Halfway Substation - 138 kV Operational Substation in the United States

Halfway Substation is an operational electrical substation located in the United States, with coordinates 39.635787, -77.780164. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation that contributes to the transmission and distribution of electricity within the regional grid. Operating under the regulatory framework of the United States, this substation adheres to NERC reliability standards and FERC regulations for transmission-level assets. The 138 kV voltage level is typical for sub-transmission or distribution substations, serving to step down power from higher transmission voltages for local distribution networks. The substation's location in a rural or suburban area of the United States supports grid reliability and electricity supply to surrounding communities. Its operational status ensures continued service, contributing to the overall stability and resilience of the electrical infrastructure in the region.

The substation's location in the United States, with a voltage of 138 kV, indicates it is part of the sub-transmission network, which typically serves to distribute power to local areas. The environmental context includes considerations of land use, electromagnetic fields, and potential impacts on local wildlife. Substations of this scale are generally designed with mitigation measures to minimize ecological disruption.
