Østerild is one of the most suitable places to test large wind turbines in Denmark. Most importantly, the test center is close to the coast with plenty of wind. To test the large wind turbines, a mean wind speed of at least 8 meters per second at 100 meters height is required.
At Testcenter Østerild, there is room to test nine wind turbines. In 2019, two new test stands have emerged, after the Government chose to expand the test center. With the expansion of the test center, it has also become possible to test higher wind turbines. Before the expansion, it was possible to test wind turbines up to 250 meters in height - measured from the ground to the top wing tip.
After the expansion, it has been possible to test offshore wind turbines up to 330 meters in 5 of the test sites.
