Renewable Energy Integration in India: Ways to Maximise Solar, Wind Power System
By Binit Das
The penetration of renewable energy in India is highly variable across states. The share of solar and wind in India’s 10 renewable-rich states — Tamil Nadu, Karnataka, Gujarat, Rajasthan, Andhra Pradesh, Maharashtra, Madhya Pradesh, Telangana, Punjab and Kerala — is significantly higher than the national average of 8.2 per cent.
Solar and wind account for around 29 per cent of annual electricity generation in Karnataka. It is 20 per cent in Rajasthan; 18 per cent in Tamil Nadu; and 14 per cent in Gujarat in financial year 2020-21.
India’s renewable energy-rich states already have a higher share of variable renewable energy (VRE) than most countries. As a result, many states are already facing system integration challenges.
The blog addresses the demand-side flexibility, power plant flexibility, storage (pumped-storage hydro and batteries) and grid flexibility, as well as policy, market and regulatory solutions for the short to medium term.
