Largest Natural Gas Generator Rental Fleet in North America


Investment Creates Largest Natural Gas Generator Rental Fleet in North America

HoustonAggreko, the global leader in rental power, cooling, heating and oil-free compressed air announced today that its North American business is investing more than $200 million in the latest power generation technology.  The investment in diesel and natural gas equipment will provide the best available emissions-control technology on the temporary utility market. Approximately 40 per cent of the company’s investment will be made by the end of 2010 with the remaining 60 per cent in 2011, which will create the largest rental fleet of environmentally responsible power generation equipment in North America.

“Aggreko’s customers face increasing restrictions on emissions levels to meet environmental standards," said George Walker, President, Aggreko North America. “This investment is part of our commitment to help our customers meet their emissions objectives. By expanding our fleet of EPA-certified rental generators, Aggreko will help customers maximize their productivity and avoid interruptions in their businesses while reducing their overall environmental impact.” 

The equipment being purchased by Aggreko includes more than 328 MW of low-emission, diesel and natural gas generators, featuring the latest in engine technology manufactured by Cummins Inc.

The new diesel generators offer 70 per cent lower emission levels compared to previous generations of equipment and deliver proven EPA-compliant technology. They also feature the latest in safety and environmental advantages such as extremely quiet operation and design elements that reduce the risk of fluid leakage.

With more than 300 MW of natural gas units in operation internationally, Aggreko has considerable experience providing solutions using a variety of power loads, for applications ranging from large events to baseload power generation. This is the first time that a large inventory of natural gas rental units – in a range of sizes – has been available in North America. The units can be supplied for both short- and long-term projects.

North American customers choosing natural gas units should carefully consider the potential benefits in both cost and environmental efficiency. When used for long-term, continuous operation, natural gas units have been shown to offer total cost savings of 40-45 per cent compared to diesel units, primarily due to savings in fuel. All of Aggreko’s new equipment in both diesel and natural gas technology is approved to operate 24 hours a day, seven days a week, in every state in the U.S.  The expanded fleet will be strategically located to provide prompt delivery for both emergency and pre-planned use. 

“This investment and our recently announced acquisition of Northland Power Services, which provides mobile natural gas power solutions for the oil and gas exploration and production market in the Rocky Mountain region, underscores the importance we place on our strategic partnership with our clients,” said Walker.

Previously customers only had the option of purchasing natural gas generators with a 12- to 18-month waiting period to receive the units because of limited availability. Once the purchased units arrived, they were typically needed for no more than six months.

“Now, Aggreko’s customers have a rental natural gas solution, ranging from 65 kW to 1300 kW that can be installed in a matter of days, and often in only hours,” Walker added.

“To help improve safety and operational efficiencies for optimal rental equipment performance, Aggreko’s highly skilled, specially trained employees offer tremendous added value to this investment,” he continued. “They will be instrumental in helping customers evaluate and use the technologies to solve problems and seize opportunities.”

Aggreko has a long-standing relationship with Cummins going back 40 years, and is already one of its largest users of portable generators for off-road and non-marine applications.

Aggreko will be exhibiting and participating in interviews with media at Power-Gen International, December 14-16, at the Orange County Convention Center in Orlando, Fla., booth #2459.

Aggreko provides power and temperature control solutions to customers who need them either very quickly, or for a short or indeterminate length of time. Examples would be the supply of power to an industrial site which needs to service its permanent power supply, supplying a whole city in times of power shortage, or providing a major sporting event with power and cooling systems.  We serve our customers either through our 144 service centers, which we call the Local Business, or globally through our International Power Projects business.

In the Local business, which accounts for about half of our revenues, we hire our equipment to customers, who then operate it for themselves, although we retain responsibility for servicing and maintaining it.  In the International Power Projects business, which also accounts for about half of our revenues, we operate as a power producer. We install and operate power plants and we charge our customers both for providing the generating capacity, and for the electricity we produce. We design and manufacture equipment specifically for these requirements in our factory in Dumbarton, Scotland.

Recent customers include the Beijing 2008 Olympics, the Vancouver 2010 Olympics and the power utilities in over 50 countries including the UK, France, Angola, Kenya, Indonesia, Bangladesh, Venezuela, Chile, Brazil and the USA.
