About the Project

The investigation area is in the Bothnian Sea, approximately 90 kilometres off the coast of Satakunta region. The project will be located in the Finnish exclusive economic zone.

The project area is approximately 1,000 km2. There are plans to install approximately 100 wind turbines with a total maximum height of 360 meters. The installed capacity is planned to be optimized to approximately 2,000 MW, which means the project may generate up to 8–9 TWh of renewable electricity into the Finnish electricity grid.

In the future, electricity demand is estimated to increase as transportation, heating and industry are electrified. Several significant and energy intensive industrial activities are located in Satakunta, for example steel manufacturing, paper mills and process industry plants.

Wellamo is a large-scale project that has an impact on the environment of the Bothnia Sea. The construction of offshore wind power requires a two-stage environmental impact assessment procedure, during which the project’s environmental impacts are mapped and ways to mitigate them are sought.


The story behind Wellamo

Wellamo is the goddess of water, lakes and seas in Finnish mythology, and she controls the storms and waves. She is also being asked for a good catch by the fishermen.
