DTU’s test centre at Østerild is at the cutting edge of both onshore and offshore testing. With its unique location close to the coast in flat terrain. The site offers a mean wind speed of 8 m/s in 100m height, which is the needed minimum for testing large wind turbines. This has allowed Østerild to become home to the largest test centre in the world. Test Centre Østerild accommodates up to a total of nine testing stands, with wind turbines of a total height of 330 meters at five of the testing stands, and 250m at the remaining four. The test centre also invites the public to follow their work: A unique on-site visitor’s centre facilitates learning and knowledge-sharing in the areas of renewable energy and wind energy welcoming up to 40,000 visitors each year.
