Recently, the Global Energy Interconnection Development and Cooperation Organization (GEIDCO) held the Webseminar /Press Conference for its Fourth Anniversary. Many well-known media outlets attended and asked some high-profile questions online. GEIDCO spokesperson and experts of the Advisory (Consultant) Board and the Technical (Academic) Committee answered these questions online. So what are the questions? And the answers?
From China Environment News: At present, all countries are actively working towards the goals set by the Paris Agreement. How can GEIDCO coordinate the two tasks – tackling climate change and developing clean and efficient electric power production and transmission?
Lin Hongyu, Spokesman and Director General of Cooperation Bureau of GEIDCO: with the shortening window time for achieving the temperature control goals set by the Paris Agreement, developing clean and efficient power production and transmission will become the main way to deal with climate change. The rising greenhouse gas concentration and increasing global warming are mainly caused by fossil energy emissions. Only by curbing the use of fossil energy and implementing the decarbonization of the power system, can we effectively achieve carbon emission reduction.
By making full use of the complementarity of different countries in energy resources, seasons, time lag, and prices through power grid interconnection, GEI promotes large-scale development and large-scale economic and efficient allocation of clean energy. As a combination of clean energy, UHV and smart power grid, instead of simply referring to UHV transmission, the GEI accelerates clean and efficient power production and transmission through clean alternative, power alternative, connectivity and other relevant actions.
Meanwhile, developing a global electricity carbon market on the platform of the large power grid will highlight the market-oriented role, achieve coordinated linkage between electricity and carbon trading, energy and climate management, and accelerate global energy transition, environmental management and carbon emission reduction.
From China Meteorological News: What is the relationship between energy and climate change? Under the context of global warming, will climate affect the pattern of energy use? If the answer is yes, what are the aspects? What positive influence can GEI bring to global energy conservation and emission reduction? And the influence on climate change?
He Jiankun, Deputy Director of China's National Experts Committee on Climate Change and Senior Expert of the Technical (Academic) Committee: The key to coping with global climate change is to reduce the man-made greenhouse gas emissions, which are mainly caused by fossil energy consumption, accounting for about two-thirds of the world's greenhouse gas emissions. In order to greatly reduce the carbon dioxide emission of the energy system to zero by 2050, it is bound to promote the revolutionary change of the energy system, that is, gradually replacing coal, oil, and natural gas with new energy and renewable one to basically shake ourselves out of fossil energy. It is forced by the protection of the earth's ecological security. In other words, it is an action carried out voluntarily.
The development of GEI means to make overall use of renewable energy in different regions, which will greatly improve the utilization efficiency and economic benefits, avoid the insufficient local adjustments, such as wind and photovoltaic power curtailment, and play an important role in the security and stability of the global energy system and low-carbon.
From China Radio International: Should countries regard infrastructure investment as an important aspect to boost the economy? China's UHV investment will rise this year. Do you think other countries have the conditions to do the same?
Tomas Kåberger, Chair of Executive Board of Renewable Energy Institute and Senior Consultant of the Advisory (Consultant) Board: Now, due to the pandemic prevention and control, the global economy is slowing down. Therefore, governments thirst for projects stimulating economic growth. GEI is an attractive initiative for many countries. It may be an option for them to invest in power generation and international power infrastructure, energy and power-related technologies.
In fact, such discussions have taken place in many countries, such as the green new policy in Europe, which hopes to attract investment in renewable energy power generation and increase cross-border transmission capacity; the United States is also considering the improvement of power infrastructure to achieve large-scale renewable energy integration.
From Energy Review: In recent years, the development of big data, cloud computing, internet of things, (IoT) mobile internet, artificial intelligence, and blockchain has had a profound impact on the energy interconnection between the distribution power grid side and users. How do you evaluate the application of relevant technologies on the transmission side of the large power grid in the past 4 years and their prospects?
Michael Sterling, Fellow of the Royal Academy of Engineering and Senior Expert of the Technical (Academic) Committee: The technology represented by smart meters will be one of the next key points of GEI. At present, meters in many countries are not smart enough to achieve more control over load. We are in the right direction. We need a system to directly control the consumption side load, which is a "micromanagement" capability. If we succeed, then we will achieve the goal of building GEI faster.
From China Investment: Currently, with the far-reaching impact of the epidemic on globalization, the "inter-regional" ties on all continents may be closer, such as Northeast Asia and Africa. Does it contribute to the promotion of GEI within the region? Could you introduce the progress and prospects of the power grid interconnection in Northeast Asia?
Zhang Yibin, Spokesman and Deputy Director General of Development Bureau of GEIDCO: The epidemic is a serious worldwide challenge. Just like global problems, such as resource shortage, climate change, and environmental pollution, no country can only pay attention to its own development with no care of others because we are members of the same community of shared future for mankind.
The development of GEI is a major initiative proposed by Chinese President Xi Jinping at the United Nations General Assembly. It is not only an important solution to forging ahead the energy revolution but also an operational plan for dealing with a series of global sustainable development issues, such as climate change and environmental pollution. We can take the infrastructure development including the power grid and clean energy as a promising means to stimulate the economy during the epidemic or in the later stage.
With strong regional energy complementarity, according to the market space in Northeast Asia, there are broad prospects for energy interconnection due to the high dependence on foreign oil of major energy-consuming countries and the rich clean energy resources within the region. GEIDCO has studied and released the Northeast Asia Energy Interconnection Planning Research Report, providing the top-level design for its construction. South Korea, Mongolia, Russia and other relevant countries think highly of our achievements with active supports and have also carried out multilateral or bilateral exchanges and discussions with us. At present, the China-South Korea power interconnection project has accomplished the fastest progress and completed the pre-feasibility study stage. We are also proactively promoting energy and power cooperation, including clean energy development and power grid interconnection, with Mongolia and Kazakhstan.
