Duke Energy has signed an agreement with Carbon Cycle Energy to buy methane gas produced from swine and poultry waste and use it to generate electricity at four of its natural gas plants in North Carolina.
Duke filed with the North Carolina Utilities Commission to register the L.V. Sutton Combined Cycle Station in New Hanover County, the H.F. Lee station in Wayne County, the Dan River station in Rockingham County and the Buck station in Rowan County as new renewable energy facilities.
Those facilities are expected to help Duke comply with the state renewable energy and energy efficiency standards, according to statements released Sunday.
The four stations will combust “directed biogas” produced by Carbon Cycle Energy of Boulder, Colo. The gas would be injected into a pipeline system for Duke Energy Progress and/or Duke Energy Carolinas LLC.
Never miss a local story.
The N.C. Utilities Commission accepted Duke Energy Carolinas’ registration of the Dan River and Buck combined cycle stations as new renewable energy facilities on March 11.
Duke then filed additional information to include the contract with Carbon Cycle Energy for a renewable energy resource to be used to generate electricity at the Buck station.
A location for Carbon Cycle’s plant has not been announced.
The utility estimates it should get about 125,000 megawatt-hours of energy a year from the arrangement – enough to power about 10,000 homes for a year.
