The construction of solar plants on rewetted peatland soils is economically stimulated by the amendment of the Renewable Energy Sources Act (EEG). So far, however, there is a lack of practical experience with peatland PV systems. The extent to which the possibility of installing peatland PV on rewetted peatland soils offers an opportunity for nature and climate protection as well as for the energy transition is to be investigated in this research project.

The aim of the research project is to create a basis for the nature conservation assessment of land suitability for peatland PV and design options for peatland PV systems in terms of nature conservation and climate protection aims, taking into account agricultural, technical, legal and socio-economic requirements.


Within the framework of the research project, a catalogue of nature conservation criteria will be developed in consultation with peatland experts. This catalogue will serve as the basis for a nationwide evaluation of previously drained and agriculturally used peatland areas in order to assess their suitability or unsuitability for the construction of PV systems in combination with rewetting. In addition, criteria for the design of peatland PV systems and investigation concepts on the effects on peatland quality from an ecological perspective are being developed. The legal and planning implementation possibilities of the developed criteria are then shown and discussed from a legal perspective. Finally, the potential socio-economic impacts on land managers are examined and recommendations for action for the assessment, the nature-compatible design and the implementation are developed and shown.
