The world's installed capacity of offshore wind power reached over 75 GW by the end of 2023, and is expected to increase to around 300 GW globally by 2030. In this context, from the perspective of transitioning to a decarbonized society and energy security, it is imperative for Japan to expand bottom-fixed offshore wind power generation, which has a potential of 176 GW within its territorial waters alone. Japan aims to attain the deployment target of up to 45 GW by 2040, and approximately 5 GW of power plants are expected to be in operation by 2030.
