Technical and Economic Analysis of Site Implementations of Gravitational Water Vortex Power Plant

This paper presents the analysis of twenty-seven gravitational water vortex power plant (GWVPP) installed in Asia, Europe, Australia, and South America based on technical and economic data provided by the organizations who were involved in those installations. Subsequently, the best technical solution for the optimal installation of GWVPP is proposed. In addition, cost components of those installations are compared and thus, economic site implementation plan that is suitable for installation in off grid community of Nepal is proposed. Moreover, the cost components are compared with that of existing micro hydropower system of Nepal, and it is found that the civil works account for most of the total investment cost. So, three kinds of sites, having irrigation canal, weir, and reservoir beforehand, are proposed as site implementation options so that civil works' cost are reduced. Theoretical designs for the civil works of GWVPP integrated into these water infrastructures are presented and construction costs are estimated. To verify, a system of 1.6kW designed in the previous studies is upgraded and reintegrated is used in the present irrigation canal. This paper concludes that GWVPP is suitable for rural electrification, specifically in low head sites in Nepal andfor the optimal site implementation the civil works cost should abate.
