Cummins Power Generation, a business unit of Cummins Inc, has launched a C3000 Series genset offering up to 3.5 MW, which it describes as the highest output for a high-speed diesel genset.

The C3000 Series incorporates the new Cummins QSK95 engine to set a new industry standard, said the firm. For multiple-set applications, the exceptionally high output of the C3000 Series is designed to increase power installation efficiency and realise higher economies of scale.

The C3000 Series genset is suited to providing critical power protection for facilities requiring high-output gensets such as data centres, hospitals and utilities, said Cummins Power Generation. For mining, oil and gas projects in remote locations, the firm expects the need for dependable microgrids generating cleaner, lower-cost power to make the C3000 Series an attractive option.

The C3000 Series genset leverages Cummins ‘Power Of One’ capability, with single-company design and manufacture of all key systems. The new QSK95 engine, alternator, controls and Tier 4 SCR after-treatment have been developed simultaneously with the C3000 to deliver a fully integrated and highly optimised genset. Performance validation work will continue during 2012, followed by a customer field tests during 2013 and 2014.

Flexible customised packaging based on standard configurations will be available with the C3000 Series. Performance can be optimised through adjusting fuel consumption, transient response and emissions reduction to suit different applications.

For power generation applications, the new QSK95 engine can deliver 3.5 MW of electricity. The 95-litre engine enables fast ramp-up to maximum power for the C3000 Series genset due to faster transient response from four compact turbochargers.

The QSK95 Modular Common-Rail System (MCRS), with up to 2200-bar high-pressure fuel injection, results in smoother, quieter and more fuel-efficient operation, said Cummins Power Generation. The impressive power density of the QSK95 is made possible with immense strength at the heart of the engine due to a hardened power cylinder and a single-piece forged-steel piston, said the firm. Increased life-to-overhaul and multiple-rebuild capability significantly lower the total life cycle cost of the engine.

Uptime availability is increased with faster servicing procedures with easy access to all cooling, oil and fuel system maintenance points. Service intervals are a minimum 500 hours, with the option of much-extended oil change intervals available.


Aggreko halts 50 MW plant in Uganda

Aggreko has triggered power rationing by halting generation at a 50 MW emergency power plant in Uganda due to a diesel shortage, the country’s power distribution company Umeme announced on 9 November.

Uganda’s power shortfall has widened to 200 MW due to the shutdown, said Florence Nsubuga, Umeme’s outage project manager, according to the Wall Street Journal.

The diesel shortage is attributed to supply disruptions along the Uganda-Kenya import route, reported the newspaper.

But the East African reported that Aggreko has stopped supplying the Uganda Electricity Transmission Company from its plant at Mutundwe until its bills are settled. The newspaper said Jacobsen Electro, the country’s other significant power supplier, was threatening similar action.

Sources at Aggreko claimed their fuel supplier Shell Uganda Ltd had ceased supply over unsettled bills, said the East African.

Aggreko’s contract to supply the Uganda grid is due to be extended until the end of the year due to delays in bringing the 250 MW Bujagali hydro plant online, said the newspaper.

Electricity demand in Uganda currently stands at about 445 MW, but supply stands at a maximum of 334 MW, according to local reports. The current shortfall has been blamed on the government’s failure to pay thermal power generators like Aggreko and Electromaxx as well as on the increase of fuel prices and the drought that affected Uganda earlier in the year.

Uganda is reported to spend at least $300 million a year to subsidise diesel-fired thermal-power plants.


Petrofac orders bespoke Finning diesel genset

Finning Power Systems (Finning) is to provide a bespoke diesel genset to Petrofac for a complex FPSO unit fire pump installation.

Finning will provide a custom-engineered, hazardous area generator package to power a submersible fire pump and motor.

The genset, comprising a Caterpillar 3512B marine engine and driving an alternator, will provide dedicated power at 6600 V to a floating production, storage and offloading (FPSO) unit off Malaysia. The genset will be deck-mounted and has to meet stringent safety and environmental requirements, including DNV Marine Classification and SOLAS safety standard.

Finning is purpose-engineering the generator to meet the customer’s exacting requirements. These include the installation of the generator within an H60 container, which is pressurised to create a safe area as the outside atmosphere could, at times, be classified as a Zone 2, temperature class T3, Gas group IIA hazardous area. The genset also has to start and stop in accordance with the NFPA20 rules for fire pumps.

Petrofac also required Finning to make modifications to optimise the cooling system for high ambient conditions and the harsh operating environment. Finning will engineer an exhaust gas cooler that limits the exhaust gas to below 200 °C and particular attention has been paid to ensuring constant power to the cooling fans. The air blast radiator, which cools both the engine and the gas cooler is located outside of the container and has six EExd fans powered by a second alternator driven from the front of the engine.

Finning is due to complete the project at the end of November 2011.

Himoisa doubles production capacity with new punching machine and panel machine in its metal treatment line

Himoisa has added two state-of-the-art machines to its production line – a punching machine and a panel machine – to double its production capacity, said the Spain-based genset manufacturer.

The new punching machine is the most advanced machine tool currently available on the market, said the firm. This equipment is key to the metal treatment process since it performs plate drilling jobs required for the assembly of various chassis components of the generator set. This machine can automatically load and unload metal plates and incorporates advanced technology enabling production to be sped up considerably.

The panel machine increases precision in the metal forming process and reduces assembly times, fully mechanising and automating this production phase. Parts enter and exit the panel machine automatically, with the personnel responsible for operating the machinery simply configuring and checking the programs they run.

“The use of state-of-the-art technology within the production process means it is absolutely essential for us to have personnel trained and qualified in the areas of engineering, computer science and digital control,” said Carlos Ibáñez, Head of Himoinsa Operations. The company says it provides its employees with all the necessary training for operating and getting the most out of the technology.

Over the course of this year, Himoinsa has put a renewal and development plan into action, manifested internally through the acquisition of technologically advanced machinery, as well as externally with the redesign of its head office facilities.

The company says it remains fully committed to the growth, renewal and future of the energy sector. By buying these last two machines, Himoisa says it now has a leading up-to-date facility from a technological, technical and engineering perspective, including the acquisition of two laser cutting machines at the start of the year.

Founded in 1982, and located in San Javier in Spain’s Murcia province, Himoisa is a multinational company specialising in the manufacture and marketing of power generation systems able to meet all the needs of those who require an energy supply that is continuous, clean, efficient and guaranteed.

Aggreko and Symbion supply Tanzania grid

Aggreko and Symbion are both now providing temporary power solutions to ease a power shortfall in drought-struck Tanzania, which relies on hydropower for about two thirds of its electricity.

Aggreko started generating 100 MW from two 50 MW power plants in Dar es Salaam on 20 October to help ease Tanzania’s power shortage, said the company.

Aggreko is ready to install other machines with a capacity to generate 50 MW, but is waiting for a response from the Tanzania Electric Supply Company (Tanesco) on whether to hire them or not, said Adam Malima, deputy minister for energy and minerals, speaking at the plants’ inauguration, according to reports in local media.

Tanecso’s deputy managing director Boniface Njombe said the company has signed a one-year contract with Tanesco for interim power generation, according to The Guardian newspaper.

Symbion power is also expected to add 60 MW to Tanzania’s grid by the end of November this year, according to the newspaper.

“The construction of the plant is expected to be completed by the end of this month,” Dodoma Symbion project manager Don Brindle told reporters at the company’s site to witness the construction and installation of the 60 MW equipment in November.

According to the Symbion official, the US-based power firm had already added 37 MW to the national grid and will now add 60 MW by the end of the month, said The Guardian

Brindle said 145 MW of Symbion equipment would arrive next month meaning there would be 242 MW produced since the company started running its Ubungo power plant, said the paper.

East Africa’s second largest economy has been plagued by frequent power-outages since December 2010. Tanesco announced daily 12-hour power cuts in June for an unspecified period because of low water levels at dams and a shortage of fuel for thermal power plants.
