The installed capacity of wind power generation in FY 2010 was published on June 17, 2011. JWPA inform you of the installed capacity of wind power generation at the end of December 2011(surveyed by JWPA) and the estimated data for FY 2011(at the end of March, 2012).
Cumulative installed capacity of wind power generation at the end of December, 2011 = 2.501 MW, 1,832 units on 417 wind farms
Installed capacity of wind power generation in 2011 = 166 MW, 78 units on six wind farms: Approximately 60% of the previous years
In 2007, the installed capacity of wind power generation decreased to the level of less than one-half of 2006 due to the influence of the revised Building Standard Law; however, installations have been recovering steadily from that time. Nevertheless, the national goal of 3 MW as the installed capacity for FY 2010 was not, unfortunately, achieved due to the termination of the subsidization program for newly constructed wind farms in consideration of the transition to feed- in- tariff (FIT).
On the other hand, only a few ongoing projects will be granted subsidies, and the estimated cumulative installed capacity for wind power generation will be approximately 2.6 MW in FY 2013. The detailed terms and conditions of s FIT and the mid- to long-term installation goal are matters that must be determined immediately.
The installed capacities by fiscal year, including the estimated data for FY 2011, are listed below:
FY Cumulative installed capacity Increased installed capacity in the year
MW Number of units MW Number of units
2006 1,490 1,316 405 257
2007 1,674 1,413 184 97
2008 1,880 1,533 206 118
2009 2,184 1,681 304 148
2010 2,440 1,807 256 128
2011 2,522 1,840 82 33*
* Approximately 30% of the previous years
The installed capacity in FY 2011 will be announced by New Energy and Technology Development Organization (NEDO) by the end of June. The information from NEDO may differ slightly from the data surveyed by JWPA due to the differences in the recognition of months, e.g., when newly installed wind power generators started operation, and when outdated wind power generators were dismantled.
