【 摘 要 】

East Nusa Tenggara (NTT) is a province with low electrification ratio (78.3%) and high number of underdeveloped villages (74.8%), despite its abundant renewable energy resources potential. The objective of this study is to obtain technically-economically feasible village model with integrated renewable energy system for developing productive zone, Prukades-postharvest cocoa processing, in Wewaria, NTT. The methodology used is techno-economic analysis, in which technical analysis include optimization for hybrid power generation system (HPGS), done by using HOMER Pro. Several financing schemes are proposed to evaluate the economic feasibility. Environmental comparative analysis of mitigated GHG emission is also evaluated. It is found that the HPGS consists of 95 kW photovoltaic, 78 kW wind turbine, and 200 kW diesel generator, equipped with battery storage, and the Prukades system has annual capacity of 250 tons of wet cocoa beans/year with 32.9% yield. Prukades system is economically feasible with all proposed schemes, and potential to increase annual income of cocoa farmers. On the other hand, HPGS is only economically feasible with FS-5 scheme with 100% grant as financial intervention. The economic attractiveness of both systems is relatively higher by using integrated scenario, both owned by the same business entity, resulting in 3 other schemes to be feasible.
