Overview
Graham 46kV Substation is an operational electrical substation in Maine, United States, owned and operated by Bangor Hydro-Electric Company. It plays a key role in local power distribution at 46 kV.
Graham 46kV Substation is an operational electrical substation located in Maine, United States. Owned and operated by Bangor Hydro-Electric Company, it serves as a critical node in the regional power grid, stepping down transmission voltages for local distribution. The substation operates at 46 kV, a common voltage level for sub-transmission and distribution networks in rural and suburban areas. As part of the U.S. electrical infrastructure, this facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). Bangor Hydro-Electric Company, a subsidiary of Emera Maine, is responsible for maintaining grid stability and reliability in the region. The substation likely employs standard switchgear and protection systems compliant with industry standards such as IEEE and NESC. The substation's location in Maine places it within a region characterized by cold winters and significant seasonal demand variations. It supports the local community by ensuring reliable electricity supply to residential, commercial, and industrial customers. Its role in the grid is essential for maintaining voltage stability and power quality in the area.
Environmental context
The substation is situated in a rural area of Maine, where the surrounding environment includes forests and wetlands. Electrical infrastructure in such settings must consider wildlife corridors and vegetation management to prevent outages. The 46 kV voltage level indicates a sub-transmission role, with potential environmental impacts limited to localized electromagnetic fields and land use for access roads and clearings.
