Nordic developer OX2 has applied for an environmental permit for a vast offshore wind project in a strong-wind zone between the Swedish islands of Öland and Gotland in the Baltic Sea.

The project, called Aurora, is the second project for which the Nordic developer has sought a permit, and at about 5.5GW would be by far the largest in the Baltic and one of the biggest single offshore wind projects on the planet.

By comparison, if all of Orsted’s Hornsea projects in the North Sea end up being built, they would have a combined capacity of 7.5GW,
