Electricity grid constraints found to be the limiting factor in India’s renewables boom

New research from the International Energy Agency (IEA) estimates renewable electricity generation has saved India more than $100bn in fossil fuel imports since 2011, while identifying the grid investment and storage capacity needed to support further growth.
India’s installed renewable power capacity has almost quadrupled over the past decade, cementing the country’s position as the world’s second-fastest-growing renewable energy market and second-largest solar panel manufacturer, according to the new IEA report.
The analysis reveals the country’s capacity now exceeds 300GW, helping cut its dependence on imported fossil fuels while strengthening its role in global energy markets.
The report forecasts India’s capacity will grow to around 530GW by 2030. Sustaining this expansion, however, will require greater investment in electricity networks, energy storage and system flexibility, it notes.
The switch to renewable generation has saved the country more than $100bn in coal and natural gas imports between 2011 and 2025, with total savings expected to more than double by 2030. The report estimates that without the solar, wind and bioenergy capacity installed since 2010, India would have imported around 110mn t more coal in 2025 alone.
Commenting on the latest findings, IEA Executive Director Fatih Birol said: ‘India’s renewables expansion is delivering major benefits for its energy security at a time of heightened uncertainty in global energy markets.’
Looking ahead, the IEA forecasts solar PV will account for more than 80% of additional capacity in India by 2030. The report identifies competitive auctions as a major driver of growth, helping India achieve some of the world’s lowest solar electricity generation costs.
The country’s expanding solar panel manufacturing industry is also helping diversify global supply chains, giving consumers at home and overseas more choice over where they buy.
Recent renewables investment includes two solar projects commissioned by Engie – the 250MW Khaba plant in Rajasthan and the 200MW Khavda facility in Gujarat. The plants are expected to generate a total of around 1,000GWh of electricity annually.
Engie has also secured contracts for battery storage and hybrid solar-storage projects in the country, including a 280MW battery system and a development combining 200MW of solar generation with 100MW of battery capacity.
Aside from large wind and solar farms, two other sources of demand are contributing to India’s growth: households and businesses installing rooftop solar panels, and companies buying renewable electricity directly from generators.
The IEA has struck a note of caution, however, warning that India’s grid investment must accelerate to keep pace with renewable development. It also says the financial health of electricity utilities and delays in completing projects could slow growth.
If India can overcome these challenges, however, it could increase renewable capacity deployment by more than 20% between 2026 and 2030, according to the report.
