ENN adopts advanced information technology to realize the intelligent operation of a comprehensive energy infrastructure network combining "gas, electricity, heating and cooling”. Supported by energy reserves, ENN applies the integrated energy to achieve multi-energy complementation and supply-demand match, and provide customers with "clean, efficient, safe and superior" integrated energy services. Horizontally, ENN expanded from gas pipe network to gas, electricity, cooling, heating and other energy networks. Vertically, ENN extended its service to a full life cycle operation and management, including investment planning, engineering and construction, asset operation and maintenance, energy procurement, and transmission and distribution. In addition, based on core technologies such as mobile Internet, IoT, cloud computing, big data and artificial intelligence, ENN has built an intelligent management system platform to realize "safe, efficient and low-cost" operation of integrated energy infrastructure network.
