India Projects 22% Annual Solar Growth Through 2035, Fueled by Data Centers and AI Demand

The Numbers

India's total electricity consumption currently sits at roughly 1,848 billion units (BU), according to a June 15 report by Nuvama cited by Economic Times Energy World. Nuvama projects that figure reaches 3,228 BU by FY35, an increase of more than 1,380 BU over the decade.

Overall power demand grows at a 6% compound annual rate. Solar grows at 22%.

Solar's share of total installed generation capacity is projected to climb from 28% in FY26 to 61% by FY35 in the base case, and 65% in a bull case, according to Nuvama. In terms of consumption, solar goes from 9% to 33% of total power used.

What's Driving It

Data centers are the primary accelerant. As Economic Times Datacenters reported on June 15, electricity accounts for 30% to 40% of a data center's operating expenses. That makes cheap renewable power a direct cost-control strategy, not just a PR play.

The Nuvama report specifically names AI as a structural demand driver. New model families—GPT, Gemini, DeepSeek—require meaningfully more compute and therefore more electricity than prior generations. India's data localization regulations, which require certain categories of data to be stored domestically, are concentrating that buildout inside the country.

Green hydrogen adds to the load. Nuvama estimates that data centers and green hydrogen production alone will require an additional 251 GW of solar capacity in the base case, and 406 GW in the bull case.

For comparison: India added 145 GW of total solar capacity across the entire decade from FY16 to FY26. The base case calls for 416 GW of incremental solar additions over FY26 to FY35, according to Economic Times Datacenters.

Government Targets Back It Up

India's Central Electricity Authority published a Generation Adequacy Plan earlier this year projecting 509 GW of installed solar capacity by the end of FY2035-36, up from 140 GW as of January 2026. That's roughly a 3.6x increase. The government also targets tripling wind capacity over the same period.

India cleared a notable milestone in 2025, reaching the point where 50% of installed electricity capacity came from non-fossil fuel sources—five years ahead of its own schedule, according to ZeroHedge's sourced reporting from OilPrice.com.

The Grid Problem

The legitimate concern here is infrastructure, not ambition. India's electricity transmission grid is not expanding at the same pace as its renewable generation capacity, ZeroHedge noted, citing OilPrice.com analysis. The result is increasing curtailment: clean energy gets generated but can't be moved to where it's needed, so it gets wasted.

Curtailment is a real brake on the economics of solar investment. If a solar plant generates power that the grid can't absorb, the returns collapse and future capital deployment slows. Skeptics of the 22% CAGR projection point to this mismatch as the most plausible reason the targets come in below forecast.

The government's own plan acknowledges that renewable capacity must be "supported by Energy Storage Systems," a tacit admission that intermittency and grid absorption are unsolved problems at scale.

Those concerns are fair and grounded in current data. What they don't change is the direction of travel. The data center buildout isn't theoretical. It's being driven by contractual electricity demand commitments from operators who have strong financial incentives to lock in renewable supply now.

Silver and Downstream Effects

Canadian Mining Report, writing on June 16, flagged a downstream consequence that the Indian energy coverage largely ignored. Solar photovoltaic cells use silver in conductive pastes. China has been the dominant driver of solar-related silver consumption for years, but Canadian Mining Report's analyst Ben McGregor argues China's installation pace may be normalizing as its existing base matures.

If India's 22% CAGR materializes, McGregor writes, it could offset any deceleration in Chinese solar silver demand and sustain elevated industrial silver consumption through the early 2030s, even accounting for ongoing "thrifting"—the industry term for reducing silver content per panel over time.

This is a projection built on a projection, so it carries compounding uncertainty. But it's a concrete second-order consequence that energy analysts covering India have largely not addressed.

The Open Question

Nuvama's 22% CAGR figure assumes the data center pipeline converts from announced to operational at scale. India's grid expansion timeline is the variable that neither the Nuvama report nor the government's Generation Adequacy Plan fully resolves. Whether transmission infrastructure investment accelerates fast enough to prevent curtailment from choking the solar buildout is, as of June 16, 2026, genuinely unanswered.
