The Kerpen wind farm is located in Blatzheim , a district of Kerpen in North Rhine-Westphalia . At the time of its construction in 1996 it was the first wind farm in the Rhein-Erft district , a second expansion stage followed in 2000. Since the systems from the first expansion stage have meanwhile been dismantled, today (as of 2020) it consists of only two wind turbines .
location
The wind farm is located in the Im Hahn district in the city of Kerpen . The Buir district is to the southwest, Blatzheim to the southeast. The B 477 passes in the immediate vicinity to the south , some distance to the north is the Cologne – Aachen railway line and the federal motorway 4 , which was relocated to the south from 2008 to 2014 due to the expansion of the Hambach opencast mine .
history
Construction work began in August 1996, and at the end of 1996 the first five wind turbines with a total output of five megawatts went into operation. 83 investors took part in the planning and construction of the wind farm, which cost around DM 6.4 million . The operator of the systems was the company Energiekontor from Bremen , whose eighth project was the Kerpen wind farm.
The type used was the NedWind NW44 / 500 model from the Dutch manufacturer NedWind . Each of these systems had a nominal output of 500 kW with a rotor diameter of 44 m and a hub height of 65 m. In contrast to most of the installed wind turbines, they did not have a three-blade but a two-blade rotor - the manufacturer primarily relied on this design and at that time built a few other wind farms in Germany in addition to Kerpen. The systems stood along a row in the Am Heidefeldchen district between Blatzheim, Haus Dorsfeld and Haus Forst, east of the K 53 to Manheim .
Just a few years after the systems were commissioned, they proved to be prone to failure. Instead of the forecast 4.4 million kilowatts of electrical output per year (approx. 1500 households), the actual consumption at the end of 2002 was only 3 to 3.6 million kilowatts per year. Problems also arose with the system components themselves, for example with the rotor blades and the control devices. Because of the risk of breakage, all rotor blades had to be replaced afterwards.
Two more wind turbines were built around 1 km west of the existing park in 2000. The AN Bonus 1.3 MW / 62 turbines from the Danish manufacturer Bonus Energy A / S (operated in Germany together with AN Windenergie GmbH under the name AN Bonus ) each have a nominal output of 1.3 MW with a rotor diameter of 62 m and a hub height of 68 m. In contrast to the NedWind systems, they are conventional three-blade rotors (Danish concept). These systems, which went into operation in September 2000, are also operated by Energiekontor AG.
Due to the failure of the NedWind systems, the operator Energiekontor planned to replace four of the systems with three new ones in 2004. Since the wind farm is located relatively close to Nörvenich Air Base and buildings in this area are subject to height restrictions, approval by the Bundeswehr was not foreseeable - although the neighboring bonus systems have a total height of 99 m. The wind farm was therefore operated for a few years with the old systems, especially since the alternative of only replacing one of the systems with a new model also failed.
Both NedWind and Bonus are no longer represented as companies in the wind energy market - in 1998, due to economic problems, NedWind was taken over by the Danish NEG Micon A / S, which in turn merged with Vestas Wind Systems in 2004 . Bonus Energy was bought by Siemens Wind Power ( Siemens Gamesa Renewable Energy since April 2017 ) in October 2004 .
On September 30, 2013, the NedWind systems were taken off the grid and then dismantled. The two bonus systems are still in operation.
