The 2 Megawatt CCHP System Will Work in Parallel With the Local Utility and Produce 880 Nominal Tons of Cooling Capacity To Be Distributed Throughout Operator's Maryland Facility

Capstone Green Energy Corporation (www.CapstoneGreenEnergy.com) (NASDAQ:CGRN), a global leader in carbon reduction and on-site resilient green energy solutions, announced today it has secured a contract for two C1000S microturbines for a state-of-the-art energy system for an industrial grow operator's Maryland cultivation and processing facility.

The order, secured by E-Finity Distributed Generation (www.e-finity.com), Capstone's exclusive distributor for the Mid-Atlantic, Southeastern United States, and the Caribbean, is expected to be commissioned in the summer of 2022.

Two Capstone natural gas-fueled C1000 Signature Series microturbine energy systems will use their waste heat for two exhaust-fired absorption chillers that will produce 880 tons of chilled water to be used for space conditioning of the 90,000 square foot facility. The resilient system will be capable of islanding from the electric utility in the case of a power outage and should provide continuous operation to the grow facility.

"The combined heat and power (CHP) plant is designed to meet the facility's strict cooling demand while protecting the customer from the high operational costs of operating a chilled water plant," said Tom McGeehan, E-Finity's Vice President of Sales.

The system is expected to save the customer millions of dollars over the life of the product and to reduce emissions by over 13 million pounds of CO2 per year, which is equivalent to removing over 1,110 cars from the road.

"We continue to see an increase in project opportunities in the global industrial grow house and greenhouse industry as they are realizing maximum benefits from on-site green energy, including cost savings and increased resiliency," said Darren Jamison, Capstone Green Energy President and Chief Executive Officer. "While both of these are critical for efficient operations, our green energy systems also offer significant environmental benefits," concluded Mr. Jamison.
