Horns Rev 3 also sets new standards for the price of renewable energy from offshore wind farms and for the size of wind turbines in Danish waters.

A wind farm for power generation, testing and training

Tjæreborg Enge Wind Farm technical description

The first of eight new turbines at Tjæreborg Enge Wind Farm was commissioned in 1996 and the last one as recently as in 2008. Tjæreborg Enge Wind Farm consists of eight wind turbines varying from 1,000 to 2,750 kW. Together they have an installed capacity of 17 MW. The hub height of the various turbines ranges from 50 to 60 m, with blade spans of 54 to 80 m.

Ryå Wind Farm characteristics

The 5 Wincon turbines have an installed capacity of 7.5 MW. 

After Vattenfall acquired Rejsby Hede Wind Farm in 2005, wind farm developments onshore have been so strong that Rejsby is now ranked third in Vattenfall's Danish portfolio of land-based wind farms. One wind power turbine has been taken out of operation since 2005 and the total capacity at Rejsby Hede is now 23.4 MW.

One of the largest onshore wind farms in Denmark

Nørrekær Enge Wind Farm characteristics

The 13 Siemens 2.3 MW wind turbines at Nørrekær Enge Wind Farm have a total capacity of 29.9 MW

Span of 48 metres

Twenty-four Neg Micon turbines owned by Vattenfall stand on the site of the former lake in the north of Denmark. The blades of the turbines, have a span of 48 metres.

The three wind turbines of the Nordjylland Wind Farm have a combined effect of 6 MW and benefit from the windy conditions of the banks of the Limfjord, which cuts across north Jutland from east to west. The three turbines generate enough power to meet the annual electricity demand of 4,400 households.

Nordjylland Wind Farm was built in 2002.

35 turbines replaced

Klim Fjordeholme characteristics

Klim Fjordeholme Wind Farm was commissioned in 1996. Vattenfall dismantled the existing 35 wind turbines on Klim Fjordholme in the early summer of 2014 and replaced them with 22 new, larger, much more efficient wind turbines, one of which is owned by Klim Vindenergi.

The 35 dismantled wind turbines were sold for recycling in Italy and Ireland, among other countries.

With a total effect of 70 MW, Klim Wind Farm is the biggest onshore wind farm in Denmark.

Horns Rev 1 technical benefits

Horns Rev 1 is one step towards achieving Vattenfall’s ambitions of multiplying wind power capacity within the next 10–15 years. The wind farm is also consistent with the Danish government’s target of increasing electricity generation by offshore wind farms.

In Norddjurs, where Hollandsbjerg Wind Farm is situated, the planning and building regulations for the local authority did, until a couple of years ago, allow for the replacement of the existing wind farm so that a few more and slightly larger wind power turbines could generate four to five times the amount of electricity. Following the removal of wind power turbine renewal from the planning and building regulations by the local authority, Vattenfall has, for now, shelved the plans to renew the farm.
