Economic Information Daily reported on May 15 that the Southwest region represented by Sichuan and Yunnan is the “main battlefield” of China’s hydropower development “. However, in recent years, under the double pressure of the rapid growth of hydropower installed capacity and the continuous downturn of the growth rate of electricity consumption, Sichuan, Yunnan and other major hydropower provinces have continuously “abandoned water” for many years, resulting in a large amount of clean energy wasted in vain, the Enterprise suffered serious losses and the tax on resources and land dropped sharply. Actively developing hydropower is an important means to optimize the energy supply structure and increase the proportion of non-fossil energy consumption in China during the “Tenth Five-Year Plan” period. Some insiders suggested that clean energy allocation should be firmly implemented “a game of chess for the whole country”, and the increasingly severe contradiction of “abandoned water” should be resolved through specific policies and measures to ensure the healthy development of the hydropower industry. The situation of abandoned water caused by supply-demand imbalance is severe Sichuan and Yunnan are the regions with the most abundant hydraulic resources in our country, and they are also the important power bases of China’s “West-East Power Transmission. A batch of national major hydropower projects such as Xiluodu, Xiangjiaba and Jinping (Level I and Level II) were successively established and started construction during the “Tenth Five-Year Plan” and “Eleventh Five-Year Plan”, and were put into production in the “Twelfth Five-Year Plan, the supply capacity of clean energy in Sichuan-Yunnan region has been greatly enhanced. According to the data from Sichuan Energy Bureau, during the 12th Five-Year Plan period, the installed capacity of Sichuan hydropower increased by 18.1 percent annually, which is equivalent to putting into operation a Three Gorges power station every two years. However, as the macro-economy enters a new normal, the demand for electricity will slow down, and the contradiction between electricity supply-demand imbalance will gradually become prominent. The electricity consumption of the whole society in Sichuan dropped sharply from the double-digit growth level in 2011 to-1.1% in 2015, which was also the first negative growth in Sichuan since 1998. In recent years, the installed power generation capacity of Yunnan hydropower and other clean energy sources has increased rapidly, and the power supply capacity has been greatly improved. However, influenced by the macroeconomic situation and institutional mechanism, since 2013, the province’s power supply has changed from seasonal abundance and deficiency to annual surplus, especially a large number of hydropower abandoned water in flood season. Statistics from the Yunnan provincial industrial and information commission show that during the “Twelfth Five-Year Plan” period, the power installed capacity in Yunnan province increased rapidly, and the total power installed capacity in the province increased from 36 million kilowatts in 2010 to 79.15 million kilowatts in 2015, in the past five years, the total new installed capacity is about 43 million kilowatts, with an average annual growth rate of 17%. By 2016, Yunnan’s hydropower installed capacity had reached 60.96 million kilowatts, and hydropower and other renewable energy accounted for of the province’s total installed capacity. Contrary to the rapid growth of power installation, influenced by the macroeconomic situation, the growth rate of Yunnan’s electricity demand slowed down in the late 12th Five-Year Plan, and the disconnection between power development and construction and the cultivation of electricity market was obvious. The phased surplus of electricity supply directly led to the gradual expansion and intensification of “abandoned water” of Southwest hydropower. The reporter learned from the energy authorities and power grid enterprises in Sichuan and Yunnan that in 2013, Sichuan and Yunnan “abandoned water” was 2.6 billion and 5 billion kWh respectively; Last year, the “abandoned water” of the two provinces has reached 14.2 billion and 31.4 billion kWh respectively, while 30 billion kWh is equivalent to the electricity consumption of the whole society in Hebei province for one month. According to relevant estimates, this year, under the condition that the thermal power of Yunnan power grid is operated in a minimum mode and only 16 billion kWh of power generation is arranged, the surplus power of hydropower may still be nearly 55 billion kWh. Contradiction between water and electricity transmission and absorption The reporter investigated in Sichuan and Yunnan and found that this round of “abandoned water” was directly caused by the imbalance of power supply and demand in stages, but behind it were many contradictions existing in the ability and mechanism of cross-regional allocation of clean energy. The first is that the installed power generation has increased rapidly. The electricity consumption and external load in the province are less than the installed capacity, and the contradiction between the supply of electricity and the demand is prominent. At present, the installed capacity of power generation in Yunnan is 84.43 million kilowatts, and it is estimated that the installed capacity will be about 87.2 million kilowatts by the end of this year. However, the maximum load of electricity consumption and external delivery in the province is less than 50 million kilowatts, and the installed capacity of the province exceeds 362.7 billion kWh, the province’s electricity consumption and delivery plan demand is 260.2 billion kWh, and the province’s electricity surplus is 102.5 billion kWh. The surplus power of hydropower is nearly 55 billion kWh. New energy pressure intensifies. In 2017, the new energy installed capacity in Sichuan will still grow rapidly. It is expected that the new energy installed capacity will exceed 3 million kilowatts by the end of 2017, and the annual electricity capacity will reach 6 billion kwh. The problem of new energy consumption in Sichuan will become more prominent. Due to the difficulty of absorbing new energy outside the province, the coordinated development of various clean energy sources in Sichuan is becoming more and more prominent. Secondly, water and electricity transmission faces “price trap”. According to relevant sources, due to the prominent contradiction between electricity supply and demand, it has become a buyer’s market. After market-oriented transactions, the electricity price of hydropower enterprises is generally lower than the original on-line electricity price, which cannot fully reflect the value of clean energy such as hydropower. At the same time, the investment in hydropower construction cost, immigration, environmental protection and so on is increasing, and the competitive advantage of hydropower in the oversupply market is becoming smaller and smaller, and the sustainable development of hydropower industry is facing challenges. In 2016, cross-provincial and cross-regional transactions in Sichuan province were carried out in a market-oriented way for the first time. In the annual transaction, the outbound price of power generation enterprises is 0.21 yuan/kWh, and the price is lower than the price of water and electricity in the receiving provinces and cities, which is nearly 0.03 yuan/kWh lower than the year-on-year. The temporary transaction price is as low as 0.16 yuan/kWh. According to relevant sources, the decline in the price of outbound electricity did not bring additional outbound electricity growth. From the actual outbound electricity in Sichuan province, the year-on-year decline was (in 2015, including the transfer electricity from Jingguan to Liuchuan, the price is higher than the price sent by Sichuan). Obviously, the market mode cannot promote the absorption of clean energy. Third, the Southwest hydropower transmission channel is seriously insufficient and the progress is slow. At the end of the “Twelfth Five-Year Plan”, Sichuan’s cross-provincial and cross-regional power exchange capacity has reached 28.5 million kilowatts, ranking first in the provincial power grid in the country. However, compared with Sichuan’s power installed capacity of more than 80 million kilowatts and the provincial load of nearly 30 million kilowatts, the delivery capability is still insufficient. During the “tenth and Third Five-Year Plan” period, Sichuan was only approved for a 500 kV third channel project of Sichuan-Chongqing power grid, with a maximum delivery capacity of about 2 million kilowatts. However, Sichuan is expected to increase its power installation capacity by 20 million kilowatts during the same period. Therefore, it is a foregone conclusion that the “abandoned water” area of Sichuan province will continue to expand in the “tenth and third five-year plan. Fourthly, under the condition of imbalance between supply and demand and obstruction of delivery, it is also difficult to absorb electricity locally. According to statistics from the power security department of Yunnan Provincial Industry and Information Technology Commission, due to the macroeconomic situation, during the “Twelfth Five-Year Plan” period, the growth rate of electricity demand in Yunnan province declined year by year, with an average annual growth of 7.47%, lower than the growth rate of installed power generation and power generation, in 2015, the electricity consumption of the whole society in the whole province showed negative growth for the first time, down year-on-year, and continued to decline in 2016. The electricity consumption of the whole society in 2016 was about 5 billion kWh less than that in 2013. The main reason was the decline of industrial consumption. In Sichuan, the average electricity load in the province is only more than 1/3 of the installed power generation capacity in the whole province. Although the electricity consumption in Sichuan exceeded 200 billion kWh last year, the growth rate reached a new high in nearly three years, but it also failed to reverse the situation of “abandoned water. Fifth, the willingness of central and eastern regions to accept Southwest hydropower has weakened. Liu yang, deputy director of the development planning department of state grid sichuan electric power company, told the reporter that the fourth uhv dc transmission channel in sichuan had been put forward in 2013 and was included in the “tenth and third five-year plan, it is planned to send power from the middle reaches of yalong river to a certain provinces in the central region, but this line was opposed by the provinces where the project was delayed. At present, two hydropower stations have been built in the middle reaches of Yalong River, but the delivery channel and the consumption market are not clear, and there is a serious disconnection. Chen Yunhui, deputy general manager of State Grid Sichuan Electric Power Company, analyzed that with the changes of economic environment and supply and demand situation, the central and eastern regions were under the pressure of increasing taxes and promoting employment, they prefer to use local thermal power rather than accept foreign hydropower. Clean energy development needs a national game of chess” Insiders suggest that in view of the fact that most hydropower resources are far away from China’s load center, we should continue to adhere to the strategy of “sending electricity from west to east” and introduce practical measures from the policy level, implement clean energy allocation “a game of chess across the country”. The first is to coordinate and coordinate the construction of various regions and various energy sources, and gradually increase the proportion of non-fossil energy consumption. At present, Sichuan and Yunnan provinces have introduced measures to strictly control medium and small hydropower projects. Shi Yudong, general manager of Sichuan Electric Power Company of State Grid, believes that it is necessary to guard against some areas blindly relying on energy investment to stimulate the economy, especially energy projects with short construction cycle, so as to avoid “rushing up”. The second is to get through the “obstruction” of cross-regional power transmission as soon as possible “. Under the condition that the trans-regional power transmission capacity is obviously insufficient, the channel construction should be started as soon as possible; Inter-Provincial barriers should be broken and trans-regional power transmission should be put to a higher level for coordination; Strict measures should be introduced to ensure the network, SOURCE synchronous planning and construction, and require new projects to implement market space in advance to prevent the occurrence of new “abandoned water” phenomenon. The third is to improve the system and mechanism of clean energy development. The Ministry of Industry and Information Technology of Yunnan province suggested that the state implement differentiated policies when assessing the total energy consumption and the reduction rate of
