On September 23,the Association of Electricity Supply Industry of East Asia and the Western Pacific (AESIEAP) 2019 CEO Conference is held in Cebu, Philippines. With the theme of “Energizing Countries, Empowered Communities”, the conference invited more than 200 ministers and industry leaders from the Asia-Pacific region to discuss regional energy challenges and to develop innovative solutions to further transition and sustainable development of the power industry in the region.
At the conference, Global Energy Interconnection Development and Cooperation Organization (GEIDCO), makes debut release of Asia Energy Interconnection Research Report, proposing the overall plan and key projects for Asia energy interconnection projects. The report offers wisdom and solution for ensuring power supply, accelerating clean transition, and promoting energy infrastructure and the development of upstream and downstream industries in Asia. Liu Zhenya, Chairman of GEIDCO and CEC (China Electricity Council) attended the conference and delivered a keynote speech entitled "Power Transition in China and Innovative Development of Global Energy Interconnection".
Asia Energy Interconnection Research Report was officially launched
GEI is a modern energy system steering towards clean energy production, widespread energy allocation and electricity-centered energy consumption as well as an important platform for large-scale development, transmission and utilization of clean energy resources at a global level. In essence, the concept of GEI is “Smart Grid +UHV Grid+ Clean Energy”.
Asia Energy Interconnection is an important part of GEI. GEIDCO releases the Asia Energy Interconnection Research Report at the 2019 AESIEAP CEO Conference.
Based on current status of energy and power sector, development characteristics and energy resource endowments of different countries in Asia, the report systematically analyzes the power supply and demand trends and power flows in Asia, and formulate the overall scheme of grid interconnection for whole Asia as well as 5 major regions, including Southeast Asia, East Asia, South Asia, East Asia and West Asia. The report proposes the overall planning and 27 key cross-regional grid interconnection projects for Asia Energy Interconnection, and also look into prospects for future intre-continental interconnection among Asia, Europe and Africa. Aimed at promoting green and low-carbon development, higher efficiency, multi-energy complementation, and regional cooperation, Asia Energy Interconnection will further facilitate coordinated development of economy and society, resource and environment, and man and nature within the region.
Liu Zhenya noted that, the energy and power sector in Asia enjoys rapid development, but faces three aspects of challenges in the long run, namely rapid growth in energy demand, great pressure in carbon mitigation, and ensuring power supply. At present, Asia’s primary energy consumption accounts for 46% of the world total. Asia’s fossil energy accounts for 83% in primary energy consumption, with an annual carbon dioxide emissions of 17 billion tons, accounting for nearly half of global carbon emissions from energy consumption. Asia’s per capita annual electricity consumption is only one-third of that in OECD countries, and still 240 million people don’t have access to electricity.
In Asia, hydro, solar and wind energy resources are abundant. Their reserves take up 46%, 25% and 21% of the world total, respectively. Asia Energy Interconnection (AEI) gives play to Asia’s clean energy advantages, and is the necessary path to realize sustainable development. According to Liu Zhenya, the main target is to accelerate solar and wind power development in West Asia, Central Asia, southern South Asia, northern and western China and Mongolia, as well as hydropower in Western China and Southeast Asia; then transmit these clean energy to South Asia and East Asia. In Asia, future power flow will be from West to East and from North to South, with mutual support among various energy sources, forming a new pattern of energy development.
Based on GEIDCO’s estimates, by 2050, the total investment of AEI is 18.7 trillion US dollars, including 14.3 trillion US dollars in power source, and 4.4 trillion US dollars in power grids, creating 150 million jobs.
The energy network, information network and transportation network are like our “vascular system”, “neural system” and “arm-leg system”. Liu Zhenya remarked that, compared with the information and transportation networks, energy interconnection is obviously lagging behind. As the UHV technologies achieve breakthroughs, the global vascular system will undoubtedly be established, and drive the world into a new era of “Watts, Bits and Meters” integration, or Energy, Information and Transportation Integration(EITI).
Remarkable progress in China’s energy transition
China is the only country with an ultra-large power network that has not experienced any major black-outs in the world, which ensures strong support to China’s economic and social development, remarked Liu Zhenya. Since the new century, China’s economy has been developing rapidly, substantially increasing the energy demand. However, it also brings about resource shortages, environmental pollution and other noticeable problems. To address these challenges, relying on technological innovation, China has accelerated energy transition, and promoted clean development in energy and power sector. With years of hard work, China’s electric power industry, in terms of its scale, structure, safety and efficiency, has advanced to a new level.
According to statistics, by the end of 2018, the installed capacity of power generation in China reached 1.9 terra watt, of which hydro, wind and solar power accounted for 350 giga watts, 180 giga watts, and 170 giga watts respectively, all ranking the first in the world. The length of transmission lines at 35 kilovolts and above reach 1.96 million kilometers, with total power transformation capacity of 6.2 terra watt volt-amperes. China has realized power supply to every household. The whole society consumed 6,800 terra watts of electricity, and the per capita annual electricity consumption was 4,900 kilowatt hours. Such achievements strongly support the economic and social development.
Clean development is making remarkable progress. In 2018, China’s clean energy installation, in terms of its proportion in power generation, rose from 25% in 2010 to 40%. Nearly half of the newly added electricity demand is supplied by clean energy. Annually, it replaces 800 million tons of coal, reduces carbon dioxide emissions at 1.5 billion tons, and sulfur dioxide and other pollutant at 7.5 million tons.
In terms of UHV transmission, there are “10 AC and 14 DC” UHV grids in operation, altogether 24 UHV projects. There are “4 AC and 4 DC” UHV grids under construction, altogether 8 UHV projects. China has established the world’s largest UHV AC and DC hybrid grid network. China’s UHV technology has been successfully applied in Brazil with Belo Monte double-circuit ±800-kilovolt UHV DC lines. It has become a core energy corridor for transmitting rich hydropower from Amazon River.
In terms of smart grid, China has rolled out applications of smart grid, put into operation a number of world-leading innovative projects, including solar, wind power, energy storage and transmission demonstration project in Zhangbei. China has built the world's largest electric vehicle charging network, with the number of charging piles exceeding 1 million. Altogether, more than 500 million smart meters are installed, to enable comprehensive service platform for smart power use.
GEIDCO is committed to promoting the world’s sustainable development, and actively builds an international cooperation platform for mutual consultation, co-development, sharing and win-win results. Currently, there are more than 700 members from over 100 countries and regions. GEIDCO has released the GEI Backbone Grids, development index, technical equipment, standard system and related regional energy interconnection research reports. Within this year, it will complete the reports and studies for the global and every continent.
