Overview
Emera Maine is an operational electrical substation located in the United States, operating at 69 kV. It plays a role in regional power distribution and grid stability.
Emera Maine is an operational electrical substation situated in the United States, with coordinates approximately 46.71°N, -67.95°W. The facility operates at a voltage level of 69 kV, which is typical for sub-transmission and distribution substations that serve local communities and industrial areas. As part of the broader North American power grid, this substation contributes to the reliable delivery of electricity to end-users. The substation operates under the regulatory framework of the United States, which includes compliance with NERC reliability standards for grid stability and FERC oversight for transmission-level assets. The facility's voltage level suggests it is a medium-voltage substation, likely serving a mix of residential, commercial, and industrial loads in the region. Such substations are critical for stepping down voltage from higher transmission lines to distribution levels. Environmentally, the substation's location in a rural or semi-rural area of Maine implies it supports the local electrical infrastructure, which is essential for community services and economic activities. The facility's operational status ensures continued grid connectivity, and its age and technology are typical for substations of this scale, with standard switchgear and protection systems in place to maintain safety and reliability.
Environmental context
The substation is located in a region of Maine characterized by forested landscapes and a cold climate. Its operation supports local grid stability, which is important for communities that may experience harsh winters and variable energy demand. The facility's voltage level and rural setting suggest it is part of a distribution network that serves dispersed populations, with potential environmental considerations related to land use and wildlife corridors.
Frequently asked questions
Emera Maine is a substation located in the United States, with approximate coordinates 46.71°N, -67.95°W, likely in the state of Maine.
Emera Maine operates at a voltage of 69 kV, which is a common voltage for sub-transmission and distribution substations.
Emera Maine is currently operational, meaning it is actively serving the electrical grid.
In the United States, substations must comply with NERC reliability standards for grid stability and FERC regulations for transmission assets. Additionally, equipment may follow IEEE standards.
A 69 kV substation typically steps down voltage from higher transmission lines (e.g., 115 kV or 230 kV) to distribution levels (e.g., 12 kV or 34.5 kV) for local delivery to homes and businesses.
