According to data released by the Japanese Ministry of Economy, Trade and Industry (METI), Japan installed 18,757 MW of renewable capacities since the start of its feed-in tariff programme in July 2012 (until March 2015). The bulk of the new capacities consisted in solar parks (18,108 MW). Renewable capacities additions have accelerated, from 1,758 MW between July 2012 and March 2013 (mainly residential solar projects with 969 MW and commercial solar projects with 704 MW), to 7,139 MW in 2013-2014 (including 5,735 MW of commercial solar projects and 1,307 MW of residential projects) and 9,860 MW in 2014-2015 (including 8,572 MW of commercial solar projects, 821 MW of residential solar projects, 221 MW of wind power and 158 MW of small-hydropower projects). In the 2014-2015 fiscal year, renewables accounted for 3.2% of power generation (not including hydropower, 9%).
Over this July 2012-March 2015 period, the ministry approved a total of 87,680 MW of renewable projects, mainly commercial solar projects (78,840 MW) and residential solar projects to a lesser extent (3,790 MW). In addition, 2,290 MW of wind projects, 2,030 MW of biomass and 660 MW of small hydropower projects have been approved.
