The components of a typical hydro system are as follows:
· An intake, often incorporated into a weir to diverts of the flow from the water course;
· A penstock pipe to convey the water to the turbine;
· A powerhouse, in which the turbine and generator convert the water's energy into electricity;
· An outflow through which the water is released back to the river or stream;
· Underground cables or overhead lines to transmit the electricity to it's point of use. These must be short enough to minimize 'voltage drop
