One of the largest in northern Europe
The requirement for renewable energy has led to more and more wind parks in the world. According to Vattenfall, wind power will account for fourteen per cent of all electricity used in the EU by 2020. A great deal of research and development has been invested in making wind turbines more efficient.
The Jädraås wind park was opened in spring 2013 and was one of Scandinavia’s largest land-based wind parks at the time with its 66 turbines. Each turbine is just over 175 metres tall. The wind park was placed here due to the high altitude location and the good wind conditions. If you walk up to the top of Kungsberget you get a fantastic view of the park.
According to Arise, a majority owner of Jädraås wind park, the 66 turbines are estimated to produce 572 gigawatt hours per year, which equates to household electricity for 114 000 homes.
In addition to contributing to our need for renewable energy, wind power development brings employment opportunities, investment and new skills to the region. Those living in the surrounding areas may also receive “rural compensation finance” to help develop the area and attract more people to live there.
The wind turbines automatically turn towards the wind, so they work well whatever direction the wind comes from. When the wind pushes the turbine blades, they drive a rotor that is attached to a generator in the turbine. There’s a gearbox between the rotor and the generator, which increases the speed. The generator then converts the power to electricity. The electricity produced in the park is distributed to the power grid to be used by you and I. Part of the electricity is also used to produce hydrogen that you can charge your car with at hydrogen fuel charging stations in Sandviken.
It would be easy to believe that extreme winds create more effective wind power, but when the wind is at more than 25 metres per second, the turbines are switched off. The best effect is produced during moderate winds of around 12 – 14 metres per second, but turbines already start to generate electricity at 4 metres per second.
Sandviken Pure Power
When wise people from all over the world in industry, academia and the public sector interacts exciting things will happen.
Sandviken is such a place in the field of fossil-free and climate-neutral energy. Here we create, together, innovation power.
Sandviken Pure Power is an open communication concept that is administered by the Municipality of Sandviken. Here we come together, who wants to contribute in making Sweden one of the world's first fossil-free countries. It is here it happens. Right now.
