Pumped Storage Case Study in Uruguay: Simulation and Value

Abstract

An hypothetical 220 MW pumped storage power plant to be incorporated in Uruguayan grid was considered. System operation modelling and an operation along 20-year simulation in order to estimate whole system supply cost savings was made applying the SimSEE tool. As outstanding results total cost much lower than the estimated without the system and some of projects main specifications should change in order to make it economically feasible. In addition, to have a better visualization how this technology might operate, simulations where run for several random weeks, including one during 2020 pandemic period.
