Concrete Towers and Substation Ready, New Construction Phase to Begin at Year-End

At Elster Wind Farm, all 16 concrete towers have been completed. The substation is also nearly finished and will soon be commissioned. In December, the delivery and assembly of additional components will begin, paving the way for the first wind turbines to be operational by spring 2025.

Another significant milestone has been achieved at the Elster Wind Farm: all 16 concrete towers are now erected. These were constructed by our partner Max Bögl, who employed innovative and sustainable concrete technology. This technology reduces CO2 emissions by up to 40% in the production of the hybrid towers, making a notable contribution to environmental protection.

Substation Ready for Grid Connection
The substation is nearly complete, with only a few finishing touches remaining, and it is set to be operational in the coming weeks. Its role is to transfer the clean, renewable energy into the grid of Mitteldeutsche Netzgesellschaft Strom mbH. Two transformers will increase the voltage from 31.5 kV from the 16 turbines to 110 kV, enabling the power to be fed into the public distribution network.

Harvest Season and Bird Protection 
While construction on-site is paused for the summer, the fields beneath our turbines are bustling with activity as it's harvest time. Agricultural tractors are hard at work, while birds watch the scene, hoping for a fruitful catch. By this time next year, our wind turbines will already be connected to the grid, transforming the late summer winds into clean electricity. Even then, birds can hunt without disturbance: thanks to a 'harvest shutdown', the turbines will be switched off whenever agricultural activity occurs nearby. This ensures that birds of prey, especially during the breeding season, can hunt freely and are effectively protected.

Construction Resumes in Autumn
Construction at the Elster Wind Farm will resume in the autumn. Initially, mowing and clearing will take place along the transport routes, as well as the preparation of roads and crane areas. In December, rotor blades, steel towers, hubs, and nacelles will be delivered. The 77.5-metre-long rotor blades are being manufactured at Siemens Gamesa in Portugal and will be shipped to Rostock. From mid-December to late February, regular heavy transport will bring them to the construction site. The steel tower segments have a shorter journey: they are being produced by SAM Stahlturm- & Apparatebau in Magdeburg and delivered directly to the site. By early January, a crane will be in place, ready to assemble the wind turbines step by step, with the first rotor expected to turn by March 2025. However, there is still much to be done until then.
