In the Beijing Road Business District of Guangzhou, Guangzhou time-honored brand experience center, which gathers more than ten intangible cultural heritage brands, has attracted an endless stream of tourists since its trial operation in October this year. It took 3 years from design to opening, and Yu Guidong, the operation manager, really felt the continuous optimization of the electricity business environment in Guangzhou. "In the past, it used to cost hundreds of thousands of yuan to invest in transformer power supply. Now, thanks to the first trial of Guangzhou Power Supply Bureau in China, small and micro enterprises with reported installed capacity of no more than 200 kilowatts can use low-voltage power supply, realizing zero investment in power connection." Yu Guidong sighed that he not only saved a large amount of costs, but also applied for power on the mobile phone. "Zero to zero approval" means that power can be connected in six days. The report of the Twentieth National Congress of the Communist Party of China proposed to improve the basic systems of market economy such as property rights protection, market access, fair competition and social credit, and optimize the business environment. "Access to electricity" is one of the important indicators to measure the regional business environment. Guangdong provides power supply services of "simple, fast, and good province" for market players. From 2020 to 2021, in the evaluation of "obtaining power" in China's business environment, Shenzhen and Guangzhou will keep ahead of the rest of the world, and Dongguan and Foshan will enter the benchmark demonstration ranks. The fifth factory of GAC Toyota Motor Co., Ltd. was officially put into use recently when the user handled the electricity business "not once". Previously, GAC Toyota logged into the online joint service platform of Guangzhou "Electric Water and Gas Heating Network", filled in "one form" and clicked "one click confirmation", and then enjoyed the "one-time operation" of five major businesses of the electric water and gas heating network. It took only 20 working days to transmit power successfully, saving 60% of the average time from loading to power transmission. In view of the problems of "back and forth", "multiple processes" and "long time consuming" in the past, Guangdong Guangzhou Power Supply Bureau of China Southern Power Grid took the lead in introducing the "four offices" (initiative, online, joint, and one-time) in the country, to achieve the goal of "not running once" for users to handle electricity business, and reduce the processing time by telegraph by 80%. With this as the improvement sample, China Southern Power Grid copied the experience of "four offices" of Guangzhou Power Supply Bureau, and created a "one region, one feature" electricity business environment according to local conditions, so that users can save time, worry and money. Since this year, China Southern Power Grid has carried out online management and advanced agency services for 2209 major projects, and completed power access for 635 major projects of key enterprises in the industry chain, such as semiconductor, new energy vehicles, rail transit, panel manufacturing, new energy batteries and materials. In order to significantly reduce the power supply process, China Southern Power Grid cancelled the design review and intermediate inspection links of telegraph installation, and optimized the low-voltage and high-voltage installation reporting into two and three links respectively. Through online acquisition and verification of business license, ID card and other information loaded by telegram, the "face to face electricity" and "one certificate to do electricity" of residential users and enterprise users have been realized. 29 cities in the power supply area have achieved joint electricity, water and gas services. At the same time, China Southern Power Grid has realized "zero investment" for small and micro enterprises with a capacity of 160 kilowatts and below. In the past three years, the accumulated extended investment has reached 33.32 billion yuan, reducing customer investment by more than 60 billion yuan. During the "Fourteenth Five Year Plan" period, China Southern Power Grid is expected to invest 323.2 billion yuan in distribution network to solve problems such as distribution network congestion and low voltage, and continue to improve power supply quality.
