This study conducted an analysis of economic feasibility with unit generating costs calculated based on scenarios of capacity factors, discount rates, government supporting rates, installation costs. However, It Is clear that few new and renewable energies can meet the tariffs [government purchasing prices] set by the government in light of the current market reality. Without the government support, solar PV is not economically feasible at the tariff of 716.40/kWh. in the case of wind Power, the current tariff of 107.66/kWh is not enough to make it competitive except for a mid- and large-scale wind farm The analysis showed that even small hydro is not economically acceptable at the current tariff of 73.69/kWh
