L&T Vyoma’s Chennai AI Campus: 30 MW Live, 52 MW at Groundbreaking

Two different stages30 MW: company-reported operational facility. 52 MW: groundbreaking held; described as upcoming, not operational.

The status distinction is the story: on 28 October 2026, L&T’s Vyoma.AI business announced the groundbreaking (Bhoomi Pujan) of an upcoming 52 MW AI-ready data centre in Chennai. L&T says the planned AI Factory campus already hosts an operational 30 MW facility. The 52 MW is a separate new project—not operating capacity—and the announcement gives no commissioning or service-start date, nor does it define the new facility’s MW as IT load.[1]

Not stated: new facility’s commissioning date and IT-load basis.

Do not equate the figures

30 MW facility, 52 MW new build, 150 MVA power readiness, 250 MW campus feasibility and an over-250 MW national roadmap have different scope or status. They are not a combined live-capacity figure.

30 MW live and 52 MW at groundbreaking are not interchangeable

L&T’s release describes the new 52 MW centre as upcoming and marks its groundbreaking on 28 October. In the same release, the company says the planned Chennai AI Factory campus already hosts advanced AI compute clusters in an operational 30 MW facility. This is a live-facility baseline plus a construction milestone—not 82 MW of operating capacity.[1]

Figure	What the source says	Status and boundary
30 MW	L&T says the Chennai campus already hosts an operational 30 MW facility. Vyoma’s current Chennai page lists MAA 01 at 30 MW IT load.	Existing company-reported facility. The October release does not name the 30 MW building in that sentence.
52 MW	Upcoming AI-ready green data centre; groundbreaking (Bhoomi Pujan) held on 28 October 2026.	At the groundbreaking stage in the latest announcement; not described as commissioned or operational. The release does not label the 52 MW as IT load.
150 MVA	L&T says the planned AI Factory campus is supported by 150 MVA of power infrastructure readiness.	Campus-level power-readiness wording; the release gives no allocation, energisation status or facility-by-facility split.
Over 250 MW	Vyoma.AI’s national expansion roadmap targets more than 250 MW of data-centre capacity across India.	A forward-looking company target, not current operational capacity or a Chennai-only commitment.

Do not call the campus 82 MW operational. The company describes 30 MW as an existing operational facility and 52 MW as an upcoming centre at groundbreaking. The public announcement does not say the new 52 MW is live, and it does not state that its MW basis is IT load.

What is public about the existing 30 MW facility?

The 28 October L&T release provides the status: an operational 30 MW facility already hosts advanced AI compute clusters on the planned Chennai campus. Vyoma’s current Chennai data-centre page separately lists the MAA 01 facility at 30 MW IT load. L&T’s Annual Review roadmap also lists a 30 MW Chennai site at Sriperumbudur as “Live.” These are company disclosures; the latest release does not identify the existing building by name or cross-reference each site label, so this article does not infer a separate facility count from the labels.[1][2][3]

The distinction matters for reading the new project. Vyoma’s 30 MW IT-load specification applies to the MAA 01 page entry; L&T’s 52 MW announcement simply says “52 MW data centre.” Without a published basis, it would be unsafe to assume that 52 MW means IT load, compare it directly with the 30 MW IT-load figure, or use either number to estimate usable power or GPU capacity.

150 MVA is not 150 MW of IT load

L&T’s release says the planned Chennai AI Factory campus is supported by 150 MVA of power infrastructure readiness. That is the company’s wording; it does not say how much is energised today, how much serves the existing facility, how much is reserved for the new 52 MW centre, or what remains for later phases.[1]

MVA (megavolt-amperes) measures apparent power, while MW measures real power. Converting between them requires a power factor; neither figure is automatically the facility’s IT load. A campus power-readiness statement also does not establish the amount of firm power already allocated to the new building.

Separate campus-scale wording	Source’s stated scope	How not to read it
150 MVA power infrastructure readiness	L&T’s 28 October release, referring to the planned Chennai AI Factory campus.	Not a published 150 MW IT load, and not a stated allocation to the 52 MW build.
250 MW of “power provisioning feasibility”	Vyoma’s current Chennai page; the page says the campus is ready for development to support future high-density IT load.	A feasibility statement—not proof of 250 MW energised, operational or available IT load.
Over 250 MW data-centre capacity	L&T’s national expansion roadmap for Vyoma.AI.	A pan-India target; distinct from the Chennai page’s power-provisioning-feasibility wording.
“Gigawatt-scale AI hub”	L&T’s description of its planned Chennai AI Factory campus.	A planned campus ambition, not a statement that 1 GW is built, commissioned or currently powered.

These figures are not additive. L&T’s 150 MVA readiness statement, Vyoma’s 250 MW feasibility wording, the 30 MW live facility and the 52 MW groundbreaking refer to different measures or stages. The sources reviewed do not reconcile them or map available power to the new facility.

What L&T says the 52 MW centre will include

The new centre is described by L&T as designed for high-density AI workloads. The company says it will feature direct-to-chip liquid cooling, renewable-energy integration and energy-efficient technologies, with intended services for hyperscalers, neoclouds and AI innovators.[1]

These are design intentions in the announcement—not measured operating results. The release does not give the cooling-system configuration, rack density, GPU model or count, PUE or WUE, renewable-energy share, commissioning date, capex, named customer or contract terms for the 52 MW facility. “Green” and “low-carbon” are company descriptions; no site-specific emissions or energy-mix data is included in the announcement.

Campus ambition and the national roadmap

L&T calls the planned Chennai AI Factory a “gigawatt-scale AI hub” and says Vyoma.AI is targeting more than 250 MW of data-centre capacity across India. Both are forward-looking company descriptions. The release does not provide a campus phasing schedule, a project-by-project national capacity list, or a date by which either ambition would be delivered.[1]

Vyoma’s Chennai page separately describes 250 MW of power-provisioning feasibility at the campus and lists a 30 MW IT-load facility. That statement should not be confused with the national roadmap’s “over 250 MW” data-centre target. Nor should either be used to re-label the 52 MW project as operational or to imply that the 150 MVA is already available to it.[2]

What would confirm delivery?

The next public milestones that would sharpen the status are straightforward: a dated construction or commissioning update; the 52 MW measurement basis and phase/building; a stated allocation of electrical capacity; and any customer, GPU or service-start details. Until those are disclosed, the clean reading is that one 30 MW facility is reported operational and a separate 52 MW facility has reached groundbreaking.

Quick answers

Is the new 52 MW data centre operational?

No. L&T announced a groundbreaking (Bhoomi Pujan) for the upcoming facility on 28 October 2026. The release gives no commissioning date.

What is the 30 MW figure?

L&T describes an existing operational 30 MW facility on its Chennai AI Factory campus. Vyoma’s current Chennai page lists MAA 01 at 30 MW IT load; the company release does not name the existing building in that sentence.

Does 52 MW mean 52 MW of IT load?

The October release does not specify. It calls the project a 52 MW data centre without explicitly labelling the figure as IT load.

Does 150 MVA mean 150 MW of data-centre capacity?

No. MVA is apparent power, and the source does not provide a power factor or IT-load allocation. L&T describes it as campus power infrastructure readiness.

Can the live campus be described as 82 MW?

Not as live capacity. That arithmetic would combine the existing 30 MW facility with a separate 52 MW project that is only at groundbreaking. The new project is not described as operational.

Is the “gigawatt-scale” campus already a 1 GW operating site?

No. L&T describes a planned AI Factory campus as gigawatt-scale; the release does not say 1 GW has been built, commissioned or powered.

Bottom line: The evidence supports a company-reported operational 30 MW Chennai facility and a separate 52 MW data centre that reached groundbreaking on 28 October 2026. The latter is upcoming, not operational. The 150 MVA campus-readiness figure, 250 MW feasibility wording, over-250 MW India roadmap and “gigawatt-scale” campus description refer to distinct company statements and should not be added together or treated as delivered IT capacity.
