The world's tallest wind turbine is reported to have been connected to Germany.
Max Bogl Wind's four Wind turbines form a pilot phase of a larger, renewable energy and energy storage project in geldorff, near Stuttgart.
Each wind turbine generates an average of more than 10 gigawatts per year, enough to supply about 10,000 households.
By the end of 2018, the developer wants an integrated pumped storage power station to provide an additional 70 megawatts of electricity in four hours of storage.
The purpose of this design is to allow the turbines to continue to generate electricity during periods of wind tightening or other stops during high winds.
The hub height of the wind turbine is 178 meters, and the total height from the ground to the tip is 264.5 meters.
"We are proud to have taken an important step forward in the transition to energy transformation, and this is a milestone to reduce co2 emissions," said Josef Knitl, chief executive.
