Duke Energy announced its investment in two 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 County and Person County, respectively.

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, which specializes in the design, construction and operation of biogas utilization projects, will build and operate the facilities.

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, said Phillip Grigsby, Duke Energy’s senior vice president of ventures and business development.
