AN ECONOMIC-FEASIBILITY ANALYSIS OF PHOTOVOLTAICS POWER DURING URBAN LOAD SHEDDING TIME

A first-order cost analysis of Photovoltaics power generation and DG p ower generation for urban emergency load is presented. Six years field data of two DG sets installed at IIT, Delhi for emergency load have b een thoroughly analysed to find out the requirements for such power ge neration model. The unit cost of emergency load energy is calculated u sing different parameters. These are the interest rate of commercial l oan at present value of Indian market, IREDA loan facility to promote PV, the depreciation cost, operation and maintenance cost of PV and DG sets, and fuel cost of DG set. It is found that the unit cost of PV e lectricity is cheaper or comparable with that from DG power at present market price. (C) 1998 Elsevier Science B.V. All rights reserved.
