In the United States (US), Peaks Renewables, a subsidiary of Summit Utilities Inc., focused on investing in innovative technologies and developing renewable energy projects, and Biogas Development, a developer and operator of renewable natural gas (RNG) projects, are teaming up to enhance RNG production at Biogas Development’s Hidden Hollow Energy Landfill Gas Project in Boise, Idaho.
According to a statement, Peaks Renewables is making “a preferred equity investment”, the value of which is undisclosed, to support ongoing growth and optimization at the facility, which captures and converts landfill gas (LFG) into renewable natural gas (RNG) for use across Idaho (ID) and beyond.
The investment adds to Peaks Renewables’ growing portfolio of renewable gas projects across the United States (US), reflecting the company’s “commitment to advancing reliable and renewable energy solutions through strong partnerships.”
The Boise Landfill Gas Project is a model for how public and private partnerships can drive meaningful progress toward a cleaner energy future. This investment builds on our expanding portfolio of renewable gas projects and demonstrates our commitment to transforming wasted resources into cutting-edge energy solutions that spur economic development and enhance energy reliability. We’re proud to support Biogas Development on a project that puts local waste to work—transforming it into renewable energy that fuels communities and drives resiliency, said Lizzy Reinholt, President of Peaks Renewables.
Increase RNG production
The Hidden Hollow Energy Landfill Gas Project seeks to increase its distributed energy production, reduce emissions, drive economic growth, and advance energy reliability and resiliency for Ada County and the surrounding region.
The Hidden Hollow Energy Landfill Gas Project has been producing renewable natural gas since early 2025.
The facility captures methane from decomposing waste at the Ada County Landfill and upgrades it into pipeline-quality RNG, which is injected into the regional natural gas system.
Biogas Development has been deeply committed to advancing landfill gas-to-energy solutions for nearly a decade. Our Boise landfill project is the first of its kind in Idaho. Together with Peaks, we have the opportunity to continue growing and expanding this facility—and the role of landfill gas in Idaho’s energy mix—while demonstrating how strategic collaboration and long-term investment can drive innovation, reliability, and energy independence, said Ahren Tryon, CEO of Biogas Development.
The Boise facility stands as an example of circular economy principles—turning waste into a resource while reducing carbon emissions and supporting local energy independence.
