A First for Atlantic Canada and the Northeast

In December 1999, a major energy project placed Atlantic Canada and the Northeastern United States at the beginning of North America's interstate pipeline network, with close proximity to significant new supplies of natural gas. Known as Maritimes & Northeast Pipeline, this historic project has introduced natural gas - a cleaner burning, efficient and cost competitive energy source - to areas in Nova Scotia, New Brunswick, Maine and the Northeast U.S. that previously did not have access to natural gas.

System Overview

Maritimes & Northeast Pipeline (M&NP) is a 1400-kilometre transmission pipeline system built to transport natural gas from developments offshore Nova Scotia to markets in Atlantic Canada and the northeastern United States. A joint venture of Spectra Energy (77.53%), Emera Inc. (12.92%), and ExxonMobil (9.55%), M&NP is headquartered in Halifax, Nova Scotia and operates an additional business office in Waltham, Massachusetts.

The M&NP system consists of an approximately 30"/24" diameter underground mainline running from Goldboro, Nova Scotia through Nova Scotia and New Brunswick to the Canadian - U.S. border near Baileyville, Maine. The pipeline continues through Maine and New Hampshire into Massachusetts where it connects with the existing North American pipeline grid at Dracut, Massachusetts. The pipeline also extends from Methuen, Massachusetts to Beverly, Massachusetts.

Natural Gas to Market

Since our beginnings in 1999, our system has added many market delivery points in Nova Scotia, New Brunswick, Maine, New Hampshire, and Massachusetts. These locations include:

M&NP also provides natural gas to downstream North American markets through interconnects with Portland Natural Gas Transmission System, Tennessee Gas Transmission, and Algonquin Gas Transmission.
