Storage Power. Storing renewable energies efficient.

Making green electricity easily accessible is one of the major challenges of the energy transition. Our Water Battery is the answer. The innovative combination of renewable energy sources and a pumped-storage power plant creates a powerful storage system for flexible power supply. The Water Battery acts as a short-term storage facility and helps maintain the grid stability.

The Components of the Water Battery

Water Battery concept mobile
Water Battery concept - storage basin, Max Bögl Wind AG

The newly-developed storage basin replaces the classic upper reservoir of the pumped-storage hydropower plant. Because of its prefabricated modular design, the water basin concept minimizes the impact on the landscape.

Water Battery concept - penstock, Max Bögl Wind AG

A penstock made of polyethylene connects the upper reservoirs with the lower reservoir. A special pipeline laying technique allows fast, resource-efficient and economical construction.

Water Battery concept - power station, Max Bögl Wind AG

The modular power plant is completely standardized and available in various power classes (16/24/32 MW). Reversible high performance turbines are the centrepiece of the electronically controlled power plant.

Watter Battery concept - lower reservoir, Max Bögl Wind AG

Due to its natural design, the lower reservoir blends harmoniously with the landscape.
