Williams Partners L.P. has placed an expansion of its Transco pipeline system into service to increase natural gas delivery capacity to New York City by 115 000 dekatherms/d in time for the 2017/2018 heating season.

The New York Bay expansion provides additional firm transportation capacity for much-needed incremental natural gas supplies to National Grid, the largest distributor of natural gas in northeastern US. The company provides service to 1.8 million customers in Brooklyn, Queens, Staten Island and Long Island.

“As we have seen with the recent storms that have devastated other states and neighbouring regions, the security of energy supply needs to be protected and enhanced. A secure and resilient supply of natural gas is critical to the local New York City and Long Island communities we serve,” said Ken Daly, President, National Grid New York. “Williams’ New York Bay expansion project will help ensure safe, reliable and secure energy to meet our customers’ needs.”


The expansion project included horsepower additions at three existing Transco compressor facilities, in addition to modifications to existing meter and regulator stations in New Jersey, Pennsylvania and New York.


“Our Transco pipeline has a long history of providing New York City with safe, reliable natural gas service,” said Micheal Dunn, Williams’ executive vice president and chief operating officer. “Our New York Bay Expansion project continues that long-standing commitment, providing additional supplies of affordable natural gas to support the region’s economic vitality and ensure a reliable energy supply to the New York City area.”

The New York Bay expansion is the fourth of Williams Partners’ projected five fully-contracted Transco expansion projects to be placed into service this year, combining with Gulf Trace, Hillabee phase one and the Dalton expansion to add more than 2.5 million dekatherms per day capacity to the Transco pipeline system so far in 2017. The partnership continues to target a 4Q17 in-service date for its fifth Transco expansion this year – the Virginia Southside II project.
