Tokyo Gas has acquired a 21.2% stake in the 25.2MW WindFloat Atlantic floating offshore wind farm in Portugal. It is the Japanese utility’s first direct investment in an overseas floating offshore wind project.
Ocean Winds now holds a 65.17% share in the project, while fellow shareholder Repsol holds a 13.63% stake.
WindFloat Atlantic comprises three of Vestas' V164-8.4MW turbines and is the world’s first semi-submersible floating offshore wind farm. It has been operational since 2020 and is operated by Windplus, a majority-owned subsidiary of Ocean Winds – a joint venture between Portuguese utility EDP Renewables and French counterpart Engie. It was continental Europe's first floating offshore wind project to reach full operations.
The project's turbines are installed on Principle Power’s ballasted, triangular, semi-submersible foundation. Ocean Winds and Tokyo Gas are also co–shareholders in Principle Power (36.25% and 27.5% respectively) along with Aker Offshore (36.25%).
Kimoto Kentaro, Tokyo Gas's representative CEO, said: “We are pleased to strengthen our collaborative relationship with Ocean Winds through our participation in WindFloat Atlantic. Moving forward, we will leverage the knowledge gained from this collaboration to work towards the large-scale commercialisation of floating offshore wind power in Japan.”
In Japan, Tokyo Gas is developing the 30MW Fukishima Floating project which it hopes to bring online in 2032. It is also developing 760MW of fixed-bottom offshore wind in Japanese waters, including the 600MW Chiba project off Isumi, which it is developing with Northland Power.
