Overview
Elm Street Substation is an operational electrical substation in Maine, United States, operated by Central Maine Power Company. It operates at 115 kV, serving as a key node in the regional grid.
Elm Street Substation is an operational electrical substation located in Maine, United States. Owned and operated by Central Maine Power Company, the facility plays a role in the regional transmission and distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical grid, Elm Street Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The substation likely includes switchgear, transformers, and protection systems that comply with industry standards such as IEEE C37 for high-voltage equipment. The substation's location in Maine places it within the ISO New England (ISO-NE) balancing authority area, which coordinates the region's electricity market and grid operations. Its 115 kV voltage level indicates it serves as a distribution substation, stepping down power from higher transmission voltages to serve local communities and industrial customers. The facility contributes to the reliability of the regional power supply.
Environmental context
The substation is situated in a temperate climate region of Maine, where seasonal weather variations, including winter storms and ice, can impact electrical infrastructure. The facility's design likely incorporates measures to withstand such conditions, such as robust insulation and weatherproofing. Its location in a rural or suburban area may reduce environmental sensitivity compared to urban installations, but proximity to natural habitats requires adherence to environmental regulations for construction and maintenance.
