Genset Roundup

Gensets will see growth in Eastern Europe

The diesel gensets market in Eastern Europe looks set to enjoy a positive future, while the Western European counterpart, which is fairly mature market, is approaching saturation.

These are the major finding of the latest analysis of the European Diesel Genset Markets Forecasts by Frost & Sullivan. The Eastern European gensets market earned revenues of $958m in 2006 and is estimated to reach $1.2bn in 2013.

“Sound economic growth and increasing investments in infrastructure in the Eastern European countries are propelling the European gensets market forward,” says research analyst Aarthi Balachandran. “Demand for power is expected to gather pace in this region and as commercial, as well as industrial activities significantly increase, the genset market will witness growth.”

Eastern European countries are increasingly gaining significance because of the rapid development in all spheres of their economies, and the markets here hold tremendous potential for gensets, which is likely to bolster overall market performance. Hence it is important for manufacturers to clearly delineate their target markets in order to gain improved market share.

In contrast, countries in Western Europe are being branded as mature markets and are exhibiting moderate levels of growth. As a result, new opportunities for sales are hard to come by. Clearly, the diesel genset market in Europe is a complex one, as the individual constituents are in various stages on their growth curves.

“The genset market in the Western European countries is gradually approaching saturation, thus restraining growth in the overall market,” explains Balachandran. “With companies striving to gain a firm foothold in the market, genset manufacturers are witnessing price-focused competition.”

Thus, manufacturers will need to adapt their product line continuously to meet end-user needs. Another significant factor that may affect the market is the development of alternative sources of power generation, such as renewable energy, fuel cells and gas gensets that can inhibit market growth rates in the long term.

Considering the high levels of saturation of the Western European markets, genset manufacturers will benefit by focussing on niche application areas.

Cummins striving for next level

Cummins has announced continued progress toward meeting the stringent 2011 US Environmental Protection Agency Tier 4 and European Union Stage IIIB emissions regulations.

Development work has now moved from test cell research to equipment level systems integration by Cummins. Combustion simulation and prototype work began in 2005.

Cummins Particulate Filter and Selective Catalytic Reduction systems are proven aftertreatment technologies capable of meeting 2011 off-road emissions levels for engines above 100 hp (75 kW). Installation and operational aspects of these systems are currently being evaluated for off-road applications.

By 2008 Cummins will be in a position to identify which of these systems offers the best value and performance proposition for construction equipment customers.

By combining enhanced engine platforms with integrated aftertreatment systems, Cummins test cell research has achieved the 90 per cent reduction in PM (Particulate Matter) and 45 percent reduction in NOx/HC (Oxides of Nitrogen/Hydrocarbon) emissions required by the EPA across the 174 to 751 hp (130 to 560 kW) range taking effect 1/1/2011.

A year later the regulations extend down to 75 hp (56 kW) with the same PM reduction, though with less severe NOx emissions levels. The 2011 EPA and EU off-road regulations replace engine-measured emissions with tailpipe-measured emissions as a single system.

The cap fits for latest Capstone microturbines

Capstone Turbine Corporation, the world’s leading manufacturer of microturbine energy systems, has announced that its Model C65 kW MicroTurbine systems are the first microturbines to be certified by Underwriters Laboratories Inc. (UL) to the latest UL 1741 interconnection standards that became effective on 7 May, 2007.

The standard, UL 1741, Inverters, Converters, Controllers, and Interconnection Systems for use with distributed energy resources was revised on November 7, 2005 to incorporate the updated requirements of the July 2005 revision of the international standard IEEE 1547.1 Standard Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems.

In order to comply with this standard, a rigorous battery of tests was conducted to ensure that Californian-based Capstone’s inverter technology meets power quality, protective relay, lightning strike and safety requirements.

Statewide utility interconnection requirements, including California Rule 21 and New York State Public Service Commission rules, have adopted the UL 1741 standard.

The UL 1741 standard facilitates customer installation of Capstone MicroTurbines in targeted regions such as California and New York.

“I am pleased with the accomplishment our engineering team has achieved being the first microturbine manufacturer to meet the new revised requirements of the UL 1741 standard,” said Mark Gilbreth, Executive Vice President and Chief Technology Officer.

“It is important that our engineering resources are focused on initiatives that satisfy marketplace requirements in order that our products remain the most attractive technology for Capstone’s customers.”

“I am proud of this achievement to meet UL’s high testing standards. Capstone will continue to work to find ways to better enable the installation of our microturbines and increase the adoption rate of our clean and reliable distributed generation technology,” were the words of Darren Jamison, president and CEO of Capstone Turbine Corporation.

Standby power for Kuwaiti oil project

Five diesel generator sets from GE Transportation’s stationary power business will provide standby power for a Kuwait oil company. The generator sets were supplied to Petrofac International Limited of Sharjah, UAE.

The four GE 12V228 diesel gensets, each rated at 2 MW continuous, and one GE 16V228 genset rated at 2.5 MW continuous provided by Petrofac International will be used as part of a major upgrade project at the oil company’s gathering center.

According to John Manison, manager of GE Marine & Stationary Power, this project marks an expansion into the oil and gas market in the Middle East for GE’s diesel gensets. “These rugged gensets are designed with customer requirements in mind, such as operation in the harsh desert environment where many oil and gas fields are situated,” Manison added.

GE’s distribution partner, Intergen, based in Milan, Italy, packaged the generators for this project. The gensets are due to be installed at the site by the end of the second quarter 2007, with operation following in late 2007.

GE is now offering its new V250 engine series, which provides customers with increased power output, reliability, fuel-efficiency, and compliance with the United States Environmental Protection Agency Tier II emissions standards.

In marine and stationary power applications, the new 250-mm bore, 12 cylinder engine produces 4265 continuous hp/3180 kW at 1050 rpm, 4060 continuous hp/3028 kW at 1000 rpm, and 3655 continuous hp/2726 kW at 900 rpm.

While the 16V250 engine produces 5685 continuous hp/4239 kW at 1050 rpm, 5415 continuous hp/4038 kW at 1000 rpm, and 4870 continuous hp/3632 kW at 900 rpm.

GE’s V228 engines are available in 8V228, 12V228 and 16V228 configurations, for power ranges from 1400 continuous hp/1004 kW to 4500 continuous hp/3,355 kW. These four-stroke, turbo-charged and after-cooled medium-speed diesels are specially designed for demanding applications.

All GE diesels feature high-capacity turbochargers, efficient combustion systems and EFI systems, and are integrated into GE marine and stationary systems to offer high fuel and lube oil efficiency, while meeting strict emissions levels.

Extending the family

Caterpillar has grown its line of Tier 2/Stage II and Tier 3/Stage IIIA compliant diesel engines, incorporating ACERT technology for industrial and off-highway applications to include 12 models, covering the range from 62 bkW to 2700 bkW.

The ACERT technology concept revolves around precise control of the combustion cycle accomplished via a systematic approach to air management, electronics, fuel systems and combustion systems.

The primary driving force behind the technology is the requirement to meet Tier 3/Stage IIIA in the USA and Europe, and new and increasingly stringent emission standards in other areas of the world.

But equally important during the ACERT technology development process has been Caterpillar’s internal mandate to achieve this goal with no sacrifice in engine reliability or durability, while delivering improved operating economy and reduced lifecycle cost. To date, more than 15 000 engines equipped with ACERT technology have been sold by Caterpillar’s Industrial Power Systems.

Caterpillar’s also offers a two-year warranty on a global basis for its Tier 2 and Tier 3/Stage IIIA compliant industrial diesel engines with ACERT technology.

Under the terms of the new warranty, industrial engines are covered for 24 months/3000 hours, whichever comes first, and for unlimited hours for the first 12 months. A third year of warranty covers cylinder block casting, cylinder head casting, crankshaft (excluding bearings), camshaft and connecting rods.
