Green power storage – modular and scalable for electric power of 0.5 MW to 15 MW

• with system efficiency of 70-80%
• quick response time 
• highly efficient and cost-effective
• considerable cost reduction thanks to needs-based assembly of standard components produced cost-effectively in series
• modular system of identical impeller or motor/generator units, in combination with commercially available frequency converters
• long lifetime, short construction time 
• for buffering of all forms of renewable energy
• excellent compatibility with other storage technologies

Level of innovation

• effective possibility for regional management at low and medium voltage level
• first fully modularised pump turbine for small or large series production
• most energy-efficient basis for hybrid storage solutions

Application & target groups

• use of existing water reservoirs and old mines
• increasing the flexibility of existing high-pressure hydropower plants by retrofitting
• new construction of pumped storage plants in alpine regions and in mining regions with little water and very high head
• operators and Installers of wind power or photovoltaic plants
• energy self-sufficient communities, showcase regions, regional and urban planning
• network operators
