Abstract:
This study is focused on a model towards choosing between offgrid biomass gasifier system and conventional grid extension for rural village electrification. The approach is to formulate a relation between biomass gasifier system capacity and the economical distance limit (EDL) from the existing grid point, based on life cycle cost analysis (LCC). EDL is the distance at which LCC of energy for both the options will match. The life cycle cost of energy is calculated for various capacity of biomass gasifier system at various operation hours and grid availability. The LCC of energy varies between $ 0.12/kWh to $ 0.11/kWh for gasifier system capacity of 10 kW to 120 kW for 6 hour of daily operation. The EDL for a 25 kW biomass gasifier system is 10.4 km considering 6 hours of daily grid availability and operation. This analysis shows that for villages having low load demand situated comparatively away from the existing grid line, the gasification based systems are cost competitive than photovoltaic systems or even grid extension. CO2 emissions mitigation benefit from the biomass based system is also included in the analysis.
