Since this summer, Jiangsu electric power “neural” stretched very tight. On July 7, tracking maximum power load in the province reached 47.27 million-kilowatt, and 1.65 million-kilowatt increased the maximum load than last year. 8th, tracking daily electricity consumption reached 1.01 billion kWh, upon the first broken 1 billion-kilowatt mark. 11 provincial government tracking of electricity load of record. Relevant persons said, the end of the first peak load largely because for a number of days of thunder storm and Typhoon “Phoenix” brings cool. In this peak period, the province has been hundreds of distribution line loaded or overloaded, old district of Nanjing was forced to the 10,000-volt line article 3 of the provisional road.
8 month 4th weather, power load rebound. 7th, the Commission called the maximum load 44.71 million-kilowatt in the whole province. Province electric power company official said that currently available generation resources in Jiangsu Province, highest power supply capability to meet 52 million-kilowatt needs, but uncertainty about power supply and demand balance. If the rise of temperature, load, and district power supply capability gaps may occur in the province. 2000 appear at peak load on September 3 time. For electricity supply, and taut nerves still sensitive.
about 90% in Jiangsu Province are coal and electric power, coal consumption in the province more than 80% by the outward redeployment. In a sense, dominate the fate of coal into electricity supply in Jiangsu Province.
this year coal “rations” constraints stand out, the difficulties of “unprecedented”. First of all, resources, and after entering the hot season, the province’s coal inventory fell to record low, Ligang power plant, sheyanggang power plant main electric power plant coal stock in less than three days, some unit outages due to coal shortages. Second, prices, in May, the Datong coal mixing in Qinhuangdao port offers up to 690 dollars a tonne, than the beginning of last year rose more than 150 million. Third, poor quality, the calorific value of coal power plant purchases only 3,000 calories, the province’s generating capacity by 100,000-kilowatt and above the coal quality is limited. Four is the transportation difficult, high concentration of coal resources in China make outgoing channels capacity has become tighter, in parts of Jiangsu sea to River power plant in Qinhuangdao port loading for a long time, coal supply is affected.
tightening of domestic coal prices rose, makes power plant production cost has improved significantly. Countries adjusted the electricity price, power plant once for losing about 5 cents up losses of 9 cents. Data show that profits of over $ 5.8 billion last year, the province’s main power plant, and serious losses in the first half of this year. Industry sources said, now mainly rely on State-owned power plant in social responsibility, using technological innovation to increase output, reduce expenditure digestive part of the added costs, wages have been reduced for a power generation company 30%.
ease supply pressure, from the perspective of the current, you can increase the external coal procurement, encourages power plant generating and strengthening management to improve the efficiency of electricity use and doing well, such as energy saving and consumption reducing, as for enterprises, financial subsidies may be granted.
but, as energy consumption big province, Jiangsu Province the growing contradiction between energy demand and relative shortage of energy supplies will persist, through restructuring of power energy sustainable development is a long-term move. This adjustment has at least two aspects, first of all is the adjustment of industrial structure, industry accounted for about 81% of Jiangsu electric power consumption, primary industry and tertiary industry accounted for about 9%. Calculation shows that proportion of the tertiary 1%, II 1%, unit GDP energy consumption can be reduced 1%. By means of rigid guide and promote the accelerated celebrity wedding dresses development of modern service industries, advanced manufacturing industry. Huizhou in Guangdong this year since February, high-energy consuming industries in peak Valley price $ 0.2 per unit based on fare increases. Followed by optimizing the energy structure itself. Electric power industry in our province’s 60% of the total primary energy consumption, energy restructuring potential is huge. On one hand we must vigorously develop new energy sources like nuclear power, solar photovoltaic. Particularly solar PV, the province is the production of a province, but the in-place conversion rate is very low, which required appropriate policy support. The other hand, thermal power plants also have to upgrade. Provincial development and Reform Commission estimates, “pressure on small” can bring the province’s electric power construction 4 million-kilowatt of space. Premise total State control, us should have more as. (Shao Shengyu)
