Capstone Green Energy Receives C1000S Order in Brazil for Critical Natural Gas Infrastructure

Leading Gas Distribution Operator Selects Modular Microturbine System to Deliver Full On-Site Power at Major Compression Station

LOS ANGELES–(BUSINESS WIRE)–$CGEH #BehindTheMeter—Capstone Green Energy Holdings, Inc. (the “Company” or “Capstone”) (OTCQX: CGEH), together with its subsidiaries, a leading provider of behind-the-meter clean microturbine energy solutions for industrial and commercial operations, with solutions designed for emerging datacenter applications, today announced that it has received an order for a Capstone C1000 Signature Series microturbine from one of the largest natural gas distribution companies in Brazil. The system will provide full on-site electrical power at a major natural gas compression station, with delivery in February of 2026 and commissioning planned for Summer 2026.

Secured through Capstone’s authorized distributor in Brazil, Fluxo Soluções Integradas, the project marks the first Capstone C1000S microturbine sold in the country and the first deployment of Capstone technology by a Brazilian gas distribution company. The Capstone C1000S will supply primary power at one of the client’s large-scale compression facilities – an essential site for maintaining gas flow across multiple regions facing resiliency challenges, where a power loss could disrupt natural gas availability across several states.

Reliable On-Site Power for Mission-Critical Energy Infrastructure

“This project underscores the importance of reliable on-site power for critical energy infrastructure,” said Vince Canino, President and CEO of Capstone Green Energy. “The C1000 Signature Series microturbine is engineered for high uptime in demanding, remote environments. We’re proud to be part of a solution that strengthens Brazil’s energy infrastructure with dependable, clean power and low maintenance.”

The C1000 system provides 1MW of highly reliable, ultra-low‑emission power, designed to operate continuously with minimal service requirements. Its modular architecture allows for scalability, redundancy, and seamless integration into complex industrial operations.

The system will provide critical power to support continuous compression operations, ensuring stable natural gas transportation through a key section of Brazil’s pipeline network. By improving on-site power reliability, the project strengthens energy security for downstream customers and supports the resilience of regional infrastructure.

Capstone Green Energy’s microturbines are widely used across oil and gas, mining, utilities, and industrial manufacturing applications, offering a proven pathway to cleaner, more efficient on‑site power generation.

Modular Design and Low Maintenance Drive Customer Selection

“Initial engagement began when the customer’s maintenance team visited gas facilities in Bolivia and saw Capstone microturbines operating reliably in demanding environments,” said Rafael Amarante, Product Manager for Fluxo. “Following extensive technical evaluations and through continued collaboration with the customer’s engineering team, Capstone’s technology demonstrated clear advantages over traditional reciprocating engines, including lower maintenance requirements, high reliability with a single moving part, and the flexibility of the C1000S modular design. These benefits were key in supporting the customer’s decision to move forward with Capstone for full-site power.”

The deployment highlights Capstone’s continued expansion in Latin America and its commitment to delivering sustainable, clean, cost-effective energy solutions for customers seeking to improve resilience, reduce emissions, and lower operational risk, especially in remote operating environments.
