The mismatch between regional spatial planning for wind power development in Germany and national eligibility criteria for feed-in tariffs—A case study in West Saxony

In future, wind power is to contribute decisively toward achieving climate policy goals. It can accomplish this, however, only if sufficient space for erecting wind turbines (WTs) is made available. In Europe we currently observe the trend that administrative landscape protection counteracts the desired development. Especially in Germany, the country that leads the world thus far in terms of installed capacity for wind power, the planning authorities are moving toward limiting locally available sites by designating so-called priority and suitability areas. These areas give the erection of WTs priority over other types of land uses but prohibit the erection of WTs outside these areas. The scale and the placement of these areas will be of great significance in future for securing wind energy supply at the regional level and thus for accomplishing national goals in climate policy. According to the regulations in the law revising the legal status of the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG, 2009), payment for wind power feed-in to the grid is granted only if, with regard to energy production, the WT to be erected yields at least 60% of a pre-defined standard performance level. With this regulation, the EEG wishes to prevent erecting WTs at locations inefficient for energy production. At the same time, however, higher standards are placed on the allocation of VE areas (priority and suitability areas) as a result. This poses the question: Does regional planning conform to such standards? With the example of the planning region West Saxony, we will evaluate the role the designation of VE areas plays in achieving Germany's wind energy ambitions. The case study reveals that the strategic search of VE areas by the regional planning authorities, involving local stakeholders and the public, hampers investment in state-of-the-art WTs as fostered by the EEG (2009). This leads us to the general conclusion that, even with a participatory design of strategic planning and a determined governmental policy, deployment of the wind resource is not a fast-selling item that in future may contribute decisively toward achieving the ambitious goals in energy and climate policy.
