(efi_prod_1)= # Coupling hydro-power to the grid | Note| |-----| | A hydro power module in the market model can also have been left out of the `EFI-PROD-1` and `EFI-PROD-2` files, either by mistake or because there is no hydropower plant at this module. Any production at these modules is subtracted from the area firm load. | | In case of a module being a pump, the power used for pumping is subtracted from the power injection at that busbar. | | In the case of a share equal to 0 for all defined busbars it is assumed an equal share.| | For each step, all busbar weights are accumulated and relative shares for each busbar are computed. If the same busbar is listed several times, its weights are accumulated.| Selected hydro-power modules are connected to the grid busbars in `EFI-PROD-1.DAT`. Only hydro-power modules connected to one (1!) busbars are specified her. If a hydro-power modules is connected to more than one busbar use `EFI-PROD-2.DAT`. Note that a busbar can be connected to several hydropower modules.
