Overview
Detroit Substation is an operational electrical substation in Detroit, Maine, owned and operated by Central Maine Power Company. It operates at 115 kV, serving as a key node in the regional transmission grid.
Detroit Substation is an operational electrical substation located in Detroit, Maine, United States. Owned and operated by Central Maine Power Company, the facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation within the regional transmission network. The substation plays a role in distributing electricity from higher-voltage transmission lines to local distribution systems, supporting the power needs of the surrounding area. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. As part of Central Maine Power's infrastructure, it adheres to NERC's Critical Infrastructure Protection (CIP) standards and FERC's regulations for transmission-level assets. The 115 kV voltage level is typical for sub-transmission and distribution substations in the United States, balancing capacity and safety for regional grid stability. Environmentally, the substation is situated in a rural area of Maine, characterized by forests and low population density. Its operation involves minimal direct environmental impact, though it supports the integration of renewable energy sources like wind and hydro power common in the region. The facility's role in grid reliability contributes to the community's access to stable electricity, essential for residential, commercial, and industrial activities in central Maine.
Environmental context
The substation is located in a rural, forested area of Maine, with low population density. Its 115 kV operation has minimal direct environmental footprint, but it supports the integration of regional renewable energy sources such as wind and hydroelectric power. The facility's grid role enhances energy reliability for the surrounding community, reducing dependence on less efficient local generation.
