US pipeline company Williams said its Transcontinental Gas Pipe Line (Transco) interstate system delivered a record amount of natural gas in January to distribution companies, power generators and LNG exporters because of successful expansions and the trend will continue in 2019 and 2020.

Transco delivered a record 15.68 million dekatherms (MMdt) on January 21 and the new peak-day mark surpassed the previous high that was set on January 5 last year.

In addition to being a major supplier to the growing LNG export industry, Transco provides natural gas to markets in 12 Southeast and Atlantic Seaboard states, including America’s biggest metropolitan areas.

The pipeline system, extending almost 1,800 miles from South Texas to New York City, also established a new three-day market area delivery record, averaging 15.30 MMdt from January 30 to February 1, 2019.

Williams, based in Tulsa, Oklahoma, said the natural gas delivery records were the result of additional firm transportation capacity created by multiple fully-contracted Transco expansions completed in 2018 and early 2019.

The abundant US natural gas supplies are being delivered into domestic markets when required as well as to liquefaction and LNG export plants. The LNG plants are set to double in number from three operational facilities to six by the end of 2019.

Williams said its pipeline expansions included the Gulf Connector, Atlantic Sunrise and the Garden State Phase II projects.

The company said that together, these expansions added more than 2.3 MMdt of firm transportation capacity to the existing pipeline system.

Construction is expected to commence on five additional Transco projects in 2019.

These are for the Rivervale South to Market system, Hillabee Phase 2, the Northeast Supply Enhancement and the Gateway and Southeastern Trail projects, collectively creating approximately 1.15 MMdt of additional pipeline capacity in 2019 and 2020.

“The recent frigid conditions across the country are an important reminder of the vital role transmission pipelines play in delivering the natural gas necessary to keep millions of Americans safe and secure, especially during winter periods of peak demand,” said Alan Armstrong, President and Chief Executive of Williams.

“The incremental capacity from the fully-contracted Transco expansion projects placed into service in 2018 and early 2019 reflects an increase of about 16 percent in Transco’s design capacity,” he added.

“This has helped position us to meet the growing demand needs of our customers,” stated Armstrong.
