Energy Internet is a developing trend of electrical power energy industry. The core message is to implement the next-generation of cyber-physical systems shaping future energy industry that is based on a deep merge of operational technology and internet information technology. The growth of energy internet is dependent on the availability of high performance computing and analytics technology to process a massive amount of data set. The paper discusses two core techniques that would support the growth of energy internet, big data and clouding computing, with a focus on the platform architecture that is particularly adaptive to handle a variety of characteristics of energy industry data. Finally, the paper summarizes and proposes a comprehensive, technical solution for energy big data and IoT cloud computing platform with applications focusing on energy consumption monitoring and complementary operation of multi-form energy system that support all aspects within a data lifetime cycle, e.g., acquisition, storage, analytics, and visualization.
