The Nysted Wind Farm (also known as Rødsand) is a Danish offshore wind farm close to the Rødsand sand bank near Lolland. Gravity base foundations are used rather than piles due to ice conditions.[3]

Rødsand I

Offshore turbine, used in Nysted Wind Farm

Rødsand I was built in 2003, with 72 turbines and a total capacity of 166 MW, and was the largest in the world until 2007.[4] Annual production is some 570 GW·h, the equivalent to the electricity consumption of 140,000 Danish homes, which could save 500,000 tonnes of CO2 emissions.[5] Turbines were installed by A2SEA.[6] It receives 45 øre per kW·h for the first 42,000 full-load hours, which is about 11 years.[7]

Rødsand I was out for 4 1⁄2 months in 2007 when the main transformer suffered a malfunction,[7] causing a production loss of 23 million DKK per month.[4]

In September 2010, DONG bought E.ON's 20% share and sold half of the entire project to pension fund PensionDanmark for 700 million kroner (€94 million / US$120 million) — almost half the DKK1,600 million cost.[1] Stadtwerke Lübeck also owns a share.[7]

As of 2013 it has an availability of 97 percent.[7]

Rødsand II

In 2010, a 207 MW extension of the existing wind farm was installed by E.ON at a stated cost of EUR450m[8] and a power purchase agreement at DKK 0.629 per kW·h (US$0.12/kW·h).[9] It was originally scheduled to be completed in 2011,[10] but installation happened faster than projected,[11] and on 15 July 2010, E.ON reported that all turbines had been installed and the majority were supplying power to the Danish grid.[12] On 3 August, E.ON reported that the wind farm was ready and went into operation, three months ahead of schedule.[13] Rødsand 2 was inaugurated on 12 October.[2]

In November 2013, local power company SEAS-NVE bought 80% of Rødsand 2 for a price of DKK 2.8 billion and thus valuating the wind farm at DKK 3.5 billion.[14]
