Modeling and Feasibility Study on Pumped Hydro Storage System for Sri Lanka

Abstract

Due to Sri Lanka's reliance on imported fossil fuel for a large portion of its energy needs, the cost of energy has significantly increased. Sri Lanka has agreed to zero carbon emissions in energy generation by the year 2050, and the country’s future energy generation must depend on renewable energy sources. In the future, sustainable energy generation in Sri Lanka will be more favorable if water, wind, and solar energy are combined to generate energy. But since there are some limitations in the generation of that energy, measures should also be taken to store that energy for use within the required period. Pumped hydroelectric storage power plants are regarded as a reliable and effectively used energy storage technology. The thesis has mentioned the economic and environmental benefits of this pumped hydro storage system over existing non-renewable energy power plants by implementing this system using two existing reservoirs in Sri Lanka
