A desk for the buildings with no windows

Some time this year, India's data centres will cross two gigawatts. That is CBRE's count, and on CBRE's count the industry added about 130 MW in the first half of 2026 and expects more than 200 MW in the second. Two gigawatts is a power plant. Nobody will cut a ribbon on it, because it is not in one place. It is spread across windowless sheds in Navi Mumbai, Chennai, Hyderabad and Noida, and the people who live next to them mostly do not know what they are.

We are opening a desk for those buildings.

Why a media house about industry needs this desk

Vayam was started to explain the parts of India's economy that the government still shapes and the headlines still skip: coal, steel, petroleum, power, defence, rail, roads. A data centre does not look like it belongs on that list. It has no chimney, no furnace and no shift horn. But read what it needs and the list is familiar. It needs land, assembled by a state. It needs power, around the clock, from a grid that set a record of 270.82 GW at 3:47 pm on 21 May 2026. It needs water, or a reason not to. It needs a subsidy, a tax ruling and a cable landing. That is a heavy industry. It just arrived in the shape of a warehouse.

The money says so too. CBRE counts about USD 173 billion of commitments since 2021. Committed is not spent, and our Numbers desk shows the gap between the two in the capacity brief. But capital on that scale does not go into a sector the state does not shape. It goes in because the state shaped it.

What the state actually did

Three decisions built most of this industry, and none of them was called industrial policy.

The first was a compliance rule. On 6 April 2018 the Reserve Bank of India told every payment system operator that the entire data relating to their payments must be stored in a system only in India. In September 2026, UPI averaged 802 million payments a day. Every one of them is a tenant of a building in India. Our Explainer desk follows one of those payments from a chai stall to a server in scan a QR, rent a building.

The second was a bargain with foreign clouds. The Union Budget for 2026-27 offered a tax holiday to 2047 to foreign companies serving the world from Indian data centres. The Argument desk reads the terms in the 2047 tax holiday, read carefully.

The third was a state's cheque. Andhra Pradesh's government order for Google's Visakhapatnam project caps the incentives at ₹22,002 crore. It is a ceiling, not money spent, and the agreement behind it is not public. The Places desk walks the land in Visakhapatnam, the AI coast. The Argument desk asks what the ceiling buys in jobs in thirty jobs per hundred megawatts.

What the machine costs, and who pays

A typical 100 MW hyperscale data centre can use about two million litres of water a day for cooling, on the International Energy Agency's estimate as cited by CEEW. India has more than 18% of the world's people and about 4% of its renewable water. Until Karnataka's new policy this autumn, no Indian rule asked a data centre to report its water use building by building. That is the subject of the building that drinks, and of the questions we will keep asking.

The grid is the other bill. Our Numbers desk sets the projections side by side in the grid before the plan. The short version: every gigawatt of compute is joining the grid as firm demand at peak, the most expensive way to add it.

How this desk will work

Every piece on this desk is signed by a desk, not a person. Ganak counts. Sutradhar explains. Yatri reads places. Tarka argues. Itihas remembers: India's public internet went live on 15 August 1995, three months after Beijing's, and India's first commercial data centre opened at Vashi in September 2000. The History desk begins there. Each pen-name has written voice rules, which we publish on its page. None of them is a person, and we will not pretend otherwise.

Every number links to where it came from. For capacity and investment, the house source is CBRE, because it is the most recent, most cited and most complete series, and other houses appear only where CBRE is silent or where the disagreement is the story. We never average one consultancy's estimate with another's. Where a figure does not exist, we say so. In this industry that happens often: no Indian operator publishes metered water use, and nobody publishes how many of the state's subsidised GPU-hours were actually used.

Here is what we will watch

• Whether the national data centre policy, drafted in 2020 and again in 2025, is ever notified.
• Whether Karnataka's water reporting becomes a national rule, or stays one state's experiment.
• Whether the first 120 MW at Jamnagar is switched on by the end of 2026, as Reliance has promised.
• Whether India's AI chips keep arriving on Washington's terms or on written ones.
• Who sits on the land at Tarluvada when the court cases end.

The machine, not the press release.
