Abstract
This paper investigates an economic analysis for a hypothetical existing hybrid energy system consisting of a wind farm and a pumped-storage hydro power plant (PSH). In the simulation, the electricity generated by the wind farm, predominantly at off-peak hours, is stored in the upper reservoir of the hydro power plant and used at peak load moments. The hybrid system is designed using Homer Grid software, and the economic analysis considers different scenarios applying hourly electricity spot prices in Brazil. The results indicates that, nowadays, PSH is not feasible in Brazil due to both the current electricity spot price policy and inadequate forms of ancillary services remuneration.
