The Japanese government's Power Generation Cost Verification Working Group calculates the cost of generating electricity from onshore wind power at 21.6 yen/kWh in 2014 and 19.8 yen/kWh in 2020, assessing that cost reductions have not progressed. Onshore wind power is one of the main sources of renewable energy in Japan, and it is significantly important to improve its economic efficiency and to promote its full-scale introduction.
This study analyzes the cost structure of onshore wind power in Japan and discusses the potential for reducing the generation cost of onshore wind power, while evaluating recent technological trends in onshore wind turbines.
We hope this report will contribute to the development of wind power in Japan.
