General
86 wind turbines, of which 38 on shore and 48 near shore
429 MW total capacity
Yield around 1.4 billion kWh of renewable electricity per year
Comparable to the power consumption of more than 400,000 households
Three project partners are responsible for the development, construction and management of their part of Noordoostpolder Wind Farm: NOP Agrowind (on shore), RWE (on shore) and Westermeerwind (near shore)
Koepel Windenergie Noordoostpolder represents the interests of all three project partners in the case of joint matters such as the environmental impact asssessment and permits
Employment: about 300 temporary jobs during the construction and more than 100 permanent jobs after construction in service, training and maintenance
Wind turbines
On shore
The type of wind turbine used on shore is the Enercon E-126 with a capacity of 7.5 MW
The tip height (highest point of the rotor blade) is 198.5 metres
The hub height (length of the tower to halfway along the nacelle without the rotorblades) is 135 metres
Besides concrete, the foundation consists of 66 piles of 23-30 metres in length and 181 tonnes of concrete mesh
The tower weighs 2920 tonnes, is made from concrete and consists of different ‘rings’ that are stacked; the tower has a diameter of 14.5 metres at the base and a diameter of 4.5 metres at the top
The Enercon E-126 has a total weight of 3625 tonnes
About 130 lorry trips were needed to bring all the materials for a single turbine to its location
A rotor blade has a length of 62 metres and a span of 127 metres
Near shore
The type of wind turbine used near shore is the Siemens 3.0DD-108 with a capacity of 3 MW
The tip height is 149 metres
The hub height is 95 metres
The foundation consists of a steel tubular pile with a diameter of 5 metres and a length of about 35 metres
The largest part (about 25 m) of the foundation pile was driven into the IJsselmeer lake bed
The tower weighs 252 tonnes and is an impressive 90 metres tall; the tower was transported upright in two parts on a special transport ship to the construction location
A rotor blade has a length of 54 metres and a span of more than 100 metres
The rotors were lifted up as a single unit and mounted on the nacelle
