Provided are an energy big data system and an operation management method associated with meter environment information. A method for managing meters according to an embodiment includes: collecting energy usage data from the meters; collecting environmental data of the meters; and predicting states of the meters, based on the collected environmental data. Accordingly, states of meters may be predicted based on collected environmental information and meter reading information of the meters, so that the meters may be efficiently operated and managed, and a new energy service may be provided through analysis of big data including meter reading information and meter installation environment information.
