Description
The study presents an analysis aimed at choosing between off-grid solar photovoltaic, biomass gasifier based power generation and conventional grid extension for remote village electrification. The model provides a relation between renewable energy systems and the economical distance limit (EDL) from the existing grid point, based on life cycle cost (LCC) analysis, where the LCC of energy for renewable energy systems and grid extension will match. The LCC of energy feed to the village is arrived at by considering grid availability and operating hours of the renewable energy systems. The EDL for the biomass gasifier system of 25kW capacities is 10.5km with 6h of daily operation and grid availability. However, the EDL for a similar 25kW capacity photovoltaic system is 35km for the same number of hours of operation and grid availability. The analysis shows that for villages having low load demand situated far …
