Gansu Economic Daily Lanzhou News (New Gansu Gansu Economic Daily reporter Su Haiqin) On June 6, the reporter learned from the Provincial Department of Transportation that the maintenance and renovation project of the first near-zero carbon service area renovation project in Gansu Province - G22 Qinglan Expressway Jiazui (Yuzhong County, Lanzhou City) service area has been successfully connected to the grid to generate electricity, marking the official completion of Gansu's first near-zero carbon service area.
This project is implemented by Gansu Expressway Service Group Co., Ltd., adhering to the concept of "energy-saving, clean, circular, and intelligent", and integrates and applies new energy equipment such as photovoltaics, breeze power generation, energy storage, and high-power liquid-cooled super fast charging. The project makes full use of the idle land resources in the Jiaojiu service area (including car parking spaces, highway slopes, and idle sites), builds slope photovoltaics, photovoltaic sheds, photovoltaic corridors and photo-storage and charging super charging stations, and is equipped with breeze power generation systems and energy storage equipment. Simultaneously implement water-saving transformation and greening improvement, and systematically build a near-zero carbon model integrating "wind, light, storage, recharge, green, intelligence and water". Through the "spontaneous self-use and residual electricity grid access" consumption model, an integrated green energy system of "source, network, load and storage" has been formed, and a comprehensive energy recharge pattern of "oil, gas, electricity, and photovoltaic" in the service area has been fully built.
The total installed capacity of the project is 1.348 MW. After completion, it will significantly improve the charging efficiency of electric vehicles, water resource utilization rate and ecological carbon sequestration capacity, reduce traditional energy dependence, reduce energy consumption level, and promote the operation of service areas to approach zero carbon emissions. Trial operation data show that the average daily power generation in the service area is about 7,000 kilowatt-hours, and the annual power generation is expected to exceed 2 million kilowatt-hours, reducing carbon dioxide emissions by about 1,040 tons per year, achieving the expected target. In addition, the pick-up service area can provide charging services for 56 electric vehicles at the same time, and its charging service capabilities and efficiency rank among the top in the country's expressway service areas.
