Atlantic Coast Pipeline

Natural gas pipeline project permitting sits at the nexus of the debate about the best path toward decarbonization. Industry proponents rightly point out that pipelines can reduce aggregate emissions by displacing much higher burner-tip emissions from coal in power generation. Environmental opposition, though, highlights that a high rate of methane emissions along the gas value chain could undermine those potential improvements. In today’s RBN blog, we consider the net decarbonization impact of new gas pipelines, including the importance of quantifying upstream methane emissions, by looking at a couple of canceled or long-delayed pipeline projects that could make a big difference.

With recent project completions, Northeast takeaway constraints have eased, and regional supply prices have strengthened. But now the slate of planned pipeline expansions is dwindling. Between late-2015 and the end of 2018, midstreamers will have completed 23 takeaway projects out of Appalachia, totaling nearly 14.5 Bcf/d of capacity. That leaves just a handful of projects with little more than 6 Bcf/d of capacity to come, most of them facing stiff environmental opposition, regulatory turmoil and higher costs. Yet, as Appalachian gas production continues to grow, these projects will be critical to keeping the takeaway constraints and depressing supply pricing from returning, at least for a little longer. More than half of the remaining capacity would come from two competing projects — Dominion Energy’s Atlantic Coast Pipeline (ACP) and EQM Midstream Partners’ Mountain Valley Pipeline (MVP) — both greenfield efforts tied to growing gas-fired power generation demand along the Mid- and South-Atlantic seaboard and both embattled by a barrage of legal challenges. In today’s blog, we provide an update on the Atlantic Coast and Mountain Valley projects, including the latest status and timing.

Of the 18 Bcf/d of incremental pipeline takeaway capacity out of the Marcellus/Utica that is due to come online over the next few years, nearly one-third is heading to demand markets in the Southeast via the Atlantic Coast states. The southeastern U.S is a fast-growing region, and its residents and businesses are becoming increasingly dependent on gas-fired power generation –– a real boon to Northeast gas producers. Today, we continue our look at how pipeline takeaway capacity will stack up against Northeast production over the next several years, this time with a focus on projects that will move gas to the Southeast.

We talk a lot here in the RBN blogosphere about the bearish market effects of the Shale Revolution, and frequently highlight the U.S. Northeast natural gas region — rapidly growing gas production from the Marcellus/Utica; oversupplied, trapped-gas conditions; and resulting regional price discounts. These dynamics are driving massive investments in pipeline reversals, expansions and new capacity to move the gas to market. Northeast producers are counting on that increase in takeaway capacity to relieve price pressure and balance the market.  But all this gas moving out of the region needs a home.  Fortunately, new demand is emerging, from exports (to Mexico and overseas LNG) and into the U.S. power sector.  One of the big growth regions is the U.S. Southeast, where power utilities are investing heavily in building out their fleet of gas-fired generation plants and are banking on this new, unfettered access to cheap Marcellus/Utica gas supply. Today’s blog provides an update on power generation projects coming up in the southern half of the Eastern Seaboard, based on a recent report by our good friends at Natural Gas Intelligence — “Southern Exposure: Gas-Fired Generators Rising in the Southeast; But Will Northeast Gas Show Up?”
