This study examines the decline in India’s wind energy generation during the peak monsoon season of 2020, outlines the micro and macro impacts of this anomaly and identifies potential solutions for climate-proofing the sector. It undertakes case studies to assess the extent of variability observed across farms in wind-rich states, identifies the underlying reasons, and examines the associated operational and financial implications for the stakeholders. It analyses the annual average wind speeds across 40 years for three states, Gujarat, Rajasthan and Tamil Nadu. It also assesses the daily average wind speeds between June and September for two districts - Jamnagar, Gujarat and Tirunelveli, Tamil Nadu. Further, it discusses the strategies to improve the wind resource predictability in India, and other interventions to ensure the sector’s preparedness to deal with emerging climate-induced risks.
With India’s ambitious targets of reaching 60 GW of wind power capacity by 2022 and estimates of 140 GW by 2030, wind power is and will continue to be an important constituent of India's electricity mix and decarbonisation journey. It is thus necessary to anticipate any potential risks to the accelerated development of the sector. Given that effects of climate change are becoming rampant all across the globe, it is likely that the future sees an increased frequency and intensity of anomalies in wind speeds and patterns. More robust and long-term climatological analyses are required to increase preparedness.
To climate-proof the wind energy sector, governments, public sector organisations, and the wind industry must invest in deep climatological research and modelling, adopt advanced weather and generation forecasting techniques, and enable cost-effective ancillary support services.
