Bangor Hydro is responsible for the safe and reliable operation of the electric system in Eastern Maine. The higher voltage power network that carries electricity long distances is considered Transmission, whereas the lower voltage lines that delivery power to a customers home or business is considered Distribution.
The Transmission development component of our business ensures that we assess needs and build or maintain infrastructure such that it can continue to serve current and future customer needs, both reliably and safetly.
Two significant transmission development projects are profiled below. If you wish to learn more about Bangor Hydro's Transmission Development process, please follow the link below to view the Transmission video.
Here are our current Transmission Development projects:
-
Northeast Reliablility Interconnect (NRI)
The Northeast Reliability Interconnect (NRI) is a planned 85-mile long, 345 kilovolt transmission line that will extend from Orrington, Maine to the St. Croix River near Baileyville. There it will interconnect with a similar new line to be built in New Brunswick, linking the electrical systems of Maine and the Canadian Maritimes Provinces.
-
Hancock County Reliability Project (HRCP)
The Hancock County Reliability Project is a planned 115 kV transmission line that will create a redundant and higher capacity connection to Hancock County. It includes a proposed substation in the southern portion of Trenton, and will bring or create a significant improvement to electric reliability in Hancock County. Depending on the route selected, it will be approximately 13 miles in length, and will be co-located with existing lines as much as possible. Existing lines will continue to operate.
