South China's thermal power utilization hours upside down energy-saving dispatch still need to force

Recently, the 2013 Annual Electricity Regulatory Report of the Southern Bureau of Energy of the State Energy Administration (hereinafter referred to as the “Report”) was published, of which a considerable amount of space was disclosed for energy conservation and emission reduction.

The "Report" shows that the relevant energy regulatory agencies in the southern region have actively carried out special regulations for energy conservation and emission reduction in 2013, effectively promoting resource conservation and environmental protection.

China Southern Power Grid has achieved remarkable results in terms of comprehensive line loss, power coal consumption, and plant power consumption rate reduction. However, on the basis of comprehensive implementation of energy-saving power generation dispatching, due to factors such as the structure of the grid structure, the number of hours of use of coal-fired generating units and the equivalent load rate in some provinces and regions are different. There is more potential to be tapped.

The standard coal consumption for power generation is 302 g/kWh, and the commissioning rate of direct-control unit desulfurization facilities reaches over 90%.

The "Report" shows that in 2013, the comprehensive line loss rate of China Southern Power Grid was 7.20%, a decrease of 0.11 percentage points from the previous year; the standard coal consumption of power generation was 302 g/kWh, which was a decrease of 1 g/kWh from the previous year; plant electricity consumption rate It was 4.50%, a decrease of 0.05 percentage point from the previous year.

“The newly commissioned coal-fired units in the southern region have all installed and put into operation desulfurization facilities simultaneously.” The “Report” also disclosed that the direct-adjusted coal-fired units at or above the provincial level discharged a total of 244,000 tons of sulfur dioxide throughout the year. According to the online monitoring of environmental protection, the operation rate of the desulfurization facilities of the direct-adjusting units of the provincial-level dispatching agencies in the five southern provinces and regions has reached more than 90%; the number of units with the desulfurization efficiency of more than 90% has reached 256 units, accounting for direct-adjusting units of provincial-level or higher dispatching agencies. 98.1%.

In view of the above situation, the "Report" believes that all grid companies in the southern region can preferentially purchase renewable energy power; dispatching agencies at all levels optimize hydropower and wind and fire dispatch, and optimize cascade hydropower scheduling. No water discards or winds are found due to scheduling reasons throughout the year. Happening. According to statistics, in 2013, China Southern Power Grid acquired 299.8 billion kwh of hydropower, 9.43 billion kwh of wind power, and 146 million kwh of photovoltaic power generation. All these efforts have made a great contribution to the reduction of emissions.

In addition, through the implementation of power generation rights substitution, only Guangxi Guodian Yongfu Power Generation Co., Ltd. Yongfu Power Plant and Guangxi Fangyuan Electric Power Co., Ltd. Laibin A power plant, on fuel consumption to save 44,000 tons of standard coal, reduce carbon dioxide emissions 117,000 tons, reduce sulfur dioxide emissions 852.9 Ton.

From a regulatory point of view, the Southern Energy Regulatory Agency actively supports renewable energy sources such as wind, light, and hydropower.

To carry out special supervision of energy-saving and emission-reduction price stays, strictly supervise the implementation of the environmental protection electricity price policy, and carry out statistical work on wind-power and wind-reduction power, which has effectively promoted resource conservation and environmental protection. At the same time, the Southern Energy Regulatory Agency conducted a special survey on energy-saving and emission reduction in 2013, supervising and promoting the implementation of flue gas desulphurization and denitrification facilities for coal-fired units in Guangdong, Guangxi, and Hainan provinces, and eliminating the implementation of flue gas bypass work in desulfurization systems. The local government carried out environmental protection and eliminated backward production capacity, and urged the power supply companies to adopt power outage measures for 15 illegal discharge or elimination enterprises, effectively protecting the environmental rights of the people.

In addition, the Southern Energy Regulatory Agency continued to increase the supervision of energy conservation and emission reduction in the power industry from two aspects: on-line monitoring and on-site supervision.

The Southern Energy Regulatory Agency continued to play its role in off-site supervision and management. It comprehensively monitored and combed the information of the on-line monitoring system for coal-fired unit flue gas in 2013, notified the power generation company of the relevant conditions, and conducted power generation problems on the online monitoring data. The company conducts supervisory interviews and supervises them to strengthen the operation and management of desulfurization, denitrification facilities and on-line monitoring systems for flue gas.

In terms of on-site supervision, the Southern Energy Regulatory Bureau conducted inspections on the emission of flue gas pollutants from existing coal-fired power plants in Guangdong Province in May 2013, and monitored six major coal-fired power plants in the Pearl River Delta region for pollutant discharge monitoring. Prepare power plants for spot checks. All power companies actively cooperated and paid attention to the rectification work, and took measures from the management and technical means to meet the rectification requirements.

Over 40% of renewable energy installations are installed, and there is an upside down in the number of hours of use of thermal power units.

According to the "Report", by the end of 2013, hydropower installed capacity in the southern region was 93.10 million kilowatts, accounting for 41.0%; wind power installed capacity was 5.17 million kilowatts, accounting for 2.3%; solar power generation installed capacity was 284,000 kilowatts, accounting for 0.13%, and the three accounts for 43.43% cumulatively. In 2013, hydroelectric power generation in the South Region was 285.7 billion kwh, an increase of 7.99%; wind power generation was 8.9 billion kwh, an increase of 42.57%; solar power generation was 174 million kwh, an increase of 184%.
