4 National Renewable Energy Power Generation Plan Target Year Wind Power Installed Capacity (GW) Power Generation (TWh) 10 30(50) (xx) 400(xx) Biomass Power Installed Capacity (GW) Power Generation (TWh) Solar Power Installed Capacity (GW) Power Generation (TWh) (20) (XX) 100(XX)

5 Wind Power Installed Capacity At the end of 2008, wind power installed capcity in China had reached 10GW, which was the goal of % % % %

6 Solar Power Installed Capacity The National Energy Administration has decided to expand China's solar power installed capacity to 2 GW by 2011, with a subsidized price for solar power of 1.09 yuan per kwh in some areas.

7 Some Policies to Support Renewable Energy Development Regulation and Management Measure of RE power (by NDRC) Regulation on Renewable Power Pricing and Cost Sharing (by NDRC) Guided Catalog of RE industry development(by NDRC) Some national standards (Standard for solar building, Geothermal heat pump by Ministry of Construction, Standard for Solar PV power and wind turbines etc by Standardization Administration of China.) Fund earmarked for RE (by Ministry of Finance)

8 Wind Power Price Policy (July, 2009 by NDRC) Resource Area Grade Standard wind power price (Yuan/kWh) Area Grade I 0.51 Inner Mongolia Autonomous Region except Chifeng, Tongliao, Xingan, Hulunbeier;Urumqi, Ili, Changji, Karamay, Shihezi of Xinjiang Uygur Autonomous Region Grade II 0.54 Grade III 0.58 Zhangjiakou, Chengde of Hebei Province;Chifeng, Tongliao, Xingan, Hulunbeier of Inner Mongolia Autonomous Region; Zhangye, Jiayuguan, Jiuquan of Gansu Province Baicheng, Songyuan of Jilin Province;Jixi, Shuangyashan, Qitaihe, Suihua, Yichun, Daxinganling of Heilongjiang Province;Gansu Province except Zhangye, Jiayuguan, Jiuquan; Xinjiang Uygur Autonomous Region except Urumqi, Ili, Changji, Karamay, Shihezi;Ningxia Hui Autonomous Region

9 Solar Power Stimulus Policy Solar Energy Roof Plan (March, 2009) (1)Emphases on building integrated photovoltaic demo projects (2)Subsidies 20 Yuan/W of the BIPV system. Golden Sun Pilot Program (July, 2009) (1)Subsidies more than 500 MWp in the next three years. (2)Offer percent of investments for solar power projects. Some Policy by local Government

10 Biomass Power Policy Price for biomass power: feed-in-tariff In the first 15 years, adopt the subsidy Price: Coal fired plant :0.25Yuan/kWh, biomass power : Yuan/kWh Others Provide a long-term policy and ensure the fixed price etc.

28 Solar Decathlon Europe 2010, Tianjin University Participation The Solar Decathlon Europe 2010 came about from a commitment by the Government of Spain together with the Government of the United States to organize the competition in Europe for universities to design and build a self-sufficient house using solar power as the only source of energy. We are aiming at achieving the maximum level of sustainability in a Solar-powered, energy selfsufficient, user- and environmental- friendly house.
