41 energetica INDIA- May_2020 SOLAR POWER Figure 5. Power consumption of units (BU) An addition of these energy demand figures in BU gives the energy demand in MSMEs, which estimates to 186.81 BU. The following formula has been used, wherein the data from the previous graphs has been incorporated: MSME industrial clusters X size of individual clusters X energy intensity of clusters based on the type of industry = overall de- mand of industrial MSMEs From this energy demand, the rooftop potential ofMSMEs can be estimated. The following factors havebeen considered to evaluate the demand of rooftop solarinstallation in MSMEs: • Overall energy demand from industrial MSMEs (from top- down and bottom-up approaches) • Likely percentage of consumers owning their roof: 60% (based on primary estimates by EY) • Likely percentage of consumption met from solar rooftop: 15% (based on primary estimates by EY) Following are the calculations that have been carried outbased on the aforementioned two approaches in Table 1below. The estimated rooftop solar potential from the top-downap - proach gives us a figure of 17.9 GW, whereas the bottom-up - approachbrings us toa figure of16.4 GW. So, it is observed that both the approaches converge torooftop solar potential figure of ~16.5 GW to ~18 GW in theMSME seg - ment. This is clearly a huge potential, which ifproperly tapped, can go a long way towards meeting half ofthe rooftop solar target of 40 GW by 2022.
