Abstract: For decentralized biomass plants using farm residue as input, the economic viability study are available in literature. The study calculates the different aspects of the cost of biomass power plants such as the cost of capital investment, running and maintenance of plants, residue processing costs, and the economic value equivalent of embedded nutrients (NPK) that are lost from residues. A comparison is drawn between the costs and revenue from the plant’s power generation. The word modest is used for giving analogy to the power plant which has capacity higher than decentralized power plants and lower than centralized power plants. In Gujarat there exists total four biomass power plants which should be considered in the modest category. The aim is to establish the cost efficiency of adding soil nutritious chemical fertilizers and using agricultural residues for the purposes of energy-building biomass (rather than incorporating soil). To study economic viability, the discounted rate method is used. In our paper, a modest / centralized biomass power plant has been studied for economic feasibility. For this, we have selected the state of Gujarat and followed district-wise analysis. We have used the penalty method given in optimization research in order to calculate transportation and other costs. Also, we studied a soil nutrition index for measuring soil health and the proportions of N, P and K in the soil. For annual crop production, the data used is district-wise for Gujarat state for the year 2011-12.
