①Xiong'an Jucun’s “1+5+X” urban smart energy symbiote provides basic power security services for 170,000 people in whole Rongdong Area of 1,270 hectares. ②As China’s first smart energy symbiote combined with transformer substation, the “1” means the core function of electrical energy—ONE 220kV indoor above-ground transformer substation; the “5” include edge computing center—ONE computing cabinet、intelligent charging and discharging station—ONE charging box、integrated energy supply—ONE energy storage box、green energy fitness experience hall—ONE swimming pool、emergency support and evacuation center—ONE shelter house; “X” represents for the featured innovation of 5G, ecosystem and waste heat utilization. ③Breaking the design and construction mode of traditional independent substations, Jucun’s smart energy symbiont adopts the innovative construction idea of integrating into the public park. The park slopes gently from the north, west and south sides of the substation roof. The roof garden at the top of the substation is thus integrated with the overall landscape, making the substation hidden. Meanwhile, the "5+X" extension function is laid out in the space formed by the slope. The space of the whole plot can thus be three-dimensionally developed. ④As the first station of Xiongan Power grid, Jucun’s smart energy symbiote also undertakes the important task of absorbing and transmitting renewable energy from National Zhangbei Green Power Base in the New Area. Under the background of the "30/60" strategy proposed by the state, the exploration of this complex makes full use of the advantages of urban power supply facilities. An energy complex, with comprehensive utilization of a variety of energy, is built with electricity as the main body. Meanwhile, it can also help contribute to the realization of the "dual carbon reduction target". All these are of great strategic significance.
