Two C65 kW ATEX Systems Will Provide Prime Power to an Unmanned Platform

Capstone Green Energy Corporation (NASDAQ: CGRN), a global leader in carbon reduction and on-site resilient green energy solutions, announced that Sekito, Capstone's exclusive distributor in Malaysia and Brunei, has secured an order for two 65 kW systems from a leading independent upstream oil and gas company. The microturbines will be deployed at an unmanned offshore platform on the northwest coast of Malaysia. The microturbines systems are expected to be commissioned in Fall 2023.

The latest win in Malaysia comes on the heels of Capstone's distributor Ractive Engineering in Trinidad and Tobago, who also recently secured an order for two C65 ATEX-certified microturbine systems providing a reliable power source for an unmanned gas platform located on the eastern coast of Trinidad.

"For major oil and gas companies with unique power generation requirements on offshore platforms, Capstone microturbine systems solve multiple challenges at once. Our technology operates reliably with minimal maintenance while improving energy resiliency for critical infrastructure, all while lowering the carbon footprint of these sites," said Darren Jamison, Chief Executive Officer of Capstone Green Energy. "This combination of reliability, resilience, and decarbonizing energy production is appealing to our oil and gas customers and across the various industries, as evidenced by our recent orders."

The ATEX-certified microturbines will serve as the primary power source for the unmanned drilling platform and allow the operator to increase on-platform power availability. Often used for oil and gas exploration and production, Capstone's ATEX-certified systems are designed to meet the unique requirements for offshore applications, which includes superior corrosion protection and other optional features. The new system will replace an obsolete Calnetix Power Solutions TA100 microturbine currently at the site.

The new microturbine systems will run on raw associated gas released from the wellhead, providing a highly reliable power source to the entire platform. As a result, the installation will be fully automated and operate remotely. The microturbines do not require oil or lubricants to operate, and they deliver power via state-of-the-art power electronics. This translates into higher equipment availability and longer maintenance intervals, providing a significant performance advantage when compared to traditional reciprocating engines.

"We are dedicated to finding smart, practical, and environmentally friendly ways to use energy to provide effective solutions for our customers. Our focus is on providing power generation and control systems, service, and support to our customers," said Mohd Azam, Managing Director of Sekito.
