Customer Prioritized Reliability and Low Emissions in Choosing Capstone Technology

Capstone 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 in California, Hawaii, Nevada, Oregon, and Washington has secured an order for a 1.6 MW microturbine solution for an oil production site in Southern California. The microturbines are expected to be commissioned in the second quarter of 2023.

"Every industry has its own specialized power requirements. For energy producers, much of the available oil and gas extraction means working in remote locations in complex environments, where grid power is either unreliable or nonexistent," said Darren Jamison, Chief Executive Officer of Capstone Green Energy. "Our microturbine-based energy systems meet the needs of energy companies on every level with high power reliability, power density, low environmental impact, low noise, and minimal maintenance. It is the ideal choice for energy companies and customers across other energy-intense industries."

The new installation will feature two natural gas-fueled Capstone C800 Signature Series microturbine energy systems. It will also include a Capstone Logic Controller (CLC), which provides a single control interface and dispatch options to maximize control and efficient site operation. With their fuel flexibility, the microturbines will be configured to use the gas byproduct of the oil production as a fuel, thus reducing the need for gas flaring.

While power reliability was a critical factor in the microturbine selection, the customer was primarily interested in reducing site emissions. Not only is the microturbine technology extremely efficient, but repurposing the waste gas keeps it from entering the atmosphere, thereby reducing the emissions contributing to climate change.

"Cal Microturbine values the trust our oil and gas customers place in us to help them achieve their environmental goals while ensuring their power security needs are met," said Ryan Brown, Chief Executive Officer of Cal Microturbine.
