NRI The Northeast Reliability Interconnect (NRI) is an 85-mile long, 345 kilovolt transmission line that extends from Orrington, Maine to the St. Croix River near Baileyville. There it interconnects with a similar new line built in New Brunswick, linking the electrical systems of Maine and the Canadian Maritimes Provinces. Map/Route Description Background The North American electric grid upon which our society relies for electric service is built on a backbone of large, interconnected high voltage transmission lines. The Northeast Reliability Interconnect (NRI) is a high voltage transmission line between the Bangor area and New Brunswick, Canada. Although Maine shares over 600 miles of border with Canada, previously only one major backbone transmission line linked the two regions and their electrical system operations. This second line has improved electric system reliability, stability and efficiency in addition to expanding competition and electric energy exchanges between New England and the Maritimes. The Maine section of the line is owned and operated by Emera Maine; the New Brunswick section of the line is owned and operated by New Brunswick Power. Project Purpose The NRI improves reliability and power quality of the electrical system by enhancing the connection between Maine and the Maritimes through an additional link of the two systems. This allows for an increased capability for North-South and South-North electrical flows, thus enhancing trade opportunities. NRI also allows for expansion of competition and market opportunities for Maine and Canada. The project results in a reduction in line losses, which contributes to large-scale energy efficiency and lower costs of import and export delivery. Reliability, stability and power quality improvements, as well as infrastructure investments, all serve to create a more robust electrical system and reduce costs.
