The development of hybrid FPV/hydro power plants, is a cost-efficient measure to reduce the power intermittency and lack of ancillary services from PV power plants.. The asynchronous relation between solar irradiation and precipitation ensures resource availability on a yearly, seasonal and daily scale, and covering the hydro dam with floating PV (FPV) can reduce land use, and reduce reservoir water evaporation compared to onshore PV systems. A linear technoeconomic optimization model is formulated calculating the optimal FPV capacity for a given hydro power plant, to maximize the annual profits of this corresponding hybrid. The model is solved for 126MW hydro power plant situated in West Africa, selling power in a three tariff market scheme, i.e., firm peak, offpeak and intermittent power. The optimal FPV capacity is found to be 193MWp, increasing annual profits and decreasing profit variability between wet and dry years, compared to the stand-alone hydro power plant equivalent.
