Overview
Slayton Hill Substation is an operational electrical substation in the United States, owned and operated by National Grid. It operates at a voltage of 115 kV, serving as a key node in the regional transmission network.
Slayton Hill Substation is an operational electrical substation located in the United States, owned and operated by National Grid. The facility operates at a voltage of 115 kV, placing it within the sub-transmission or distribution voltage range typical for regional power distribution in the US grid. As a substation owned by National Grid, a major utility in the northeastern US, Slayton Hill Substation is subject to NERC reliability standards and FERC regulation 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 local distribution networks, or as a sub-transmission node interconnecting regional grids. The substation's location in a rural or semi-rural area of New Hampshire suggests it plays a critical role in maintaining grid stability for surrounding communities. Its operational status ensures continued reliability of electrical supply to local residential, commercial, and industrial customers, supporting the region's energy infrastructure.
Environmental context
The substation is situated in a region with mixed forest and rural land use, typical of New Hampshire's landscape. Electrical infrastructure at this voltage level can have localized environmental impacts, such as electromagnetic fields and land use for transmission corridors. The facility's operation is subject to environmental regulations including the National Environmental Policy Act (NEPA) for any upgrades or expansions, ensuring minimal ecological disruption.
