TULSA, Okla.

TULSA, Okla.--(BUSINESS WIRE)--Williams Partners L.P. (NYSE: WPZ) announced today that Northwest Pipeline has filed an application with the Federal Energy Regulatory Commission (FERC) seeking authorization for its North Seattle Lateral Upgrade project in south Snohomish County in the state of Washington.

Northwest has executed firm agreements with Puget Sound Energy (PSE) for the project to expand the delivery capabilities of Northwest Pipeline’s North Seattle Lateral, which serves PSE customers. PSE operates Washington’s largest natural gas distribution system serving nearly 800,000 gas customers in six counties.

“Our customers depend on safe, reliable and affordable natural gas service. By partnering with Williams on the North Seattle Lateral Upgrade project, we can continue to reliably serve customers in the growing areas of south Snohomish and north King counties well into the future,” said Shawnte Anderson, Puget Sound Energy’s Natural Gas project manager.

Pending all federal, state and local regulatory approvals, construction-related activities are scheduled to begin in the second quarter of 2019 and would be completed in the fourth quarter of 2019.

“Demand for natural gas in the North Seattle region and other major markets continues to grow as customers recognize its value as a clean, affordable and abundant energy source,” said Walter Bennett, senior vice president of Williams Partners’ West operating area. “The North Seattle Lateral Upgrade project will add important energy infrastructure necessary to meet the region’s growing demand for natural gas.”

Northwest, a wholly owned subsidiary of Williams Partners L.P., owns and operates an existing interstate natural gas pipeline system, extending from New Mexico’s San Juan Basin to the border of Canada in Sumas, Washington. For more than 60 years, Williams Partners’ Northwest system has been a primary artery for the transmission of natural gas to the Pacific Northwest and Intermountain Region.
