Data confirms that these state renewable mandates not only drove the explosion
of wind generation capacity development [a nearly five-fold increase from 2006 to 2011], but also established a guaranteed increasing future market for wind energy anticipated to triple in size by 2030 even if the federal PTC expires.
Wind generation capacity already is on par with coal - fired power output in Texas, due to a proliferation of wind projects at the same time coal plants are closing.
The Australian Coal Association says because of the intermittency of wind, the percentage of the installed
Australian wind generation capacity that is actually available on the average is just 25 percent to 40 percent.
But it has only helped support 4 GW
of wind generation capacity (some of which also benefited from grants), compared to the 25 GW installed under the FIT in Germany.
Canada now has 11,898 MW of installed
wind generation capacity, enough to supply six percent of Canada's electricity demand and meet the annual electricity needs of more than three million homes.
More than 90 % of
the wind generation capacity additions in 2013 were located in five states: California, Kansas, Michigan, Texas, and New York (see graph at end of article).
AEMO notes that small - scale generation investment has increased rapidly over the last three years, the Large - scale Renewable Energy Target (LRET) is driving continued investment in
wind generation capacity, and average spot market prices have been falling in every region since 2007 — 08.
Once the government decides to have
wind generation capacity, it is obliged to guarantee prices.»
