CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today 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.
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.
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.
