      --------------------

      In December 2002, PitchWind Systems AB (www.pitchwind.se) commissioned a wind-diesel system rated 30 kVA on Osmussaare. The wind-diesel system is the only power source on this isolated island in Estonia. The end user is the Estonian Border Guard and the project was carried out in cooperation with the local partner Empower EEE, who also supplied the tower of the wind turbine.

      PitchWind's wind turbines are especially well suited for wind-diesel applications, because of the variable speed operation and special control system. No expensive dumpload, rotary converter or custom-built diesel gensets are necessary with this concept, which was originally developed by Chalmers University of Technology. Batteries are optional. On Osmussaare it was decided to include a battery bank in the system to increase fuel savings, because of the very high cost of fuel on the island, but the system works also without the battery bank.

      The power electronics used in the project are standard industrial products made by ABB and the wind-diesel control system, based on LonWorks technology, was supplied by the ÅF Group.

      During 2003, PitchWind plans to install a similar wind-diesel system together with Empower EEE on Vaindloo, another remote Estonian island.
