IX. APPENDICES APPENDIX A: PV SIZING To assess how much capacity is required to enable solarization of agri-feeders and grid-connected pumps, as well as the energy subsequently generated for use and sale, this report uses data on locationspecific agricultural loads and estimates of local solar generation potential to determine the average capacity utilization factor (CUF) of PV systems under local conditions and the yearly energy available for use/sale under both KUSUM A and KUSUM C. Results of this analysis are used to inform: 1) A financial analysis of costs and benefits to farmers and developers participating in KUSUM 2) An assessment of KUSUM’s financial impact on Discoms with irrigation pumping loads 3) Estimates of the currently specified KUSUM scheme’s technical potential to meet statewide irrigation electricity needs Data and Methodology Agricultural Loads Data on agricultural loads at substations across the state were taken from the Jaipur, Ajmer, and Jodhpur Discoms tender documents for KUSUM A. The comparable documents for KUSUM C provide the state’s estimates of the number of agricultural pumps of a given size that could be solarized within each Discom under the scheme. PV Systems Estimates of hourly solar generation and resulting capacity factors for fixed array solar installations during typical meteorological year across the state relied on calculations using the National Renewable Energy Laboratory’s PVWatts tool.161

•
Feeders: PVWatts assumes 14.8 percent losses due to soiling, shading, light-induced degradation, wiring, and age to account for local conditions of use. in addition, the analysis for solarized feeders assumes 10 percent losses from moving the electricity from panel to substation.162
•
Solar Pumps: Only PVWatts-derived 14.8 percent losses were included in these calculations, as proximity of the PV array to the pump under this scheme reduces distribution losses.
