other companies continued to develop the technology through shared
best-practices and trial-and-error development. At the same time,
attempts to advance the science and understanding of the physics
relevant to wind energy design were underway in several countries.
Of particular importance was ensuring the safety of turbines as
they were deployed for use near or in residential areas. The
assurance of safety led to the notion of a certification process for
particular turbine designs. Risø
National Laboratory, which had
managed the testing and evaluation of the Gedser turbine put
back into operation in the mid-1970s and had also consulted on
the Tvind project along with DTU (the Danish Technical University),
was well positioned to take on this new role as the wind turbine
certification centre for Denmark. An addition to the developing
Danish wind energy actor-network, thus, was the development
of a test facility for small wind turbines at Risø.

north of Roskilde with direct access to Roskilde Fjord. The
two circular barns contained small nuclear reactors for
research use (Photo: Risø National Laboratory).
During the early years of the wind industry development, no
formal design or safety standards existed in Denmark. The OVE
established a wind turbine safety group at its fourth “Vindtræf ”,

specific information about the early wind turbine testing at Risø.
