21st Century Business Herald reporters Wang Fan and Chen Jie Shenzhen and Foshan reported on the electricity situation in Guangdong, the largest economic province, which has aroused widespread concern.
Some prefectures and cities have launched an orderly electricity consumption plan, using "open three stops and four stops" to stagger the peak of electricity. However, the heads of enterprises in different cities told the 21st Century Business Herald reporter that thanks to good communication with the local power supply department, the company has formulated an orderly power consumption plan, and the impact of power rationing on production is basically within the controllable range, and some enterprises said that "the impact on the completion of orders is within 5%."
It is worth noting that the current round of staggered peak electricity consumption in Guangdong Province is not because of the dual control of energy consumption, but mainly because of the strong economic recovery, coupled with the double growth of the electricity load caused by high temperatures. At the same time, in the case of high prices of natural gas and coal, the power generation capacity of units inside and outside the province has continued to decline.
Guangdong Province and various cities have adopted a series of measures, including ensuring the supply of thermal coal, supervising and urging power plants to do a good job in the reserve of power generation fuels and auxiliary materials, making every effort to coordinate the increase of supply of western electricity, transmitting electricity to Guangdong according to the maximum capacity, and increasing the supply capacity of foreign electricity.
It is understood that under a series of "open source and throttling" measures, at present, the power shortage situation in the province has been effectively alleviated.
Experts also expect that with the efforts of all parties, with the implementation of a series of measures, the power supply tension is expected to gradually ease.
<h4>Power rationing is not due to "dual control of energy consumption"</h4>
Blue Arrow Electronics Co., Ltd. (Foshan) is a professional R & D manufacturer of semiconductor devices, from the situation in previous years, generally from September to the entire fourth quarter is the best time for business. However, this year, due to the better control of the domestic epidemic situation, overseas demand for Chinese semiconductors is strong, and the order volume of Blue Arrow in the first 8 months is also very sufficient.
This is a microcosm of the strong economic recovery momentum in Guangdong Province. According to data from the Guangdong Provincial Bureau of Statistics, from January to August, the added value of industries above designated size in the province was 2.32 trillion yuan, an increase of 14.4% year-on-year, an average growth of 5.6% in two years; exports were 3.18 trillion yuan, an increase of 19.1% year-on-year, and an average growth of 7.6% in two years.
The steady and rapid development of the economy has led to the rapid growth of electricity, of which, in January and March, the electricity load in Guangdong's history exceeded 100 million kilowatts, and the growth rate of electricity reached more than 30%. From January to August, the electricity consumption of the whole society in Guangdong Province was 525.273 billion kWh, an increase of 17.33% year-on-year, of which the electricity consumption of the secondary and tertiary industries increased by 18.30% and 23.13% respectively.
At present, it is the peak period of "Golden Nine Silver Ten" orders, especially the demand for electricity in secondary and tertiary production continues to be strong. Recently, Guangdong Province's staggered peak electricity consumption arrangement is about 15 million kilowatts, and this round of peak shifting once reached 24 million kilowatts during the high temperature of the double typhoon.
High temperatures are another important influencing factor.
According to the Guangdong Provincial Energy Bureau, since the beginning of September, under the influence of the double typhoons of subtropical high pressure, "Kangsen" and "Candu", Guangdong Province has continued to be high temperature and drought, and the average maximum temperature in the province has reached 34.4 °C, which is 2.2 °C higher than the same period of the year. Under the "barbecue" model, The demand for electricity in Guangdong Province continues to rise, and as of September 23, the maximum load demand of the province has reached 141 million kilowatts, an increase of 11% over the highest load last year, and the load has reached a record high.
As a typical temperature -sensitive area, Guangdong has recently reached a maximum temperature of 34-38 °C, and for every degree of temperature increase, the electricity load will increase by 2-3 million kilowatts.
Behind the high growth of electricity demand, the superposition is a tight power supply situation.
The information obtained by the 21st Century Business Herald reporter from the Guangdong Provincial Energy Bureau shows that the prices of natural gas and coal are high, the supply of resources is tight, and the enthusiasm of thermal power enterprises for power generation is not high. Recently, the maximum power generation capacity in Guangdong Province has dropped by nearly 30 million kilowatts, accounting for 20% of the province's installed capacity, which is the main reason for the recent power supply shortage.
Is there a relationship between guangdong's round of power curtailment and dual control of energy consumption?
Liu Wensheng, deputy director of the Guangdong Provincial Energy Bureau, said that this round of staggered peak power consumption is mainly caused by factors such as the double growth of high temperature "blessing" power load and the limited power generation capacity of units in the province, not because of the dual control of energy consumption. Guangdong Province adheres to the dual control of energy consumption in accordance with laws and regulations, avoids the "one-size-fits-all" approach, and adopts measures such as suspension of work, suspension of production and rectification of "two high" projects such as unapproved construction in accordance with laws and regulations; when there is a shortage of power supply, give priority to ensuring the use of electricity for residents' daily life and service industries, and focus on restricting the use of electricity by "two high" enterprises.
<h4>The impact of the enterprise is controllable</h4>
Under the influence of power curtailment, what impact have enterprises in Guangdong Province been affected?
Zhang Guoguang, deputy general manager of Blue Arrow Electronics Co., Ltd. (Foshan), told the 21st Century Business Herald that in general, the power supply company will notify the power outage time in advance, and only in a few cases will receive the power outage notice when going to work.
"At present, we are quite satisfied with the whole because the local power supply authority has full communication with us. In the future, we also hope to continue to maintain this state of communication, so that we can find more ways to overcome difficulties internally. Zhang Guoguang said.
Zhang Guoguang also mentioned that the better point is that it is generally not a power outage 24 hours a day, and the time that needs to be blackout is normally daytime, generally from 8 am to 10 pm. Since our company is a "three-shift" work system, if the power is not cut off at night, you can rush back some orders at night. When the power is limited, it will still be guaranteed in terms of lighting and other aspects, and the company will also maintain the standby state of the equipment.
"Overall, the impact of power rationing on the completion of our orders is about 5%." Zhang Guoguang said.
Guangzhou Honda Automobile Company also replied to the 21st Century Business Herald reporter that the current production and sales rhythm of Guangqi Honda has not been affected by the power supply. The company will actively adjust the production arrangements flexibly and other ways to ensure the normal production order.
Zhang Jianzhong, director of Shenghong Technology (Huizhou) Co., Ltd., introduced, "Before the implementation of orderly electricity consumption, the staff of Guangdong Huiyang Power Supply Bureau of China Southern Power Grid communicated and negotiated with us many times and formulated an orderly power consumption plan for us. After learning about the orderly electricity consumption plan and requirements, the factory area adjusts different production lines and scheduling methods in a targeted manner to ensure that the output and product quality are not affected. ”
A person in charge of an enterprise in Shunde, Foshan, told the 21st Century Business Herald reporter, "At present, we are responding to power curtailment by providing our own generators, which can ensure basic production needs." The local Economic Promotion Bureau recently visited enterprises to understand the difficulties of enterprises and also provided relevant assistance. We are guessing that as we enter October, the situation of power curtailment will improve significantly. ”
<h4>Multi-pronged approach</h4>
At present, Guangdong Province and other cities are making every effort to take measures to actively cope with the recent shortage of power supply.
On September 26, the Guangdong Provincial Energy Bureau and Guangdong Power Grid Co., Ltd. jointly issued the "Proposal for The Orderly Use of Electricity and Save Electricity for Electricity Users in the Province", requiring party and government organs and institutions at all levels in the province to take the lead in setting an example and taking the lead in practicing green energy-saving office, the refrigeration temperature of air conditioning is set at not less than 26 ° C, the doors and windows are closed during air conditioning operation, the power supply of office equipment such as air conditioning during non-working hours is closed, and the use of elevators on 3 floors and below in office space is encouraged; it is recommended that industrial and commercial enterprises in the province actively participate in saving electricity. Support the implementation of orderly power consumption. At the same time, the general public is encouraged to adopt a moderately economical, green and low-carbon family lifestyle, make use of natural light as much as possible in home lighting, turn on fewer long lights, and encourage air conditioning to set the temperature not less than 26 ° C.
Bao Bo, power dispatching and control center of Guangdong Power Grid Company of China Southern Power Grid, introduced that Guangdong Power Grid has ensured the maximum power supply capacity through active coordination, every effort to tap the power supply capacity inside and outside Guangdong Province, and strengthen demand-side management.
In addition to demand-side management, various relevant departments are also making every effort to ensure the supply of electricity.
Bao Bo introduced, "We fully arrange power plants in the province to generate electricity according to the maximum capacity of the unit, and at the same time give full play to the overall advantages of the resource optimization platform of China Southern Power Grid Corporation, and actively strive for more power transmission between provinces." ”
The 21st Century Business Herald reporter learned from relevant people of Guangzhou Hengyun Group that in the first 8 months of this year, the company purchased 2.4 million tons of coal, up 17% year-on-year.
"In order to ensure power supply and heat supply, even if the market price rises from a stage low of 536 yuan / ton to the current historical high of 1500 yuan / ton (5000 kcal), we do not consider the cost, just to protect the lights of 10,000 homes, the average purchase price rose sharply by more than 80% year-on-year." Introduction of relevant people of Hengyun Power Plant.
According to the Guangdong Energy Bureau, on the power generation side, we will make every effort to increase the power supply, ensure the supply of thermal coal in Guangdong Province, supervise the main body of natural gas supply to ensure the supply of natural gas, meet the needs of the unit for power generation, and supervise the power plant to do a good job in the reserve of power generation fuel and auxiliary materials to ensure the stable and reliable operation of the unit during peak hours. Promote the construction of key power supply projects and transmission projects, ensure that projects are put into production on schedule, and increase supply capacity。
At the same time, organize power generation enterprises and power grid enterprises to strengthen the inspection and operation and maintenance of key equipment and lines, balance the maintenance arrangements of units, and ensure the safe and reliable operation of equipment. Give full play to the role of the Southern Power Grid as a large platform for resource allocation, make every effort to coordinate the increase in supply of western power, transmit electricity to Guangdong according to the maximum capacity, and increase the supply capacity of external electricity。
In the long run, Fan Yongchun, deputy chief engineer of Guangdong Electric Power Design and Research Institute Co., Ltd. and general manager of the Energy Consulting and Planning Institute, pointed out that Guangdong has vigorously laid out new energy power generation projects such as photovoltaic and wind power in recent years, and related projects are accelerating construction. China Southern Power Grid plans to basically build a new power system by 2030, with non-fossil energy accounting for more than 65%, and new energy will become the largest power source in the five southern provinces and regions.
