Shu Yinbiao explained in detail the "re-electrification" strategy of State Grid

Polaris Thermal Power Network News: "The development of clean energy must continue unswervingly in order to achieve my country’s goal of developing renewable energy and fulfill the commitments of the State Grid. At the moment, we must make great efforts to solve the problems in the development of clean energy. Wind, abandonment of light, and abandonment of water." Shu Yinbiao, a member of the National Committee of the Chinese People's Political Consultative Conference and chairman of the State Grid, said in panel discussions and public speeches several times that he would fight against the "three abandonment" of clean energy through "re-electrification".

In 2005, the State Grid di entered 46th in the "Fortune 500", and now it ranks second in the world. The State Grid, under the helm of Shu Yinbiao, is trying to promote the development of clean energy in China and the world, and set a benchmark for energy transformation. . Data as of the end of last year showed that the installed capacity of clean energy from the State Grid exceeded 490 million kilowatts, making it a large-scale grid of clean energy in the world.

Recently, Shu Yinbiao accepted an exclusive interview with a reporter from the Securities Times after the CPPCC panel discussion. Focusing on the "re-electrification" strategy, Shu Yinbiao explained in detail the development of clean energy and the transformation of the State Grid.

China's development is "worthy of pride"

Securities Times reporter: How do you evaluate the status quo of the development of clean energy in my country? What is the international level?

Shu Yinbiao: It can be said with pride that China's renewable energy development has led the world's renewable energy development. China is a country with a relatively rapid development of clean energy and a relatively large total amount of development.

At the beginning, our goal was very clear. By 2030, the installed capacity of renewable energy will exceed the installed capacity of thermal power by more than 55%. Build a clean, low-carbon, safe and efficient energy system, and carbon emissions will reach its peak by 2030, including the commitment to address the Paris climate change agreement. Our policy incentives are also lasting and appropriate.

In terms of scale and speed, China is now a country with a relatively large scale of renewable energy. The current installed capacity of renewable energy has reached 650 million kilowatts, accounting for 36.6% of the installed power generation capacity of the entire system. Renewable energy power generation accounted for 26.4% of the total power generation. Among them, photovoltaic and wind power have grown by 27% for five consecutive years, with considerable speed and scale.

What is more gratifying is the development in technology and industry. Not only does it occupy a place in my country's strategic emerging buckle casing industry, it has reached the world's advanced or even leading level in many aspects. For example, wind power can realize independent research and development of the entire industry chain, and photovoltaic power generation has mastered the core technology. In the past, inverters were completely imported. Now they can not only be independent, but also can go abroad and deploy overseas.

Securities Times reporter: Can you tell us what the State Grid has done to promote the development of clean energy in China?

Shu Yinbiao: my country's energy development model is different from that of the West. In recent years, the button casing market has also made a series of innovative breakthroughs.

First, in terms of the scale of clean energy development, relying on the "big power grid" to develop clean energy. By the end of last year, China's installed hydropower, wind power, and solar power generation capacity reached 340 million, 160 million, and 130 million kilowatts, respectively. The installed capacity of clean energy from the State Grid exceeded 490 million kilowatts, making it the largest grid of clean energy grids in the world.

Second, in the large-scale utilization of clean energy, it has overcome the core technologies of large-scale grid integration, control and consumption of clean energy. In June last year, it was realized in Qinghai to meet the province's electricity with renewable energy for 7 consecutive days. The difficulty of operation and duration have exceeded foreign practice, creating a new record of 100% clean energy power supply. In Hebei, we have built a large-scale demonstration project integrating wind, solar, storage and transportation in the world.

Third, in terms of UHV power transmission, the State Grid has fully mastered the long-distance large-capacity UHV transmission technology. There are 22 UHV projects in operation and under construction. The accumulated power transmission exceeds 900 billion kWh. A large amount of clean energy is passed through the UHV power grid. The northern part of the west is continuously transported to the eastern part. Overseas, Brazil’s beautiful landscape station project adopts ±800 kV UHV DC transmission technology, which is a demonstration project of "UHV + clean energy" in Latin America. The power demand of 22 million people.

I think it is necessary to have core technical advantages and turn technical advantages into standard advantages. In recent years, it has focused on strengthening the formulation of international standards in the fields of UHV, new energy grid-connected, smart grid, etc., initiated the establishment and preparation of 51 international standards, and the international standards such as new energy access that led the preparation of international standards are important norms for global related engineering construction; I have served as the vice chairman of the International Electrotechnical Commission (IEC) since 2013 and directly lead the work of the IEC Marketing Strategy Bureau.

Securities Times reporter: You talked about the relevant international standards in the field of clean energy. What is the current situation of my country's overseas deployment in this field?

Shu Yinbiao: We predict that by 2025, global investment in renewable energy alone will exceed US$2.6 trillion, which is not a small number. China now has a large number of photovoltaic and wind power equipment exported to foreign countries, and has cost and technical advantages in overseas energy infrastructure construction, and the cost performance is also high. If further development is combined with international standards, the competitiveness will be even stronger.

Specific to the State Grid, countries along the “Belt and Road” have strong demand for electricity, and the per capita installed capacity and electricity consumption levels are relatively low. I think the construction of power infrastructure has become a very active area in the construction of the "Belt and Road". The technology, equipment, and management of the State Grid are very competitive in terms of infrastructure construction capabilities. There are still 1 billion people in the world who do not have access to electricity. We must follow the concept of "a community with a shared future for mankind" and accelerate the promotion of a clean global energy transformation to achieve power poverty alleviation and mutual benefit.

Power generation and consumption are "two sides of the coin"

Securities Times reporter: Many clean energy sources are intermittent and unstable. What is the current situation of the “three abandonment” problems of abandoning water, wind, and light?

Shu Yinbiao: The "three abandonments" issue is a very unreasonable phenomenon. On the power generation side, electricity is generated through clean energy; on the power consumption side, electricity must be able to replace coal to provide power, and cars must use electricity to replace gasoline. These are two aspects of the same coin, which are complementary to each other. If you don't use it, it will be discarded. Therefore, China also needs to increase the level of final energy consumption.

Our development speed is too fast, and the consumption of clean energy is a challenge in China. We are both a large base and distributed power sources, and we are taking the road of "developing a large base, relying on a large power grid, and integrating into a large market." There are many tens of millions of kilowatts of wind power bases and photovoltaic bases in the west, and major hydropower bases in the southwest can be developed smoothly. If it is not used up locally, it will be transported to the east to form a nationwide pattern of consuming clean energy. Therefore, we must develop UHV. In addition, we have developed smart grids and used advanced power transmission technologies in some friendly wind farms.

Through active exploration and joint efforts of all parties, the curtailment rate of wind power and solar power generation has been "double-declined" in 2017. I think that after another year, the rate of abandonment of wind and light will drop from double digits to single digits.

Securities Times reporter: How do you think that under the current situation, how to overcome the "three abandonments" of clean energy?

Shu Yinbiao: The State Grid Corporation of China has this responsibility to ensure that clean energy is "deliverable, affordable, and usable", but it also depends on the joint efforts of the entire society.

di 1. Carry out overall planning at the government level to unify the connection of large renewable energy power generation bases, large power grids and market demand. Strengthen sticky end belts and policy guidance, and implement systems such as green certificates and renewable energy quotas.

The second is to speed up the infrastructure construction of the "big power grid" at the enterprise level. The nationwide consumption of clean energy requires a large power grid platform. Therefore, it is necessary to speed up the launch of a batch of trans-provincial and trans-regional UHV power transmission projects to improve the power transmission capacity from west to east. Strengthen the interconnection of power grids and expand the scale of interconnection. At the same time, strengthen thermal power peak-shaving transformation and system peak-shaving capacity building, carry out technological research such as large-capacity energy storage, and improve system balance adjustment ability.

The third is to give play to the role of market mechanisms. When we discussed the research, we found that at least 20% of the "three abandonments" came from market barriers. Therefore, it is necessary to build a unified national power market, break down barriers between provinces, and promote the consumption of clean energy across the country.

More importantly, it is necessary to improve the level of power consumption in the terminal energy and promote "re-electrification." At present, electricity accounts for 21% of the final energy consumption, which is at the international advanced level. Vigorously promote and encourage the use of clean energy at the social level, actively promote the use of electricity to replace coal and electricity to replace oil, and continuously improve the level of electrification in economic and social development.

"Re-electrification" promotes the energy revolution

Securities Times reporter: At the two sessions this year, you suggested to formulate and implement a re-electrification strategy at the national level. Can you further interpret the meaning of "re-electrification" for us?

Shu Yinbiao: From the perspective of energy production, re-electrification is reflected in the development and utilization of more and more new energy sources such as wind and solar energy through conversion into electricity; from the perspective of terminal consumption, it is reflected in the deep substitution of electric energy to fossil energy, such as electrified transportation Large-scale development.

With the application of electric drive, electric heating, electric heating and other facilities, the intensity of substituting electricity for coal and electricity for oil in civil, industrial, commercial, construction, and transportation fields will increase. The process of energy production and consumption revolution is essentially a process of re-electrification.

Through the implementation of clean heating and the construction of port shore power, the State Grid Corporation has promoted more than 100,000 projects to replace coal and oil with electricity, completing 360 billion kilowatt-hours of electricity. For example, a family in Beijing needs to burn three or four tons of coal in one heating season. After changing to electric heating, 4,000 kilowatt-hours of electricity is used in a winter, which is equivalent to about two tons of coal after conversion, saving energy consumption by about 50%, which not only improves energy efficiency and reduces pollution, but also saves costs and makes it convenient for the people.

Securities Times reporter: How to adapt to and lead the "re-electrification"?

Shu Yinbiao: A better society in the future will be a highly electrified society. In order to further promote the development of energy transformation and enhance my country's international competitiveness in the clean field, it is necessary to adhere to the power-centric, grid-based platform, and the goal of improving the level of electrification.

Specifically, it is necessary to strengthen unified planning, coordinate the promotion of energy structure adjustment and layout optimization, coordinate the connection between clean energy development, transmission and demand, and coordinate the promotion of market mechanism construction, network platform construction, peak shaving capacity construction and key technologies Tackling key problems. In particular, it is necessary to focus on the role of the grid’s energy conversion hub and basic platform, accelerate the improvement of a strong and smart grid with UHV as the backbone grid, create a wide-area ubiquitous, open and shared energy Internet, and improve the ability to optimize the allocation of energy resources for clean energy. Large-scale grid-connected consumption and electricity replacement of other terminal energy sources provide strong support. It is estimated that in 2030, my country's clean energy power generation installed capacity will account for about 55% of the total installed capacity, and the share of electricity in the final energy consumption will increase to about 30%.
