New regional planning strategies now being prepared by Denmark's county councils will have a decisive influence on whether or not the national goal for wind power development -- 1500 MW by 2005 -- will be reached. So says the country's wind turbine owners association which is calling for each council to set minimum standards for installed wind capacity. This model has already been successfully adopted by both Ringkøbing county council in the west of Jutland and Aarhus council in the east, says the association's Flemming Tranaes. In a communication to all county councils, the association offers help and advice "in this relatively new area of competence for county council members and their technical staff." It advises: that previous wind turbine zoning plans be re-evaluated since many include areas with insufficient wind; that rule-of-thumb legislation regarding clusters or individual units should be avoided to leave room for both kinds of development; that hub height should continue to be used as the controlling height, not blade tip height, to avoid "over dimensioned rotors in relation to tower height;" that the existing statutory instrument on noise should continue to govern wind turbine siting, not minimum distance from dwellings, since each site and turbine model are different; that six times hub height is the formula which has worked best in practice on minimum distance requirements; that the law against new building works within three kilometres of the coast does not apply to wind turbines; that allowances should be made for the exchange of old turbines with new, if this can be done "in accordance with the open landscape's interests;" that regard should be taken of tree planting plans; and that siting regulations should not apply to small wind turbines with hub heights of 18 metres or less sited close to an existing dwelling.
