EVENSOL & Project Partners Commission North Carolina’s First Two Landfill Gas-to-Renewable Natural Gas Production Facilities

SISTERS, OR (September 6, 2023) – EVENSOL LLC, a renewable energy project developer focusing on biogas and methane mitigation, announces that it has developed two renewable natural gas (“RNG”) facilities in North Carolina that are now operational. The Foothills Renewables Project in Caldwell County, NC, and the Upper Piedmont Renewables Project in Person County, NC, convert landfill gas from Republic Services’ landfills into RNG. They make a meaningful positive environmental impact, taking a natural byproduct of waste and converting it into renewable fuel.

EVENSOL, based in Sisters, OR, and its partners invested in excess of $110 million in the combined projects. Charlotte, NC-based Duke Energy is an equity investor in the two projects. Funding also included nearly $73 million in loans guaranteed by the U.S. Department of Agriculture and arranged by Greater Commercial Lending (“GCL”).

“EVENSOL is thrilled to bring these projects online, providing a beneficial use for large volumes of landfill gas, while creating a valuable renewable energy source for the residents of North Carolina. We are grateful to all our project stakeholders, investors and lenders for their patience and support in bringing these historic facilities on-line, the first landfill gas to RNG facilities in North Carolina,” said David Wentworth, President and CEO of EVENSOL.

Both projects include the development, design, permitting, construction, commissioning and operations of a state-of-the-art RNG facility. Energyneering Solutions, LLC (“ESI”) designed, constructed and will operate the facilities. Primary project components include equipment from Air Liquide, Guild Associates, Perennial Energy, and Vilter Manufacturing.

“ESI enjoyed leveraging its many years of experience dedicated exclusively to the biogas industry to design and build these facilities. The real win for ESI and all the stakeholders involved is that ESI will also operate the facilities, relying on the intimate knowledge we have developed through their design and construction,” said Benny Benson, President of ESI.

The RNG from the facilities will provide clean transportation fuel to commercial fleet vehicles. Each project will initially produce up to 500,000 dekatherms of RNG each year. The combined 1 million Dth is equivalent to the average annual natural gas use of nearly 17,000 residential customers in North Carolina.

“We’re excited for the Foothills and Upper Piedmont projects to join our growing portfolio of renewable natural gas investments,” said Sasha Weintraub, Duke Energy senior vice president and president of Duke Energy’s natural gas business unit. “Duke Energy is committed to supporting sustainable energy solutions, and we’re proud to be an industry leader in the RNG space as we continue our journey toward a cleaner energy future.”

As a leader in the environmental services industry, Republic Services is committed to decarbonizing operations and providing low-carbon solutions to customers. These landfill RNG projects directly support Republic’s long-term sustainability goal to beneficially reuse 50% more biogas by 2030.

“At Republic Services, our vision is to partner with customers to create a more sustainable world now and for future generations,” said Republic Services Area President Shane Walker. “Through our partnership, these projects will allow us to convert landfill gas into a low-carbon fuel source that reduces greenhouse gas emissions. Projects like these are not only helping Republic Services meet our sustainability goals, but our customers’ as well.”


EVENSOL LLC was established in 2013 to create value for its partners, investors, and project counterparties through the selective acquisition and development of renewable fuels-based energy assets, with particular focus on the biomass, biogas and biofuels sectors throughout the US and abroad.

EVENSOL pursues the development and acquisition of renewable energy assets requiring special attention to technical detail, flexibility in commercial and financial contract structure, process challenges, environmental limitations, and other factors constraining investors or developers not fully integrated in the design and operations of such facilities. The EVENSOL value proposition is to selectively identify biogas assets, acquire and/or develop such projects, and aggregate them into regional operating portfolios with fully integrated internal management controls.
