Japanese Renewable Energy Installation Records

The Japanese government has issued a report on installations in the running fiscal year (from April 2012 to 2013) until end of November. Thanks for this tweet by Hiro Matsubara for the link.

The Japanese numbers are somewhat difficult to understand. They report two sets of numbers for each technology. One is the new capacity that has already started operations. The other, in most cases larger one includes also projects that have already been admitted under Article 6 of the feed-in tariff law by the Japanese government, but have not yet started electricity generation.

In order of importance, here are the figures.

Megasolar has 0.371 GW in started and 2.535 GW in admitted capacity.

Rooftop solar has 1.027 GW in started and 0.727 GW in admitted capacity.

Wind has 0.01 GW in started and 0.343 GW in admitted capacity.

Right now, everything else is still just about zero.

Capacity from all sources adds up to 1.443 in started and 3.648 in admitted capacity.

In the regional mix, the most northern part of Japan (Hokkaido) leads by a large margin in the amount of megasolar capacity admitted, with 437,6 MW, beating second place southern Japan Kagoshima prefecture at 177.5 MW by a factor of over two.

Obviously, in Japan it makes more sense to build solar where the land is cheap than where the sun shines. On the other hand, Hokkaido is at 43 degrees north, which is south of Bavaria (48 degrees north), the southern German state where much of Germany’s solar capacity is found.
