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
