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® 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
