A computer model for determining hourly releases and generation for multi-unit hydropower facilities is described. The purpose of the model is to disaggregate daily release volumes (either from historical records or from simulated data from other models) at the project into a plausible hourly schedule so that accurate peak and offpeak energy generation can be determined and evaluated. For each day of simulation, the user supplies the water release volume, reservoir headwater elevation, downstream reservoir headwater elevation (if tailwater is dependent on downstream operations), definition of peak hours, minimum flow requirements, and whether maximum capacity operation or best efficiency operation is to be achieved. The model is also capable of considering 'ramp' constraints. The model has been successfully used for various planning studies.
