Off-grid fully renewable energy with free capacity shortage for remote electrification

This paper presents feasibility study on optimal sizing and economic assessment of community electrification in the remote area using fully renewable energy system. The electricity is proposed to be delivered from a centralized renewable energy generating station. Study is focused to obtain the most appropriate power generation configuration with the lowest energy cost along with free system´s capacity shortage over the study period. Possible renewable energy technologies analyzed in this study consists of micro hydro, photovoltaic-battery and wind turbine. From the analyses, system configuration that consists of all renewable resources is the most preferred one with least net present cost as well as least cost of energy during the project period.
