COMMERCIAL AND INDUSTRIAL FACILITIES
Facilities such as manufacturing plants, resorts, shopping
centers, office or residential buildings, universities, data
centers and hospitals reduce operating costs and carbon
footprint simultaneously.
ELECTRIC UTILITIES
Caterpillar has led innovation to deliver stationary and
containerized gas power plants to electric utilities
and district energy facilities around the world for both
continuous grid support and peak electricity demand.
MINES
Mining operators increase mine safety and reduce
carbon emissions with coal gas, while many other mining
operations are realizing the benefits of onsite gas power
generation to support greenfield site development.
AGRICULTURE AND FOOD / BEVERAGE PROCESSING
Biogas, a useful byproduct of the anaerobic digestion
of organic waste, is created by food processors, ethanol
and biodiesel manufacturers, and farms around the
world as a renewable fuel resource for Cat
electricity generation.
LANDFILLS AND WASTEWATER TREATMENT PLANTS
Landfill and sewage gases are is generated by communities
around the world as part of sanitary process infrastructure.
Instead of destroying or flaring the methane gas produced,
communities make beneficial use of this fuel as part of a
sustainable energy program.
GREENHOUSES
In greenhouses, Cat gas generator sets simultaneously deliver
electricity for lighting or sale to the local grid, hot water for
facility heating, and carbon dioxide as an organic fertilizer for
increased crop production.

MEETING YOUR NEEDS HAS SHAPED OUR HISTORY
At Caterpillar, we understand what it takes to deliver a successful gas power generation system, and it starts with a core machine that
is designed for efficiency and reliability. Since the 1920s, Caterpillar has been designing and building engines for power production.
Although the technology has changed over the years, the philosophy hasn’t: to deliver the most reliable power generation at the lowest
possible cost of ownership and operation. Today, Caterpillar not only manufactures power generation equipment, but we also provide
customized project financing and trade solutions via Cat Financial and Cat World Trade.
THE COMPLETE SOLUTION
Caterpillar is your complete gas solutions partner. From mechanical systems such as gas fuel train and heat recovery systems, to
exhaust aftertreatment that complies with the world’s most stringent emission requirements, Cat Gas Solutions engineering works with
your local Cat dealer to deliver a complete scope of supply. Caterpillar also provides electrical systems such as master controls and
paralleling switchgear, electrical distribution switchgear and uninterruptible power supplies (UPS) that can meet either
UL or IEC requirements.
PRODUCT SUPPORT WORLDWIDE
Your gas power system is supported by our factory trained global network of Cat dealers. Therefore, you can rest assured that your
equipment will be ordered, delivered, installed and commissioned in consultation with a local expert. You’ll also have the confidence
that Caterpillar will be there to keep you up and running. Cat dealers have over 1,600 dealer branch stores operating in 200 countries
to provide the most extensive post-sales support including oil and fuel monitoring services, preventive maintenance and comprehensive
customer support agreements.
LOWER LIFE CYCLE COST
With longer maintenance intervals, higher fuel efficiency and competitive repair options, Caterpillar delivers the lowest total owning
and operating costs. When you design your facility within the Cat Application and Installation Guidelines, you can expect generator set
availability up to 99 percent of planned operating hours annually. It all adds up to a strong return on your investment, year after year.

CG260: HIGH PERFORMANCE
W
HIGHLY EFFICIENT
With recent improvements in turbocharging,
system control, and optimized pre-chamber spark
plugs, the CG260 gas generator now delivers
electrical efficiencies up to 44.1 percent.
LOWER OPERATING COSTS
Optimized engine components mean the CG260
consumes up to 30 percent less lubricating oil
than competing gas generators, which means
more money stays in your company’s pockets.
GREATER AVAILABILITY
The CG260 utilizes particle free combustion
with chamber plugs for extended maintenance
intervals and improved heat utilization. The CG260
can run on average 200 hours per year longer
than competitive systems.
SYSTEM CONTROL
Control the entire system, not just the engine,
with the Cat Total Electronic Management System.
Control or monitoring of ancillary equipment such
as heat recovery modules, exhaust aftertreatment
and fuel treatment systems becomes seamless.
Features like temperature monitoring for each
cylinder and anti-knock control allow for maximum
power output and the best possible fuel utilization,
even with fluctuating gas composition.
HIGH ALTITUDE AND
AMBIENT PERFORMANCE
The new high-boost, waste-gated A140 turbo
allows the CG260 to operate at full power up
0
C intake air, and supply stable transient load
to 45
response at higher altitudes.
