WTG is on the grid

After 10 months of construction, the wind turbine on the Schwarzenberg in Gau-Bickelheim has finally been commissioned. The Enercon E-138 turbine has a hub height of 131 meters and a total height of 200 meters. The deconstruction of access road, crane pad and assembly area has also been completed. From now on, the turbine produces clean, green electricity for the region.

Assembly of the rotor blades

Strong wind conditions during the last days made work on the WTG difficult. Finally, today the rotor blades could be assembled. Starting in the night, the rotor blades have been pulled separately from the large crane to the desired height and got then mounted to the hub. This completes the assembly of the wind turbine – at least externally.

Update assembly of main components

As planned, the main assembly started last week. First, the steel sections were assembled on top of the concrete tower. Stator and generator were then attached to the turbine nacelle and finally the hub was installed. In the next few days the rotor blades will be assembled separately. Afterwards the commissioning process will start and the turbine can be connected to the grid.

Main assembly about to start

Finally, the steel segments of the tower arrived at the site and are waiting for installation. Due to delays of the clamping works the tower segments have been temporary stored at a transfer point next to the wind farm entry point. They were brought to the site last week with a special transport vehicle. Now all components are stored right next to the site and are ready to be pre-assembled and afterwards installed, starting later this week.

Transport of large components by self-propelled transporter

Last week, the steel sections, the engine house and the rotor blades were delivered and initially stored at a transfer point. Since this week, they have been transported to the WTG site with the help of a self-propelled transporter. The self-propelled transporter can lift the entire rotor blade up to an angle of 70 degrees. In this way, the space required for transport is significantly reduced and you can navigate around curves in a confined space. Thus, no major expansion is required and the intervention in nature is minimized. Many sites can only be accessed in this way for the latest generation of rotor blades. The 4,7 km long transport of one rotor blade to the site takes just over an hour. The large components are now pre-assembled at the site. The large crane, which later lifts the components to the required height, is set up and ready to begin installation works. Due to its size and the adjacent vineyards, it was necessary to find creative solutions in order to get enough space for the crane boom.

The work on the concrete tower is finished

Concrete tower and cable constrcution works for the Schwarzenberg wind turbine have been completed. As a next step tower sections are braced to achive full stability. The lowest steel section has already been brought to the site. The delivery for the first components for the nacelle is expected from week 18 onwards. Individual parts are first stored temporarily at a logistic area and then transported to the plant as required.

Tower construction under way

Last week the trafo station was transported to the point of interconnection. At the same time construction works for the tower have begun. The separately delivered concrete parts are stored next to the crane pad and are now gradually placed on top of each other. By Easter, the concrete tower should reach its final height of 67 meters. WTG installation is expected to start in calendar week 18 with final COD in early June.

Concreting

After the Christmas break, construction works on the Schwarzenberg have started again. The preparation of the foundation works was already completed last year. Last week the coverage works of the foundation have been done. After that the foundation has been filled with concrete. Construction of the tower is planned to start in calendar week 13.

Foundation construction

Back in December 2019, works have begun at the above-ground foundation for the wind turbine on the Schwarzenberg. The preparation of the foundation reinforcement was completed last year. After the Christmas break, the external formwork will be installed in the next few days. The foundation will then be filled with concrete.

Start of construction

On Monday 14th October the construction of an Enercon E-138 wind turbine started at the Schwarzenberg site in Gau-Bickelheim (Alzey-Worms district). Currently, infrastructural works such as erection of the crane pad and road construction are taking place. In December, construction of the above-ground foundation will begin. The delivery of the main components and subsequent assembly of the wind turbines is planned for the end of March 2020. After completion, the wind turbine will have a hub height of 131 metres and a total height of 200 metres.
