Plant_FinanceSE is a set of models for assessing overall wind plant cost of energy (coe). The models use wind turbine and plant cost and energy production information as well as several financial parameters in simple equations to estimate coe.

For detailed installation instructions of WISDEM modules see or to install Plant_FinanceSE by itself do:

$ python install

Run Unit Tests

To check if installation was successful try to import the package:

$ python
> import plant_financese.basic_finance.coe_fin
> import plant_financese.nrel_csm_fin.nrel_csm_fin

You may also run the unit tests which include functional and gradient tests. Analytic gradients are provided for variables only so warnings will appear for missing gradients on model input parameters; these can be ignored.

$ python src/test/
