In-Depth Information
Manufacturing wind power equipments should conform to national regulations.
China has included important projects of domestic production on large-scale wind
power equipments in national plans of high-tech development.
In regards to national debt and specially permitted projects, there are regulations
about the ratio of imported equipments, which must be higher than 70 %.
The regulations reduce Chinese wind power costs.
5.1.6.3 Investing in Wind Power
Domestic wind turbine generator systems rely on imports, which comprise the
main part of total investment for wind power station construction that accounts
for 70 % [

].
The expansion of the localization rate of turbine generator production has
reduced investment costs for wind power.
Although the capacity of each wind turbine is increasing, the localization rate of
large capacity wind power farms remains low due to inadequate investment in
domestic technological research.
The unit investment cost of wind power in the country is about 8,000-10,000
yuan per kilowatt, while the unit cost of thermal power is 5,000 yuan per kilowatt
[

].
High investment costs have hindered national wind power development. How-
ever, investment costs per kilowatt of WTGS is decreasing sharply with the
augmentation of greater wind power capacity.
Guidance should be provided for the commercialized of wind power by deter-
mining the lower costs.
In 2010, the total installed capacity of domestic wind power has reached
30,000 MW.
Large-scale exploitation of sea wind power has officially begun. During the “Twelfth
Five-year” plan, the newly- increased installed capacity of the domestic wind power
sector continues to grow at an annual speed of more than 10,000 MW each year [
23
].
Fields for wind station construction, grid connected generation, wind power
equipment and manufacturing might become hot spots for investments.

Biomass Energy
Main applications of biomass energy in China are biomass power generation,
biomass gasification (including methane), biomass briquettes and liquid bio-fuel.
Biomass power generation includes biomass power generation of agriculture and
forestry, garbage power, methane gas, etc.
