The Wind Energy Research Farm in Krummendeich (WiValdi) Researching future energy supplies Objective To make wind turbines quieter and more DLR research for efficient, and electricity from wind more the energy transition cost-effective. The Wind Energy Research Farm in Krummendeich (WiValdi) The plan is for 65% of Germany’s energy mix is to come from 65% renewable sources by 2030.

The extensive instrumentation provides an WiValdi is short for ‘wind validation’. excellent infrastructure for testing new technologies, such as rotor blades with new structures, shapes, WiValdi is being created by several DLR institutes and materials and designs, developed by the Wind facilities and their partners from the Research Alliance Energy Research Alliance ‘Smart Blades’ project. Wind Energy (Forschungsverbund Windenergie). Scientists from a range of disciplines will conduct Technologies from the aeronautics sector for research here. use in wind turbines can also be tested here. Examples include the use of new blade geometries for noise reduction. 1 Instrumentation WiValdi is not a conventional wind farm, as is 3 Validation clear from its meteorological masts, which are up to 150 metres tall. In addition, the wind turbine themselves are fitted with an extensive suite of sensors, while a number of measuring devices are installed on the ground. These sensor systems The research infrastructure enables a wide are the heart of the research farm. range of models to be validated. Simulations are now an indispensable part of scientific This also sets it apart from wind farms designed practice, but such models must first be verified solely for the generation of electricity. The and validated using real test cases. measurement technologies are tools for capturing all of the physical variables. How we will be keeping you up to date: DLR’s Krummendeich site WiValdi is being built on agricultural land in the joint municipality of Nordkehdingen, in the rural district of Stade, Lower Saxony, between the communities of Krummendeich, Oederquart and Freiburg (Elbe). www.windenergy-researchfarm.com Research Farm On our website you can find all important information, announcements and our construction site diary. Who we are and how to contact us The Wind Energy Research Farm in Krummendeich (WiValdi) is run by the Wind Energy Experiments facility of the German Aerospace Center (DLR) at its Krummendeich and Braunschweig sites. DLR is the Federal Republic of Germany‘s research centre for aeronautics and space. We conduct research and development activities in the fields of aeronautics, space, energy, transport, security and digitalisation. Do you have any questions about WiValdi?
