Rolls-Royce’s first Trent 60 gas turbine electrical generating package installed in Australia has officially begun service.

The announcement was made in conjunction with the formal opening of the Tamar Valley Power Station at Bell Bay, near George Town, on the Tamar River in Tasmania. Operated by Aurora Energy (Tamar Valley) Pty Ltd (trading as AETV Power), a wholly owned subsidiary of Aurora Energy, the Trent 60 Wet Low Emissions (WLE) dual-fuel electrical generating set was ordered in 2007.

Capable of providing up to 58 MW of electrical power for back-up electricity when required, as well as peaking capacity to the Tasmanian grid, the Trent 60 package has recorded over 2000 hours of operation to date.

Tony Davis, Rolls-Royce’s regional director, said: “The first Rolls-Royce gas turbine gensets in Australia were installed in 1968 here at the Bell Bay site, so we are very pleased that the first Trent 60 is installed close by.”

Aggreko powers up decommisioning at UK’s Dungeness A

Power provider Aggreko has installed power generation equipment to a major nuclear power station decommissioning project in the UK.

The Dungeness A facility in Kent, which is operated by Magnox South Sites, ceased generating electricity at the end of 2006; this was after more than 40 years of operation, during which it typically produced 3.2bn kWh per year.

Decommissioning of the site is currently underway including preparations for the final defueling of the reactors. Aggreko specified and installed two 800 kVA generators along with a bulk fuel tank and an isolating transformer for the project. The equipment was situated next to newly upgraded and extended offices on the site perimeter road and supplied power for the required operations and maintenance work.

The Aggreko equipment was brought in to replace a smaller, existing generator. It was important that there was no interruption to the power supply while the new mains feed was installed.

Of particular concern were the harmonics, which could affect the performance of the IT equipment, so an isolating transformer was used to protect the supply.

Phil Hales, area sales manager for Aggreko, said: “While the Dungeness A site is no longer producing electricity for the region, the decommissioning project is an important one and has to be carefully monitored and managed. We were brought in to advise on requirements for the operations and maintenance offices as well as supply suitable equipment.”

Last year Aggreko won a three-year contract to supply power-generation equipment to Magnox North’s site at Wylfa on Anglesey. This was a renewal of an existing four-year arrangement for the company and was awarded following a tender process. Aggreko generators and chillers are being used to ensure stable and suitable conditions for the service teams to gain access to perform inspections and carry out maintenance as part of the station’s statutory outage.

Dungeness A is situated on a 91-hectare site on the Kent coast. Construction of the power station began in 1960 with electricity generation commencing in 1965. It was one of 11 Magnox nuclear power stations commissioned in the UK between 1956 and 1971.

Cummins Power Generation announces 2010 price increases

Cummins Power Generation has announced price increases for its commercial generator sets between 6 kW and 2500 kW.

Prices of generator sets will rise between 1.5 and 2 per cent, effective January 1, 2010. This increase is due primarily to current industry dynamics, increasing commodity prices and projected market conditions. Cummins Power Generation’s commercial generator sets are used for continuous, prime and standby power in a variety of commercial and industrial applications.

The average prices of automatic transfer switches and paralleling systems will remain flat in 2010, driven by industry dynamics and projected market conditions. Like the company’s generator sets, Cummins Power Generation’s transfer switches and paralleling systems are used for continuous, standby and prime power in a wide range of commercial and industrial applications.

The company also announced that it will keep prices of consumer generator sets flat in 2010, due to consumer industry dynamics and market conditions. Cummins Power Generation’s generator sets are employed in a wide variety of mobile commercial and portable applications.
