If all the pipeline projects that are currently planned get built, there would be 18 Bcf/d of new capacity by 2019.  However, the most optimistic projection for increased Marcellus/Utica gas production is 11 Bcf/d over the next five years.  Most likely the growth would be less at current gas prices.

So which pipelines will get dropped?  The Utopia pipeline project already dropped one line from their two line plan.  Rover and Nexus are headed for the same destination (Canada) and Rover is way ahead of Nexus in terms of FERC status as well as having a lower sell price at the destination.  Will Nexus be next on the chopping block?
