Benefits of Advanced Pumped Storage Hydro Facilities
- Grid Reliability and Resilience: Advanced PSH systems can help balance supply and demand in the power grid by providing ancillary services such as voltage stability, frequency control, and spinning reserves, which are crucial for integrating variable renewable energy sources like wind and solar.
- Energy Storage: PSH acts as a “giant battery,” storing energy during periods of low demand (often using excess energy from wind and solar) and releasing it when needed, thereby enhancing grid resilience and reducing the need for fossil fuels.
- Operational Flexibility: Advanced PSH technologies, such as adjustable-speed units, offer greater operational flexibility compared to conventional systems. They can regulate their power output more effectively, providing better support during periods of high or low electricity demand.
- Cost Efficiency: By leveraging low-cost electricity during off-peak hours to pump water into the upper reservoir and generating electricity during peak demand times when prices are higher, PSH facilities can reduce operational costs and enhance profitability.
- Environmental Benefits: By facilitating the integration of renewable energy sources, PSH can help reduce greenhouse gas emissions associated with fossil fuel-based power generation, contributing to a cleaner energy mix.
- Reduced Curtailment and Congestion: Advanced PSH facilities help minimize the curtailment of renewable energy sources by absorbing excess energy when it is not needed, thus reducing transmission congestion in the grid.
Overall, advanced PSH facilities play a crucial role in creating a more sustainable, efficient, and resilient energy system.
