Horns Rev 1, built off the western coast of Jutland between 2002 and 2003, was also the first wind farm to be installed in the North Sea, the first project to use monopile foundations, and the first to feature an offshore substation.
Built by Elsam (later DONG, now Ørsted), the wind farm comprises 80 Vestas V80-2.0MW turbines.

Vattenfall acquired 60 per cent of the wind farm in 2005. Ørsted owns the remaining 40 per cent stake.
According to Vattenfall, Horns Rev 1 generates enough electricity to power around 150,000 private households in Denmark.
