PSE completes $18 million Bellevue natural gas line project

New larger capacity lines in service on Feb. 13 increase reliability and accommodate future growth

BELLEVUE, Wash. (Feb. 17, 2009) – Puget Sound Energy, on Friday, Feb. 13, placed into service a new $18 million natural gas project that involved installing a three-and-a-half mile supply pipeline in downtown Bellevue and the surrounding area. The project construction which began in July 2008 included constructing a 1.9 mile 16-inch pipeline between an existing main at 140th Avenue SE, west along Lake Hills Connector to SE 8th Street, and a 1.6 mile 12-inch pipeline that runs along several streets and ends at NE 10th Street in downtown Bellevue.

PSE installed the new natural gas pipelines to increase reliability and accommodate projected growth in Bellevue’s downtown area, as well as provide back-up for an existing six-inch natural gas pipeline that will be temporarily taken out of service in late summer 2009 during a Washington State Department of Transportation Interstate 405 construction project.

“Installing a natural gas line with larger capacity to serve downtown Bellevue and points west zoned for development is a necessary upgrade to the PSE infrastructure,” said Sue McLain, senior vice president of Operations for PSE. “With the expected growth in downtown Bellevue, our existing natural gas line would have reached capacity in three to four years. Adding additional lines now in coordination with the WSDOT construction project and the City of Bellevue is a win-win for everyone.”

Additionally, adjoining the new lines to the existing feed increases reliability of the natural gas system by creating a “loop” into East Bellevue. Should one line go out, natural gas flow from the other would replace it.

“Construction in a busy urban environment is always a challenge,” said McLain. “We thank the community and permitting jurisdictions as well as local drivers and pedestrians for their cooperation and patience throughout the project.”

Re-paving of the street is scheduled to be completed in spring 2009.
