DTU operates two test centres for the development and trials of new wind turbines: Østerild and Høvsøre.
In February 2018, the government agreed a financial package to invest in new prototype turbines, extending the test centres each with another two test beds.
A procurement process ending in September resulted in 11 bids for the two sites, DTU said.
SGRE has been awarded two new test beds, one at Østerild and one at Høvsøre.
Envision will take the second site at Østerild, while GE Renewable Energy takes the other new space at Høvsøre.
Vestas, meanwhile, has been awarded an existing vacant stand at Høvsøre.
"All bids were highly qualified and contained relevant and exciting technological bidding on research and testing activities at the centers and we regret that we have not been able to meet all qualified applicants," DTU wind energy deputy director-general Peter Hjuler Jensen said.
The expansion will mean Østerild will have nine test stands and Høvsøre will have seven.
"It is surprising that demand has been so great. It emphasises the importance of ensuring that in Denmark there is continuous access to test places and that there are enough of them. This is a crucial element in maintaining corporate investment in Denmark," said Jan Hylleberg, CEO of the Danish Wind Industry Association.
