The threatened bankruptcy of German wind turbine manufacturer Tacke Windtechnik is delaying installation of Tacke wind turbines in Wisconsin. As a result, organisers of this month's EPRI-DOE Wind Turbine Verification Programme (TVP) workshop have been forced to reschedule and to move it to California. The workshop is being run by the Electric Power Research Institute, a utility organisation, and the federal Department of Energy. The delay is despite earlier statements by the Canadian manufacturing arm of Tacke, Tacke Windpower Inc, that the financial troubles in Germany would not affect its operation. Tacke Windpower, founded in 1994, supplied a 600 kW Tacke turbine to Ontario Hydro and has made several hundred blades for Tacke Windtechnik. The EPRI-DOE meeting was to have been on October 16-17 in Green Bay, Wisconsin, because of the two-turbine project in nearby Glenmore hosted by Wisconsin Public Service Corporation under the TVP programme, along with Madison Gas & Electric, Wisconsin Power & Light and Wisconsin Electric Power. The workshop is now being held on December 10-11 in Tehachapi, not far from the nearby Zond and Cannon wind test facilities. The TVP was started in 1992 to evaluate early commercial wind projects at several utility sites (Windpower Monthly, September 1997). The Wisconsin Tackes made up one of two associate projects invited to submit data to the programme.
