Sep 24 (Nikkei) - The Japanese government plans to submit a new law to the ordinary session of the 2018 Diet, in an effort to facilitate offshore power generation by setting out standards for operators installing wind turbines and the number of years of permitted operation.
As an island nation, Japan has many locations suitable for offshore wind power generation. Some experts estimate that offshore wind turbines can generate five times as much electricity as land-based ones. The government aims to reduce operators' risks and encourage new entries of companies by instituting the necessary laws.
The four ministries -- Economy, Trade and Industry; Land, Infrastructure and Transport; and Environment, as well as the Cabinet Office -- have started discussions, but there are still a host of issues remaining, such as rules for demolishing windmills.
According to an energy mix target for 2030 set out by the Ministry of Economy, Trade and Industry in 2015, the ministry has set a goal of boosting wind power generation about threefold to 10 million kilowatts over the 2016 level. With renewable energy mostly generated by solar power currently, the government hopes that developing laws regarding offshore wind power will help expand wind power generation in Japan.
There are two types of offshore wind turbines -- fixed and floating. Both deliver electricity to substations via submarine cables. European and other countries have already embarked on numerous offshore wind power generation projects, but there have been few in Japan.
