Williams Partners LP said late Wednesday construction on the 1.7 Bcf/d Atlantic Sunrise pipeline project is expected to be completed in August, with full service slated to begin by the end of the month.
The 200-mile project, was approved by the Federal Energy Regulatory Commission in February 2017, began greenfield construction late last year. It would expand the Transcontinental Gas Pipe Line (Transco) system, clearing a path for constrained gas in northeast Pennsylvania to reach markets in the Mid-Atlantic and Southeast. Partial service for 550 MMcf/d started up earlier this year.
Williams expects full service to begin in August, pending “timely receipt” of remaining regulatory approvals and depending on contractor schedules to wrap up construction.
Full service was previously expected to begin this month, but the company noted earlier this year that the process to commission greenfield compression services was more complicated than that of the pipeline system. The company has also fought through legal challenges and inclement weather.
Transco has binding precedent agreements with nine shippers, with Cabot Oil & Gas Corp. (1 Bcf/d), Chief Oil & Gas LLC (420 MMcf/d) and Seneca Resources Corp. (190 MMcf/d) contracting for the highest volumes.
