Nearly four years after the inception of this monumental project, on Friday, February 8, 2008 Simon opened the turbine, and when the RPMs hit 150, instructed Joel to energize the first motor/generator--sending electricity back into the grid for Red Bank Hydros first (unofficial) kilowatt-hour of production. We even made the meter run backwards for 2 kwh; too bad it was not an old-style, mechanical meter--would have been a better visual! Stats: *64 acre lake *40 cf/s average water flow, 10 ft. head *50 hp Francis turbine (refurbished 1960's era) *150 RPM (1750 ft/lbs calculated torque) *600 RPM at secondary shaft *1760 RPM motor/generators *each induction motor/generator: 15 hp, single phase, 230 VAC *peak power for test run: 40 amps (9600 VA) *eventual peak power generation: 24 kilowatts (sorry for the imperial units ;-) Kids, don't try this at home! It is dangerous to run this kind of equipment without proper mechanical guards and electrical safety circuits.
