Puget Sound Energy natural gas pipeline project

Thurston County natural gas system improvements

Winter 2015 project updates

  • After reevaluating Thurston County's natural gas needs, we are moving forward with a revised plan consisting of a series of high pressure natural gas system improvement projects.
  • Phase 1 is anticipated to run along SR 510 in Lacey. The project is currently in permitting, and we anticipate construction will begin as early as early summer 2015.
  • We will continue to communicate our project plans as they develop.

Project overview

Puget Sound Energy is working to upgrade the natural gas system in Thurston County to increase service reliability and meet customers' current and future energy needs. Because PSE's natural gas system works as a large network, upgrades to the main line help stabilize the system in adjacent communities, as well as support our entire region.

Test your natural gas knowledge by taking this short survey

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 utilities, where it is metered and delivered through a network of local mains, service lines and, ultimately, to customers' homes and businesses. More than one-third of all Washington state households and businesses use natural gas.

Committed to keeping you informed

PSE will continue to provide updates to the community. We will notify residents and businesses near the project area when construction will occur. We aim to complete the work with as little disruption as possible.
