Cummins provides 24 hour service sets
A cummins diesel generator will enable Internet search company Excite to maintain 24 hour service in the face of power loss problems. Companies in Silicon Valley, USA, have become aware that there is not sufficient electricity in the US grid to drive the booming hi-tech industries. Losses of up to $1 million per hour can be caused by power blackouts.
The two 1250 kW Cummins Power sets will automatically start whenever there is a brown out, or a total power outage occurs. The two units will automatically synchronise as the PowerCommand System is installed with digital parallelling. Once all of the systems are running, the second machine can be shut down as one set is sufficient for all essential loads.
An uninterruptible power system (UPS) carries the critical load while the gensets are starting up and coming to speed and voltage.
The PowerCommand Digital Master Control monitors the process and controls system loads so that the generating sets are not overloaded during the starting and emergency operation process. Software in the PowerCommand Network will alert the network operations centre and will e-mail a notice to the manager if there are any major changes in the equipment.
Emergency backup supply from MTU
MTU is to supply eight new emergency power generator sets to the Commerzbank Service Centre in Frankfurt, Main in Germany. MTU has been contracted to plan, supply, and install the gensets which are driven by 12V 396 engines and produce a combined output of 14 100 kW.
The eight engines will supply electricity to key installations in the computer centre in the event of a mains power failure. The office complex hosts a computer centre, trading centre and offices of 4000 workstations. The contract is to cost DM8 million ($3.8 million) and will be in service by the end of 2000.
Caterpillar to supply heat and power to the Danish grid
Bramming Fjernvarme AMBA, located in Bramming, Denmark, has invested in the G16CM34 engine from Caterpillar Inc., for a cogeneration application.
The V-type engine is rated at 6100 kWm (5938 kWe) and is the first G16CM34 engine that Caterpillar has sold. The genset will be used to produce district heating for the Bramming area as well as providing electricity for the Danish grid.
It will be installed at a gas engine power station alongside three other Caterpillar engines. The engine was chosen for this cogeneration application because of its high output and strong efficiency record.
Installation of the engine began in mid-September 2000, and the engine should be fully operational by 2001 Caterpillar Motoren GmbH & Co. KG, located in Kiel, Germany, built the engine after jointly developing it with the Caterpillar Large Engine Centre in Lafayette, Ind., USA.
Bramming Fjernvarme has previously purchased other Caterpillar engines, including two G3612s and one G3616.
Caterpillar’s range of diesel and natural gas fuelled engines range in size from 10 to 22 030 bhp (7 to 16 200 bkW). The Peoria, Ill., USA-based company posted 1999 sales and revenues of $19.7 billion.
Uninterruptible telecommunication services in Korea
Dresser-Rand has been chosen to supply a standby generator set to the South Korea Telecom Company. The KG2-3E gas turbine driver package will assure uninterruptible telecommunication services in Korea in the event of a power failure.

Natural Power doubles output with 12 Cats
Natural Power, part of the ENER-G Group, has ordered 12 additional Cat generators from UK Caterpillar dealer, Finning (UK) Ltd. The deal will increase Natural Power’s current fleet of 23 generators by more than 50 per cent to a total of 35.
The 12 CAT 3516TA engines are each capable of producing up to 1040 kW of power which will increase Natural Power’s overall output from 30 MW to 60 MW. The current plant already includes ten Caterpillar generating sets, and combined with the additional 12, Caterpillar engines, will account for almost two thirds of the Natural Power fleet.
“The reliability and cost of our existing Caterpillar units have confirmed our opinion of the quality of Caterpillar engines and has convinced us that having the Cat 3516TA as the prime mover for our generators is the best option to meet our needs into the future,” commented Nick Dawber, managing director of Natural Power Ltd.
Natural Power will install the engines in its own generator packages designed and built in conjunction with its sister company, Combined Power Limited, at their Salford plant with Finning to assist with commissioning and start up on site.
Finning Power Systems supplies the complete range of Cat generation equipment and provides total power solutions for landfill gas, natural gas, diesel and combined heat and power (CHP) applications.
Natural Power is also branching out into other uses for Cat engines with projects in development for applications on natural gas and biogas.
Standby gensets for Brazilian call centre
The Sao Bernardo call centre in Brazil, which answers more than one million calls per day, has installed three Scania 440 kVA standby gensets. The facility is owned by the Spanish telecomms company Telefonica and provides operator services, telephone directory, enquires and bill checking services for the Sao Paulo area.
In the event of a mains failure, the three sets will automatically switch on within 40 s. A battery power system ensures that the centre’s computers and telephone system does not crash in this time.
The three gensets are equipped with emission control, despite the fact that Brazil dose not have any emission regulations at present. Otavio Barros of Scania points out, “Emission control regulations will come into force within the next few years, and these units are already prepared.”
New Canadian 10 MW energy plant
Toromont Industries Ltd, a Caterpillar dealership, has signed a C$30 million ($20 million) Memorandum of Agreement with the Windsor Utilities commission. The deal is for Toromont’s fully owned subsidiary, Toromont Energy, to build a new cogeneration plant which will supply hot and chilled water to the Windsor, Ontario District Energy system for the next 20 years.
Toromont Energy will engineer, construct, own and operate the energy plant. The fully developed power plant will be opened in two phases to enable it to grow on-par with the in thermal load required by the city.
“Windsor Utilities has a commitment to the development of a world class district energy system. This is key to our strategy of moving forward to deliver cost-competitive commodities to our customers while improving the environmental impacts from local generation,” says Kent Edwards, general manager of Windsor Utilities.

Standby genset installed for the Royal College of Physicians
The Royal College of Physicians has installed a Volvo Penta standby generating set to meet the college’s electrical requirements in the event of mains power failure.
The 12-litre TAMD 122 marine diesel genset was installed in the Grade 1 listed building in Regents Park, London under very stringent conditions.
The Volvo Penta generating set at the Royal College of Physicians in London, UK
Volvo Penta supplied and installed the genset, which has an output of 250 KVA with ten per cent overload. The engine’s standard water-cooled manifold and turbocharger ensured minimum heat radiation into the generating room, which is supplied by a forced inlet and extract system from some distance away. The generating set had to be completely dismantled and the components lowered down the stairwell and then rebuilt in a sound-proof room in the basement. The TAMD 122 diesel engine was specially designed to enable it to pass through a doorway that is just 850 mm wide.
It is because the facility is a Grade 1 listed building English Heritage demanded that there should be no physical alterations to the property and no sign of the new installation.
168 MW power plant extension in Bermuda
The Bermuda Electric Light Company’s (Belco) new £25 million ($40 million) extension entered full operation recently. The extension allowed Belco to replace some of its older, less efficient parts of the plant with two 14 MW medium speed diesel generators.
The Pembroke East station’s new diesel generators will bring the total capacity to 168 MW which will meet the growing demand for electricity on the island and make the Bermuda plant one of the largest diesel power stations in the world.
The medium speed generators take full advantage of the latest diesel technology to ensure less environmental impact and greater thermal efficiency. Specifications were drawn up to minimize noise and vibration levels while maximizing ambient air quality, delivering results considerably better than those associated with the existing power plant.
The extension was completed with assistance from Mott MacDonald which prepared and evaluated the tender documentation, assisted with contract negotiations and advised on contract awards. During construction Mott MacDonald also assisted with project management and provided technical assistance. Mott MacDonald assisted on a similar project this year, they helped to build the Clifton Pier 30 MW diesel extension in the Bahamas.
200 standby diesel generating sets for the UK
Cummins Diesel UK has won a £20 million ($32 million) contract from Cable & Wireless. The contract is to supply the global telecommunications company with at least 200 standby generating sets throughout its network centres around UK.
