Maritimes & Northeast Pipeline

Maritimes & Northeast Pipeline (M&NP) is a 1,400-kilometre transmission pipeline system built in 1999 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 Canada (9.55%), M&NP is headquartered in Halifax, Nova Scotia. M&NP system capacity is approximately 530 million cubic feet per day.

The M&NP system consists of 30"/24" mainline that runs from the Sable Offshore Energy Inc. (SOEI) gas plant at landfall in Goldboro, through Nova Scotia, New Brunswick, Maine, New Hampshire, and Massachusetts. The mainline interconnects with Portland Natural Gas Transmission System, Tennessee Gas Transmission, and Algonquin Gas Transmission. Through lateral pipelines M&NP serves Canadian markets in Nova Scotia and New Brunswick.

Our customers include natural gas producers; large industrial users such as pulp and paper manufacturers, refineries, power generators; and local distribution companies.

With an established pipeline system in place, M&NP is well-positioned to respond to growth in both East Coast gas supply and end-use markets in Eastern Canada and the US Northeast. Through the addition of compression and pipeline looping, M&NP can flexibly increase its throughput to transport incremental gas supply to market.

By building upon the existing system, M&NP would minimize any environmental impacts and capture further economies of scale, with the potential to lower the overall cost of transport on our system.
