The Forecast of Energy Demand and the

China is rich in wind energy resource, according
to the data collected from more than 900
meteorological stations, it is estimated that
nationwide total wind potential on land at 10m
height would be 3.2TW, among them 253GW
considered technical available to be utilized, in
addition, 750GW were estimated for offshore, thus
1TW in total. Consider the modern wind turbine
hub height is more than 50m, the above estimation
maybe doubled. The areas with abundant wind
energy resource mainly in northern China,
southeast coastal line and vicinity islands.

3. Wind Planning Policy

• Current Incentive Policies
• Approval procedure 50MW by provincial NDRC
• VAT 17 to 8.5
• Income tax 33 to 15
• Loan payback period from 7 years to 15 years

19
Outline of Wind Power Project

• Detailed wind power resource out their
  distribution in China, onshore and offshore
• Present situation of wind power in China
• Utilization (off gird and grid connected)
• Manufacture capability
• Market share of domestic and foreign companies

20
Outline of Wind Power Project

• Future of wind power in China
• Roadmap of development
• Market forecast
• Barriers of development
• New technology trends
• Key problems and issues of development

21
Outline of Wind Power Project

• Legistration and policy requirements
• Tax
• Renewable Portfolio Standard
• Concession Approach of wind power
• Preferential policies for wind power in Denmark,
  Germany, India, USA, UK and other countries
• Relationship between wind power and electricity
  sector reform

22
Outline of Wind Power Project

• Concession Approach of wind approach
• Content of Concession Approach
• Opportunity of foreign companies
• Cooperation modes
• Case study of wind power concession
• For already approved project
• For projects in planning stage

23
Biomass

• Straw and stock resources are about 700 mil.
  tons, equivalent to 300 mil. tce
• Feature highly scattered, very difficult for
  collection the radius of economically feasible
  collection area is less than 5 km
• Several ways of utilization
• Gasification ? for cooking and power generation,
  problems tar blockage, high CO content
• Gasification ? methanol, DME, small scale,
  relative low efficiency, economically is not
  feasible
• Rapid pyrolysis raw fuel liquid, scale,
  shortage of skilled operators

24
Biomass (contd)

• For making solid particles
• Large consumption of energy for forming
• New method of forming, about 30 kWh per ton
  (heating value about 60 of ce)
• Onsite production and onsite utilization as
  alternative to coal (especially designed portable
  machine and stoves)
• Biofuel
• Great development of biofuel industry over the
  last ten plus years, production capacity of EU
  more than 1 mil. tons in 2001
• Recently, RD on biofuel has been undertaken in
  many domestic universities and institutes. In
  2001, a production base of 10,000 tons annual
  yield was built in Wuan city, Hebei Province

25
Biomass (contd)

• Advantages of biofuel
• Ease the pressure of oil import
• In the near term, use depleted edible oil and
  oil-containing biomass as feedstock
• In the medium term, use farm and forest crops in
  scaled plantation
• Lower the emission of vehicle exhaust, also
  particles and smoke intensity
• Synergetic utilization of resources
• Favor the adjustment of agriculture structure,
  increase the income of peasants

26
Solar energy

• Evolution of Photovoltaic (PV) Cell
• First generation PV cell Silicon Crystal PV,
  about 90 of international market, very costly
  domestic 3035 RMB/Wp
• Second generation PV cell Thin Film PV (TFPV),
  in the transition stage from RD to scaled
  production.
• The most promising are cadmium telluride TFPV and
  Cadmium-Indium-Selenium TFPV, which are also the
  key topic of national 863 project
• In 2003, cadmium telluride multi-crystal TFPV,
  developed by Sichuan University, achieved the
  conversion efficiency of 13.38. Dye-sensitized
  TiO2 TFPV reached 7 efficiency.
