Too little or too much – the everyday story of a hydro

I’ve had a lot of conversations with visitors this summer about the level of water needed in the stream to power up the hydro.

Most of the summer there’s barely a trickle in the steam, but give it a couple of nights of torrential downpours and it looks a bit like this. high water in the stream

Unfortunately from a hydro point of view, this is all going to waste.  The system is limited in terms of its capacity to 3kWh and when that is reached it can’t take any more water.  So it is a matter of boom and bust – either not enough pressure to spin the generator or so much that much of it can’t be used.

Oh, for a flexible system that would work at both ends of the spectrum!
