SIMAHPP 4 Professional is a multi-site, multi-option simulator intended to solve a wide range of problems such as to determine design flows and to choose appropriate hydro turbine, optimize time of operation in a year so as to maximize annual energy production, determine the energy revenue, estimate investment and related costs, determine amortization rates, Net Present Value (NPV), Internal Rate of Return (IRR), payback periods, and indicates the quantity of carbon emission reduction potential if the planned hydropower project is to be operational. SIMAHPP 4 Professional offers much flexible simulation options and integrates a new module to conduct sensitivity analysis.

Outputs are detailed project characterisitics and result analysis (both tabular and graphical) basd on three key parameters: hydraulic, financial, and environmental parameters. The sensitivity analysis module helps to further customize project characterisitcs information to the desired range of key parameters and investment costs.

With SIMAHPP 4 professional, users have full control on all input parameters of various project scenarios and possibilities and can see results with a wide range of analysis and graphical demonstrations. The program has five major sections: advanced file manager, project options, hydraulic, financial, and environmental modules, and the Simulator.
