Wyoming Pipeline Swaps Engines to Slash Emissions by 93 Percent
Published Date: 4/22/2025
Notice
Summary
Northwest Pipeline is upgrading its Kemmerer Compressor Station in Wyoming by swapping out old engines for a new, cleaner turbine. This $73 million project will cut harmful emissions by up to 93% without changing how much gas they deliver. If you’re interested, you’ve got until the intervention deadline to speak up or get involved!
Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Major Emissions Reductions Announced
Northwest's Modernization and Emissions Reduction (MER) Program is expected to cut nitrogen oxide (NOx) emissions by 93% and potential methane emissions by 89%. The Kemmerer Horsepower Replacement Project is part of that MER Program and replaces older compressors with a new low-emissions turbine.
No Change to Gas Delivery or Service
Northwest will abandon in place four reciprocating compressor units and one legacy gas turbine (total 13,200 ISO-rated HP / 9,637 site-rated HP) and replace them with a single Solar Mars 90 turbine-driven unit (13,220 ISO-rated HP / 8,936 site-rated HP). The reduction in site-rated horsepower at the Kemmerer Compressor Station will not affect the station's design delivery capacity or Northwest's customer service obligations.
