I need advise on how to proceed or if there is enough benefit to warrant a
project. I have a mountain side property with a non-fish barring stream
running through it. The top to the bottom of the property allows for 95m of
head at 0.43 m3/s (average over year). If I involve the neighbor�s property
I could add an extra 50m of head by placing the power house on their
property. In regaurds to distance to the grid, I don�t know the line
voltage but I can describe the poles outside. The telephone poles along the
road have a single wire at the top that attach through a transformer to a
second wire at mid-height on the pole. It is this lower wire that the
houses are directly attached to.
I don�t know how to even begin to price such a project nor how to estimate
the value of returns from a project like this. I am situated one hour drive
out of Vancouver, British Columbia, Canada.
Average flow (m3/s)
Jan = 0.31
Feb = 0.26
Mar = 0.31
Apr = 0.36
May = 0.73
Jun = 0.89
Jul = 0.68
Aug = 0.31
Sep = 0.21
Oct = 0.26
Nov = 0.47
Dec = 0.36
Figures are based on catchment size and extrapolated from a nearby stream
that has published flow readings.
Any and all advice would be greatly appreciated.

Lawrence,
you have a very nice site specially if this is an abrupt fall sinse you did not
mention the slope of the stream.
with some simple estimates, at 95 meters head and at the average flow, you can put up
a 200 kWs micro hydro power plant and at the lowest of 0.21 cms, you have a firm plant
capacity of 97 kWs. These are just estimates using an efficiency of 50% to consider
losses. You can even generate more if you involve the property of your good neighbor.
The grid you are referring to must be what is called a singel wire earth return (swer)
electric line. you can ask the utility maintaining the line the voltage rating of that
system.
first thing, do you plan to sell the generated energy? or generate only for your own
consumption?
regards.
