Østerild Wind Turbine Test Field is a facility managed by the Technical University of Denmark (DTU) for testing of wind turbines with a pinnacle height up to 330 metres (1,080 ft)[1] near Thisted-Østerild, Denmark.[2]

History[edit]

The area was plagued by flying sand from about 1450, and a plantation was started from 1889 to keep the sand in check.[3]

The international IEC 61400 standard specifies how to design and validate wind turbines to gain commercial value.[4] A suitable area for testing wind turbines must have good wind, a specific surface roughness, a clear area around the site, and not be in a EU Special Protection Area. After investigating 17 areas[5] and drawing criticism,[6] the Folketing decided in June 2010 to establish a wind turbine test center at Østerild. It was inaugurated in 2012,[3] and is popular among tourists.[7] New ponds and open areas have improved conditions for bats.[8][9] The first sea eagles came to the area in 2015.[10]

Description[edit]

There are 7 test stands, and each test stand has its own meteorological mast due west. Some stands were not yet put in use in 2015.[11] In 2016, the wind turbine industry requested more stands to fulfill future test requirements.[12]

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.

The masts are situated at 57°05′13″N 8°52′50″E / 57.087056°N 8.880673°E / 57.087056; 8.880673 (Østerild Wind Turbine Test Field Lighting Mast North) and at 57°02′56″N 8°52′51″E / 57.048882°N 8.880799°E / 57.048882; 8.880799 (Østerild Wind Turbine Test Field Lighting Mast South).

An 8 MW Siemens SWT-8.0-154 was commissioned in January 2017.[13]
