Headed for Heartbreak, Part 5 - Appalachia Gas Flows to the Midwest Rising, But Constraints Loom

Natural gas pipeline takeaway capacity additions out of the Northeast over the past year or two, along with suppressed gas production growth in recent months, have relieved years-long and severe constraints for moving Marcellus/Utica gas out of the region and even left some takeaway pipelines less than full. That, in turn, has supported Appalachian supply prices. Basis at the Dominion South hub in the first five months of 2019 averaged just $0.26/MMBtu below Henry Hub, compared with $0.46 below in the same period last year and nearly $1.00 below back in 2015, when constraints were the norm. Today, we continue our series providing an update on pipeline utilization out of the region, and how much spare capacity is left before constraints reemerge.

Natural gas pipeline takeaway constraints out of the Northeast worsened in 2020 despite producer cutbacks in the region as high storage levels and weaker demand led to record volumes of Appalachian gas supplies needing to find outlets in other regions last fall. This year, storage levels are lower and could absorb more of the surpluses during injection season. However, Appalachian gas production so far in 2021 has been averaging higher than last year; and, gas prices are higher year-on-year, reducing prospects for the kinds of producer curtailments we saw last year. As for the “pull” from downstream demand, LNG exports along the Gulf Coast aren’t expected to experience the slump from cargo cancellations seen last summer. In other words, Appalachia’s outbound flows are likely to be robust, setting the stage for takeaway constraints and weak prices, particularly during the spring and fall shoulder seasons. How much outbound capacity currently exists and how much room is there for growth? Today, we continue our series on the Northeast gas market with an update on Appalachia’s southbound takeaway capacity and outflows, starting with a detailed look at the gas moving to the Southeast and to the Gulf Coast.

Just two years ago, severe transportation constraints and steep price discounts were part and parcel of the Northeast natural gas market. Midstreamers were racing to add much-needed pipeline capacity out of the region, but not fast enough for producers. It was an inevitability that any pipeline expansions would instantaneously fill up. Gas production records were an almost monthly or weekly occurrence, and just as unrelenting were the takeaway constraints and pressure on the region’s supply prices. Not so today. Northeast gas production in June posted a record high, with the monthly average exceeding 31 Bcf/d for the first time. Yet, June spot prices at Dominion South, Appalachia’s representative supply hub, were the strongest they’ve been in six years relative to national benchmark Henry Hub. Why? The spate of pipeline expansions and additions in the past two years have not only caught up to production but capacity now far outpaces it, and consequently, producers now have something they haven’t had in a long time — optionality. Today, we break down how much spare capacity is available and its effect on regional pricing.
