Required power forecasting system

The present invention provides a predicted power required by the system, comprising: a power using the data collection unit (6), the production plan storage unit (8), the model generating unit (9), and short-term power required prediction unit (10). Use power data collection unit (6) collecting each machine (3) the use of electric power data, and stores the data using a power storage unit (7). Model generation unit (9) based on usage data stored in the power storage unit using the power data (7), and the production plan stored in the storage unit past production plan (8), for each machine (3) generated each provision of electric power in product categories computing model. Short-term prediction required power unit (10) computing model, and future production plan stored in the production plan storage unit (8) based on the model of power generating unit (9) generates, is calculated for each machine (3) in the future the power required.
