13 2. Potential Analysis Mongolia The power demand forecast report of Mongolia put forward 3 scenario. The growth rate of power electricity demand in Mongolia will be very fast. Power electricity consumption Power load forecast forecast Unit: TWh Unit: GW %,6%,6% 6.2%,6.2%,2.9% %,15%,19% %,14%,17% Low Mid High Low Mid High Mongolia s power system is not particularly large. Although the power consumption will increase very rapidly,the amount of power consumption is relatively small and the 12 demand for domestic installed capacity will not be very large.

14 2. Potential Analysis Mongolia Mongolia has abundant energy resources, which can be converted into power electricity. According to preliminary estimates, Mongolia export power potential is more than 15GW in the eastern and southern regions. In the future, Mongolia would actively seek power consumption market in the Northeast Asian countries. Power development 蒙古国 potential>15gw 中 国 13

15 2. Potential Analysis Republic of Korea The 7 th power demand and supply long-term planning ( ) made forecast for power demand of ROK. The power electricity consumption may reach to 657TWh in South Korea may need to add new power capacity of 28GW from now to This demand may be met by importing energy resources to build power plants, or by importing power electricity directly from neighboring countries. Power electricity consumption forecast Unit: TWh %

16 2. Potential Analysis Republic of Korea The power generation in ROK are mainly coal-fired and gasfired units, while the amount of coal and gas resource in ROK is relatively small which largely rely on import. Korean power companies hope to guarantee their domestic power supply through power interconnection with neighbors

17 2. Potential Analysis Democratic People's Republic of Korea Recently, the situation on the Korean Peninsula has gradually eased. The future power construction market in North Korea is worthy of attention and research. At the same time, it also provides more possibilities for the Northeast Asia power interconnection channels. 16

18 2. Potential Analysis Japan The forecast by EIA on power installed capacity and generation of Japan are as follow. The demand of power generation in Japan is not growing very fast in the future. However, because of the large base amount, the new installed capacity is still relatively large, need to add more than 40GW new power generation. Power electricity production Power generation capacity forecast forecast Unit: TWh Unit: TkW 0.7% % % % % %

19 2. Potential Analysis Japan power plants distribution map Thermal Hydro Nuclear The power generation in Japan are mainly coal-fired, gas-fired, oil-fired and nuclear power units, while the amount of coal, gas and oil in Japan is relatively small which largely rely on import. Moreover, Japan focuses on new energy development and utilization to ensure environment protection and sustainable development. Japanese companies has been 18 conducting power interconnection in NEA related research positively.

21 2. Potential Analysis China By the end of 2017, the overall capacity in China is 1780GW. The average annual growth rate from is 7.3%. Hydro power is 340GW, wind power is 160GW, solar power is 130GW. Renewable energy power generation accounted for 38% Unit:GW 13.3% 12.5% % 9.9% % % 8.8% 7.9% 7.8% Installed Capacity Increase Rate 14% 12% 10% 8% 6% 4% 2% 0% Thermal 62% 2017 Power Generation Structure Hydro 19% Nuclear 2% Wind 9% Solar and Other 8% 20

22 2. Potential Analysis China According to the 13 th Five-Year power development planning, the total power consumption of China will reach 9500 TWh in In the next decade. Power demand in Northeast and North China will continue to grow steadily. Power electricity consumption forecast Unit: TWh % 3.7% % % % North-East Region 3.4% Unit: TWh 4.7% China North Region 21

23 2. Potential Analysis China Before 2025, northeast and north China power generations are oversupplied, which have the potential to export clean energy to the neighboring countries , north-east and north China have certain space for power growth, which could consider to receive power from outside. In the long term, China encourages to conduct research on financial and technical feasibility of more power interconnection projects, based on the principle of mutual benefits. 22

25 3 Outlook on power interconnection in North-East Asia 24

26 3. Outlook Challenges Political factors: cross-border power connectivity requires relevant countries have strong political trust; needs to coordinate the demands of all stakeholders; concerns on degrading of state energy security. Economic and business factors: Large investments; Complicated business model. The payback period is long and uncertain, especially under different legal and national systems. Technical and standards factors: requires to coordinate the planning and operation of power systems in different countries, including grid code, electricity market design and dispatching, etc.. 25

27 3. Outlook NEED TO STEP BY STEP Road-Map Idea: Short term(now-2025): Give priority to the implementation of less difficult interconnection projects. Actively conduct research on difficult projects. Improve consensus. Long term( ): Based on the experience of implemented interconnection projects, we will expand the consensus among NEA countries and promote wider regional power interconnection. 26

28 3. Outlook China-Russia Short-term: North-east and north China are all over-supplied. Therefore, China and Russia could maintain a stable power trade in recent. Carrying out research work to expand the scale of interconnection. Long-term: North China has certain space for power growth. It is possible to promote large-scale power interconnection projects in China and Russia. Research could be conducted on the scale, plan, economics of power transmission project between China and Russia. 27

29 3. Outlook China-Mongolia Short-term: Strengthen the interconnection between Mongolia southern region and China Inner Mongolia by 220kV or 500kV. Expand the scale of power trade between the two sides. Improve the stability of regional power grids, and promote the optimal allocation of resources in close border area. Long-term: It is possible to construct a large-scale power interconnection channel, which exports the power from southeast Mongolia to north China. The cross border power trade can be carried out in the early stage. The large-scale power interconnection could be taken into consideration according the power market, electricity tariff and etc.. 28

30 3. Outlook China-Korea-Japan Power Interconnection Long-term: Technology Undersea power transmission is Difficult Economics Huge investment Power source Renewable energy from China, Russia and Mongolia Distribution Complex There are still technical, economic and other related issues in the power interconnection between China, Korea and Japan that need further in-depth research. In the future, relevant projects can be promoted in a timely manner according to relevant research results and the willing of all countries

31 3. Outlook Russia-China-DPRK-Korea-Japan Power Interconnection Long-term: For long-term, research could be conducted to explore the feasibility of the interconnection on Russia-China-DPRK-Korea-Japan, including the transmission scale, technology selection, economic evaluation, operation mode, business model, etc.. 30

32 3. Outlook Suggestions 1. Strengthen the cooperation mechanism for power interconnection Strengthen policy communication between countries, make full use of existed multilateral cooperation platform or mechanism, promote the cooperation mechanism of power interconnection. Mobilize the enthusiasm of relevant enterprises and financial. 2. Jointly carry out the research and planning work on power interconnection Carry out the research jointly on power interconnection planning and make reasonable roadmap with widely participation.

33 3. Outlook Suggestions 3. Promote the exchange of grid construction and operation standards Study on the grid construction and operation standards of multiple countries. Strengthen the exchange of related standards, to provide support for power interconnection projects. 4. Explore the construction of regional power market Study power market mechanism of related countries, and formulate regional power trading and dispatching mechanism. Explore to establish regional power market. 32

34 3. Outlook Suggestions 5. Increase financial support Build a platform for cooperation between financial institutions and power enterprises, broaden financing channels, reduce financing costs, and provide financial support for power interconnection projects. 6. Promote innovation and application in some key technologies Accelerate technological innovation, solve the problems of long-distance transmission of large capacity under ocean.
