GRAVITATION WATER VORTEX POWER PLANTS

ECONOMY

Basically GWVPP differ from conventional hydro power plants because of low efforts in installation and service:

• GWVPP needs no expensive regulation systems.
• GWVPP needs no fine screen to protect the turbine.
• GWVPP needs no additional fish pass.
• GWVPP needs no power transformer for connecting to the power grid.
• The operating expenses are low - only checking the integrity of the coarse screen.
• GWVPP uses a minimum of moving parts and need only low annual service.

As an example for a short amortization period of GWVPPs, we can offer you the data of our own 10kW-GWVPP, which is in operation since 2006:

• The investment for construction of the 10kW-GWVPP in 2006 was 60.000€.
• The costs of maintenance and operation (service, insurance, ...) amount around 1000€ per annum.
• The average output was 55.000kW per annum or (at an emolument of 0,2€/kWh for energy consumption of the own company building) 11.000€ per annum.
• Depending on the modell of investment for construction a 10-KW-GWVPP can amortise during 7 years. After 7 years of operation total expenses of 67.000€ are accompanied incomes of 70.000€.

Important for a short period of  amortisation is that you can use the energy output of your future GWVPP at yourself (your privat house, your company, ...)!

Compared to photovoltaic systems GWVPP generates green energy all of the time. So the investment for a storage system can be reduced dramatically. 

GWVPP are suitable for local green energy systems at small rivers. The amortisation of GWVPP can be calculated by the reduced costs for external energy. GWVPP are in use like a conventional hydro power plant for 50 years and more. So during 35 years the owner and operator of a GWVPP earns two times more than the basic investment and they are still owner and operator of a hydro power plant, which generates green energy.

As an investment for an infrastructure programme GWVPPs offer the benefit, that GWVPPs are rather small projects and so the return on investment (ROI) starts after a short time of installation.

Also larger GWVPPs can be completed in a half year, when really large hydropower projects extend into several years, whereat costs could be increased dramatically.

Scaling in several small projects, the investment risk is significantly lower than to invest in a large-scale project. If you stopped your investment after one or two or three GWVPPs, you have several realised projects. Otherwise you have a great building yard and your money is lost.
