Williams Transco Plans $2.1 Billion Atlantic Sunrise Expansion Project

Williams Partners’ Transco has received binding commitments for 1.7 MMDth/d of firm natural gas pipeline capacity on its proposed $2.1 billion proposed Atlantic Sunrise expansion project.This includes 15-year shipper commitments from producers, local distribution companies and power generators.

The project represents infrastructure to connect new supplies of natural gas in the Marcellus producing region in northeastern Pennsylvania with growing demand centers along the Atlantic Seaboard. Williams Partners expects to bring Atlantic Sunrise into service in the second half of 2017.

The project will consist of compression and looping of the Transco Leidy line in Pennsylvania along with a Greenfield pipeline segment, referred to as the Central Penn Line, connecting the northeastern Marcellus producing region to the Transco mainline near Station 195 in southeastern Pennsylvania. The Greenfield segment will be jointly owned by Transco and a third party.

The Atlantic Sunrise project adds to the list of Transco mainline expansions, including Leidy Southeast and Virginia Southside. Transco is pursuing expansions that between 2013 and year-end 2017 are expected to add more than 50% to its system capacity.
“We expect to invest some $5 billion over the 2013 to 2017 timeframe in Transco expansions that represent vital connections between diverse, surging supplies of domestic natural gas and growing demand centers on the Eastern Seaboard from New York City to the far Southeast,” said Alan Armstrong, president and CEO of Williams Partners.
