Construction of the two wind turbines for the Dutch water board Rijn en IJssel near Duiven has been completed recently. The turbines will contribute to the water board’s ambition to become energy-neutral by 2025.
The two turbines are located on the water board’s sewage treatment site at InnoFase business park. These turbines, type E-138 EP3 E2 by Enercon, have a hub height of 130 metres, a tip height of 200 metres, and a rotor diameter of 138 metres. Each turbine has a capacity of 4.2 MW. Both turbines are equipped with trailing edge owl-wings serrarions to reduce aerodynamic noise and the aviation lighting has a dimming functionality.
Construction of the first wind turbine was completed on 30 June. The second turbine was assembled in July. What remains is the final assembly and testing phase. The wind turbines are expected to be fully operational by the end of September, beginning of October. Dutch consulting firm Pondera has been involved in the project from the beginning.
Part of the energy will be used by the sewage treatment plant to make its energy needs more sustainable. The water board has the ambition to be energy-neutral by 2025. To achieve this, it is looking to realise a mix of sustainable energy sources, including biogas, solar energy and wind energy. Besides the wind turbines near Duiven, the water board is also developing the IJsselwind Wind Farm.
