The production cost of a product is reduced without reducing the production amount of a product of the electrolytic apparatus in a fixed period. There are provided a planning apparatus, a method of generating an operating plan, and a program, the planning apparatus including an electricity rate prediction unit that predicts a transition of a future electricity rate by using an electricity rate prediction model that predicts a transition of an electricity rate in a target period based on a value of a first factor available before the target period, and an operating plan generation unit that generates an operating plan of an electrolytic apparatus in a first period in a future based on a predicted transition of the future electricity rate.
