It’s official now: Max Bögl Wind AG has built the world’s tallest wind turbine in the town of Gaildorf near Stuttgart, Germany. Featuring a hub height of 178 meters and a total height of 246.5 meters, this wind turbine has set a new world record. The turbine is also part of a wholly unique power plant concept – the water battery.

More height, efficiency and power: That is the aspiration behind Max Bögl Wind AG and their hybrid towers for wind power plants. The pioneering spirit of this Bavarian company is now in full view in the town of Gaildorf near Stuttgart, home of the world’s tallest onshore wind turbine. Located in the Limpurg Hills with a hub height of 178 meters and a total height of 246.5 meters, this wind turbine is a clear sign that Max Bögl Wind AG is pushing the boundaries when it comes to harvesting wind energy. This height record was achieved in part due to the natural water reservoir built into the turbine. The wind farm in Gaildorf is not just any wind farm, but one based on a totally new power plant concept – the water battery – a technological innovation that is setting new industry standards. For the first time ever, power generation from renewable energy is combined with a modern pumped-storage power plant. This new storage concept utilizes the foundation of the wind turbine as a water reservoir, which results in a 40 meter increase in the height of the turbine. This is hugely beneficial since each additional meter of hub height added to a wind turbine increases the annual energy yield by 0.5 to 1 percent. High hub heights mean less wind turbulence and significantly better wind yield, especially for inland locations with weak wind conditions.

The world’s tallest wind turbine is part of a wind farm that consists of four wind turbines with hub heights ranging from 155 to 178 meters. Equipped with powerful 3.4 megawatt (MW) generators from GE, they will begin supplying clean energy to the German power grid in spring 2018. “Our 3MW category platform is extremely flexible and optimized for high energy yield. We are very happy that our customized solution for the GE 3.4-137 has helped to achieve this record,” says Andreas von Bobart, General Manager of GE Renewable Energy Onshore Wind Deutschland. It is estimated that more than 10 gigawatt hours will be generated per year, which is enough electricity to power 2,500 four-person households. Max Bögl Wind AG is thus playing its part in making sure the energy transition succeeds. After all, the stated goal of the German federal government is to increase the share of renewable energy sources for power generation to 50 percent. It currently lies at 38 percent. “Without large-scale and forward-looking projects and ideas, the energy transition in Germany cannot succeed. With the water battery and hybrid towers, we are making wind energy a more attractive and efficient source of clean energy while also setting new records,” remarks Josef Knitl, Board Member at Max Bögl Wind AG.

The mayor of Gaildorf, Frank Zimmermann, also adds: “In our town and throughout the region, we are investing in our common future in a very ambitious yet sensible way. Thanks to the innovative power plant concept, we are proud to be at the forefront of the energy transition – one of the most important transitions of our age.”

Innovative power sources and storage options are indispensable for the energy transition

The foundations of the wind turbine towers in Gaildorf are water reservoirs with a storage capacity of 70 megawatt hours (MWh). A penstock connects them with a hydroelectric power station and its lower reservoir located 200 meters deeper into the valley. The water battery, which was also referred to as natural power storage in the Gaildorf pilot project, can store surplus power from the grid and release it when necessary. It acts as a short-term storage facility and helps to maintain grid stability while guaranteeing a continuous, uninterrupted supply of power. The pumped-storage plant is able to switch between production and storage within 30 seconds.

About Max Bögl Wind AG
Using renewable energies more efficiently and forwarding the energy transition. This is the principle behind Max Bögl Wind AG with its innovative technology solutions. The company is the market leader in Germany for manufacturing, delivery and erection of hybrid towers for hub heights of 130 meters and above, and holds the record for the highest wind turbine tower with a hub height of 178 meters. Max Bögl Wind AG is also setting new innovative standards in the energy storage industry. With the water battery, an entirely new type of flexible and small pumped-storage power plant has been developed which for the first time combines renewable energies with large-scale storage facilities. Max Bögl Wind AG is an affiliate company of Max Bögl. The corporate group from Sengenthal near Neumarkt in Bavaria is one of the top ten largest German companies in the construction industry, and has been operating in the wind sector since 2010. Founded in 1929, the family-owned company with around 6,000 employees worldwide has an annual turnover of over 1.6 billion euros.
