The 13th five-year plan period is a substantial and crucial stage in the transformation of China's energy consumption structure.Controlling total energy consumption is the top priority, while controlling total coal consumption is the top priority.As the core of modern energy system, power industry has always been the main consumption sector of coal, and also the key sector of greenhouse gas and pollutant emission.In the context of the new normal of the economy and the transformation of the energy system, it is the main goal of the power industry to strictly control the total coal consumption, promote the peak of coal consumption in 2013, increase the proportion of green energy consumption, and promote the optimal allocation and structural upgrading of power resources in the later period of the 13th five-year plan and even in the future.To achieve these goals, the key is to actively promote the power (especially coal power industry) supply side structural reform.Promoting supply-side structural reform is a major decision made by the CPC central committee and the state council, and a major innovation to adapt to and guide the new normal of economic development.In February 2016, nur bekri, director of the national energy administration, pointed out that to solve the prominent problems of energy development under the new normal, such as overcapacity in traditional energy, bottlenecks in the development of renewable energy and low efficiency of the overall energy system, we must innovate the energy system and mechanism and vigorously promote the structural reform of the energy supply side.In 2016, we completed the task of cutting coal production capacity by more than 250 million tons. At the same time, we planned ahead and halted or delayed the construction of a number of coal-fired power projects, making important progress.This report reviews the coal consumption control achievements of the power industry in 2017, quantifies the coal consumption and coal control of power generation in the current year by combining the power supply and demand situation and renewable energy consumption situation, and breaks down the coal control effects of various supply-side reform measures.Secondly, it studies and evaluates the characteristics of the new normal of power generation, looks into the situation of power supply and demand in the later period of the 13th five-year plan, and proposes and quantifies the coal saving potential of major supply-side reform measures, such as promoting demand-side management, strengthening the consumption of renewable energy, and improving energy efficiency through economic dispatch.The influence of thermal power flexibility reform, an important supply-side reform measure in the power industry, on the consumption of wind power connected to the grid is systematically analyzed.Finally, the report analyzes the supply and demand situation of the power industry in 2018, calculates the scale of power generation coal consumption, and puts forward several policy Suggestions for the structural reform of the power supply side and wind power consumption.In 2017, China's total public electricity consumption was 6.4 trillion kilowatt-hours, up 6.5% year-on-year and 1.5 percentage points higher than the same period last year.The electricity consumption of the secondary industry was 4441.3 billion kilowatt-hours, up 5.5% year-on-year, or 2.6 percentage points higher than that of the same period last year.The electricity consumption of the tertiary industry was 881.4 billion kilowatt-hours, a year-on-year increase of 10.7%, or 1.1 percentage points lower than that of the same period last year.The electricity consumption of urban and rural residents reached 869.5 billion kilowatt-hours, a year-on-year increase of 7.8%, or 3 percentage points lower than the same period last year.Table 1 shows the historical electricity consumption of each department.The growth rate of electricity consumption in 2017 was much higher than that of 2015 and 5% higher than that of 2016.The main reasons for the rapid growth of electricity consumption in 2017 are: the macro economy has maintained steady and moderate growth, the high temperature in summer, the rebound of high-consumption industries, and the rapid growth of the tertiary industry.2. Power consumption in high-consumption industries the growth performance of power consumption in 2017 indicates that the economy is stable and improving, but the growth trend of power consumption in high-consumption industries indicates that the effect of economic stimulus policies at the end of 2016 is withdrawing, and the growth of power consumption is expected to decline in 2018.As can be seen from figure 3, the growth trend of high power consumption industry is similar to that of the whole society.Since the fourth quarter of 2016, electricity consumption in the four high-consumption industries has increased rapidly, which has promoted the rapid growth of electricity consumption in the whole society.From January to November 2017, the growth rate of the four high-power consumption industries increased year on year.The total electricity consumption accounted for 28.9% of the total electricity consumption and 19.7% of the total power consumption growth.The total electricity consumption of the four high-consumption industries increased by 4.0%, with the growth rate falling quarter by quarter.With the exception of the chemical industry, growth in other high-power industries has slowed sharply in November.The market prospect of new coal chemical industry determines the uncertainty of chemical industry's continuous growth.Building materials and ferrous metal industry growth rate than the same period last year fell;Non-ferrous metal smelting industry electricity consumption and growth rate have declined.Cement and steel production has fallen slightly between January and November, based on electricity data.In the case of coal production, raw coal output fell 2.7 per cent in November from a year earlier, driven by low downstream production, and the demand factors expected to lead to a rebound in coal output due to a decline in thermal power generation were not present.The above analysis shows that by the end of 2016 economic stimulus policy reform the supply side, high power consumption industries, such as the price picks up, the intermediate links to fill inventory multiple factors driving the wave of high rebound is out of power industry, electricity consumption of 2018 and beyond, should pay more attention to the light industry especially high value-added manufacturing, the growth of the third industry and daily use.By the end of 2017, China's total installed power-generating capacity had reached 1.7777 trillion kilowatts, up 7.6% year-on-year.Among them, the installed capacity of non-fossil energy power generation was 690 million kw, accounting for 38.7 percent of the total installed capacity, an increase of 2.1 percentage points year on year.The installed power generation capacity of China increased by 133.72 million kw, of which 89.88 million kw was installed by non-fossil energy generators, both hitting record highs.Installed hydropower capacity increased by 12.87 million kilowatts, including 2 million megawatts of pumped storage.Added 15.03 million kw of grid-connected wind power;The newly installed grid-connected solar power generation capacity was 53.38 million kw, an increase of 21.67 million kw year on year.The installed coal and electricity capacity increased by 38.55 million kw, a year-on-year decrease of 1.42 million kw 2.China's full-caliber power generation capacity is 6.42 trillion kilowatt-hours, up 6.5% year on year;Among them, non-fossil energy generation increased by 10.0%, accounting for 30.4% of the total power generation, an increase of 1.0 percentage points year on year.The total grid-connected solar power generation, wind power generation and nuclear power generation increased by 75.4%, 26.3% and 16.5% respectively.
