7. India’s Ambitious RE Targets
2022
2016
33%
13%
Wind and Solar – 91% of total RE Capacity

8. Renewable Energy Impact
Infirm
Unpredictable
Unscheduled generation
Grid instability – frequency and voltage variations
Transmission constraints - excess generation needs additional transmission capacity or else it needs to be curtailed resulting in waste of renewable power. Else thermal power plants need to be laid off to accommodate RE power.
Inefficiency of power system, because of backing down of thermal power plants
Possibility of the California Duck Curve phenomena
