Transco kicks off FERC review of $2.6bn Atlantic Sunrise pipeline project

Transcontinental Gas Pipe Line Co. LLC applied March 31 at the Federal Energy Regulatory Commission for a certificate of public convenience and necessity for its Atlantic Sunrise Project, which will enable Transco to provide 1,700,002 dekatherms per day (dt/day) of incremental firm transportation capacity from northern Pennsylvania in Transco’s Zone 6 to markets along the Transco pipeline system, terminating in Zone 4.

Transco requested that the commission issue a final order granting these authorizations by April 29, 2016, which will enable Transco to maintain the construction schedule required to meet the July 1, 2017, in-service date for the project.

The Atlantic Sunrise Project will provide 1,700,002 dt/day of incremental firm transportation capacity from northern Pennsylvania in Transco’s Zone 6 to Transco’s Station 85 in Alabama, including markets along the Transco pipeline system in Pennsylvania, Maryland, Virginia, North Carolina, South Carolina, Georgia, Alabama, and interconnects with existing pipelines serving the Florida market.

The project will include construction of 57.3 miles of new 30-inch-diameter greenfield pipeline (the “Central Penn Line North”) and 125.2 miles of new 42-inch-diameter greenfield pipeline (the “Central Penn Line South”), incremental facilities on Transco’s existing natural gas transmission system, and modifications to Transco’s existing natural gas transmission system to enable north-to-south flow.

Under a Construction and Ownership Agreement between Transco and Meade Pipeline Co. LLC, Transco will construct, and Transco and Meade will jointly own, the Central Penn Line North and the Central Penn Line South (collectively called the “Central Penn Line”). Transco will have rights to 100% of the pipeline capacity of the Central Penn Line under a Lease Agreement between Transco and Meade.

The project will enable Transco to provide 1,700,002 dt/day of incremental firm transportation service to these nine project shippers:

  • Anadarko Energy Services;
  • Cabot Oil & Gas;
  • Chief Oil & Gas LLC;
  • Inflection Energy LLC;
  • MMGS Inc.;
  • Seneca Resources Corp.;
  • Southern Company Services;
  • Southwestern Energy Services; and
  • WGL Midstream Inc.

Transco estimates that the proposed facilities will cost about $2.588 billion. Transco’s share of the total project cost is approximately $1.839 billion.

Consistent with the commission’s Pre-Filing process, Transco initiated an extensive public and agency outreach effort early in the planning phase of the project. In March 2014, Transco formally requested that the commission staff initiate a Pre-Filing review of the project. Since that time, Transco has met with and received input from FERC staff, federal, state, and local agencies, and the public.
