Feed-in Tariffs in Japan: Five Years of Achievements and Future Challenges

Renewable Energy Institute today released the full English translated version of the report "Feed-in Tariffs in Japan: Five Years of Achievements and Future Challenges". The original Japanese version of the report was released on 10 August 2017.

By the end of June 2017, five years have passed since the enforcement of the FIT Act in July 2012. During this period, renewables, in particular solar PV has been widely deployed and the share of renewables which was 9% in FY2011, has increased to as much as 15% in FY2016.

This report examines the outcome of the FIT scheme, pointing out how the deployment of renewables has contributed in the reduction of carbon dioxide emissions and wholesale electricity price, and how it has raised issues related to coexistence with local communities and the challenges involved in the implementation of the scheme.

Furthermore, this report makes projections of the FIT surcharge and estimates the surcharge unit price and wholesale electricity price in FY2030 on different scenarios. It shows that a wider deployment of renewables allows a decrease in wholesale electricity unit price, consequently lowering the total sum of surcharge and wholesale electricity price.
