BayWa r.e., together with its Dutch partner GroenLeven, has successfully built its third floating solar plant in a record time of only six weeks. The Sekdoorn project in the Netherlands near the city of Zwolle has a total capacity of 14.5 MWp. This will enable almost 4,000 households to be supplied with solar power.
Due to the cutting-edge, self-designed system, the installation of almost 40.000 PV modules was done in the short time span. After the completion of the 2 MWp Weperpolder project and the larger Tynaarlo plant with a capacity of 8.4 MWp, Sekdoorn is already the third floating solar plant BayWa r.e. and its partner GroenLeven have realized in the Netherlands. BayWa r.e. is planning the construction of further floating PV projects in the country with a total output of around 100 MWp.
Floating solar plants provide a wide range of options for using economically exploited bodies of water – such as reservoirs, fish farming waters or lakes on former open-cast lignite mines – in two different ways.
In a current study, the Fraunhofer Institute for Solar Energy Research has quantified the potential for floating PV installations on decommissioned coal mining lakes at 15 GW in Germany alone. A study of the World Bank Group identified a potential for Europe of 20 GW if only 1% of the surface of man-made freshwater reservoirs will be used.
There are already support schemes in place for such installations in the Netherlands as well as in France. In Germany to date this has only been discussed on the sidelines, involving their possible integration within the announced innovation tenders for renewables and storage.
The basis for these floating installations is the mounting system developed by BayWa r.e. in partnership with Zimmermann PV-Stahlbau GmbH, which meets the highest quality requirements.
