Geospatial and techno-economic analysis of wind and solar resources in India published in Renewable Energy
Applying the MapRE methods and tools, we identified abundant renewable resources in India — 850–3400 GW for onshore wind, 1300–5200 GW for utility-scale solar PV, 160–620 GW for CSP with 6 h-storage. However, these resources are concentrated in the western and southern regions. Deriving capital costs from India’s 2017–18 auction prices, we estimated the 5th and 95th percentiles of levelized costs of energy generation ranging from USD 47–52 per MWh for solar PV and USD 42–62 per MWh for wind. On a levelized basis, these costs are competitive with those of coal-based generation, the dominant fossil-fuel technology in India.
We found more than 80% of wind resources that coincide with agricultural lands where dual land use strategies could encourage wind development and avoid loss of agriculturally productive land. Approximately 90% of CSP resources and 80% of solar PV resources are in areas experiencing high water stress, which can severely restrict deployment unless water requirements are minimized. Finally, we found co-location potential of at least 110 GW of wind and 360 GW of solar PV, which together could meet 35% of electricity demand in 2030.
