Overview
Puddledock Road Substation is an operational electrical substation in Maine, USA, owned and operated by Central Maine Power Company. It operates at 115 kV, serving the regional grid.
Puddledock Road Substation is an electrical substation located in Maine, United States, owned and operated by Central Maine Power Company. The facility is operational and plays a role in the regional power distribution network, handling voltage at 115 kV, which is typical for sub-transmission or distribution-level infrastructure. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and is subject to standards for grid reliability and security. As part of Central Maine Power's network, it supports the integration of generation sources and load centers in the state. The 115 kV voltage level indicates it likely serves as a distribution substation stepping down from higher transmission voltages or feeding local distribution circuits. Environmentally, the substation's location in central Maine places it in a region with mixed forest and rural land use. Its operation is critical for maintaining grid stability in the area, supporting residential, commercial, and industrial customers. The facility's age and specific equipment details are not publicly available, but it contributes to the overall reliability of the New England power grid.
Environmental context
The substation is situated in a rural area of Maine, characterized by forests and scattered development. Its 115 kV operation suggests it serves as a distribution node, with potential impacts on local land use and wildlife corridors typical of linear infrastructure. The facility's presence supports grid reliability in a region prone to winter storms, which can affect overhead lines and equipment.
Frequently asked questions
