For several years now, the biggest hurdle to natural gas production growth in the Marcellus/Utica was takeaway constraints — there simply wasn’t enough capacity on gas pipelines out of Appalachia to support a significant bump-up in regional output. Things have been changing though. The Mountain Valley Pipeline and a slew of expansion projects along Transco are allowing increasing volumes of gas to move to and through Virginia and the Carolinas. The proposed Borealis Pipeline across Ohio would enable up to 2 Bcf/d to move down the Texas Gas Transmission system to the Gulf Coast. And, as we discuss in today’s RBN blog, Kinder Morgan is planning several major projects in the Deep South — including the 2.1-Bcf/d Mississippi Crossing and 1.3-Bcf/d South System Expansion 4 projects — to move more gas into Mississippi, Alabama, Georgia and South Carolina. 

Natural gas pipeline takeaway projects under development out of the U.S. Northeast would enable ~10 Bcf/d to flow south from the Marcellus/Utica supply area. About half of that southbound capacity is geared to serve growing power generation demand directly south and east via the Mid-Atlantic states. But another nearly 5.0 Bcf/d is headed southwest to the Louisiana and Texas Gulf Coast for growing LNG export and Mexico demand—and that is on top of about 4.4 Bcf/d of reversal (or backhaul) capacity already added over the past two years. Much of the Gulf Coast-bound backhaul capacity will converge on the Perryville Hub, a market center located in northeastern Louisiana, about 220 miles north of the U.S. national benchmark Henry Hub. As such, the ability for gas to move through Perryville and get to downstream demand market centers will be key to balancing the natural gas markets. Today, we take a closer look at the historical and future pipeline capacity in and around the Perryville Hub.
