1.88 million kilowatts, which is the province of Hunan. In the second quarter, when thermal power was operated in a minimal way, only six units were able to run on capacity. In the second quarter, most thermal power units in Hunan were stopped.
In the first half of the year, Hunan Province's 12 unified thermal power plants completed a total of 2,410.41 million kilowatt-hours of power generation, representing a year-on-year decrease of 15.3%. The actual completion rate was only 33.79%. The completion of the power plant's integrated power plant plan was generally unsatisfactory.
While the completion rate of power generation is relatively low, the utilization hours of 600,000 kilowatts in Hunan Province are 318 hours less than the utilization hours of 300,000 kilowatts, and the utilization hours of large and small units in Hunan are seriously inverted.
Why Hunan's thermal power suffered such a situation?
Inadequate demand for water and thermal power to operate in a minimal way In fact, in the first half of the year Hunan's hydropower generated 23.583 billion kwh, an increase of 41.07% over the same period last year.
In order to fully absorb hydropower resources and use clean energy, Hunan's thermal power generation is operated in a smaller or minimal way. In May and June, most of the thermal power units in Hunan are in shutdown and are mainly operated by 300,000 kilowatt-class units. Most of the 600,000 kilowatt-class units have been shut down for a long time.
However, “the weather is not good for the publicâ€, when the hydropower was large and the power supply was sufficient, in the first half of this year, the electricity consumption of heavy industry in Hunan Province also decreased slightly year-on-year. Correspondingly, the electricity consumption of the entire society in Hunan Province in the first half of the year 65.05 billion kwh, an increase of 5.69% year-on-year, which is 6.09 percentage points lower than the growth rate in the first half of 2011.
Under the background of the large economic downturn pressure in China, the growth rate of electricity consumption in Hunan is obviously slowing down, and electricity demand, especially that of heavy industry, is weak.
It is worth noting that, with the exception of the previous two months, the average assessment completion rate of the annual thermal power project in Hunan Province was only 17.16%, and the completion rate was 27.23%. The lowest is only 9.53% of the power plants, a difference of 14.51 percentage points; and the maximum positive and negative deviations of the completion rate of assessment among the power plants are 11.06 and 6.63 percentage points respectively.
Why does the integrated thermal power plant in the same province have such a large gap in the completion rate of power generation assessment? After experiencing the “wounding pain†that once the coal price was high, causing the power plant to have no money to buy coal or even coal shortages, in order to encourage coal-fired power companies to actively adjust coal and electricity, Hunan’s provincial power planning and power generation were conducted two months earlier this year. The scheduling arrangement implements the principle of “coal power generationâ€, which means that thermal power operation is basically adopted, thermal power plants with more coal reserves can generate more power, and thermal power plants with relatively less coal reserves generate less power. The actual amount of power generated by each thermal power plant was not included in the balance of the annual power generation schedule.
In addition, a large number of thermal power plant centralized maintenance is one of the reasons for the large deviation in the completion rate of power plant power generation plans. In the first half of the year, a large number of thermal power units were scheduled to be overhauled. The overhaul unit involved 24 units of the 12 centralized power plants in the province, and the maintenance capacity was 8.695 million kilowatts, which accounted for 54.0% of the province's total thermal power capacity.
Multiple measures to ensure the smooth completion of the annual power generation plan to reduce the progress gap of the power plant power generation schedule as soon as possible to ensure that the completion of the annual power generation plan assessment completion rate is basically the same goal, Hunan Electric Power Supervision Office proposed to strictly in accordance with the "triple public" dispatch of the SERC The requirements of the transaction put forward specific regulatory requirements from the aspects of strengthening the supervision of dispatching, the supervision of power generation rights trading, the supervision of trans-provincial power transmission channels, and the supervision of network interface.
In the area of ​​dispatch supervision, the Hunan Electric Supervisory Office believes that the current situation must be closely followed by the weather. At the end of the determination of the peak water period, the power plant with a backward schedule will be given priority to start and take over if the safety mode is not lower than the minimum requirement for safety and stability of the power grid. Load; Considering that the power plant may affect the power generation progress balance due to overhaul or modification, the Hunan Electric Power Supervision Office proposes to balance the progress of power generation. Priority will be given to large power plant units with similar schedules, and priority will be given to medium and large power plants in the same power plant. After the power plant, ensure that the plan is balanced and reasonable.
With regard to the problem of severely inverting the utilization hours of 600,000-kilowatt and 300,000-kilowatt turbines, the Hunan Electric Supervisory Office stated that in the coming period, the power generation rights trading will be deepened to promote the replacement of low-efficiency, backward-looking small generating units with high-efficiency and large-scale environmental protection units. Utilization hours of large units.
The annual utilization hours of 600,000 kilowatt-class units were higher than 300,000 kilowatt-class units to promote the implementation of energy-saving and emission-reduction policies. In addition, in respect of trans-provincial power transmission channel supervision, it is necessary to make full use of trans-provincial power transmission channels and to flexibly use market-based measures to promote the timely and efficient use of wealthy water in a wider range; Dry mix, multi-source complementary; use the advantages of large-scale power grid interconnection to implement power emergency support and important power protection.
The Hunan Electronics Regulatory Office stressed that it is necessary to conscientiously implement the various regulatory systems on the factory network interface, improve the power trading information reporting and disclosure system, and promptly do a good job in the preparation of transaction contracts, related agreements, and transaction execution to ensure power trading.†Fair and open".
