DONG Energy will develop the Gode Wind 1 and 2 offshore wind farms totalling 582MW off the North Sea island of Juist, around 45km from the German coast in water depths of up to 34m.
Siemens has been awarded the contract to supply turbines for the projects, 330MW Gode Wind 1 and 252MW Gode Wind 2 projects.
Under the contract, Siemens will deliver 97 6MW wind turbines, each with a rotor diameter of 154m, and will also provide services for the turbines for a period of five years.
The company will commence offshore construction on the projects in the first half of 2015 and put them into operation in the second half of 2016.
The company has already received necessary permits from German authorities for the projects including the grid connection commitment from TenneT with a specific date for the completion.
Backed by the German Stauchungsmodell that is aimed at supporting offshore wind projects being developed before the end of 2017, the projects, which are estimated to cost around €2.2bn, will generate enough electricity to power around 600,000 German households.
DONG Energy will sell the project's output at a fixed price per kWh for the first ten years of operation and at market price thereafter.
The company claims the Gode Wind projects will increase the robustness and balance in its portfolio of offshore wind farm projects across geographies and regulatory regimes.
DONG Energy executive vice-president Samuel Leupold said the latest projects, which will be its biggest investment, will strengthen its position in the offshore wind sector.
"Being constructed in an area with good wind and soil conditions, relatively close to shore and in a cluster where we can harvest synergies from other offshore wind projects, the Gode Wind projects provide a sound business case for DONG Energy," said Leupold.
DONG Energy had purchased three offshore wind projects, Gode Wind 1, 2, and 3 totalling around 900MW from PNE Wind in August 2012.
