Today, the world is very much concerned about the global warming effects due to the increasing pollutant emissions from various sectors of manufacturing industries. They are majorly using coal based power plants for fulfilling their electricity need. The requirement is of switching some partial load on renewable system and finding alternative fuels that can help in reducing green house gases emissions. This paper presents the cost comparison of hybrid renewable energy systems comprising generators running by petroleum diesel, natural gas, fuel oil and biodiesel. Solar PV, wind, diesel generator and bettery bank are the components of the chosen hybrid system. Here, the effects on operating cost, Net Present Cost (NPC), Cost of energy (COE) and fuel cost has been studies. The optimized hybrid system has been modeled and simulated using Hybrid Optimization Model for Electric Renewables (HOMER) software developed by NREL, USA. The results show that system comprising generator running by bio diesel is most cost effective with respect to NPC and COE whereas system comprising natural gas generator has lowest operating cost. The fuel cost of systems comprising biodiesel and natural gas generators is found same and lowest.
