NW Natural Announces Another Year-Over-Year Increase in Renewable Natural Gas

Key Terms

renewable natural gas technical

Renewable natural gas is methane captured from organic waste—like landfills, farms, or wastewater—and cleaned to the same quality as conventional pipeline gas so it can be used for heating, electricity, or vehicle fuel. Investors care because it turns waste into a revenue-generating commodity, can qualify for carbon credits or government incentives, and can reduce a company's emissions profile, affecting long-term costs, regulatory risk, and market demand much like converting trash into sellable fuel.

rng technical

Renewable natural gas (RNG) is methane captured from organic waste sources—like landfills, farms, or wastewater—and cleaned to match the quality of conventional natural gas. For investors, RNG matters because it turns waste into a marketable, low-carbon fuel that can create new revenue streams, qualify for environmental credits, and reduce a company’s carbon footprint much like turning trash into a sellable product.

Oregon’s oldest utility continues to increase the percentage of RNG delivered to customers

PORTLAND, Ore.--(BUSINESS WIRE)-- 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.
