Construction begins on Germany's largest floating solar plant in Lusatia

Energy producer LEAG is installing Germany’s largest floating solar plant on the Ostsee lake in Cottbus. The lake, which will later cover 1,900 hectares, is being created by the mid-2020s on the site of the former Cottbus-Nord open pit mine by flooding. The work will take place on the part that is currently not yet flooded. The 29-megawatt facility will cover 16 hectares and will later generate enough electricity annually to power more than 8,000 households, according to LEAG.The innovative mooring system based on pile-driven dolphins is the technological highlight of the project. Dolphins are a proven technology for anchoring sea bridges, but this is the first time they are being used in a floating PV project. On 15-meter-long steel tubes, the solar modules will be securely anchored on the lake during and after completion of the flooding.
An ABI Mobilram TM14-17V from our rental fleet, which was used by LEAG subsidiary GMB, served as the piling rig. LEAG supplies energy for millions of households, industry and public life and is one of the largest energy companies and private sector employers in eastern Germany.
