In recent times, policy measures such as coal dispatching and transportation, electricity price market-oriented reform, and dual energy consumption control have been stepped up ——
Alleviation of "power cuts" in many places
Precise control can show results

"Cumulative electricity consumption is 1453320 kWh, cooling capacity is 1624.60 MWh..." The reporter walked into the Chint Group Industrial Park in Yueqing, Zhejiang a few days ago and saw a string of data constantly beating on the digital screen, and the company's real-time energy consumption situation It's clear at a glance.
In Wenzhou, the local government has taken the lead in building an energy data center, which has been connected to about 8,000 companies and has achieved the aggregation of more than 100 million energy data such as electricity, carbon, oil, and gas.
With the help of big data "portraits", we can accurately identify energy-saving renovation projects that "energy saving of more than 30 tons of standard coal per year, energy consumption per unit of added value decreased by more than 4%, and labor productivity of all employees increased by more than 20%", and subsidized based on the amount of project investment .
Facing the tight power supply situation, Zhejiang played a set of precise energy control combination punches.
Zhou Weibing, director of the Zhejiang Provincial Energy Bureau, said that since the beginning of the year, Zhejiang’s economy has recovered well, but energy consumption in various regions has increased rapidly and increased, especially in high-energy-consuming industries. The situation of dual control of safety and energy consumption brings challenges.
To this end, according to the progress of dual energy consumption control, Zhejiang has adopted a series of measures such as energy budget management for high energy-consuming enterprises, orderly use of electricity, and off-peak production.
Recently, many localities and enterprises have established and improved digital control and monitoring platforms to implement precise policies and systematic control to effectively alleviate energy constraints in an orderly manner.
Huang Xiaoyao, general manager of State Grid Zhejiang Electric Power Company, stated that Zhejiang Electric Power has first launched the "Industrial Carbon Efficiency Code" and "Photovoltaic Navigation" and other power service products for energy saving and consumption reduction in the country, so that enterprises have a clear understanding of their own energy consumption levels. ", and organize account managers and carbon efficiency engineers to go to factories and enterprises to provide full-process energy-saving transformation and energy-efficiency improvement services.
In addition, closely follow the power supply and demand situation and the dual control of energy consumption, coordinate power generation companies to ensure the power generation capacity in Zhejiang Province, further optimize the power grid peak winter plan, and adhere to the power grid safety line and the bottom line of civilian power consumption.
"We strengthen collaboration with power supply companies, conduct investigations and studies on large energy users one by one, fully consider factors such as safety production, employee employment, contract performance, and upstream and downstream industries, and implement precise policies and scientifically implement energy consumption dual control target requirements." Zhou Weibing Said that Zhejiang does everything possible to protect the reasonable production and energy demand of enterprises, and try to avoid sports-style energy-saving and carbon-reduction behaviors.
The multi-pronged approach shows results.
Experts suggest that for regional short-term power gaps, effective use of existing coal power production capacity, fully tapping the demand side potential, and optimizing power grid dispatching should be used to cope; In order to increase the efficiency of energy conservation and the use of renewable energy, the power limit should be replaced by carbon control instead of energy control.
In the long run, we should further strengthen the construction of multi-energy complementary clean energy, vigorously develop energy storage, optimize cross-regional power transmission, and adopt a combination of distributed and centralized energy use methods to fill the power gap in time.
Reduce the operating pressure of power generation companies

"Through the joint efforts of all parties, the power supply situation in the province has been alleviated, and the power consumption in Guangdong Province has been basically guaranteed since the National Day." On the 10th and 26th, the relevant person in charge of the Power Department of the Guangdong Energy Bureau told reporters.
Since the beginning of this year, Guangdong's economy has continued to recover, and electricity demand and load have maintained rapid growth.
From January to September, the province’s total electricity consumption reached 602.5 billion kWh, a year-on-year increase of 16.5%.
Electricity load has maintained rapid growth. The province's highest unified load has hit a record high, and the highest load demand has reached 141 million kilowatts, an increase of 11% year-on-year.
Demand growth is an important reason for the electricity gap.
At the same time, in September, affected by the continuous high temperature weather, the superimposed primary energy supply shortage, high fuel prices, and the increase in generator set equipment defects, Guangdong experienced a large power gap, and some industrial enterprises were forced to implement orderly electricity use.
In response to this situation, Guangdong quickly established a dedicated work mechanism to ensure energy and power supply.
The responsible comrades of the Guangdong Provincial Energy Bureau said that in response to the high prices of coal and natural gas and the increase in the cost of power generation companies, Guangdong has introduced a series of measures such as the peak-valley time-of-use electricity price policy and the on-grid electricity price subsidy program during the peak summer period of gas power. It has also stepped up efforts to urge major power generation groups to restore the generating capacity of units to normal levels as soon as possible.
It is understood that Guangdong Power Grid Corporation actively coordinated the supply of electricity, coal and natural gas, tapped power supply capacity, improved the mechanism of power generation costs, arranged for power plants in the province to generate electricity according to the maximum capacity of the unit, and made an orderly power supply forecast, and implemented detailed user segmentation. , To protect people's livelihood and electricity for public services.
At present, Guangdong Province monitors power plants' coal storage and unplanned shutdowns on a daily basis, implements inventory management, and “clears” power plants that have less than 7 days of coal storage to urge power plants to restore power generation capacity as soon as possible.
At the same time, strengthen the supply of thermal coal resources, actively assist coal power companies to purchase coal, coordinate transportation departments to connect coal transportation capacity, and take multiple measures to alleviate the operating difficulties of power generation companies.
In addition, policies such as financial subsidies, tax deferrals, market transaction price increases, and gas power generation on-grid tariffs have been introduced to effectively alleviate the operating pressure of power generation companies.
Guangdong has also played its role as a large platform for resource allocation of China Southern Power Grid, and has made every effort to coordinate the increase in supply of Western Power, and send power to Guangdong according to its maximum capacity to increase the capacity of external power supply.
"Because of the continuous high supply of primary energy and the high price shortage and the low water period in western provinces, it is expected that the power supply situation in Guangdong Province will be relatively tight during this winter and next spring. We still need to do our best to ensure power supply." Guangdong Energy Bureau told Guangdong Power this winter and next spring. Make an analysis of the supply and demand situation.
At the same time, it is proposed that the next step will be to strictly observe the bottom line and resolutely protect the energy use of people's livelihood and the energy use of key guarantee objects.
Guaranteed coal supply

Since the end of September, the implementation of orderly electricity consumption in Liaoning Province has been further strengthened, and the Liaoning power grid has no longer been subject to power rationing, ensuring the safe operation of the large power grid and power consumption for people's livelihoods.
In order to guarantee the power supply this winter and next spring, the State Grid Liaoning Electric Power Co., Ltd. has determined 20 power supply guarantee measures for power grid dispatching, safe operation, and scientific and technological guarantee.
The company constantly improves and revises emergency plans, adheres to the bottom line of “no power cuts without opening the gate”, resolutely guarantees people’s livelihood, public services and important users’ electricity use, and establishes a dispatching system to ensure power supply emergency mechanism and a special task team, so that it is responsible for keeping the land. Conscientious.
At the same time, we will coordinate and optimize the arrangement of the power grid operation mode, accelerate the construction of key projects for the peak winter, and make all preparations for the peak winter.
In addition to power companies, the railway sector has also taken strong measures to ensure power supply and heating.
China Railway Shenyang Bureau Group Co., Ltd. has given full play to its role as the backbone of railway coal transportation and launched a special campaign to ensure coal supply for power generation and heating in the Northeast.
At present, 70 coal trains depart from 20 coal loading points within the management of Shenyang Bureau Group Corporation every day and are transported to major power plants in the northeast region.
The relevant person in charge of China Railway Shenyang Bureau Group Co., Ltd. stated that since October, the company has established a coordination mechanism with relevant government departments of Liaoning Province, Jilin Province and Inner Mongolia Autonomous Region to set up special accounts to implement matters such as coal sources and transportation capacity guarantees.
All freight centers and relevant stations and depots work with relevant local government departments and key coal-using companies to establish a daily communication mechanism to implement red line management for power plants that can store coal for less than 7 days.
Vigorously implement "one enterprise, one policy" and "one matter, one discussion", pay close attention to the coal market situation, formulate supply organization and transportation plans for key coal production enterprises and customers by region, and have signed cooperation agreements with 15 key coal production enterprises.
As of October 18, the coal inventory of 64 power plants under the management of Shenyang Bureau Group Company was maintained at 5.464 million tons, and the number of days that could be spent increased from 13 days at the beginning of the month to 20 days.
Recently, 18 Liaoning coal-fired power units with a total of 6.15 million kilowatts were shut down and temporarily checked for coal-fired power generation.
The relevant person in charge of the Liaoning Provincial Development and Reform Commission said that the next step will be to strengthen the province's coal mine scheduling and implement a weekly production report system.
Comprehensively investigate potential safety hazards, prevent production shutdowns due to safety issues, which will affect the coal supply in the province, and stabilize the basic coal production in the province.
Strictly control the use of energy-intensive coal other than coal for power generation and heating, and guide cities in the province to prioritize high-energy-consuming enterprises on the list of discontinuable coal users.
When supply and demand are tight during the heating season, the first step is to reduce the use of coal by high-energy-consuming enterprises.
