Horns Rev uses Vestas V80 2MW turbines, which have an 80m rotor diameter and 70m hub height, and weigh between 439 and 489t each. The wind farm generates enough electricity for 150,000 private homes, or nearly 2% of Denmark's total electricity consumption. It cost DKK2bn (about €270m).
The Horns Rev site stretches over 20km², with 560m between each turbine. The Vestas turbines have a cut-in wind speed of 4m/s, reaching full power at 13m/s and cutting out at 25m/s. Expected annual output is 600,000,000kWh.
Horns Rev represents the first phase of Danish efforts to produce non-polluting electricity from offshore wind turbines. The Danish government has said it would like to see the country's offshore wind turbines producing about 4,000MW of electricity by 2030. In Sweden, the government similarly hopes to increase wind power capacity significantly over the next ten to 15 years.
