Østerild Wind Turbine Test Field

Østerild Wind Turbine Test Field (alternatively Risø) is a facility managed by the DTU Risø Campus of the Technical University of Denmark (DTU) for testing of offshore wind turbines with a pinnacle height up to 330 metres (1,080 ft)[1] near Thisted-Østerild, Denmark.

[3] The international IEC 61400 standard specifies how to design and validate wind turbines to gain commercial value.

After investigating 17 areas[5] and drawing criticism,[6] the Folketing decided in June 2010 to establish a wind turbine test center at Østerild.

[9][10] The current turbines reached a height of 240 metres in 2020; the Danish wind industry would like a new site capable of turbines up to 400 metres to be developed; [8][11] at the end of 2024 Siemens Gamesa had a 170-metre tower built intended for a 21MW prototype [12] under the HIPPOW project of the EC Innovation Fund [13] New ponds and open areas have improved conditions for bats.

At the northern and the southern end of the test field, there are two 250 metre tall guyed masts equipped with lamps to warn aircraft.
