Into September, the total electricity consumption 1 / 3 of the residents use of air conditioning load is greatly decreased summer peak period should end. However, Shanxi, Guangxi, Zhejiang, Guizhou, Hunan and other places are currently still in a serious power shortage situation.
Hunan Provincial Committee by letter that the maximum power shortage during summer peaks of 500 million kilowatts, accounting for 25% of electricity demand. Hunan in September still on electricity shortfall of about 2.5 million kilowatts. Total daily power shortage of 400 million kwh.
Reporters learned that,glue gun while coal shortage, the provinces are difficult to supply, on the other hand, because of drought is still severe, resulting in hydro power generation capacity is insufficient.
"Fire and water are not enough."
And most of the provinces and cities across the country have bid farewell to the peak period. In Hubei, for example, to August 21, the province's electricity consumption will drop to 400 million kwh less, only 383 million kwh. Prior to August 18, had reached 476 million kwh of electricity on a new record.
However,glue stick in most provinces after a period of steady through the summer peaks, including Hunan, Guangxi, Guizhou, Zhejiang, Shanxi and other places continued tension power broke the news.
Currently, the Hunan Daily, 250 million kilowatts of electricity shortage, Zhejiang, is 200 million kilowatts, and Guangxi in June broke 100 million kilowatts of electricity shortage, and currently has 400 million kilowatts of that gap.
Hunan Power Grid Power Exchange Center senior Ouyang Yongxi told reporters in the past Hunan hydropower and thermal power is the proportion of 1:1, the proportion of thermal power has increased in recent years, but the reduction in hydropower generation, thermal power and can not keep up, it is inevitable not problem.
Guangxi Electric Power Industry Association, told reporters that experts Lin Bin, a lot of water to power in Guangxi in the Yunnan-Guizhou Plateau, in Yunnan, Guizhou are relatively drought, reservoirs in Guangxi less, thus less power.
For example, in the Red River area in Guangxi Longtan Hydropower Station, the planned total installed capacity of 6.3 million kilowatts, but the drought has caused water levels drop, the current power generation capacity can only keep about half. Impact of drought in July, Guangxi Longtan Power Station Red River water levels, power generation only completed in July, 900 million kwh, down 44.3%, on a serious impact on the overall economy. The amount of hydro power in Guangxi region, also fell more than 20%.
"If sufficient reservoir of water, power shortage should not be in Guangxi." September 8, Lin Bin, told reporters of the power shortage situation of Guangxi, said, "Go over there to buy water from Qinhuangdao coal too far, even the way the railway far, only to buy coal in Guizhou, Guizhou, but also very nervous now, plus the price is not low, to buy coal from Vietnam are also facing higher prices situation. "
Earlier, deputy chief engineer Gu Nanfeng Guangxi Power Grid Corporation has revealed that the original power shortage is expected to Guangxi's largest dry season until the fourth quarter to appear, the results of this year's Red River has suffered the biggest since records began in hydrological drought, runoff is only the usual current year 30%, so that Guangxi Hydropower generation output is equivalent to the level of the dry season than last year's 5 million kilowatts down 2.5 million kilowatts, a 50% reduction.
Southwestern part of the runoff by 75%
National Development and Reform Commission's report, this year, except June, the national average annual precipitation over the same period were Pianku. Affected, year on year growth of hydropower generating capacity was rapidly falling. Hydropower generating capacity in July, 69.8 billion kwh, down 11.2% since March last year, the biggest decline a month; chain increased by only 5.1%, lower than the average level in recent years (10%).
Sub-provinces, in July Fujian hydroelectric power generation fell 56%, down 40.7% in Hunan, Zhejiang, down 31%, down 30.8% in Guizhou, Guangxi, Guangdong, Chongqing, more than 20% decline.
