摘要： To allow creating an efficient battery operation plan while considering uncertainties of a farm work time or the like caused by weather fluctuation. A battery operation plan creation system 10 creates an operation plan for a plurality of batteries 5 charged at a nano-grid 1 including at least one of a power generation facility or an electricity storage facility. The battery operation plan creation system 10 inputs a work plan including a work demand for the battery 5 required for a work in a farmland 2 and demand area weather information indicating a weather of the farmland 2; and creates the operation plan for the plurality of batteries 5 in the farmland 2 based on the input work plan and demand area weather information.
