ABSTRACT Industrial manufacturing units like cement and steel are benefited little by solar electricity. This paper presents feasibility of application of solar electricity in cement manufacturing plants in a distributed manner. Distributed solar PV systems without battery have been simulated using HOMER Pro micro grid design software to see the effects on net present cost (NPC), levelised cost of energy (COE), pollutant emissions, coal consumption and cost of cement production. The daily solar radiation ranges from 3.79 to 6.71 kWh/m2/day and the total distributed load supplied by solar electricity is 8876.4 kWh/day which is 0.82% of overall plant load. The results show that proposed system reduces pollutant emissions by almost 23% with an increase of NPC by 3.075% and COE by 0.6436% only. It saves 709,139 kg coal per year with 0.6437% increase in cement production cost. Proposed system will be beneficial economically too when PV prices come down in future.
