Capstone Green Energy Secures Order for Three C1000S Systems for Use in California

Three Separate Orders Illustrate Range of Applications for Capstone Microturbines

LOS ANGELES–(BUSINESS WIRE)–$CGRN #AssoicatedGasCapstone Green Energy Corporation (NASDAQ: CGRN), a global leader in carbon reduction and on-site resilient green energy solutions, announced that Cal Microturbine, Capstone’s exclusive distributor for California, Hawaii, Nevada, Oregon and Washington, secured three orders for Capstone C1000 Signature Series microturbines.

Darren Jamison, President and CEO of Capstone Green Energy, explained, “The flexibility of Capstone’s microturbines is showcased through a range of customer applications, including oil and gas production, brewery operations, and renewable natural gas processing. This is only the beginning of the technology’s potential uses, along with other applications such as hospitality and agriculture installations, and EV charging.” According to Jamison, “Customers consistently report that Capstone microturbines provide dependable power, while also helping them achieve their environmental objectives.”

One C1000 will be installed at an onshore oil and gas production site using associated gas to reduce the site’s power use from their electric utility. This will reduce the customer’s operating cost and avoid flaring otherwise unusable production byproducts. This oil and gas customer already has three other Capstone microturbines, and has placed this fourth-order because they have found that the Capstone microturbines provide the most reliable and cost-effective power generation technology they have used.

A second C1000 will be installed at a brewery and operate on digester gas produced from waste byproducts. This microturbine will replace a reciprocating engine generator that was becoming too costly to maintain and unreliable for the customer. Operating a Capstone microturbine in place of the existing generator will also help in lowering the emissions at the brewery.

The third C1000 will be installed at a landfill as part of a renewable natural gas processing facility. Operating on the landfill gas, the microturbine will provide electricity for processing equipment to convert the remaining raw landfill gas into pipeline-quality natural gas and other renewable fuels for sale to customers who want to reduce their carbon footprint.

“All three of these applications have two things in common: the Capstone C1000 microturbines provide a significant financial benefit to the facilities that will use them, and they effectively reduce greenhouse gas emissions. This is a win-win-win solution that we all need more of,” said Steve Gillette, Cal Microturbine’s Director of Sales.
