The wind farm is being erected on a reclaimed site of some 345 hectares of the Garzweiler opencast mine. This is shown as a wind concentration zone in the zoning plan of the city of Bedburg. The approved 21 wind power systems with a total capacity of 67 megawatts have been planned by RWE together with the regional cooperation partner BMR. The wind power systems of the 3.2M type with a hub height of 143 metres and a rotor diameter of 114 metres are the most powerful onshore wind power systems of Senvion.
Kai Froböse, Managing Director of Senvion Deutschland GmbH, commented: „This plant will have a total height of 200 metres. With every additional metre in height above a hub height of 100 metres we can achieve an additional energy yield of up to 1 % per metre; this is what the systems of this type have demonstrated successfully in operation so far. This height is also ideally tailored to the wind site of Königshovener Höhe.”
Construction phases at a glance:
First preparatory construction activities, such as construction of roads and crane sites, have already been started. Early in May, Senvion began the excavation and subsoil improvement measures to achieve stability for the future foundations. They are due to be installed in the second quarter of 2014, along with laying the cables. The installation of the wind power systems is due to start as early as July. As with the Titz wind farm, commissioned by RWE in 2012, the wind farm will be connected to the grid through the main substation at Jackerath in the Garzweiler opencast mine. The first twelve wind power systems are due to be commissioned in the fourth quarter of 2014.
The realisation of the second construction phase with the nine remaining systems depends on the amendments to the renewable energy act expected for this year and their potential impact on the project’s economic viability.
