Schiller Substation - 115 kV Electrical Substation in the United States

Schiller Substation is an operational electrical substation located in the United States, owned and operated by Eversource, a major utility in the Northeast. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation that plays a role in local power distribution and transmission. As a substation operating under the jurisdiction of the United States, it adheres to NERC reliability standards and FERC regulations for grid stability. The 115 kV voltage level is typical for subtransmission or distribution substations, serving to step down power from higher transmission voltages for local distribution networks. The substation's location near Portsmouth, New Hampshire, places it in a region with a mix of urban and coastal environments. Its operational status ensures continued support for the regional electrical grid, contributing to reliable power supply for residential, commercial, and industrial customers in the area.

The substation is situated in a coastal area of New Hampshire, where environmental considerations include proximity to tidal waters and potential impacts on local ecosystems. As an electrical infrastructure facility, its primary environmental interactions involve electromagnetic fields and heat dissipation, which are managed through standard design practices. The site's location in a developed area reduces direct ecological disruption.
