FERC approves Atlantic Sunrise for full service

November 2018

Williams reported that it received final approval from the Federal Energy Regulatory Commission (FERC) and has started full service on its Atlantic Sunrise Project, adding 1.7 Bcf/d of long-awaited pipeline takeaway capacity from the Marcellus Basin and boosting design capacity of the nation’s largest-volume natural gas pipeline system by 12%.

Atlantic Sunrise increases total capacity on the Transco Pipeline to 15.8 Bcf/d while strengthening and extending its bi-directional flow, directly connecting Marcellus gas supplies with markets as far south as Alabama.

“The project is significant for Pennsylvania and natural gas-consuming markets all along the East Coast, alleviating infrastructure bottlenecks and providing millions of consumers direct access to one of the most abundant, cost-effective natural gas supply sources in the country,” said Alan Armstrong, Williams president and chief executive officer.

Greenfield construction on the Pennsylvania portion of the project began in September 2017. The project featured the installation of 186 miles of greenfield pipe, 12 miles of pipe looping, 2.5 miles of pipe replacement, two new compressor stations and compressor station modifications in five states.

The greenfield segment of the Atlantic Sunrise project, known as the Central Penn Line, is jointly owned by Transco and Meade Pipeline Co LLC (Meade). Meade is owned by WGL Midstream, Cabot Oil and Gas and EIF Vega Midstream.

Throughout the permitting and construction process, Williams said the company worked closely with permitting agencies to minimize environmental and stakeholder impacts, making modifications to more than half of the original pipeline route.
