At present, the construction of the SG-eIoT (State grid-electric internet of things) is an important content and key link for the State Grid Corporation to promote the construction of “three-type and two-network” and is the most urgent and important task of the State Grid Corporation. This paper proposes a comprehensive and profound interpretation of the connotation and significance of the SG-eIoT，pointing out the status form the prospective of technology, business and industry and challenges in the construction of SG-eIoT at the current stage .Besides the internal and external needs of the SG-eIoT construction is analyzed from the network requirements，interaction needs， network requirements and so on. Finally this paper analyzes and summarizes the key support technologies to realize the construction of SG-eIoT and its impact on the future power system.
