General Renewable Energy Statistics

1.Trends under the Feed-in Tariff (FiT) Regime

Newly certified renewable energy capacity soared in March 2013, reaching 23GW by the end of June 2013. The most remarkable growth was seen in the certification of non-residential PV, but wind power and biomass have also shown steady growth.

Out of such certified capacity, 1.8GW actually started operation in 9 months since July 2012 (when FiT started in Japan) till the end of FY2012 (March 2013). RE power plants, especially Non-residential PV started accelerating in April-June 2013, adding 1.9GW in 3 months and leading the total RE operating capacity to 3.7GW by the end of June 2013. It is expected to grow even more rapidly.

*1 The METI also approved 350MW biomass-coal combustion plants which started operation during this period. However, the figure is not included in these statistics since it cannot be considered as purely biomass power generation.
*2 The original METI’s number is 22,914 MW.

The following data will be updated soon.


Japan introduced a FIT regime for renewables on July 1, 2012. The ANRE has since published statistics on the renewable power plant capacity certified by the FIT regime and installed capacity. Table 1 and Figure 1 show the plant capacity certified by the FIT regime, which amounted to 13,059 MW at the end of February 2013. In particular, in February 2013 alone, 5,263 MW additional non-residential PV (more than 10kW) was certified.

Table 2 and Figure 2 show the installed capacity since July 2012 under the FIT regime. At the end of February, all the operating renewable power plants had a total capacity of 1,352 MW. Adding this figure to the 310 MW of capacity that started operation between April and June 2012 makes the total 1,662 MW for renewable power plants that started operations between April 2012 and the end of Fabruary 2013.
The published figures for December and January by the ANRE are lower than those for November 2012, because the figures published before November showed the presumed capacity based on the assumed starting date of operations stated in the FIT certification. By contrast, the figures since December only include actual capacity based on FIT purchase records. It is expected that the ANRE will release adjusted statistics for the pre-November 2012 period.

※The installed capacity at the end of March 2012 is an approximate figure, and the ANRE is examining the related data continuously in order to increase the accuracy. The published figure for the end of March 2012 by the ANRE/METI Renewable Power Plant Certificate is approximately 20,000MW. The difference between Table 3 and the ANRE figure is due to the way that effective digits are considered.
※The published figures for December and January by the ANRE are lower than those for November 2012, because the figures published before November showed the presumed capacity based on the assumed starting date of operations stated in the FIT certification. By contrast, the figures for December and January only include actual capacity based on FIT purchase records. It is expected that the ANRE will release adjusted statistics for the pre-November 2012 period.

2.Renewable Energy Statistics from Energy-related Organizations

Various energy-related organizations publish renewable energy statistics. The International Energy Agency Photovoltaic Power System (IEA PVPS) Program, one of the Implementing Agreements of the IEA, surveys and publishes statistics on the cumulative installed capacity of photovoltaics in various countries. It published preliminary statistics in April 2013 on cumulative photovoltaic installations at the end of 2012, stating that Japan had approximately 7,000 MW of cumulative installed photovoltaic capacity (Figure 4).

The Japanese Wind Power Association (JWPA) publishes figures on installed wind capacity in Japan (Figure 5). Despite the start of the FIT in July 2012, wind energy installation in 2012 in Japan was weak due to the abolishment of subsidies for wind energy in 2010 and issues related to difficult grid connections.

3.Electric Power Survey Statistics

The Agency for Natural Resources and Energy (ANRE) in the Ministry of Economy, Trade and Industry (METI) publishes monthly power generation statistics for various energy sources. The statistics on the sources of renewable energy have been published since April 2012. According to the electric power generation statistics, the power generated from hydro, wind, photovoltaic, geothermal, and biomass sources by General Electricity Utilities, Wholesale Electricity Utilities, Specified Electricity Utilities, Power Producers and Suppliers, and Non-utility Generation (maximum power generation capacity over 1000 kW) in 2012 ranged from 10,953 GWh (April 2012) to 7,817 GWh (September 2012) (Table 4, Figure 6). The total amount of power generation changes based on variations in hydropower, which includes large-scale power plants. Figure 7 excludes the hydropower values compared with Figure 6. This figure shows that the amount of power generated by photovoltaics is small compared with biomass, wind, and geothermal sources.
