Capstone installs 6.6MW biogas project in North Carolina

Clean tech major Capstone Green Energy Holdings has installed a 6.6-MW combined heat and power (CHP) microturbine system at a landmark renewable energy facility in North Carolina. This waste-to-energy project marks a meaningful step forward in the customer’s operational strategy by monetizing swine waste through a proprietary pyrolysis process to produce renewable biogas.

Capstone microturbines will convert this on-site biogas into 100% renewable electricity for grid export, while simultaneously delivering high-value thermal energy to support the facility’s internal operations. Capstone said that this integrated approach enhances project economics, improves energy efficiency, and creates a scalable model for recurring renewable power generation and long-term revenue growth.

The project was secured by E-Finity Distributed Generation, Capstone’s distributor for the Mid-Atlantic, Southern United States, and the Caribbean region.

The sophisticated array consisting of one Capstone C600S microturbine and six Capstone C1000S microturbines is scheduled for final commissioning in March 2026.

Innovative Circular Economy Solution

“The project represents a significant shift in agricultural waste management. By utilizing pyrolysis, a thermochemical decomposition process, the facility transforms organic swine waste into a clean-burning biogas,” said Vince Canino, President and CEO of Capstone Green Energy.

He added, “Our Signature Series microturbines are uniquely engineered to handle a wide operating window, along with variable compositions of renewable biogas – providing a resilient and low-emission alternative to traditional reciprocating engines.”

Beyond improving operational efficiency, the system serves a broader community purpose. The project was designed as an effective odor-control solution, helping reduce environmental impacts while supporting local renewable energy goals. In addition to producing renewable electricity, the facility is expected to generate Carbon Emission Reduction (CER) credits.

“Projects like this show how distributed generation can provide real operational and environmental value,” said Jeff Beiter, Founder and CEO of E-Finity Distributed Generation. “By converting agricultural waste into renewable power and usable heat, the system supports odor control, improves efficiency, and enables the generation of carbon emission reduction credits, helping align economic performance with ESG goals.”
