Front-line action ▶ ▷ Visit enterprises to solve the puzzle of "orderly electricity use"
Sustainable economic development is inseparable from a safe and efficient energy system and strong and reliable power support. From this point of view, to ensure the use of electricity in the industry is to ensure the stability of Foshan's economic chassis.
According to Ou Jingyuan, manager of the power supply service center of Foshan Shunde Power Supply Bureau, Shunde's manufacturing industry is developed, and the orderly implementation of electricity consumption by 49 large enterprises with an industrial output value of more than 1 billion yuan will greatly affect the orderly electricity consumption implementation rate. In recent days, the relevant departments of the Shunde District Government and the joint power supply departments of the town and street governments have visited 49 key enterprises such as Midea, Liansu and Xinbao Electric Appliances, listened to the opinions and suggestions of enterprises, and guided enterprises to consciously participate in orderly electricity consumption while fully coordinating and solving the problems of enterprise production and orderly electricity consumption, so as to ensure the safety of people's livelihood and power grid.
Different from the situation in Shunde District, there are about 69,000 existing industrial enterprises in Nanhai District, and the proportion of small and medium-sized enterprises is particularly prominent, which puts forward higher requirements for the deployment and monitoring of orderly electricity consumption.
In the early days, some small and medium-sized enterprises did not adapt to the rhythm of orderly electricity consumption. In order to help enterprises solve production problems, Wen Hongyuan, a technician in the second shift of the customer service team of the Danzao Power Supply Institute of Foshan Nanhai Power Supply Bureau, has been running on the front line of inspection for 5 consecutive months, and strives to understand and familiarize each enterprise's willingness to use electricity. For enterprises with a high degree of cooperation, the Danzao Power Supply Institute will give priority to notifying enterprises to resume normal electricity consumption when the power supply is relatively sufficient, thus forming an incentive mechanism.
"We are not to 'one size fits all' to limit the use of electricity by customers, but to reasonably guide customers to use electricity in an orderly manner and ensure the use of electricity for people's livelihood and public services." Du Yiyan, director of the Power Supply Service Center of Foshan Nanhai Power Supply Bureau, introduced.
The establishment of all flexible regulation and control mechanisms depends on the real situation collected during visits and inspections. In Luo Village, since May this year, the people who have taken the initiative to participate in the inspection are not only law enforcement personnel from the administrative department, but also volunteers from various villages and communities.
Not only to expand the front-line "fresh force", foshan Nanhai Power Supply Bureau Luocun Power Supply Station also adopts the strategy of "policy publicity and invitation to come in, supervision and reminder to go out", linked with the Luocun Social Management Office, and held an orderly electricity use conference for major chambers of commerce and associations in the jurisdiction, creating a good start for orderly electricity use actions.
Fine management ▶ ▷ Make good use of sufficient power supply capacity to maintain production capacity
"In the past few months, our orders and production capacity have basically not been affected, and there is an increase compared with last year." The relevant person in charge of Guangdong Fudi Auto Parts Co., Ltd. said. Fudi Automobile is a key automobile production enterprise recognized by the National Development and Reform Commission, and during the implementation of orderly electricity consumption, Fudi Automobile's electricity consumption reached 8.7 million kilowatts, an increase of 23% year-on-year.
The phenomenon of increasing production of Foday Automobiles is not an isolated case. Under the new situation of power supply, Foshan Power Supply Bureau accurately implements policies and group management, makes good use of power supply capacity, and ensures the production needs of enterprises.
This is first and foremost reflected in the formulation and implementation of policy programmes. Li Jun, manager of the power supply service center of Gaoming Power Supply Bureau, introduced that on June 10 this year, the bureau effectively guided 1713 production enterprises in the jurisdiction to scientifically and reasonably carry out orderly electricity use in accordance with the "Orderly Electricity Consumption Plan for Gaoming District from 2021 to 2022" revised by the District Development and Reform Bureau.
Zhang Li is a special manager of new energy and demand side management of the Power Supply Service Center of Gaoming Power Supply Bureau, and has been responsible for the orderly use of electricity since September this year. "In order to achieve power load curve monitoring during non-working hours and enterprise implementation monitoring, we have set up a special class for orderly power consumption work in the bureau." Zhang Li introduced that the members of the special class are mainly responsible for the load monitoring of the whole district during non-working hours, and timely release the orderly electricity consumption situation, which is one of the characteristic practices of the bureau to ensure that the monitoring service is in place.
Quality service ▶ ▷ "one enterprise, one policy" to maximize efficiency
By providing personalized services for different units, Foshan Power Supply Bureau supports major scientific research projects without stopping.
Jihua Laboratory is one of the first four provincial laboratories in the province, since the start of construction has made major breakthroughs, overcome the "card neck" problems including high-power microwave power supply and RADIO frequency power supply, scientific research projects have applied for 534 invention patents, 142 have been authorized, and scientific research achievements have been at the forefront of laboratories in the province. On October 19, the relevant personnel of Foshan Power Supply Bureau and Guicheng Power Supply Institute visited Jihua Laboratory.
Due to the need to carry out a number of high-tech research and development work, Jihua Laboratory has a large number of precision scientific research equipment, and the requirements for power supply guarantee are more stringent. Many projects require 24-hour uninterrupted power supply to ensure the success rate and accuracy of the experiment, at the same time, the experimental site has strict requirements for temperature and humidity, and the operation of related equipment also requires stable power supply.
"For Jihua Laboratory, we implement stable, reliable and uninterrupted power supply." Xu Chaohui, customer manager of Guicheng Power Supply Institute of Foshan Nanhai Power Supply Bureau, introduced that the external power supply adopts a "double circuit" power supply mode, if one power supply is cut off, the other power supply will be able to ensure power supply; at the same time, the design review service is provided for the internal power room setting of Jihua Laboratory to ensure the stable operation of facilities.
In the new generation of super-resolution spectroscopy detection science and technology research and development department of Jihua Laboratory, Wang Chenhui, a postdoctoral fellow at the station, introduced that the team mainly carries out the detection of organic semiconductor electroluminescent materials, the instrument is precise and the cost is high, once the middle can not be stopped, otherwise it will cause greater losses to equipment and materials, requiring the maintenance of a highly stable power supply voltage. "The team has been stationed for nearly a year, and the power supply has been very stable, and we are also very relieved." She said.
Entering the peak period of "Golden Nine Silver Ten" orders, the demand for electricity used by enterprises is more exuberant. Combined with midea group production plan, Foshan power supply Shunde bureau set up a special person responsible for midea group orderly power coordination and communication work, establish a normal communication mechanism, and coordinate production arrangements between various business units in real time. "We also assist Midea Group to participate in market-oriented demand-side response, and at the same time declare electricity consumption and orderly electricity subsidies for municipal, district and town governments at all levels, so as to obtain certain economic benefits while responding to orderly electricity consumption." Zhou Zhuoming, director of the Beijiao Power Supply Institute of Foshan Shunde Power Supply Bureau, said.
Foshan Gaoming Power Supply Bureau went deep into 64 key enterprises in the region to understand user demands, and the monthly electricity consumption in September increased by 4.83% year-on-year, ensuring the production of enterprises to the greatest extent.

Orderly use of electricity to know more points
First, what is the orderly use of electricity?
According to the Measures for the Administration of Orderly Electricity Use by the National Development and Reform Commission, orderly use of electricity refers to the management of controlling part of the electricity demand in accordance with the law and maintaining the order and stability of electricity supply and consumption under the circumstances of insufficient power supply and emergencies. The competent department of government electric power operation is responsible for the orderly use of electricity within the administrative region, and the power grid enterprise is the main body for the implementation of the orderly use of electricity, and the power users shall support the implementation of orderly electricity consumption。
In layman's terms, orderly electricity consumption mainly refers to staggering the electricity consumption of different users during peak periods of electricity consumption. According to the load characteristics of the power grid, part of the load during the peak period of power consumption of the power grid is transferred to the trough period of electricity consumption through administrative, technical, economic and other means, so as to reduce the peak-to-valley load difference of the power grid, optimize the allocation of resources, and improve the safety of the power grid. The implementation of orderly electricity consumption is also to ensure that the people's livelihood and public services during the peak load period of the power grid are not affected.
Second, why should we implement orderly electricity consumption?
(1) The temperature in Guangdong continues to rise. Since May this year, Guangdong Province has continued to be hot and arid, with temperatures reaching as high as 34°C-38°C, 3°C-4°C higher than the same period in previous years. According to empirical calculations, for every degree of temperature increase, Foshan's electricity load will increase by about 300,000 kilowatts. Under the "barbecue" model, Foshan's electricity demand continues to rise.
(2) The momentum of economic development is strong. Since the beginning of this year, Foshan's electricity demand has maintained rapid growth. From January to September, the power supply increased by more than 14% year-on-year.
(3) Insufficient primary energy supply。 Fuel prices are high, resource supply is tight, "quantity is small and high price", and power generation capacity is hindered.
Third, the orderly use of electricity cannot be confused with planned power outages
A planned power outage is not an orderly use of electricity. In order to ensure the safe and stable operation of the power grid, it is necessary to conduct a "regular physical examination" of the power supply equipment, and during the "physical examination" period, it is necessary to implement a planned power outage for the power supply equipment. However, now basically all the planned power outages, the power supply department will choose more forms and technologies of power supply and live operations to minimize the impact on residential users, and strive to make the public "zero perception" of the planned power outage.
Power supply enterprises in any country or city need to plan power outages, because planned power outages are the needs of ensuring everyone's production and life, and they are also part of daily power supply work. According to the relevant regulations, the planned power outage is preset in advance, and the power supply department implements the planned power outage to inform the user in advance.
