Business feasibility analysis of solar power plants in eastsumba energy zone

The purpose of this study is to determine the business feasibility of the East Sumba energy security zone solar power project. Low of electrification ratio and energy security index and very large of potential of solar-based natural resource energy or solar power plants (SPP) in East Sumba make this study important.

Battery schemes, it is not recommended for private
