Lawrence: As Cesar say, the site is very nice. You can contact Fred Howe, from T.H.E.S., Kimberley, in your pretty country, for advice. There are many electronic THES electronic governors for MHP plants in Chile, most of it installed by us. This the reason why I know Fred, not personaly, only by mail.

Fly Boy <[EMAIL PROTECTED]> wrote: 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 Balisky 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. --------------------------------- Do you Yahoo!? vote.yahoo.com - Register online to vote today!
