Stony Hill Substation is an operational electrical substation located in the United States, owned and operated by Eversource. The facility operates at a voltage of 115 kV, placing it within the sub-transmission or distribution voltage range typical for regional power distribution and grid interconnection. As a substation under Eversource's management, it is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for transmission-level assets. The 115 kV voltage level indicates it likely serves as a distribution substation stepping down power from higher transmission voltages to serve local load centers, or as a switching station within the regional network. The substation plays a critical role in maintaining grid stability and reliability for the surrounding area. Its operational status ensures continued power delivery to residential, commercial, and industrial customers. The facility's location in the northeastern United States places it within a region with aging infrastructure, where modernization efforts are ongoing to enhance resilience against extreme weather events.
Environmental context
The substation is located in a region with a temperate climate, where seasonal weather variations can impact grid operations. The surrounding area includes mixed urban and suburban development, with potential environmental considerations related to electromagnetic fields and land use. As part of the electrical infrastructure, the facility adheres to environmental regulations concerning oil containment and wildlife protection.
