A feasibility project study of the Lower Nakatuta SHPP was executed in 1997. A first revision of the previous study has been carried out by ENCO in 2015 in order to ascertain the main conditions for the viability of the project.

The new full feasibility study brings substantial improvement in order to cope with the actual regulatory framework for SHPPs and to reduce the capital cost.

In particular: the plant shall be a run-of-river type, and shall divert a maximum discharge of 31 m3/s via an open flow canal. Three (or four) parallel penstocks shall convey the flow from the forebay at the end of the canal to three Francis turbines, equipped with synchronous generators; the produced energy shall be transformed to a higher voltage and brought to the national electric grid by means of a 33 kV transmission line.
