Overview
Dogtown Substation is an operational electrical substation owned by Central Maine Power Company in Maine, United States. It operates at 115 kV, serving as a key node in the regional transmission grid.
Dogtown Substation is an operational electrical substation located in Maine, United States, and owned 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. As part of the New England power grid, it plays a role in distributing electricity from generation sources to local distribution systems. The substation is regulated under the jurisdiction of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and require regular maintenance and operational protocols. The 115 kV voltage level is typical for sub-transmission substations that connect high-voltage transmission lines to lower-voltage distribution networks. Dogtown Substation contributes to the electrical infrastructure serving central Maine, supporting residential, commercial, and industrial customers in the region. Its operational status and ownership by Central Maine Power Company, a major utility in the state, underscore its importance in maintaining reliable electricity supply. The facility's location in a rural area may influence its design and maintenance practices, focusing on resilience against weather-related disruptions common in the region.
Environmental context
The substation is located in a rural area of Maine, characterized by forests and cold winters. Its operation involves managing electrical equipment that may contain insulating oils and SF6 gas, which require careful handling to prevent environmental contamination. The site's proximity to natural habitats necessitates adherence to environmental regulations regarding spill prevention and wildlife protection. The 115 kV voltage level indicates moderate electromagnetic fields, which are managed within safety standards.
