The Role of Pumped Storage Hydropower
This section describes a specific form of hydropower that acts as a giant battery for the electricity grid, improving its stability and helping store surplus from renewables.
Pumped storage hydropower (PSH) offers a unique solution to the challenges of integrating variable renewable energy sources like solar and wind into the electricity grid. PSH plants use electricity to pump water from a lower reservoir to an upper reservoir during periods of low demand or high renewable energy production. When demand is high, or renewable energy production is low, the water is released back down to the lower reservoir, generating electricity as it flows through turbines. In essence, PSH acts as a giant battery, storing energy when it's abundant and releasing it when it's needed. This helps to stabilize the grid, reduce curtailment of renewable energy, and improve the overall reliability of the electricity supply. PSH is a mature technology with a long history, and it has the potential to play a significant role in a clean energy future. However, the development of new PSH projects needs to be carefully planned to minimize environmental impacts and ensure community acceptance. Choosing suitable sites, minimizing land use, and mitigating impacts on aquatic ecosystems are all crucial considerations.
