Background

The project includes pipeline construction, a new reservoir and a compressor station.

In October 2016, Northwest Natural Gas Company received Notice to Proceed with the project from Portland General Electric Company. As of November 2018 the target in-service date for the expansion was March 2019.

The project was completed in May 2019, providing no-notice storage to Portland General Electric’s Port Westward plants to balance renewable power on the grid, responding to the peak demand and variability of wind, hydro and solar generation.
