Puget Sound Energy natural gas pipeline project
Greenwood natural gas line
Fall 2007 project completed
- The new 16"- natural gas line went into service on November 6 in the Lynnwood, Mountlake Terrace and Edmonds communities
- The new natural gas pipeline cost $13.3 million
In 2007, Puget Sound Energy installed a new 16-inch diameter natural gas line in the Lynnwood, Mountlake Terrace and Edmonds communities. The new natural gas line was sized to meet existing demand for natural gas and accommodate anticipated growth for the next 30 years.
The natural gas system previously serving South Snohomish County no longer had any excess capacity. Since natural gas service was first provided to the area, population and business growth in Snohomish County and North King County has more than tripled, placing considerable demand on PSE's natural gas system because more customers are using natural gas.

How does natural gas get to my home or business?
Natural gas is a fossil fuel composed almost entirely of methane. Interstate pipelines transport natural gas to regional utility natural gas systems, where it is metered and delivered through a network of local mains, service lines and, ultimately, to customer homes and businesses. More than one-third of all Washington state households and businesses use natural gas.
