Overview
Harris Hydro Substation is an operational electrical substation in Maine, United States, owned by Central Maine Power Company. It operates at 115 kV, serving as a key node in the regional transmission grid.
Harris Hydro Substation is an operational electrical substation located in Maine, United States, owned and operated by Central Maine Power Company. The facility operates at a voltage level of 115 kV, classifying it as a medium-voltage substation within the regional transmission network. It plays a role in stepping down power from hydroelectric generation or transmitting electricity to local distribution systems. The substation operates under the regulatory framework of the United States, which includes reliability standards set by the North American Electric Reliability Corporation (NERC) and oversight by the Federal Energy Regulatory Commission (FERC) for transmission-level assets. As part of the Central Maine Power grid, it likely adheres to ISO/IEC 61850 standards for substation automation and communication. The 115 kV voltage level is typical for sub-transmission or distribution substations in rural and semi-urban areas of New England. Located in a rural area of Maine, the substation supports the integration of hydroelectric power into the grid, contributing to the region's renewable energy portfolio. Its operational status ensures reliable electricity supply to surrounding communities and industries. The facility's significance lies in its role within the broader electrical infrastructure of Maine, facilitating power flow from generation sources to end users.
Environmental context
The substation is situated in a rural, forested region of Maine, where hydroelectric power is a key renewable energy source. The 115 kV voltage level indicates it serves as a distribution or sub-transmission node, likely connecting hydro generation to the grid. Its location away from dense urban areas reduces direct environmental impact, though overhead lines may affect local wildlife corridors. The facility supports clean energy integration, aligning with Maine's renewable energy goals.
