The Transco pipeline delivered a record 10.83 million dekatherms of natural gas on Dec. 12 to markets between Mississippi and New York City during a recent cold snap, operator Williams Partners LP announced Friday.
That is enough natural gas to heat nearly 50 million U.S. homes, surpassing the previous record of 10.5 million dekatherms set on Feb. 17.
The 10,200-mile pipeline system also set a three-day record from Dec. 10-12, when it delivered an average of 10.47 million dekatherms a day.
“This recent record was primarily driven by increased natural gas demand for home heating by local distribution companies, along with power generation,” said Frank Ferazzi, vice president and general manager of Williams' Transco pipeline.
“As intended, the timely completions this year of two recent Transco expansion projects are helping meet growing demand in some of the fastest-growing markets in the country.”
Williams Partners put Transco's Northeast Supply Link into full service on Nov. 1, adding 250,000 dekatherms a day of firm natural gas transportation from the Marcellus Shale to nearby customers in Pennsylvania, New York and New Jersey.
Half of that capacity was brought into service three months ahead of schedule.
The Mid-South Expansion, which was put into service in June, added 225,000 dekatherms a day of transportation capacity to growing markets in the Southeast.
It serves power generators in North Carolina and Alabama, along with a local distribution company in Georgia.
Williams Partners has completed 21 growth projects on Transco since 2003, increasing the system's capacity by about 55 percent.
The company has announced plans for about $2.2 billion worth of future projects to meet demand for firm natural gas transportation capacity.
Those projects are expected to be placed into service by 2017.
Transco's current system capacity is about 10.15 million dekatherms a day, enough natural gas to serve the equivalent of more than 42 million homes.
