The utilization of the Pumps working as Turbines (PATs) in micro hydro-energy resources to replace the convencional turbines as Pelton, Francis and Propeller have been used in countries as USA, Germany and France. In the mean time, in Brazil this practice and the utilization of induction generators working with PATs is still in the scope of the laboratory experiments. This work, based on experimental results carried on in Laboratory of Hydromechanics for Small Hydro Power Plants (Laboratório Hidromecânico para Pequenas Centrais Hidroelétricas - LHPCH - UNIFEI), (VIANA, 1987), (VIANA e NOGUEIRA, 1990), propose the utilization of assynchronous generator groups operating with PATs. To show the investment cost decrease in microhydro power plants (MHPs), is showed the Boa Esperança MPH exemple, in which is presented a comparison between the synchronous generator group cost working with a Michell-Banki turbine and a assynchrounous generator group operating with a PAT.
