We achieve rapid development of wind power from 2 gigawatts to 50 gigawatts in five and a half years. New energy scale from small to large, standard from scratch, technology from follower to lead to run, control ability from weak to strong, the development of new energy in China has reached a new level. After several years of practice and exploration, we have a deeper understanding on the development of wind power and other new energy. 8
First, the development and utilization of new energy are highly relevant to resource endowments. China's wind energy resources are mainly concentrated in the "Three North" region, accounting for more than 90% of the country; solar energy resources are concentrated in the western and northern regions, accounting for more than 80% of the country. Currently, more than 90% of the installed new energy capacity is concentrated in the region of the "Three North". China's wind energy resource maps China's solar resource maps 9
"Three North" region load is small, the capacity of the new energy market is limited. Mengxi, Eastern Inner Mongolia, Gansu, northern Hebei four regional wind power installed capacity accounted for 50% of the country, but only 10% of the country's electricity consumption. Reverse distribution of new energy resources and load determines that China's new energy should large-scale centralized explored and long-distance delivery. delivery Wind d power generation ratio for the country Electricity used accounts for the country China's electric power load distribution diagram 新疆 西藏 青海 黑龙江 吉林 内蒙古 辽宁 京河北津 宁夏 山西 山东 甘肃 陕西 河南 江苏 安徽上海湖北四川浙江重庆 贵州 湖南江西福建 云南 广西 广东 台湾 澳门香港 海南 60% 50% 40% 30% 20% 18.1% 12.0% 10% 0% 风电发电量占全国比例用电量占全国比例 9.7% 3.3% 33% 0.7% 20% 2.0% 11.6% 3.4% 51.3% 9.3% 蒙西蒙东甘肃冀北 Total 合计 Mengxi Mondon Gansu Jibei 10
Second, the level of new energy consumption is closely related to the power structure. The power structure in China and abroad are different, the system peaking more difficult, the new energy consumptive problem more difficult. "Three North" power structure t is single, mainly coal-fired power and heating unit, the flexible sources such as gas-electric and pumped storage power station is less than 2%. The winter peak is particularly difficult. 100% 1.2% 0.7% 0.5% 0.8% 80% 60% 40% 20% 77.4% 90.6% 65.3% 81.3% The Coal-fired heating unit proportion accounted for the of coal-fired proportion of thermal power power units Jilin 68.8% 74.4% 0% North 东北 East North 华北 China North 西北 West Three 三北 North 合计 Flexible source Wind Others Hydro Coal-fired 灵活电源 ( 抽蓄 燃油燃气 ) 风电其他常规水电煤电 "Three North" regional power structure Mengxi 78% 57% Gansu 56% 31% 11
The third is to promote the development of new energy need to improve the policy support system. Auxiliary services market:denmark through the joint operation of wind power plants and heat units, auxiliary service compensation mechanism, joint optimization of wind power and conventional power run. The demand side response:denmark through real-time pricing response and adjust the electricity load, to promote low load time new energy power consumptive. By encouraging electric vehicles in Valley segment storage, configuration thermal storage device and heat pumps p toimprove the level of new energy consumptive. Feed-in tariff policy:germany to establish a flexible tariff adjustment mechanism, achieved photovoltaic power generation balanced and orderly development. Last year new scale beyond the annual plan, then increase in the proportion of feed-in tariff cut down otherwise appropriate reduction in the proportion. 12
The Chinese government promulgated the "Renewable Energy Law", developed feed-in tariff, cost-sharing, priority network connecting policy to encourage the development of new energy, and these policies played an important role in promoting the rapid development of new energy. With the new energy large-scale development, we need to further improve the existing policies.

In July 2012, the National Energy Administration issued a "the 12th Five-Year Plan of renewable energy development, "the 12th Five-Year Plan of wind power development and the 12th Five-Year Plan of solar power development. Planning objectives Wind power: 100 gigawatts in 2015, 200 gigawatts in 2020. Solar power: 21 gigawatts in 2015, 50 gigawatts in 2020. 28
Wind power planning and layout Focus on construction of nine large-scale wind power base in Hebei, Mondon, West Inner Mongolia, Jilin, Gansu, Shandong, Jiangsu, Xinjiang 600 and Heilongjiang, including seven in the "North" region, accounting for 65% of the size of the country's total planning. 哈密 1000 酒泉 1100 蒙西 1300 河北 1100 蒙东 800 山东 800 黑龙江 600 吉林 600 江苏 600 Nine large-scale wind power base (Unit: 10 MW) 29
Solar power generation planning layout The construction of large-scale solar power plants in the western and northern regions, the development of distributed photovoltaic power generation in the eastern part. The large-scale solar power plants account for about 50 percent of the total size of the national planning. Construction of solar power layout (Unit: 10 MW) Power generation category Planned installed capacity in 2015 Planned installed capacity in 2020 1 Solar power station 1100 2300 Photovoltaic power plants 1000 2000 Solar thermal power station 100 300 2 Distributed PV power generation system 1000 2700 Total 2100 5000 30
Nationally, the total installed capacity of wind power is only 5% of total power installation. The fundamental measure to solve the"threenorth"regionwind power consumption is to speed up the construction of trans-regional transmission channel, extending the "Three North" wind power nationwide to dissolve. We also have the plan to transmit Mongolia and Russia wind, solar and coal energy to China s load center. Wind power electricity flows and consumptive market 31
Speed up the construction o f pumped storage power station and other peaking power sources, improve system flexibility, and improve the level of new energy consumptive. SGCC is planning to build pumped storage power station in 2015 to reach 16 million kilowatts, more than 36 million kilowatts in 2020. Pumped Storage Power Station site resources 32
Next work plan of SGCC: 1 Attaches great importance to the wind power consumption, accelerate the construction of the transmission channel, mining peaking potential. 2 Carry out wind power and other new energy base transmission planning optimal adjustment. 3 Strengthenth wind power and network management, well done distributed power grid work. 4 Work to improve the technical standards for new energy. 5 Strengthen the analysis and research of major issues. 33
Accelerate the development of new energy is the major way for China to promote the adjustment of energy structure, to achieve a low-carbon development. The development of new energy needs trans-regional, regional industry-wide collaboration and support. I believe that with the joint efforts, China's new energy must be rapid and healthy development. 34
