Fatal Flaw Assessment of 2 HPP Sites in Georgia

As part of the USAID-financed Development of Regional Energy Markets (D-REM) Project, IM Maggia Engineering and IM Engineering Eurasia will conduct a fatal flaw analysis of the technical feasibility of 2 proposed hydropower sites. Khada HPP and Aragvi 3 HPP have been identified for technical assistance.  

The primary objective of the study is to determine whether there are any fatal technical flaws to the two proposed sites, which in turn, will determine whether either or both sites should be the subject of a further, more detailed feasibility study.
