Cat's newest natural-gas generator, now available globally

Caterpillar has introduced the Cat G3520 Fast Response natural-gas generator set designed for 50 Hz applications, providing top-tier load acceptance and transient response for critical operations while utilising fuel that reduces emissions.

The Cat G3520 Fast Response generator set is well-suited for various applications, including hospitals, data centres, retail complexes, schools, government buildings, universities, and industrial and research facilities.

Now available at Cat dealers globally, this generator set offers 2.6 MW (3250 kVA) for emergency standby and demand response. It is engineered to meet the ISO8528-5 G2 standard, enabling it to start and accept load within 10 seconds from a cold start and handle a 100% block load.

New features

This new addition to Caterpillar’s lineup of natural-gas power solutions enhances their fast-response capabilities. Caterpillar also offers 60 Hz standby power nodes ranging from 750 kW to 2.5 MW, certified by the U.S. Environmental Protection Agency (EPA) for both emergency and non-emergency applications.

The Cat G3520 Fast Response features the EMCP 4 control system, which provides comprehensive control, protection, and monitoring of the engine and generator set. Its Ethernet communication capabilities ensure seamless integration with building management systems. Additional features include a gas train, package-mounted radiators, and simplified wiring for easier installation.

For superior performance, the generator set can be configured with the Cat Energy Control System (ECS), an integrated suite of scalable controllers that manage energy needs from a single generator to full-site microgrid solutions, optimising multiple power sources for resilience, emissions, and cost-efficiency.

“As our global customers look for mission-critical power that can also help meet their sustainability goals, the Cat G3520 Fast Response generator set provides a high-performance, natural-gas option that helps reduce their greenhouse gas emissions when compared with traditional backup solutions,” said Melissa Busen, vice president for Caterpillar’s Electric Power Division.
