Duke Energy Invests in Two Renewable Natural Gas Projects in North Carolina

(P&GJ) — Duke Energy has invested in two new projects to convert landfill gas from two North Carolina landfills into renewable natural gas (RNG). The two projects, named Foothills Renewables and Upper Piedmont Renewables, will be located in Caldwell and Person counties.

Renewable natural gas is derived from the methane contained in landfill gas resulting from the breakdown of organic waste, which is processed to remove contaminants in order to meet natural gas pipeline quality standards.

"Duke Energy is committed to supporting sustainable energy solutions,” Phillip Grigsby, Duke Energy's senior vice president of ventures and business development, said. “Not only will these projects bring more renewable natural gas into the market, they'll also enhance sustainability in North Carolina, ultimately benefitting both the environment and energy customers," Grigsby said.

Each project is projected to produce roughly 500,000 dekatherms (Dth) of renewable natural gas each year. The combined 1 million Dth is equivalent to the average annual natural gas usage of nearly 17,000 residential customers in North Carolina.

Both landfill projects are being developed by Evensol LLC, which develops and acquires renewable fuels-based assets in the biomass, biogas and biofuels sectors. Energyneering Solutions LLC, which specializes in the design, construction and operation of biogas utilization projects, will build and operate the facilities.

"We are very fortunate to have Duke Energy as our strategic partner in the development and ownership of these important NC-based RNG facilities," David Wentworth, president & CEO of Evensol, said. "Duke's stated commitment to sustainability is clearly evidenced by its investment in these projects, which will create real environmental benefits for the citizens of North Carolina".

While some of the RNG produced by the two projects will be transported by infrastructure owned and operated by Duke Energy's Piedmont Natural Gas unit, the RNG will be sold to third-party customers and will not be purchased or used by Duke Energy.

The landfill projects are already under construction and are expected to be operational in the fourth quarter of 2022.
