Norwegian energy developer Deep Wind Offshore (DWO) will today unveil plans for a multi-gigawatt complex of floating wind power plants in the Baltic Sea off Sweden, highlighting the growing interest in the Scandinavian country as the European Northern seas play evolves into deeper waters.

The Oslo-based company – which counts shipping giant Knutsen OAS among its main shareholders – aims to lead off with the 1.5GW Erik Segersäll project, to be located in waters of 100-200 metres part-way between the islands of Gotland and the capital city, Stockholm, with a stepwise series of utility-scale arrays on the farther horizon for construction.
