Duke Energy will use captured methane from swine and poultry waste
On Monday, Duke Energy announced it will work with a biogas development company to provide electricity to its eastern North Carolina customers using captured methane from swine and poultry waste.
The methane from Carbon Cycle Energy will generate renewable electricity at four of the company’s power stations.
“It is encouraging to see the technological advances that allow waste-to-energy projects in North Carolina to be done in an environmentally responsible and cost-effective manner for our customers,” said David Fountain, Duke Energy president – North Carolina.
Fountain added “The gas from this project will generate carbon neutral electricity compared to the emissions that would result if the waste was left to decay naturally.”
Under North Carolina’s Renewable Energy Portfolio Standard (REPS), Duke Energy companies must meet specific compliance targets for swine and poultry waste. The company is already buying electricity generated from other facilities in the state.
The captured methane will be treated, injected into the pipeline system and used at the following four plants:
- Buck Steam Station in Rowan County
- Dan River Steam Station in Rockingham County
- H.F. Lee Station Combined Cycle Plant in Wayne County
- Sutton Combined Cycle Plant in New Hanover County
“We are pleased Duke Energy is supportive of our facility in North Carolina,” saidJames Powell, CEO of Carbon Cycle Energy. “We still have additional work to do with licensing, local regulations and completing our organic waste supply chain. But having a confirmed buyer like Duke Energy is a major step.”
Under a 15-year term, Carbon Cycle Energy is expected to produce more than 1 million MMBtus of pipeline-quality captured methane a year. Duke Energy should yield about 125,000 megawatt-hours of renewable energy a year – enough to power about 10,000 homes for a year. The renewable energy credits (RECs) generated annually by the effort will help satisfy state mandates.
On March 18, Duke Energy filed with the North Carolina Utilities Commission (NCUC) registration statements and additional information related to the plants being designated as New Renewable Energy Facilities. Under the state’s REPS requirements, this must be done for plants that will consume and generate new renewable energy.
