The installed capacity of wind power generation in FY 2009 was published on June 25, 2010. JWPA report the installed capacity of wind power generation at the end of December 2011 (surveyed by JWPA).
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 Standards Act; however, installations have been recovering steadily since that time. Nevertheless, the national goal of 3 MW as the installed capacity for fiscal year 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, approximately only 25 MW of ongoing projects will be granted a subsidy, and the estimated installed capacity for wind power generation will be approximately 2.7 MW in FY 2013. The early decisions for FIT and the mid- to long-term installation goal are matters that must be determined.
The installed capacities by fiscal year:
FY Cumulated capacity Increased capacity in the year
MW Number of units MW Number of units
2005 1,085 1,059 159 139
2006 1,490 1,316 405 257
2007 1,675 1,413 184 97
2008 1,883 1,533 208 120
2009 2,186 1,681 304 148
2010 2,442 1,807 256 126
The installed capacity in FY 2010 will be announced by the New Energy and Technology Development Organization (NEDO) by the end of July. The information from NEDO may differ slightly from the data surveyed by JWPA due to the differences in the recognition of months when newly installed generators started and the months listed as the ending date for removed generators.
