Make every effort to promote the resumption of work and production, increase supply and expand sales, and improve power supply capacity and service quality

"Improving quality and efficiency is an effective means to cope with the current severe business situation, and it is also a strategic measure to stimulate the endogenous motivation of enterprises and achieve high-quality development." On April 18, the 2020 Second Quarter Working Conference of State Grid Co., Ltd. (hereinafter referred to as the "Second Quarter Meeting") was held. Mao Weiming, Chairman and Party Secretary of State Grid Co., Ltd., mentioned the term "quality improvement and efficiency improvement" many times at the second quarter meeting.

Faced with the extremely severe business model, State Grid Co., Ltd. vigorously implemented quality and efficiency improvement actions, and through reasonable growth in quantity and steady improvement in quality, it has made a balance and effort between reducing social energy costs and achieving sustainable development of the power grid, improving efficiency and preventing risks.

In recent years, the macro economy has declined and the growth rate of electricity has slowed down. At the beginning of this year, the COVID-19 epidemic broke out. The epidemic prevention and control measures and the long holiday broke the regular trend of electricity consumption in the whole society of my country. The electricity consumption continued to hover at a low level, which had an impact on the power industry chain.

If you respond well, danger can turn the opportunity. Today, State Grid has vigorously carried out market development to improve quality and efficiency, and has made important progress in key tasks of market development. In the first quarter of this year, the State Grid vigorously increased supply and expanded sales, implemented more than 7,000 power substitution projects, and completed 32.1 billion kilowatt-hours of replacement electricity; actively received water and electricity supply areas, improved service levels, promoted people's livelihood and the economy to develop healthy power demand, and stimulated the growth of electricity demand.

Solve real problems and respond to real needs. State Grid has taken multiple measures to increase supply and expand sales, which has expanded profit growth points while also allowing enterprises and residents to truly feel the benefits. The reporter learned from the second quarter that in the first quarter of this year, State Grid Co., Ltd. actively helped all types of enterprise users to resume work and production, provided "three zero" electricity service to 4,082 epidemic prevention and control enterprises, provided 11.5 billion yuan of low-cost and convenient inclusive financial services to more than 30,000 small and micro enterprises, and implemented "non-stop supply of arrears and no late payment fees" for 600,000 corporate customers.

"So much! The electricity bill has been reduced by nearly 2 million in two months, which has greatly alleviated our operating pressure!" Recently, Zhao Feng, the electrical director of TSMC (China) Co., Ltd., the world's largest chip manufacturing company, received an electricity bill. When he was told that he had enjoyed preferential electricity price policies in February and March, reducing electricity bills by 1.966 million yuan in total, he called the State Grid's measures to help enterprises resume work and production were indeed "powerful".

"Our production line is 24 hours a day and has always been the highest power consumption in the whole region. During the Spring Festival epidemic, although there were fewer employees on duty, due to the high automation of the production line, we ensured that the production line operated at high load through reasonable scheduling. The abundant and stable power supply makes the company worry-free production." Zhao Feng said, "This year, TSMC's production orders were very full, and the electricity consumption in January and February alone increased by more than 8% compared with the same period last year. After the full resumption of work and production in March, the electricity consumption surged by 12.7%!"

The reporter learned that in the next step, State Grid will continue to focus on the revolutionary opportunities of energy production and consumption, implement strategic deployments such as pollution prevention and control battles and rural revitalization, adhere to customer-centric, market-oriented, and efficiency-based guarantees, and help build a clean, low-carbon, safe and efficient modern energy system, and promote market development, quality and efficiency improvement to make new progress.

Implement key technologies and equipment research and development, implement classified policies to expand the breadth and depth of electricity substitution

"Some time ago, we transported glutinous rice balls and cinnamon-flavored lychees from Guangdong and Guangxi, and Chenzhou people also ate fresh fruits." Xie Guangle is the first batch of fresh tasters of the agricultural product cold chain in Chenzhou City, Hunan Province. After nearly 4 years of development, his Dada cold chain logistics company has basically formed a production line integrating picking, sampling inspection, rough processing, warehouse entry and delivery. It is the first 4A-level cold chain logistics enterprise in Chenzhou.

On the open space in front of Xie Guangle's factory, there are two 120-kilowatt charging piles, and 35 electric distribution vehicles are neatly placed next to it, solving the problem of the "last mile" of cold chain logistics distribution of fresh agricultural products. This is thanks to Hunan Chenzhou Power Supply Company tailored a set of electrical energy alternatives for the factory. Chenzhou Power Supply Company not only calculated the capacity of charging piles, promoted the implementation of green logistics for the company, but also inspected and inspected power lines and equipment during peak power consumption. If there is a planned maintenance task, the company will be notified to prepare for backup power supply as soon as possible to ensure the normal operation of the cold chain.

Not only Chenzhou, but across the country, State Grid Co., Ltd. is also continuing to promote agricultural and rural modernization construction, improve the power supply capacity and power supply reliability of rural power grids, release the potential for rural power substitution, promote new electrification equipment in agricultural product breeding, grain storage and other links according to local conditions, and accelerate the use of cold chain logistics, electroster sterilization, electric dehydration and other technologies, gradually extending the substitution field from agricultural production to agricultural product processing link.

In addition to agricultural production and sales, electricity substitution has also played a lot in the resumption of work and production of enterprises.

On April 3, the Tianjin Electric Power Science and Technology Innovation Center, mainly composed of State Grid Tianjin Electric Power Company Electric Power Company Electric Power Research Institute, organized a flexible technical team to conduct a comprehensive energy simulation test in the joint laboratory of electricity substitution technology. They used laboratory real-time simulation systems to conduct in-loop testing of secondary equipment widely used in the integrated energy system, and through tests on typical electrical energy substitution equipment such as heat storage electric boilers and heating cables, they comprehensively analyze the impact of equipment on the operation of the power grid and evaluate the energy efficiency level.

During the resumption of work and production, the flexible team of the Science and Technology Innovation Center has used the joint laboratory of electricity substitution technology to complete the experimental work of four typical electricity substitution equipment in Tianjin. Based on the start-up and operation characteristics of the electricity substitution equipment, it has deeply analyzed the impact of electricity substitution on the power supply capacity and equipment load level of Tianjin's power grid, and has accumulated practical experience in focusing on the analysis of the characteristics of different electricity substitution equipment and the optimization configuration of power supply schemes in typical scenarios after resumption of work and production.

In addition, the State Grid has continuously improved the price and compensation mechanism of electricity substitution, deepened research on the technology economy, service prices, subsidy policies, etc. of electricity substitution; improved the environmental protection policies for electricity substitution, promoted the introduction of support policies for alternative projects such as grain electric drying and cold chain preservation, and guided users to use electric kitchens; improved the market mechanism for electricity substitution, give full play to the role of the provincial comprehensive energy company as a market entity, and reduced the initial investment and operation costs of the project by introducing industrial funds, carrying out operating leasing, and energy custody and other market-oriented means, and promoted the implementation of the project.

In the next step, State Grid will focus on key areas such as transportation, industrial electric boilers, and coal-fired self-owned power plants, and accelerate the promotion of annual key projects for power substitution, ensuring that the replacement power in 2020 will reach 190 billion kilowatt-hours, an increase of 10 billion kilowatt-hours year-on-year, an increase of 5.6%; actively carry out new businesses such as user-side energy management and operation and maintenance, expand revenue sources, enhance user stickiness, and further increase the proportion of electricity in terminal consumption.
