Williams’ Transcontinental Gas Pipe Line (Transco) is the largest natural gas pipeline (by volume pumped) in the United States. Transco and its various branches stretch from the Texas Gulf Coast all the way to New York City. As MDN previously reported, Transco completed five important expansion projects in 2017: Gulf Trace, Hillabee Phase 1, Dalton, New York Bay, and Virginia Southside II (see Transco Pipeline Update: 5th Expansion Done, More Coming 2018). Because of those expansions, Transco flowed a record-breaking, all-time high of 15.58 million dekatherms (15.58 billion cubic feet, or Bcf) of natural gas in a single day–on Jan. 5, 2018. That’s approximately 20% of all the natural gas consumed in the entire country on that day. Amazing! Two more important expansion projects that are part of the Transco system are due to complete construction and go online in 2018: Atlantic Sunrise Pipeline and Garden State Phase II. Atlantic Sunrise will feed 1.7 Bcf/day of Marcellus Shale gas from northeastern PA into the Transco system, moving it south. As an interesting aside, Cabot Oil & Gas will provide 1 Bcf/d out of the 1.7 Bcf/d on Atlantic Sunrise when it’s completed (see FERC Approves Atlantic Sunrise Pipeline! Cabot Grabs More Capacity). Here’s the Williams statement about their recent Transco record-breaking day…
