OREANDA-NEWS. August 04, 2017. Natural gas infrastructure company Williams' 1.7 Bcf/d (47mn m?/d) Atlantic Sunrise pipeline in the US northeast should startup on schedule in mid-2018, provided that it can begin construction this fall.

The 183-mile (295km) project is awaiting three more permits. The pipeline, which aims to bring northeast gas production to markets in the mid-Atlantic and southeastern US, has been in the spotlight after regulatory hurdles delayed the development of similar lines.

New York state regulators stopped Williams' 628mn cf/d Constitution pipeline by denying a key water permit. The company is contesting that denial in federal court. Pipeline company Enbridge's 1.5 Bcf/d Nexus project is still awaiting approval from the US Federal Energy Regulatory Commission (FERC) and FERC has halted construction on Energy Transfer's 3.25 Bcf/d Rover project because of a drilling fluid spill.

"We are anxious to see some of these big projects come on line," Williams chief executive Alan Armstrong said during a conference call today.

Gas production growth has been stymied this year by a lack of infrastructure in the Marcellus shale in Pennsylvania and West Virginia, putting some downward pressure on prices. Discounts on the Leidy Line in Pennsylvania, which is part of Williams' Transcontinental Gas pipeline system, have averaged 98?/mmBtu against the Henry Hub in the third quarter. That compares with a 66?/mmBtu discount in the second quarter.
