India’s renewable energy transition is entering a capital-intensive phase as the government focuses on mobilising investments, expanding infrastructure and strengthening domestic manufacturing capabilities. Over the next four years, the country will need to accelerate not only renewable power generation but also develop the supporting systems required to ensure reliable electricity supply at scale. Renewable Energy Secretary Santosh Kumar Sarangi said India would require approximately $220 billion in investments between 2027 and 2030 to achieve its target of 500 GW of non-fossil fuel-based energy capacity. The investment requirement extends beyond renewable power generation projects. It also covers the faster deployment of energy storage systems, expansion of electricity transmission networks and development of a stronger domestic manufacturing ecosystem.
India Requires Massive Investments to Accelerate Energy Transition
Sarangi’s estimate highlights the growing financial requirements as India moves from setting renewable energy targets towards large-scale project implementation. The country has already attracted nearly $64 billion in investments into the renewable energy sector since July 2024. This includes approximately $6.2 billion in foreign direct investment (FDI), he said while addressing the media ahead of the Bharat Renewable Energy Summit & Expo. However, the projected investment requirement of $220 billion between 2027 and 2030 indicates that existing capital inflows will cover only a portion of the funding needed for the next phase of expansion.
Energy Storage and Transmission Infrastructure Gain Importance
As renewable energy capacity increases, India must also strengthen its electricity grid to manage the intermittent nature of solar and wind power generation. Consequently, energy storage technologies, including battery energy storage systems, will play an increasingly important role in balancing electricity supply and demand. At the same time, expanding transmission corridors will help transport renewable electricity from generation centres to major consumption hubs. Furthermore, investments in grid infrastructure and storage solutions will be essential to improve power reliability and integrate larger volumes of renewable energy into the national electricity network.
Domestic Manufacturing to Support Renewable Energy Growth
Alongside infrastructure development, strengthening domestic manufacturing capabilities will remain a key priority. Expanding local production of renewable energy equipment, storage technologies and associated components can support project execution while reducing dependence on imported supplies. The next phase of India’s clean energy expansion will therefore create investment opportunities across several segments, including solar and wind power, energy storage, power transmission, grid modernisation and renewable energy equipment manufacturing.
2027–2030: A Critical Phase for India’s Renewable Energy Ambitions
The estimated $220 billion investment requirement underscores the scale of India’s clean energy ambitions. While the country has already attracted substantial capital into renewable energy, achieving the 500 GW non-fossil fuel capacity target will require significantly greater financial participation and coordinated infrastructure development. As reported by etsustainability.com, for investors and industry stakeholders, the opportunity will extend beyond solar parks and wind farms. Energy storage, transmission networks and domestic manufacturing will become equally important components of India’s renewable energy growth strategy.
