New Delhi: India will need to mobilise an estimated USD 220 billion in investments by 2030 to support its clean energy expansion, including renewable power generation, transmission infrastructure, manufacturing, energy storage and green hydrogen, Ministry of New and Renewable Energy (MNRE) Secretary Santosh Kumar Sarangi said on Wednesday.

The government is looking beyond traditional sources of financing, with private equity firms, pension funds, mutual funds and other institutional investors expected to play an important role in funding the country's energy transition.
Speaking ahead of the Bharat Renewable Energy Summit & Expo 2026, scheduled to be held at Bharat Mandapam in New Delhi from November 2 to 5, Sarangi said the event would focus on developing a roadmap to mobilise the required capital over the next four to four-and-a-half years.
"So, from the previous event till 2030, in different sectors, we require 220 billion dollars of investment. That includes deployment, manufacturing, transmission and green hydrogen. All of it together represents an estimated requirement of 220 billion dollars of investment. The idea is to identify a roadmap through which this resource could be mobilised over the next four to four-and-a-half years," Sarangi told reporters.
Solar energy is expected to account for the largest share of the projected investments, with an estimated USD 70 billion required by 2030.
Transmission infrastructure will need another USD 40–45 billion, highlighting the importance of expanding electricity networks to accommodate growing renewable generation capacity.
The government has outlined the following sector-wise investment requirements:
| Sector | Estimated investment | |
|---|---|---|
| Solar energy | USD 70 billion | |
| Transmission infrastructure | USD 40–45 billion | |
| Wind energy | USD 25–30 billion | |
| Green hydrogen | USD 20–25 billion | |
| Energy storage | USD 20 billion | |
| Renewable Energy Manufacturing | USD 15–20 billion | |
| Hydropower | USD 12–15 billion | |
| Bioenergy | USD 3–5 billion | |
The investment estimates underline that India's energy transition will require much more than adding solar and wind power plants. Significant capital will also be needed to strengthen transmission networks, develop storage systems and build domestic manufacturing capabilities.
According to the ministry, India's renewable energy sector has attracted nearly USD 64 billion in investments since the previous RE-Invest summit in 2024.
However, mobilising another USD 220 billion by 2030 represents a substantially larger financing challenge, particularly as the sector expands into capital-intensive areas such as green hydrogen, battery storage and transmission infrastructure.
The government's ability to attract long-term institutional capital will be crucial, given the substantial upfront investment requirements and extended repayment periods associated with clean energy projects.
Prime Minister Narendra Modi is expected to inaugurate the Bharat Renewable Energy Summit & Expo 2026.
The four-day event, organised around the theme Invest. Innovate. Inspire, is expected to bring together participants from more than 75 countries, over 400 exhibitors and more than 100 curated sessions.
The summit will also be held alongside the ninth session of the International Solar Alliance (ISA) Assembly and the fourth International Conference on Green Hydrogen.
The government intends to use the platform to engage global investors, technology providers, project developers and financial institutions in identifying investment opportunities across India's clean energy ecosystem.
India has set a target of achieving 500 GW of non-fossil fuel-based installed electricity capacity by 2030, making large-scale investment mobilisation central to its energy transition strategy.
While renewable energy generation has attracted considerable investor interest, financing transmission infrastructure, storage and emerging technologies remains equally important for integrating additional clean power into the electricity system.
The USD 220 billion requirement also raises questions about how much capital can be mobilised through private investment, how financing risks will be distributed and whether projects can offer returns attractive enough for long-term institutional investors.

The upcoming summit will therefore be an important opportunity for the government to move beyond investment commitments and establish a credible financing roadmap backed by bankable projects, clear regulatory frameworks and timely infrastructure development.
For India, the challenge is no longer limited to setting ambitious clean energy targets. It is ensuring that financing, transmission networks and supporting infrastructure expand fast enough to make those targets achievable.
