India energy sector: USD 500bn opportunity in 2026

What was announced at India Energy Week 2026

India’s energy sector is being positioned as a large, multi-year investment destination, with government and industry estimates pointing to a sizable pipeline across hydrocarbons and clean energy. Speaking on Tuesday at India Energy Week 2026, Prime Minister Narendra Modi said India’s energy sector offers investment opportunities worth USD 500 billion. In parallel, global consultancy Wood Mackenzie said India must mobilise around USD 145 billion annually in energy investments to sustain economic growth of about 6 percent through 2035 while also meeting long-term climate commitments.

The message from both the government and the consultancy was that India’s growth trajectory and its energy transition will require large-scale capital deployment, especially in the power system. Wood Mackenzie also estimated that India will require USD 1,500 billion in energy transition investment between 2026 and 2035. A significant share of that spending is expected to be directed towards transmission and distribution, grid modernisation, energy storage, and scaling renewables.

PM Modi’s investment pitch and priorities

Modi called on global investors to participate in India’s expanding energy landscape, framing it as central to national priorities and energy independence. He reiterated that India aims to attract USD 100 billion in oil and gas investments by 2030. He also said exploration is being expanded to one million square kilometres.

The Prime Minister noted that more than 170 blocks have already been awarded, and highlighted the Andaman and Nicobar basin as an emerging hydrocarbon frontier. The government’s approach, as laid out in the address, combines upstream expansion with downstream capacity building and broader gas infrastructure scaling, aligned with rising domestic and global energy demand.

Refining capacity expansion and the “refining hub” goal

India’s current refining capacity is around 260 million metric tonnes per annum (MMTPA), which Modi described as a major strength. The plan underway is to lift capacity beyond 300 MMTPA. In remarks linked to the same theme, Modi said India will soon become the world’s largest refining hub.

From a market standpoint, these numbers matter because refining capacity affects product availability, trade flows, and India’s role in global petroleum product markets. The statements at India Energy Week 2026 positioned refining as a strategic lever, alongside exploration and investment attraction, to support demand growth and energy security.

Wood Mackenzie’s USD 145bn annual investment requirement

Wood Mackenzie said India needs to mobilise average annual energy investments of about USD 145 billion to bridge the gap between robust economic expansion and net-zero ambitions. Joshua Ngu, Vice Chairman, Asia Pacific at Wood Mackenzie, said this capital must be strategically concentrated in power generation, storage, and urgent modernisation of grid infrastructure.

The consultancy’s framing is that sustaining around 6 percent GDP growth through 2035, while advancing the energy transition, requires consistent annual investment rather than episodic spending. It also underscores that investment needs extend beyond generation capacity and into the enabling infrastructure that keeps supply reliable.

Why the grid is a central theme

Wood Mackenzie’s estimate of USD 1,500 billion in energy transition investment between 2026 and 2035 places notable weight on networks and flexibility. The consultancy said a significant portion will be directed towards transmission and distribution infrastructure, grid modernisation, energy storage, and scaling renewables.

Rashika Gupta, Vice President, Power and Renewables Research at Wood Mackenzie, summarised the focus by saying the USD 1,500 billion investment “is not just about adding megawatts; it is about the wires.” In practice, the emphasis on “wires” points to the need for stronger interconnections, upgraded distribution, and systems capable of integrating variable renewable power.

Demand outlook: what the IEA expects through 2035

The International Energy Agency (IEA) expects India to be the largest driver of energy demand growth through 2035. The IEA also expects India to add about 2 million barrels per day (mb/d) to global oil demand during this period.

On gas, the IEA expects LNG consumption to more than double, citing urbanisation, industrial growth, and cleaner fuel policies. The same outlook notes that India’s oil demand is predicted to increase steadily through 2030. These expectations help explain why India is simultaneously pushing hydrocarbons investments and energy transition capital.

Key figures at a glance

Market impact: where spending is expected to concentrate

The article’s numbers point to two parallel capex tracks: hydrocarbons capacity and energy transition infrastructure. On one side, the USD 100 billion oil and gas investment target, new exploration area, and additional refining capacity suggest continued expansion of the conventional energy value chain. On the other, Wood Mackenzie’s USD 145 billion annual requirement and USD 1,500 billion transition estimate imply that a large share of capital must move into grid readiness, storage, and renewables integration.

For investors and policymakers, this split is important because it affects project pipelines across upstream, midstream, refining, power transmission and distribution, storage, and renewable generation. It also highlights that the reliability of the grid and distribution networks is being treated as a prerequisite for scaling clean power.

Analysis: why the numbers matter for execution

The stated investment needs are large, but the structure of the spending is equally significant. Wood Mackenzie’s repeated emphasis on transmission, distribution, and grid modernisation signals that the energy transition is being framed as an infrastructure challenge, not only a generation build-out. The consultancy’s focus on energy storage reinforces the idea that flexibility will be necessary alongside renewables additions.

At the same time, the government’s push for exploration expansion, block awards, and refinery capacity increases reflects expectations of sustained fuel demand, consistent with the IEA’s outlook for oil demand growth through 2030 and broader energy demand growth through 2035. Taken together, the remarks position India’s energy strategy as a mix of security, capacity expansion, and transition-enabling investment.

Conclusion

At India Energy Week 2026, PM Modi pegged India’s energy opportunity at USD 500 billion and urged global investors to participate, while Wood Mackenzie quantified the need for about USD 145 billion in annual energy investment and USD 1,500 billion in transition spending from 2026 to 2035. The common thread across both sets of remarks is that infrastructure, particularly grid modernisation and storage, will be central alongside oil and gas investments and refining expansion. Future updates are likely to focus on how investment targets translate into project announcements, grid spending plans, and further upstream and refining capacity decisions.
