GRAVITATION WATER VORTEX POWER PLANTS

are suitable to power single or multiple family houses, companies and technical facilities.

enable to use of unused hydropower potentials at innumerable river gradient steps and in accordance with the European Water Framework Directive.

are upstream and downstream navigable for migrating fish.

need no large dams or embankment constructions.

provide an additional living space for river specific aquatic plants, microbes and fish

 

 

 

 

 

   

Technical data of our 10kW-Gravitation Water Vortex Power Plant at Obergrafendorf in Austria:

Head: 1,5m

Flow rate: 0,9m³/s

Efficiency of turbine: 80%

Electrical power: 8,3kW

Annual working capacity (depending on the local and yearly variable rain fall): around 55.000kWh

Construction costs (in 2005): 60.000€

Operation monitoring: Webcam

Maintenance effort: Annual oil change

 

   

Electric power of a hydro power plant is calculated by flow rate, head and total efficiency factor. Usually a hydro power plant is designed for 5000 equivalent full load hours each year. So the annual working capacity can be estimated by the electric power and the equivalent full load hours.

 

We will support you with consulting and planning and during project realisation. 

     

    

To confirm the diagram above with the annually outputs, we want to show you the official output (our green power purchaser is OeMAG) of our 10kW-GWVPP with 63.256kWh in a season with high precipitation from October 2012 to September 2013

 

 

 

 

 

 

 

 

 

 

 

    

   


and with 50.911kWh in a season with low precipitation from October 2014 to September 2015. The lower annually energy outputs in the diagram results from maintenance work at the mill stream on which our 10kW-GWVPP and 4 additional hydro power plants are in operation. 

Conclusion - a correct dimensioned and installed GWVPP accomplishes a good utilization with 5000 (or more) full load hours each year like a correct dimensioned and installed conventional hydro power plant.

 

 

 

 

 

 

 

 

 

 

 

 

Also the energy output with 63.581kWh from October 2015 to September 2016 is a good seasonal result.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Even with low rainfall in summer 2017 our 10kW-GWVPP generates a high green energy output with 62.385kWh from October 2016 to September 2017.
