29.7.2005: Meldung: Scottish & Southern Energy PLC develops Large Scale Hydro-electric Power Station
The new hydro-electric scheme is at Glendoe in the western end of the Monadhliath mountains, to the east of Fort Augustus in Inverness-shire. The power station itself, which will be built under ground, will be located close to
the south east corner of Loch Ness.
With an installed capacity of around 100MW (megawatts), Glendoe will be Scotland"s second largest conventional hydro-electric station and the first large-scale station to be built since 1957, when the Errochty station in Perthshire, which has a capacity of 75MW, was opened.
The power station will produce around 180 million units of green electricity ina year of average rainfall, and will be very flexible and able to help to meet major fluctuations in demand for power. When synchronised, it will be able to start generating electricity at full capacity in 30 seconds and when operating at maximum capacity, Glendoe will be able to generate enough electricity to power around 250,000 homes.
The scheme involves collecting water from around 75 square kilometres ? either directly or via 8 km of underground tunnels - in a new reservoir over 600 metres above Loch Ness. The drop from the reservoir to the turbine at the side of the loch - the "head"- is, at over 600 metres, the biggest of any hydro station in the UK. The efficiency of a hydro station increases with the size of the head, making Glendoe the most efficient hydro scheme in the country.
The new reservoir will be situated at the head of Glen Tarff and will be impounded by a dam approximately 1,000 metres long, making it the longest dam in SSE"s portfolio. The dam will be shaped to suit the topography and geology of the area and will be 35m at its highest point.
Following substantial refinements made to the scheme during the planning process, the overall cost of the project is expected to be around ?140m. Preparatory work at the site will start immediately and full construction will start in the spring of 2006. Construction itself is likely to take around three years, followed by a period of commissioning which is expected to be completed towards the end of 2008. On this basis, the new scheme is likely to be generating electricity commercially from the winter of 2008/09. Up to 400 jobs are expected to be created during the construction phase.
Ian Marchant, Chief Executive of SSE, said: "SSE has a long tradition of investment in and management of renewable energy schemes in the north of Scotland, and we will approach this development in a responsible and sensitive way, in keeping with the traditions of our predecessors in the old North of Scotland Hydro-Electric Board. Glendoe is a very significant project which will have to be managed carefully and sensitively during the demanding construction phase.
Glendoe complements our investment in refurbishing our existing hydro stations, in onshore wind energy and in biomass - as well as our interests in offshore wind, marine energy, micro generation and carbon capture. It confirms that there is much more to renewable energy than a dash for wind. As the most efficient hydro scheme in the country, it will be exceptionally flexible and will have a significant part to play in meeting peak demand for power. The Glendoe development will help keep SSE at the forefront of renewable energy developments in the UK."
