The consumption of renewable energy from the hotte

The "difficult consumption" of wind power and photovoltaic renewable energy has become the focus of the CPPCC National Committee

Abstract: by 2020, China's non fossil energy consumption will account for about 15% of primary energy consumption, and by 2030, it will reach about 20%. This is the solemn commitment of the Chinese government to the international community, highlighting the image of a large country in negative development, and also a concrete embodiment of the five development concepts of innovation, coordination, green, openness and sharing

on the one hand, the state greatly encourages the substitution of new energy and adjusts the energy structure; on the other hand, a large number of wind, light and water are abandoned in some areas of the new energy field

in the first year of the 13th five year plan, China's wind power, photovoltaic and other clean energy continued to maintain a steady development trend. In 2016, the proportion of clean energy consumption increased by 1.7%, which is different from the General Research Institute point, and the proportion of coal consumption decreased by 2%, but the optimization of energy structure is bound to be full of twists and turns, accompanied by pain. In recent years, some regions have abandoned wind, light and water on a large scale, and the adjustment of energy structure and the transformation of power market have entered a deep-water period of "climbing over the ridge"

clean energy has been abandoned on a large scale, which has become the focus of attention of the representatives and members during the national two sessions this year. Recently, the population, resources and Environment Committee of the CPPCC National Committee formed a special research group to carry out research in relevant regions to understand the deep-seated reasons behind the "three abandonments" and actively make suggestions and suggestions for solving the problem of clean energy consumption

clean energy has developed rapidly

after the continuous policy promotion since the "Eleventh Five Year Plan", China's clean energy has developed rapidly from scratch. According to the data provided by the national energy administration to the research group, by 2016, the total installed capacity of clean energy in China had reached 591 million KW, the combined installed capacity of wind power was 146 million KW, and the installed capacity of photovoltaic power generation was 78 million KW, all of which ranked first in the world

the vigorous development momentum has led to the increasing role of clean energy in promoting the adjustment of energy structure, achieving a wide range of incremental energy substitution and regional stock substitution. The proportion of coal consumption has been declining, and the proportion of coal consumption in 2016 has decreased by 6 percentage points compared with 2010

at the same time, the technical level of clean energy industry has also been continuously improved, and the cost has decreased significantly. In 2016, the cost of wind power in some regions of China has reached 0.47 yuan/kWh. Some experts predict that by 2020, the realization of parity of wind power has become a probability event

the lack of consumption capacity highlights

however, behind the rapid development of the clean energy industry, the problem of clean energy consumption has gradually emerged due to the impact of development imbalance, lagging reform and the lack of policies and systems

the situation of wind abandonment, which has lasted for many years, is still worsening. According to the data of the national energy administration, the wind power abandoned in 2016 reached 49.7 billion kwh, four times that of 2014. Among them, it is mainly concentrated in Gansu, Xinjiang, Inner Mongolia, Jilin and Heilongjiang. The waste air volume in recent three years is close to 80billion kwh, which is equivalent to the power consumption of Tianjin in 2015. Meanwhile, the wind abandonment rate in Gansu Province soared from 11% in 2014 to 43% in 2016

wind power is difficult, and photovoltaic life is also difficult. Relevant statistics show that in 2016, the amount of light discarded in the five northwest provinces (regions) alone reached 7.042 billion kwh, with a light rejection rate of 19.81%. Among them, the light rejection rate in Xinjiang is as high as 32.23%

in addition, the phenomenon of water abandonment that has lasted for many years has not shown signs of improvement. According to the introduction, the waste water is divided into normal waste water and abnormal waste water. Due to different statistical caliber, the data are different, but it can be determined that the abnormal waste water in the southwest reached a new high in 2016, with a loss of more than 70billion kwh, which is close to the annual power generation of the Three Gorges power station

it is particularly noteworthy that as the former base load power supply, nuclear power also encountered the embarrassment of power reduction and low price last year. Qian Tianlin, member of the National Committee of the Chinese people's Political Consultative Conference and director of the science and technology and Information Department of China Nuclear Power Group, said, "due to various factors, nuclear power cannot be fully developed. Last year, 46.2 billion kwh of electricity was lost due to the abandonment of nuclear power nationwide." This loss of electricity is equivalent to about 1/5 of the country's nuclear power units shut down throughout the year

on the one hand, there is the rapid development of clean energy installation, and on the other hand, green power is wasted. Clean energy urgently needs to get out of the cycle of "installing more, discarding more"

only the right medicine can be given

the right prescription can cure the disease. What is the root cause behind the massive abandonment of clean energy

the research team learned that all kinds of clean energy are abandoned, and the factors are different, but they also have their commonalities. First, power demand slows down; Second, local and nearby consumption is limited; Third, the delivery channel is limited

"to develop the economy, electric power should take the lead. For a long time, the growth of electric power has been planned according to. 5 percentage points higher than the growth of GDP. Previously, the growth of GDP was in the double digits, but now the growth of GDP has slowed down, and the growth rate of China's economic operation has entered a new development platform. Under this condition, the power capacity formed in the past will show a total surplus." Lu Qizhou, member of the CPPCC National Committee and former general manager of China Power Investment Group, said

Zhangjiakou is one of the regions with the most abundant wind and solar energy resources in North China. The exploitable amount of wind energy is more than 40million kW, the exploitable amount of solar energy is more than 30million kW, and the annual output of various biomass resources reaches 2million tons. Since 2003, wind power and photovoltaic enterprises have been deployed here. Today, the installed capacity of wind power has reached 8.14 million KW, and the installed capacity of photovoltaic power generation has reached 2.6 million KW. However, abundant wind power resources are subject to the transmission capacity of power channels. In 2016, the abandoned wind power reached 1.6 billion kwh, and the abandoned wind rate exceeded 1. 0% will be implemented this year. "Zhangjiakou has limited capacity to absorb renewable energy. Despite our efforts, local consumption accounts for only 35% of the city's power generation. Most of the electricity needs to be sent to Beijing, Tianjin and Hebei for consumption, but the existing three export channels are far from meeting the development needs of renewable energy." Wuweidong, mayor of Zhangjiakou, told the research group

the research team learned that in Northwest China, where wind and light are most seriously abandoned, Gansu and Xinjiang are the most serious. Mainly affected by export capacity. At present, Gansu is mainly transmitted through two 750 kV high-voltage AC lines, with a transmission capacity of about 3.3-4.3 million KW, and is shared with Xinjiang and Qinghai. The capacity of new energy power transmission channels is very limited

in the past two years, the installed capacity of hydropower in Southwest China has increased rapidly, with a sharp transition from dry to wet, increasing the pressure on hydropower stations to take into account flood control and power generation. In addition, the relatively concentrated precipitation in the flood season and the insufficient capacity of the export channel also exacerbated the abandonment of water to a certain extent

Shi Yubo, member of the National Committee of the Chinese people's Political Consultative Conference and former deputy director of the national energy administration, pointed out that the verification of the power generation plan and start-up mode of a large number of coal-fired power units in China is unscientific, the incentive policies for auxiliary services are not in place, the formulation and assessment mechanism of the inter provincial interconnection line plan is unreasonable, the compensation and regulation capacity across provinces and regions can not be brought into full play, and the demand side response capacity is restricted by the rigid electricity price policy, Many factors lead to the failure to effectively tap the system's ability to absorb clean energy

in addition, a problem that cannot be ignored is that stimulated by the national subsidy policy for new energy, some regions did not consider the consumption capacity, resulting in the "great leap forward" in the development of new energy. "At present, the installed capacity of wind power in some provinces (regions) in the 'Three North' has exceeded the 2020 planning target." Chen Yongsheng, a researcher from the comprehensive office of the new energy department of the national energy administration, said

subsidies are overburdened

it is understood that the new energy industry is highly dependent on financial subsidies, and its own development momentum is insufficient. With the rapid development of the industry, the gap of financial subsidies continues to expand, and the current subsidy policy is unsustainable

according to statistics, the subsidy intensity of photovoltaic power generation, wind power generation and biomass power generation in 2016 was 0.55 yuan, 0.21 yuan and 0.27 yuan per kilowatt hour (KWH), respectively, and the subsidy demand for the whole year reached 80billion yuan

the huge subsidy scale is funded by the renewable energy electricity price surcharge. Since 2006, the state has imposed additional renewable energy tariffs on electricity sales nationwide. In 2016, the state raised the tariffs from 1.5 cents/kWh to 1.9 cents/kWh

in fact, since 2012, due to various factors, there has been a funding gap in subsidy funds every year, and it has expanded year by year

only know that insufficient maintenance subsidies have become an important problem restricting the development of renewable energy. It is learned that at present, some local governments and renewable energy enterprises do not understand the current funding gap of renewable energy subsidies, but still aim at financial subsidies and try to find various ways to start projects

promoting consumption requires comprehensive measures

"although the phenomenon of" three abandonments "has occurred in some areas of China, it must be recognized that this is a temporary phenomenon in some areas, and the general direction of developing clean energy must be adhered to." Shi Yubo, member of the CPPCC National Committee and former deputy director of the national energy administration, emphasized

Shi Yubo said that promoting the consumption of new energy is a systematic project, which requires the joint participation of government departments, power enterprises, power generation enterprises and users, and comprehensive measures

Lu Qizhou believes that in addition to planning, technology and other factors, the large-scale abandonment of clean energy is directly related to the fact that the existing power market system does not adapt to the development of clean energy. On the one hand, there is an excess of power capacity relative to GDP growth, on the other hand, there is a structural shortage relative to consumer demand. In the context of the slowdown in power demand, it just makes room for the optimization and adjustment of power structure. "The simultaneous abandonment of clean energy such as wind, light, water and nuclear energy is a systemic problem, which requires systematic optimization of the whole power and energy."

Lu Qizhou suggested that we should speed up the construction of a unified national power market, gradually release the development plan of power consumption, integrate the trading mechanisms of power generation rights and direct trading into the power market system, and completely liberalize inter provincial transactions. More importantly, we should strictly follow the national energy and power planning goals of the 13th five year plan, fully consider the consumption capacity, and develop new energy in an orderly manner

Shi Yubo suggested that it is necessary to strengthen the unified planning of power, orderly guide the construction of new energy projects, strictly control the new coal-fired power in the eastern and central regions, pay close attention to the construction of transmission channels, start the preliminary work of a number of urgently needed UHV key projects, and speed up the construction. In addition, we will fully implement electric energy substitution, vigorously develop electric vehicles, and encourage users to actively participate in power demand side response and market transactions

Wang Zhaohai, member of the CPPCC National Committee and former vice political commissar of the Navy, suggested that the new energy subsidy policy should be adjusted as soon as possible and a market-oriented consumption mechanism should be established as soon as possible

Qi rang, a member of the CPPCC National Committee and deputy director of the population, resources and Environment Committee, suggested that we should strengthen scientific and technological innovation and, in view of the characteristics of renewable energy and the needs of the economy and society, lay out the situation of scientific and technological research and development and the distribution of slippage in related industries, which will make emerging industrial clusters represented by renewable energy a new pillar of economic growth

"by 2020, China's non fossil energy consumption will account for about 15% of primary energy consumption, and by 2030, it will account for about 20%. This is the solemn commitment of the Chinese government to the international community, highlighting the image of a major country in negative development. It is also a concrete embodiment of the five development ideas of innovation, coordination, green, openness and sharing. The current problem of new energy consumption is a problem in development, and it can be solved as long as the measures are on the right path." Zhang Jiyao, head of the research group and deputy director of the population, resources and Environment Committee of the CPPCC National Committee, said
