Capstone Green Energy Secures Second Order this Year from Oil and Gas Customer in the Marcellus Shale Region in Appalachia

Order Adds to the Customer’s Extensive Fleet of Capstone Microturbines

LOS ANGELES–(BUSINESS WIRE)–$CGRN #AppalachiaPowerCapstone Green Energy Corporation (NASDAQ: CGRN), announced that E-Finity Distributed Generation, Capstone’s long-time distributor for the Mid-Atlantic, Southeastern United States, and the Caribbean, secured a follow-on order for ten Capstone C65 microturbines from a leading oil and gas producer. The systems will be deployed in the heart of the Marcellus Shale Play in Appalachia and add to an already extensive fleet of Capstone microturbine systems. The order is being commissioned this summer.

“When our customers, who rely on power in remote locations for critical operations, consistently choose to return for additional units, it serves as a testament to the positive impact of Capstone Green Energy. This degree of customer loyalty can be attributed to the dependable performance, minimal maintenance requirements, and environmentally-friendly nature of our microturbine-based solutions. We deeply value the trust and confidence that our repeat customers place in our team, technology, and partners,” said Darren Jamison, President and Chief Executive Officer of Capstone Green Energy.

The C65 microturbines, fueled by wellhead natural gas extracted directly from the pipeline, will provide primary electrical power at various wellhead sites where utility power is unavailable. Serving as the primary power source for these remote sites, the microturbines will maintain ultra-low site emissions. This leading oil and gas customer continues to select Capstones microturbines based on their proven field reliability, remote monitoring and diagnostic capabilities, and high availability with partial load redundancy. By incorporating microturbines, customers can increase on-site power production, reduce operational expenses, fortify reliability, and concurrently minimize emissions.

“Our Marcellus and Utica Shale customers have expressed great satisfaction with both the power performance and round-the-clock operational reliability provided by Team E-Finity. The fact that our key customers continue to place repeat orders is a testament to our team’s exceptional capability in delivering power precisely when and where it is needed,” said Jeff Beiter, President and Chief Executive Officer of E-Finity Distributed Generation. “These microturbine units will significantly enhance production and facilitate the efficient extraction of clean-burning, abundant natural gas from one of the world’s largest natural gas fields,” added Mr. Beiter.
