### Additional inputs needed for multi-stage modeling

#### Input data files
Instead of one set of input files, there is one directory of input files that needs to be provided for each planning period or stage (e.g., “Inputs/Inputs_p1/” for the first period “Inputs/Inputs_p2/” for the second period, etc.). Below we list the additional parameters that must be provided in the corresponding stage-specific input files to instantiate a multi-stage planning problem.
