Guilford Substation is an operational electrical substation located in Maine, United States. Owned and operated by Central Maine Power Company, the facility plays a key role in the regional power distribution network. With a voltage level of 115 kV, it is classified as a medium-voltage substation, typical for sub-transmission and distribution applications in rural areas. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for grid stability. As part of Central Maine Power's infrastructure, it supports the integration of local generation and load, contributing to the resilience of Maine's electrical grid. Environmental considerations for substations like Guilford include electromagnetic field management and vegetation control to maintain clearances. The facility's rural location minimizes direct impact on urban populations, while its role in distributing power supports community energy needs. The 115 kV voltage level indicates a balance between capacity and local distribution requirements.
Environmental context
The Guilford Substation is situated in a rural area of Maine, where the surrounding landscape includes forests and agricultural land. Substations at this voltage level typically require cleared rights-of-way to prevent vegetation interference, which can affect local ecosystems. The facility's operation involves minimal emissions but contributes to grid reliability, supporting the integration of renewable energy sources common in the region, such as hydroelectric and wind power.
