Within the practical education of the advanced physics course eab Projektmanagement GmbH organized a practical day on 4th of July 2013 on the subject of “energy production, -use and -supply”. Students from the 11th and 12th class from the “Johann-Gottfried-Herder”-Gymnasium (high school) in Pirna as well as the 6th class from the “Clara-Zetkin-Schule” (secondary school) in Freiberg visited the building site at Rothenfurth, where the company eab Projektmanagement GmbH currently establishes two wind energy turbines.
The trip was initiated by the teachers, students and their parents in cooperation with eab Projektmanagement GmbH and was intended for supporting the students in the difficult but essential subject of their occupational orientation. On the basis of an interesting and practical experience they had the special opportunity to become acquainted very close with the different professional areas of a sustainable industry, especially wind energy, and its various possibilities.
Together with the turbine manufacturer ENERCON eab enabled a site inspection. The eab experts explained the importance of wind energy to the students together with the different criteria that must be considered in particular by the investor during the planning. At the same time technical details of the turbine as well as information about the grid connection have been given and many questions have been responded. During the on-site inspection the students could develop a feeling for the huge dimensions of a modern wind energy turbine and its challenges on logistics and installation, only the rotor blades of this turbine type have a length of 38.8 meters each and the nacelle weighs 60 tons.
Especially the physical basic principle for the use of wind energy, its transformation into electrical energy, the “transport” to the feeding point and in the grid of the local energy provider Stadtwerke Freiberg and the further distribution to the domestic homes and companies have been depicted to the students. Thus, the sometimes very theoretical training got a practical application giving a better understanding.
eab Projektmanagement GmbH currently erects two wind energy turbines of the type Enercon E-82 E2 with 98 m and 108 m hub height. Both wind energy turbines have a total rated power of 2.3 MW each. These two wind energy turbines with total building heights of 139 m and 149 m, which will feed in the grid of the local energy provider Stadtwerke Freiberg, could theoretically cover the demand of about 2,840 average households with their annual production of about 9,930,000 kWh.
