This on-line calculator is for general information only,
it does not include many issues, items, components, expenses, taxes, fees, insurance
and other elements and parameters which may influence the economic considerations.
In addition, the calculator applies Francis turbine efficiency curve formula which is specific for this calculator and cannot be used for other turbines.
Income tax related to electricity export may be entered to the calculator by decreasing the electricity export tariff to the net value.
Other taxes, fees, insurance and other expenses may be added to O&M cost.
One-time taxes, fees and expenses may be added to investment cost.
This calculator must NOT be used for actual design, or economic evaluation, or decisions regarding any real project
