Puget Sound Energy (PSE) installed a new natural gas pipeline to reinforce the supply of natural gas to customers in Redmond, Bellevue, Kirkland, Sammamish, and neighboring areas. Additional capacity was needed by November 2007 to meet winter heating demand. The new 16-inch pipeline is along 196th Ave. NE, NE 85th St. and 208th Ave. NE in Redmond.
The natural gas system in east King County is reaching capacity. The new line was needed to increase natural gas system reliability as well as accommodate continued growth in east King County and surrounding areas. PSE's natural gas system works as a large network; any main line upgrade helps stabilize the system in adjacent communities as well as the entire geographic area.

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.
