Backed by long-term shipper commitments, Atlantic Sunrise increases design capacity of the Williams’s Transco pipeline by 1.7 bcfd (about 12%) to 15.8 bcfd. Williams described the project as further strengthening and extending the Transco system’s bidirectional flow, directly connecting Marcellus gas supplies with markets as far south as Alabama.

Greenfield construction on the Pennsylvania portion of the project began in September 2017 (OGJ Online, Sept. 18, 2017). The project featured 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 is owned by WGL Midstream, Cabot Oil and Gas, and EIF Vega Midstream.
