This shows several Alternators, and the power production curve for each over the range of RPMs. From what I have learned here, my 100' of head plus my 20+ gallons of flow per minute should allow me to spin a alternator @2200 RPMs. My projected energy needs are 400 Amps per day, or 16.66 amps per hour, according to the chart I should be easily able to produce the needed power and more with the larger stock Delco alternators. And it looks like there will be room for more improvement.
