Williams Cos. has completed construction of its 1.7-bcfd, 200-mile Atlantic Sunrise natural gas pipeline, which is ready to be placed into service pending final approval from the US Federal Energy Regulatory Commission. The company requested such approval Sept. 19.
Backed by long-term shipper commitments, the expansion of the existing Transco gas pipeline will connect Marcellus formation gas supplies with the US Mid-Atlantic (including Dominion Energy’s Cove Point LNG liquefaction plant) and the US Southeast.
Greenfield construction on the project’s Pennsylvania portion began in September 2017 (OGJ Online, Sept. 18, 2017). The project included two greenfield compressor stations and compressor station modifications in five states. The segment of the project known as the Central Penn Line will be jointly owned by Transco and a third party.
FERC initially authorized the project in February 2017, concluding that environmental impacts associated with it would be reduced to “less than significant levels” with the implementation of mitigation measures proposed by the company and FERC.
Atlantic Sunrise cost nearly $3 billion.
