Organic growth projects

The $335 million GTN XPress project is our largest-ever organic growth opportunity. The project includes horsepower replacement, other reliability work, and incremental compression capability at existing sites. This is expected to meet GTN customers’ needs for reliable and affordable transportation of clean-burning natural gas, consistent with the Pacific Northwest’s desire for a cleaner energy future. The project includes multiple stages, to be in service between 2021 and 2023.
