Norway's two Norwegian wind farms, Storheia and Roan, have been shut down for violating the rights of indigenous peoples, the Norwegian Supreme Court ruled on Monday.

Storheia is Norway's largest wind farm with a capacity of 288 megawatts and is part of the largest European onshore wind farm project.

Both parks have been in operation since 2019.

Its construction started in 2016.

The indigenous Sami people, who keep reindeer in the north of the country, had sued the owners of the wind farms.

They argued that the sound and sight of the windmills terrified the animals, endangering their traditional way of life.

In addition, they also felt that fields should not be used for these types of projects.

The judge agreed that the rights of the Sami herders were being violated.

He decided that the licenses of the parks should be revoked and that the "expropriation" should be reversed.

It is unclear what that actually means, but according to a lawyer for the Sami's this means that all 151 turbines must be demolished.

Forsen Vind, which owns Storheia, reacted with surprise to the ruling and said it was waiting for a response from the Department of Energy before taking action.

The ministry is investigating the matter.

The ruling could have an impact on later planned projects.

The shepherds' lawyer referred to other wind farms, "but this is also a relevant statement for mines or, for example, major roads".

Forsen Vind is a partnership between the Norwegian energy companies Statkraft, TrønderEnergi and Nordic Wind Power DA.

The Roan Park is owned by TrønderEnergi, Stadtwerke München and Nordic Wind Power.
