Rapid technological advances require electrical energy for its operations and human needs fulfillment. Water energy is abundant in nature and could be used as an electrical energy source. The cross flow is most widely applied as micro-hydro power plants because it can operate at low head, a small water discharge, simple in construction, easy and inexpensive maintenance. But the cross flow performance is still low, since it is only uses one turbine nozzle, so that the turbine blade effectiveness in absorbing water energy is still low. This aim of this study is to test the cross flow turbine performance with a dual nozzle as electricity generation. The results showed that the Cross Flow turbine performance with dual nozzle produces a larger power output and higher efficiency even increase significantly the electric power output as big as 4,038 Watt, with a system efficiency of 52.72%. While the cross flow turbine with a single horizontal nozzle has a lower performance which is 3,468 Watt, with system efficiency of 45.97% and on a single vertical nozzle which is 2,925 Watt with a system efficiency of 38.78%. © 2006-2016 Asian Research Publishing Network (ARPN).
