Theoretical exploitable amount of the wind power in China could amount to
322,600,000 KW. If the exploitable amount takes up just 1/10 of the total, while the
real area swept by the bade is 785 times than the area of the airflow square (total
area of a blade with a diameter of 1 m amounts to 0.758 m

), the exploitable amount
of wind power in China is: R

As suggested in Table
5.6
, places with abundant wind power are situated in the
north-west, north-east, north China as well as the east and south-east coastal areas.
Total capacity of Grid-connected wind power is 5,912,000 KW, which only
takes 2.3 % of the total 253,000,000 KW of exploitable wind power reserves.
The wind power at sea is three times larger than in land. Great potential for wind
power generation in the country can be safely assumed.
During 2005-2009, installed capacity of wind power had increased by at least
100 % each year. In 2010, total installed capacity stood at 31,000,000 KW; the
amount of 2009 had surpassed 13,000,000 KW.
For every three newly installed wind power turbines in the world, one-third of
them were built in the country in 2010. The entire installed capacity has increased to
30,000,000 KW to achieve the planned goals of 2020, 10 years ahead of schedule
(Fig.
5.6
).
China has recently constructed the seventh “hundred-million-KW level” wind
power generation base and launched special bids for the first group of wind farms at
sea near coastal areas.
In 2010, the 100,000 KW wind power farm at sea of Shanghai Donghai Bridge
was founded and put in to operation. The installed capacity has already reached
102 MW.
