A Tacke 300 kW is to be installed next month to power a desalination plant at Dranske on the island of Rügen, even though the new turbine model has been designed mainly for overseas markets, such as India and Brazil, where installation of the large Tacke 600 kW would be problematic. The desalination plant's control system, supplied by environment technology research company SEP of Munich, enables the installation to operate with whatever electricity wind conditions allow the turbine to supply. The water storage vessels are designed to be large enough to continue to provide supplies even when the wind stops blowing. The system is expected to more or less double the output delivered by conventional desalination plant working at a fixed power input. The Dranske plant will produce 10-15 cubic metres of badly needed water per hour, although the closure of a military marine base has alleviated pressure on the island's drinking water supply, mainly caused by the discovery of Rügen by tourists. As well as niche island markets in north west Europe, the Rügenwasser/SEP system is expected to find a market at coastal sites in the hotter parts of the world.
