The MORRO model was developed in Canada for use by the Ottawa River Regulation Planning Board (ORRPB) to integrate the operation of the Ottawa River during the spring freshet season, when the two objectives of flood damage reduction and energy generation must be considered. The model has been used since 1981 for the real-time operation of the Ottawa River System. This system is made up of 33 reservoirs and 43 hydraulic generating stations with a total installed capacity of about 3,500 MW. Since the model was developed as a generalized software package, it is also being used by Hydro-Quebec and Ontario Hydro for other river-systems. These two power utilities are using the model for river basin feasibility studies, assessing the impact of environmental constraints on energy production, after-the-fact performance evaluation of river system operation, and calculation of energy generation productivity. The paper provides an overview of the model and of its utilization in Central Canada.
