Willy; Basically you have around 1470 KW of gross energy and with a good Turbine and generator from about 1100 to 1000 KW of energy.
900 KW with 9 M/s. The river of this size will have fish in quantity so the system may require the way to allow fish passage, up and down river. The Dam needs to supply half of the volume for proper ecological protections, so the lake will need supply 4 m/s for about 6 months a year. So the lake size would be 4 * 3600s/hr*24 Hr * 180 day = 62.208 ^6 cubic meters minimum and considerations for 2 season capacity maybe necessary. With a 8 meter depth average the area of the lake would be 7.776 ^6 meter^2 and in Kilometers 7.776 ^6 / 10 ^4 = 77.76 square kilometers or 8.8 Km per side if square. That is if the proper regulations are followed. First you need to define the site for pipe placement and the intake area - Penstock ( major enterprise). It is clear that it is best for you and your group to pay for the site survey and for the design of the hydro electric overall system. You are asking here for the assistance of such major project indicating that you do not have enough experience in this area, as well as, trying to get experts in this group to give free advice for such major project. With 15 meter head you may need 1 meter pipe size or a bit better., or possibly to have 3 smaller pipes, one for each turbine. 15 meter for a Francis. This project will cost several million dollars 2 to 4 million, I think. Plus the cost of power transmission and house electrification costs.

The river I am interested in has a fall of at least 15 meters and a flow of 10 cubic meters per second during the dry season. We intend to build a small dam to retain enough water to run our plant with a constant flow of 9 cubic meter per second. I need your help: - to evaluate the power potential in KW at the site - to select the appropriate turbines and generators - to select the cheapest but most relyable Penstocks ( diameter, type of material wether pvc or steel pipe) - to calculate the Head lost in the penstock ( depending on the type of material used for the penstocks) - and to calculate the effective electrical power that will be produced. I am thinking of installing 3 turbines, 2 will be operating and one will be on stand by. Is this reasonnable? The site is at a very remote location far away from any major town. The power will be used to run a small industry in the rural area and to provide light for the inhabitants of the nearby villages. Thanks Willy L.
