Abstract
The increase in intermittent sources of electricity in national grids is increasing the need for energy storage solutions. Brazil’s energy grid has a hydrothermal conformation that the provision of power to meet the demand is easily met with its numerous hydropower generators if there is water available to turn their turbines. With the intent of storing water and energy with a small flooded area for a whole cascade of hydropower plants, this paper proposes the construction of a new seasonal pumped storage plant (SPHS), named São Tomé SPHS, at the head of the Antas river in the Rio Grande do Sul state. Results show that the proposed SPHS plant would increase the hydropower in the dams in cascade in around 260 MW. Apart from this, the SPHS plant could also be used to store energy generated from solar and wind sources and generate electricity during peak hours.
