Since 2003 ECN is exploiting its wind turbine test facility EWTW (ECN Wind
turbine Test site Wieringermeer) in the municipality of Hollands Kroon.
The R&D wind farm consists of five Nordex N80 wind turbines with a rated capacity of
2.5 MW. The turbines have been used extensively by ECN and its international partners to
perform wind farm specific R&D programs and verify design tools.
The six prototype locations enable manufacturers to test and optimise
prototypes and execute measurement campaigns for certification purposes. Due
to the favourable wind climate, tests can be executed at all desired wind speeds
within a short period of time.
