Capstone Green Energy to Provide 1.2 MW of Microturbine Energy Systems for Leading Manufacturer in California

Capstone Green Energy Corporation (NASDAQ: CGRN), a global leader in carbon reduction and on-site resilient green Energy as a Service (EaaS) solutions, today announced that Cal Microturbine, Capstone's exclusive distributor for California, Hawaii, Nevada, Oregon and Washington, has secured an order for two C600 Signature Series microturbines with Capstone integrated heat recovery modules (HRMs).

The order, totaling 1.2 megawatts (MWs), will be deployed to an on-site power plant for an industrial manufacturer in Southern California. The systems will be installed in a combined cooling heat and power (CCHP) application allowing the customer to reduce its reliance on the local electrical grid while saving on utility costs. The order is expected to be commissioned by Summer 2023.

“We continue to draw on our long history of advanced engineering to be a cutting-edge provider of low carbon solutions and technology through our multiple product lines, each helping different types of customers in California and around the world to meet their energy needs while boosting the reliability of their energy supply, improving the predictability of energy costs and lowering their carbon footprint,” said Darren Jamison, Chief Executive Officer of Capstone Green Energy.

Two ultra-low emission Capstone ICHP C600S microturbine-based systems will provide 1.2 MWs of clean and resilient power, resulting in increased efficiency, enabling the manufacturer to reduce its carbon footprint while increasing operational efficiencies. The microturbines will be installed in a highly-efficient trigeneration application and supply energy in three forms: electricity, heat and chilled water. The application provides the best economic value to the customer and is designed to lower energy costs, increase resiliency and reduce greenhouse gas emissions.

“Cal Microturbine is extremely excited about the piqued interest and recent influx of Capstone microturbine's we've secured this year for California businesses,” said Ryan Brown, Chief Executive Officer at Cal Microturbine. “It seems that energy savvy businesses from all industries continue to see the value of incorporating Capstone Green Energy microturbines; to provide self-sufficient, clean, reliable, and low-cost power to their operation.”

“This order launches Cal Microturbine to a combined 8,240 kW of sold Capstone units to date in calendar 2022. And we are thrilled with the opportunity to continue our pilgrimage of converting as many businesses to Capstone Green Energy microturbine systems as possible for the advancement of their companies and the planet,” concluded Brown.

After a thorough analysis comparing various distributed generation technologies, operators ultimately chose low-emission Capstone microturbines as the ideal solution for their scalability, resiliency, and ability to reduce energy costs. In addition, Capstone's microturbine technology can be deployed in a number of weeks as opposed to months or years and at a cost typically lower than the local grid.
