Windpower Monthly rating 3.5/5

Google Translate

Our rating is based on a combination of project pipeline, political and policy support, investor confidence and structural readiness of the country in terms of grid infrastructure, permitting process and local supply chain.

Estimate of installed and operating wind power capacity based on the latest statisitics and measured against the Windpower Intelligence database.

Japan has been tipped as the next big thing in wind power, with the local wind energy association (JWPA) expecting 10GW of offshore wind by 2030.

But while the government is broadly supportive and a feed-in tariff system for renewables that has been in place since 2012 is particularly favourable for offshore wind, the country continues to be hugely reliant on nuclear energy.

Policy makers are considering simplifying the permitting process and improving grid access to boost wind-power development.

In April 2019 a law came into force allowing offshore wind farms to operate for up to 30 years. Eleven candidate zones for offshore wind-power development have been identified.

With a clear regulatory framework, a stable political and financial environment and a thirst for additional power sources, Japan could become a major offshore wind market, but significant advancements need to be made in floating foundations and network infrastructure before that can happen.
