Hjuleberg wind farm

Facts about the wind farm

The wind farm comprises of twelve Siemens turbines, each with a capacity of 3 MW, and is expected to generate 98 GWh of electricity a year. This is enough electricity for more than 18,000 homes.

The total height of the turbines is 150 metres to the outermost blade tip. The diameter of the rotor is 113 metres. The turbines are direct drive, which means that there's no gearbox. Instead, the drive shaft is attached directly to the generator, which is located in the nacelle.

Hjuleberg wind farm is a joint venture between Vattenfall and Swedish banking and insurance group Skandia.

Battery plant for wind energy storage

In 2023, a battery plant for energy storage will be connected to the Hjuleberg wind farm. The batteries and associated power electronics will be housed in 56 battery modules with a total output of 30 MW and 35 MWh of energy storage capacity.

The battery plant helps to reduce electricity price spikes and maintain the balance of the electricity system, making the grid more stable. The plant will be commissioned in spring 2024.

The nature conservation area around Hjuleberg

Hjuleberg is surrounded by a large area of abandoned farm land preserved from many different periods. The area is somewhat of an agricultural heritage museum. In order not to damage any ancient heritage during construction of the wind farm, an ancient heritage inventory was drawn up for the entire area, and in some places archaeological surveys of prehistoric farm land were also carried out. Now, during the operations phase, the entire area is once again available for thebenefit of the public and the local heritage association.
