(ENRIC2014) Economic feasibility The feasibility of the LRF system is ultimately governed by its ability to produce electricity at a low rate. In order to determine the economic feasibility of the system it is necessary to obtain a cost metric that can be compared to the current rate of electricity. In order to do this, all major lifecycle costs associated with the system is estimated. For the analysis, a useful plant lifetime of 20 years is assumed. The resulting levelized cost of electricity from the system in Abuja is $ 0.286 /kWh and in Bangkok is $ 0.289 /kWh. Economically the study suggests that, under the given operational, maintenance and ORC cost assumptions based on reference [15], the LFR solar electricity generates about NGN 46.26 /kWh in Abuja and ฿ (Thai baht) 9.20 /kWh in Bangkok. It should be noted that the collector price used in the economic analysis was based on the price used by the system advisor model (SAM) which have been stated to be a reliable simulation software tool for solar thermal and photovoltaic systems [18]. Conclusion In conclusion, the results of the simulation have shown that the performance of the LFR system in both regions is surprisingly close. The climatic conditions in Abuja enhanced the performance of the LFR system slightly above its performance in Bangkok during the summer periods. The storage temperature and temperature difference in the power block where influenced by the ambient and both systems showed similar performance during the wet or rainy season. Technically and economically the solar concentrating LFR have potentials for electricity power generation in these regions.
