This research details the design analysis process of a 100 kW Pump as Turbine (PAT) micro hydro system for Sangama Community in the Asari-Toru Local Government of Rivers State, Nigeria. In order to achieve this, governing equations of fluid flow in pumps and pipes were applied to determine suitable design parameters of the system components, and also to select appropriate pump configuration. A design software, PAT+, was built in C# to help perform the design computations involved, although the software can be applied to PAT design for any expected power rating and desired system efficiency. From the results obtained, t was seen that a single stage pump of 28644 rpm operating at a head of 19.23 metres was suitable to generate the expected power. Parameters were varied and plots generated to show the effect of some parameters on the other, and it was deduced that the system head is inversely proportional to the flow rate. Also, for higher power outputs, higher design heads would be needed, although expected design output of a PAT should not exceed 100kW.
