Reporters today learned from State Grid Shanghai Electric Power that under the organization of the East China Regulatory Bureau of the National Energy Administration, the Sixth China International Import Expo successfully purchased 8 million kilowatt-hours of green power through inter-provincial green power trading, which can cover the CIIE. The entire electricity consumption during the exhibition also marks the first time that the CIIE will implement an all-green electricity exhibition, which is expected to reduce carbon dioxide emissions by 3,360 tons. By then, wind power, photovoltaics and other new energy sources from Anhui will continue to light up every light at the CIIE, drive every ferry vehicle, and run every piece of equipment on display.

This year’s CIIE aims at “zero-carbon, zero-plastic hosting, green and smart travel”. In addition to conducting green electricity transactions to achieve an all-green electricity exhibition, it also conducts research on carbon emission data such as building operations and catering supply during the CIIE. Calculate and use the purchase of carbon quotas to neutralize greenhouse gas emissions from the exhibition. The exhibition hall adopts a trigeneration system, which uses the waste heat generated by grid-connected power generation for cooling in summer, heating in winter, and domestic hot water, realizing cascade utilization of energy. Only the roof of the National Convention and Exhibition Center has a total installed photovoltaic power generation capacity of 2.2 MW. Achieve 4.6% emission reduction for the exhibition hall.

In addition, this CIIE advocates green and smart travel and ensures that all buses use new energy vehicles. According to calculations by State Grid Shanghai Electric Power, during this CIIE, the charging capacity of the National Convention and Exhibition Center bus charging piles is expected to increase by 734.52% year-on-year, and the charging capacity of surrounding public charging piles is expected to increase by 691.41% compared to the same period in 2019.

State Grid makes full use of its technological advantages and takes multiple measures to continue to amplify the characteristics of green power grid. State Grid Shanghai Electric Power will simultaneously connect these green energies to the “energy brain” of the Panoramic Smart Power Guarantee System to achieve safe, stable and efficient operation of green energy. There are a total of 3,943 data collection sensors in various venues of the National Exhibition and Convention Center, which are the neural tentacles of the “energy brain”. Based on the smart IoT system architecture, they collect and analyze the energy consumption of the venues in real time, supporting the National Exhibition and Convention Center in formulating the lighting system. , air-conditioning systems, advertising equipment and other series of energy-saving measures to improve the venue’s low-carbon energy-saving management level.

According to Li Wensi, senior manager of the equipment engineering department of the National Exhibition and Convention Center (Shanghai) Co., Ltd., “The power company analyzed the load level of the West Hall during the past five years and found that the power load level of the West Hall remained between 700 kilowatts and 1,100 kilowatts. The load rate is between 20% and 35%. Compared with the event schedule in the West Hall, during non-activity periods, if the load threshold set by the system is exceeded, a real-time reminder of the load abnormality will be issued and notifications will be given to turn off unnecessary lights, thereby achieving The goal of energy conservation and carbon reduction.”

According to statistics, in 2022 alone, the venue will save 1.5 million kilowatt-hours of electricity and reduce carbon dioxide emissions by 630 tons. Among them, 530,000 kilowatt-hours of electricity will be saved during the CIIE.
