The major issues associated with pumped storage hydropower plants lie in the scarcity of suitable sites for two reservoirs and a pumping station to be built with considerable elevation difference. This fundamental issue along with others gives rise to the series of problems that are discussed below.
In pumped storage hydropower, previously generated electricity is converted to potential energy when pumped uphill and stored in the form of water at an upper elevation (reservoir), where it later flows downhill to a lower reservoir through turbine and converted back to electricity.
Engineers can control the flow and generation of electricity almost exclusively, with the help of the pumped storage concept. The turbines can be programmed to pump water to the upper reservoir – consuming excess cheap energy and to generate electricity by letting the water lose potential energy.
Energy Loss: While efficient, pumped storage hydropower is not without energy loss. The process of pumping water uphill consumes more electricity than what is generated during the release, leading to a net energy loss. Water Evaporation: In areas with reservoirs, water evaporation can be a concern, especially in arid regions.
Pumped storage hydropower, while an effective means of energy storage and generation, has a significant impact on water flow and river ecosystems. The construction of dams and reservoirs for these systems can alter natural water courses, affecting both the physical and ecological characteristics of the area.
Challenges and Responses: Despite its benefits, pumped storage faces challenges like high capital costs and environmental concerns. Innovations and stringent environmental impact assessments are key to sustainable development.
