Overview
Roxbury Notch Road Substation is an operational electrical substation in Maine, United States, owned and operated by Central Maine Power Company. It operates at 115 kV, serving the local grid.
Roxbury Notch Road Substation is an operational electrical substation located in Maine, United States. Owned and operated by Central Maine Power Company, it is part of 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 a 115 kV substation, this facility plays a role in stepping down power from higher-voltage transmission lines for local distribution. It operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and the North American Electric Reliability Corporation (NERC) for reliability standards. The substation likely includes switchgear, transformers, and protection systems compliant with IEEE and ISO/IEC 61850 standards. The substation serves the rural and semi-rural areas of western Maine, contributing to grid stability and power delivery for residential and commercial customers. Its location near Roxbury Notch Road suggests it supports the local community and possibly industrial loads in the region. The facility is part of Central Maine Power's extensive network, which is critical for energy distribution in the state.
Environmental context
The substation is located in a rural area of Maine, characterized by forested terrain and a cold climate. Electrical infrastructure in such settings must be designed to withstand harsh winter conditions, including ice and snow accumulation on equipment. The site's environmental impact is minimal, with typical considerations for stormwater runoff and electromagnetic fields. The substation's operation supports the local grid without significant ecological disruption.
