Design of a technically and economically sustainable hydro power plant considering Georgian legislation and international state of the art in terms of hydro power design.The hydro power plant (HPP) development is located in the Svaneti region in the northwestern part of Georgia and the Greater Caucasus, on the Lakhami river. CES has been awarded for technical consultancy services, the preparation of the feasibility study, and design services. The Lakhami HPP project was conceived as a two-stage run-of-river power plant cascade of two power projects, Lakhami HPP 1 and Lakhami HPP 2. Both projects followed a hig- pressure scheme consisting mainly of the headworks with appurtenant structures, a penstock and the surface powerhouse with the hydro-mechanical and electrical equipment. Lakhami HPP 2 was planned to use the outflow of Lakhami HPP 1 plus the additional flow of Lakhami river.
