- Utility agreed to buy biomethane from Carbon Cycle Energy
- Biogas facility is planned for eastern North Carolina
Duke Energy Corp., the largest U.S. utility owner, is planning to use methane from pig and poultry waste to generate electricity at four North Carolina plants.
The company agreed to buy methane from a biogas facility that Carbon Cycle Energy LLC plans to build in the eastern part of the state, Charlotte-based Duke said in a statement Monday. The site will convert agricultural and industrial waste into biomethane.
The deal will help Duke comply with North Carolina’s renewable energy portfolio standard that requires utilities to use power from agricultural waste.
Duke estimates the gas will produce enough electricity to power about 10,000 homes for a year. It plans to use the methane at the Buck Steam Station in Rowan County, Dan River Steam Station in Rockingham County, H.F. Lee Station Combined Cycle Plant in Wayne County and Sutton Combined Cycle Plant in New Hanover County.
Carbon Cycle, based in Boulder, Colorado, hasn’t identified the location of the facility, which will produce more than one trillion British thermal units annually. It still requires government approval.
