Enbridge/DTE Energy’s 1.5-Bcf/d NEXUS Gas Transmission pipeline saw its first natural gas flows this week, as the Federal Energy Regulatory Commission (FERC) approved partial service on the project, opening another nearly 1 Bcf/d of capacity from Appalachia’s Marcellus/Utica producing region to the Midwest. NEXUS marks the last big westbound takeaway project from the Northeast, except for the remaining pieces of Energy Transfer’s (ETP) Rover Pipeline. It also marks the escalation of gas-on-gas competition in the Midwest market, where U.S. Midcontinent and Canadian gas supplies are also battling it out for market share. Today, we take a closer look at the NEXUS project and its potential implications for the Northeast and Midwest gas markets.

For years, the U.S. Midwest has been a perennial net exporter of natural gas to Eastern Canada. But with Marcellus/Utica and Canadian gas supplies barraging the region, that’s changing. Less Midwest gas is flowing across the border into Ontario. At the same time, Canadian gas supply that used to serve U.S. Northeast demand is being displaced to the Midwest. That’s on top of Marcellus/Utica gas that’s physically moving to the Midwest via new capacity on the Rockies Express and Rover pipelines. The result is that the Midwest’s net exports to Canada are declining and even flipping into net imports during some summer months when the market is in storage injection mode. Thus far, this reshuffling of supply has occurred at the expense of Gulf and Midcontinent gas that historically has served the Midwest. But now there’s little of that left to displace from the Midwest, even as still more supply is expected to move there. Canadian producers are banking on capturing more of the Midwest market, as are Northeast producers via expansions like Rover’s Phase II and NEXUS. In other words, there’s a fierce battle brewing for Midwest market share. Today, we look at flow dynamics and factors affecting Canadian gas flows to the U.S. Midwest.
