VA Tech Hydro has been awarded a turn-key refurbishment contract of the Culligran power station by Scottish & Southern Energy (SSE). The Culligran power station, which became operational in 1963, is the latest in a range of SSE hydro-electric power stations to be completely refurbished by the VA Tech Hydro and Weir Engineering Services Alliance. SSE is currently undertaking a EUR 350 million programme to improve the efficiency of its existing hydro-electric power stations. As part of this programme, VA Tech Hydro and Weir Engineering Services Alliance signed a framework agreement in 2003 with SSE to provide optimal economic and timescale solutions. The turn-key refurbishment of Culligran power station includes the installation of a new 2MW Francis runner, new generator and new main inlet valve for Unit 1. The second Unit will be installed with a new 17.3MW Deriaz runner, new main inlet valve, new hydraulic and digital governor, new brushless excitation system and new generator auxiliaries. The Culligran power station will also see the implementation of new control, protection and excitation systems, new AC & DC electrics, new pipe work, as well as substation refurbishments. The plant will be fully operational in September 2005.
