VA TECH HYDRO HAS BEEN awarded the contract to refurbish three power stations in Scotland by Scottish and Southern Energy (SSE) as part of their renewable energy programme.
The stations Gaur (7.5MW), Aigas (20MW) and Kilmorack (20MW) are located near Inverness. The modernisation will increase output at Gaur by 12% and improve efficiency at Aigas and Kilmorack by 5%.
The turnkey contracts will result in the overall modernisation of the turbine-generator sets, including replacement of the turbine runners (Francis at Gaur, Kaplan at Aigus and Kilmorack) guide vanes, governor oil plants, performance test, generator stators and new brushless exciter machines. va-tech-hydro will also renew all electrical control, protection and excitation systems, including digital governors and all medium and low voltage switchgear.
Civil works include refurbishment of main gates and valves. The power stations are due to be completed by the end of 2003.
These contracts are the first phase of a programme to refurbish SSE’s network of hydro stations and will make a considerable contribution to Scotland’s target to boost generation from renewable sources by 2010.
