Key points
- India's data centers could reach 3% of national power
- Long contracts make solar-plus-battery projects bankable
- Two forecasts disagree on how fast capacity grows
- The obvious US-listed play is leaving the market
India's data centers could account for roughly 3% of national electricity demand by 2030, up from less than 1% today. That growth is reshaping the power projects built around them.
Data centers need reliable electricity around the clock, not just cheap solar power in the middle of the day. The projects serving them need the same certainty: contracts long enough to support financing.
Nikkei Asia reported Monday that long-term agreements with data-center operators are making battery-backed solar and wind projects easier to finance. The forecasts differ on the size and timing of the buildout. They agree on the underlying shift: India is adding a large customer that needs power every hour of the day.
That's the bankability story. Solar produces when the sun shines. Add batteries, transmission access and a 20-year data-center contract, and a lender has revenue it can underwrite.
Two sets of numbers are circulating, and they don't line up.
| Measure | Outlook Business | Wood Mackenzie |
|---|---|---|
| Operational capacity, 2025 | About 1.2 GW | 2.2 GW |
| Capacity, 2030 | Almost 10 GW | 12 GW |
| AI-dedicated capacity, 2030 | Not broken out | 6,546 MW |
| Electricity use | 40-45 TWh by 2030 | 191 TWh by 2040 |
The 2030 capacity lines are close enough to ignore the gap. Ten gigawatts, twelve. Either way, it implies a sharp expansion by 2030. Where they split is the starting count and the finish line: Wood Mackenzie begins from a substantially higher base and runs its consumption number out to 2040, by which point it has data centers taking about 7% of India's electricity. Outlook Business, which carries the lower set, doesn't say whose forecast it is. Wood Mackenzie's is its own, published July 27.
The AI slice is what moves. "The convergence of hyperscale capital, AI workload growth and a decade of policy support have created the conditions for India to rival any market in Asia-Pacific," said Souhardya Pal, a research associate at the firm. Read the AI line in the table again: 275 MW in 2025, 6,546 MW in 2030. Most of that projected AI capacity has yet to be built.
Money is already committed. Google (GOOGL) has a roughly $15 billion India program and Microsoft (MSFT) has pledged $17.5 billion between 2026 and 2029. Reliance, Adani's AdaniConneX, CtrlS, Yotta and Sify (SIFY) are all building. India had 288.58 GW of installed renewable capacity as of June 30. Getting that power to the right place at the right hour is the harder problem, and that is transmission and storage rather than panels.
For a hyperscale data center, solar alone does not meet the need for round-the-clock power. "Land and capital are no longer the limiting factors for data centre developers in India," said Rashika Gupta, vice president of research at Wood Mackenzie, in the firm's July 27 report. "What determines site selection and delivery timelines now is access to firm, round-the-clock power at the node level." For these projects, batteries, transmission access and firm backup increasingly determine whether a long-term data-center contract is financeable.
The US-listed options are limited
The best-positioned companies, Adani Green, NTPC Green and Tata Power, are listed in Mumbai, not New York. The most obvious Nasdaq name is leaving too: ReNew Energy Global (RNW) agreed on August 11 to a take-private at $7.02 a share from a group including Canada Pension Plan Investment Board and founder Sumant Sinha, who already control about 70% of the stock. It closed Friday at $6.83. That's a merger spread, not a growth story.
Sify closed at $13.78 on Friday. It runs hyperscale data centers in India, and it is small, volatile and thinly covered in the US.
The broader exposure is the equipment layer, the same one we have been covering in the US. GE Vernova (GEV) closed at $957.27 on Friday and fell about 7% in Monday premarket trading, to near $887, after three AI lab chiefs called for a slowdown. The whole gas turbine and power equipment shortage we covered last month is a global bottleneck, not an American one. Korea's Hyosung Heavy is chasing the same demand from the other direction. Transformers, switchgear and batteries get sold wherever the racks go, and a meaningful share of the racks are now going to Andhra Pradesh, Maharashtra, and Tamil Nadu.
One thing to watch. India's Central Electricity Authority is moving to make states and distribution companies build projected data center demand into their resource adequacy plans, because a few states are absorbing most of it. That's the same fight playing out in Ohio and Georgia, only earlier in the cycle.
