Ellsworth Substation is an operational electrical substation located in Maine, United States. Owned and operated by Versant Power, the facility plays a key role in the regional transmission network, stepping down high-voltage electricity for distribution to local communities. The substation operates at a voltage level of 115 kV, which is typical for sub-transmission and distribution substations in the United States. As part of the New England grid, it falls under the reliability standards set by the North American Electric Reliability Corporation (NERC) and is subject to Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE standards. Ellsworth Substation supports grid stability in the Ellsworth area, a region with a mix of residential, commercial, and industrial loads. Its operation is critical for maintaining reliable electricity supply, especially during peak demand periods. The substation's location in a rural-urban interface underscores its importance in connecting remote generation sources to end users.
Environmental context
The substation is situated in a temperate climate zone with cold winters and mild summers, which influences equipment design and maintenance schedules. Its location near residential areas requires careful management of electromagnetic fields and noise. The facility's role in the grid helps integrate renewable energy sources from the region, supporting Maine's clean energy goals.
