HYDROMATRIX® An innovative way to hydropower generation Conventional

HYDROMATRIX®

 An array („Matrix“) of small turbines instead of conventional sized turbines  Best suited for low head sites with existing dam and weir structures  Most economical in larger numbers -> not a typical „small hydro“ application 3

HYDROMATRIX® Application Range

Submergence > 1.5 m

Head 2 - 20 m HWL

TWL

Plant Flow > 60 m³/s Unit flow 5-12 m3/s Unit Output 100 kW up to 1500 kW

HYDROMATRIX® Advantages  Use of existing weir structures 

No major civil construction –> less cost



Little excavation & no coffer dams –> less geological risk



No additional land usage -> environmentally friendly



Existing river flow pattern can be maintained

 HYDROMATRIX® Modules removeable at flood conditions  Standardized modular concept
