Ideal geographical conditions for building pumped hydro storage (PHS) plants include:
- Mountainous or Hilly Regions: Areas with significant elevation differences are ideal for PHS. This allows for the construction of two reservoirs at different heights, facilitating the flow of water through turbines to generate electricity.
- Proximity of Reservoirs: The distance between the two reservoirs should be minimal while maintaining a maximum vertical drop. This optimizes energy efficiency by minimizing the length of pipes (penstocks) needed.
- Abundant Water Supply: Regions with ample rainfall or a constant water source are preferable to ensure continuous replenishment of the reservoirs, reducing the need for external water inputs.
- Stable Geological Conditions: The presence of hard rock formations, such as granite or similar types, can provide a stable environment for constructing facilities like tunnels and caverns within the mountainside.
- Accessibility and Connection to Grid: The site should have good connectivity to the national power grid and be accessible for construction and maintenance purposes.
These conditions allow for efficient operation, minimize environmental impact, and ensure long-term durability of the facility.
