July 27, 2026. NW Natural, Oregon’s largest gas utility company and one of the state’s oldest businesses, recently filed its annual renewable natural gas report with the Oregon Public Utilities Commission. As part of the filing, NW Natural disclosed its 2025 renewable natural gas (RNG) purchase amount of 3.35%, marking a significant increase over 2024 volumes. The company has since secured contracts for 4% RNG in 2026 and is looking to increase its RNG percentage again in 2027.
“RNG can and will be a big part of emissions reductions efforts in Oregon,” said Chris Kroeker of NW Natural. “Even with the end of some projects, we have been able to increase our RNG volumes again this year while keeping an eye on affordability. We’re especially pleased about our first volumes purchased from an Oregon producer this year.”
NW Natural’s RNG contract volumes as a percentage of its natural gas delivery to customers is among the highest such reported levels in the U.S. As a comparison, 4% is also about the same percentage of total solar energy delivered to the Oregon electric grid in 2026 after decades of electric sector investments.
