Caterpillar Announces First-Ever U.S. EPA Certified Natural Gas Generator Set Capable of Quick Start and Fast Load Acceptance at 2.5 MW

For Worldwide Release: July 8, 2020 

DEERFIELD, IL – Caterpillar Inc. announced today the launch of the Cat® G3520 product line - the first-ever EPA certified natural gas generator sets on the market rated at 2.0 and 2.5 MW for use in 60 Hz power markets. Additionally, a low NOx product is available with NOx emissions down to 0.5 g/bhp-hr. The G3520 is engineered to meet a full suite of critical market standards, including quick starting and loading capability, meeting NFPA 110 Level 1 Type 10 standards as well as being UL 2200 listed.

“The large-scale standby electric power industry is seeing a turn toward natural gas generators,” says Brian George, product manager in Caterpillar’s Electric Power division. “Natural gas is the cleanest-burning hydrocarbon. It is abundant, versatile, and ideal for helping our customers in meeting their sustainability goals.”

“There isn’t another gas generator set on the market like this one,” states George. “With an updated package design, the G3520 is modeled after Caterpillar’s diesel standby product to minimize installation costs and commissioning time. A high-power density 20-cylinder engine offers market-leading load acceptance and transient response. Designed for reliability, the engine features a robust design with steel pistons and a protection monitoring system.”

The G3520 features Caterpillar’s EMCP 4 generator set control system, providing engine and generator set control, protection, and monitoring. The optional EMCP 4.4 provides the ability to parallel multiple generator sets in various gas and diesel applications. The G3520 easily integrates into building management systems, with ethernet communication capabilities inherent to the control system. The expanded set of features includes complete SR5 generators, gas train, package-mounted radiators, and simplified wiring.

“The combination of certifications and critical customer requirements addressed by this product line provides market-leading performance for the standby market at 2.5 MW power output,” George says. “This generator is built upon a robust diesel 3500 platform with a proven track record, which is critical for customers who rely on our products for resiliency of their systems”.

Ideal for emergency, legally required, or optional standby systems, the G3520 is appropriate for office buildings, data centers, retail complexes, schools, government buildings, and universities, as well as research and industrial facilities.  This product is a great fit for peak shaving or load management applications as well.

Caterpillar delivers innovative power systems engineered for exceptional durability, reliability, and value. The company offers worldwide product support, with parts and service available globally through the Cat authorized service and dealer network. In addition, dealer technicians are trained to service every aspect of Cat equipment.
