On August 24th, the "Ultra Grade Zero Carbon Building" - the headquarters base of Special Electric Power was put into use in Qingdao, Shandong Province. The building is located in Laoshan District and achieves 100% self-sufficiency in green electricity through integrated photovoltaic curtain walls, tiered battery energy storage, and coordinated charging and discharging of new energy vehicles. It can reduce carbon emissions by about 2500 tons per year. The project focuses on the integration of the three networks of "charging network, microgrid, and energy storage network", and relies on a digital smart platform to achieve efficient regulation, saving approximately 30% of energy costs.
