Pumped Storage Plants
Hydropower plant plus energy storage – The most efficient large-scale energy storage solution for grid stability and renewable integration.
Hydropower Plant Plus Energy Storage
Pumped storage plants are multi-functional power facilities with high potential to meet today’s energy challenges. Their technology is based on the only long-term, technically proven and cost-effective form of storing energy on a large scale, making it available at short notice.
Energy consumption is rapidly increasing worldwide. At the same time, it is becoming harder to keep energy production and consumption in balance at all times. Pumped storage facilities provide the critical solution for grid stability and renewable energy integration.

Advantages of Pumped Storage Plants
Flexible and Reliable
React to grid fluctuations in seconds, generate or absorb excess power instantly.
Green Battery
The only large-scale, economically viable storage technology with proven track record.
High Efficiency
Up to 82% round-trip efficiency — highly economical for daily cycling.
Renewable Integration
Provides backup during low wind or cloud cover, enabling higher renewable penetration.
Exceptional Lifetime
Designed for 80+ years, long-term energy security and outstanding ROI.
Water Management
Additional flood control and water resource benefits for local communities.
Hybrid and Symbiotic Concepts
Wind-Hydro Hybrid
Combine wind farms with pumped storage: upper basin integrated into turbine foundations. Shared infrastructure lowers costs and environmental footprint.
Seawater Pumped Storage
Use ocean as lower reservoir instead of fresh water. Perfect for island grids and coastal areas, featuring corrosion-resistant technology.
Water-Energy Symbiosis
Combine seawater pumped storage with desalination plants → fresh water and clean energy simultaneously in arid coastal regions.
