Why small scale hydro? 

benefits

 

  • This power you generate can either get you off the grid completely or reduce your current cost of electricity with immediate effect.

  • Low maintenance and reliability - there are existing turbines that are still running after 30 years.

savings

 

  • The cost of the installation is also potentially fully tax deductible in year 1.

  • Once the installation is paid for the price of your electricity will not go up.

  • The cost saving benefit to anyone who has access to a source of running water with a fall of 700mm and as little as 150lt/sec will save you R38 000 per year.

syphon turbines

  • Mavel, a company in the Czech Republic is our supplier of this type of technology. They have 4 turbines in their range.

  • They work from heads as low as 1,5m to a maximum head of 5 meters and volumes from 0,15m3/s to 5 m3/s.

  • These turbines will produce power from 5kW to 160kW.

axial flow turbines

  • Our range of Pico Hydroelectric Turbines available from China start at 300 watts (this will run a small LED lighting system) using 20lt/sec and a head of 1-2 meters up to 5kW with a head of 3m and a flow of 250 lt/sec.

tubular turbines

  • Our range of tubular turbines will work from heads as low as 5m and a flow of 25lt/sec - producing 0.6kW whereas a head of 10m and a flow of 125 lt/sec will produce 10kW.

  • The larger the flow the higher the power - we are currently installing a 40kW unit in Gauteng.

gravitational water vortex power plants

  • This is fairly new technology and there are currently 29 installations worldwide.

  • We have teamed up with Rabin Dhakal, a leading academic in Nepal who has refined the design of the rotation tank and impeller to improve the efficiency of these devices.

  • This device works from heads of 700mm up to 2,5m. To date the largest installed unit is 50kW but they can be installed either in series of parallel dependant on the site and the volume of water available.

  • We will be involved with building one on the Hennops River - also in Gauteng. This will consist of two 150kW units with a head of 2m, and we have visited Zambia where there is the potential to install up to 300kW using this technology.
