Williams Partners Begins Service on Virginia Southside II Expansion, Provides Updates on Ongoing Projects

Posted on

Williams Partners L.P. today announced it has successfully placed into service its Virginia Southside II Expansion Project, the fifth of Transco’s “Big 5” expansions (Gulf Trace, Hillabee Phase 1, Dalton, New York Bay and Virginia Southside II) to begin operations this year. Combined, these five, fully-contracted expansion projects added more than 2.8 million dekatherms per day (Dth/d) of firm transportation capacity to the Transco pipeline system in 2017, increasing Transco’s design capacity by nearly 25 percent.

“The Virginia Southside II project was placed into service on time and under budget and highlights our continued execution on growth projects,” said Alan Armstrong, chief executive officer of Williams Partners’ general partner. “The timely execution of these five projects within our original collective capital budget is further evidence of Williams Partners’ sector-leading capabilities to permit, contract and construct expansion projects that serve the growing needs of our customers and meet the investment requirements of our unitholders.”

The Virginia Southside II project expands the capacity of Williams Partners’ Transco pipeline system by 250,000 Dth/d to supply Dominion Virginia Power’s new electric generation facility in Greensville County, Virginia.

In other news, Williams Partners announced construction is continuing on schedule in Pennsylvania on the greenfield portion of the Atlantic Sunrise project. The partnership is targeting a mid-2018 in-service date for this expansion of the existing Transco natural gas pipeline, which is designed to increase deliveries by 1.7 million Dth/d as it connects abundant Marcellus gas supplies with markets in the Mid-Atlantic and Southeastern U.S.

Likewise, construction is also in progress on Phase 2 of the company’s Garden State Expansion project. After placing Phase 1 of the project in service on Sept. 9, 2017, the partnership is targeting an in-service date of second-quarter 2018 for Phase 2, which includes a new compressor station on the Transco Trenton Woodbury Lateral in Burlington County, New Jersey. When completely operational, this fully-contracted expansion project will deliver up to 180,000 Dth/d of additional natural gas capacity to New Jersey Natural Gas Company.

Also, on Nov. 21, the Federal Energy Regulatory Commission (FERC) issued a Certificate of Public Convenience and Necessity authorizing Williams Partners’ Gulf Connector Expansion project. This project is a 475,000 Dth/d expansion of the Transco pipeline system in Texas and Louisiana to connect U.S. natural gas supplies with global liquefied natural gas (LNG) markets.

Constructed in two phases, the Gulf Connector Expansion project will deliver 75,000 Dth/d of natural gas to Freeport LNG Development, L.P.’s liquefaction project and 400,000 Dth/d to Cheniere Energy’s Corpus Christi liquefaction terminal, with both phases expected to be placed in service in the first half of 2019.
