The power-generating capacity of Japan’s renewable energy systems surpassed earlier government forecasts, The Nikkei reports.

Japan is attempting to phase out nuclear power by replacing it with renewable sources to generate electricity, particularly solar power. The Ministry of Economy, Trade and Industry announced Wednesday that alternative-energy equipment is capable of producing a total of 1.3 million kilowatts at the end of August, more than half of the 2.5 million kilowatts estimated to be in place at the end of the fiscal year.

680,000 kw was brought online in the first five months of this fiscal year. Solar equipment for homes accounted for 600,000 kw while nonresidential solar capacity stood at 60,000 kw. Wind and biomass contributed 12,000 kw each. Solar power-generated electricity is expected to expand further as solar projects gain momentum across Japan.
