The Dholera semiconductor cluster, mapped: what is built, what is allotted, and what is still paper

Published 25 August 2026. Facts verified to 25 August 2026 unless dated otherwise.

A cluster map is worth reading only when it separates serviced ground from allotted plots, allotted plots from construction, and construction from press releases.

What this map shows, and the frame it sits in

Dholera coverage collapses four different states of reality into one word. Serviced ground, allotted plots, plants under construction and announcements all get called development, which is how a corridor with a single large plant rising acquires a reputation for being either finished or fictional depending on who is writing. This page keeps the four apart. An element earns a location on this map when a government instrument, an allotment record or a dated construction report puts it somewhere specific. Everything else waits in the last section, where the gigawatt announcements sit without plot numbers.

Every figure below carries a date and a named source, because a cluster map without dates is a brochure. The reference documents here are the delivery record maintained by the National Industrial Corridor Development Corporation with the Department for Promotion of Industry and Internal Trade, which states the position as of 31 May 2026, the special economic zone notification issued by the Ministry of Commerce and Industry, the Union Cabinet decisions of 29 February 2024 and 5 May 2026, and the Central Electricity Authority quarterly reporting for the solar park. Where reporting is single-sourced, this page says so rather than upgrading it by omission.

Dholera Special Investment Region extends to roughly 920 square kilometres, of which about 580 square kilometres are developable and about 422 square kilometres urban-developable under a phasing that planning documents spread across roughly three decades. Those are planning envelopes, not built area, and reading them as built area is the single most common error in Dholera commentary. Six town planning schemes are sanctioned. Phase 1 concentrates on the first two, about 153 square kilometres combined, and inside them sits the Activation Area of about 22.5 square kilometres where trunk infrastructure landed first. The delivery record for 31 May 2026 lists trunk infrastructure works in that Activation Area as complete DURABLE.

That concentration is deliberate rather than cosmetic. Servicing 900 square kilometres at once is fiscally impossible, so a greenfield region builds one working zone and lands its anchor tenants on it. Every widely circulated construction photograph of Dholera is a photograph of this zone. Land reaches an occupier through the town planning scheme machinery rather than through private assembly, and that mechanism is why allotments can be counted at all.

The anchor plot: 66.16 hectares with a fab on it

The centre of the map is the Tata Semiconductor Manufacturing plant, cleared by the Union Cabinet on 29 February 2024 at Rs 91,000 crore, with the Fiscal Support Agreement of 5 March 2025 citing Rs 91,526 crore and central support covering 50 percent of eligible project cost DURABLE. Designed capacity is up to 50,000 wafer starts per month on 300mm wafers, with the approval record naming a 28 to 110nm band and products including power management chips, display drivers, microcontrollers and logic. The special economic zone notified for the company on or about 16 April 2026 covers 66.16 hectares DURABLE, which is where the plant's boundary becomes a legally described object rather than a dot on a masterplan. The SEZ file covers what that status changes and, more usefully, what it does not.

Construction status is the part most often overstated. Civil work stood at about 50 percent as of mid-2026 with cleanroom fit-out under way, which is a long way from structurally complete. The opening node is genuinely disputed on the record: Bloomberg reported on 17 July 2026 that the plant will open mostly at 90nm, TrendForce carried the same reading on 20 July 2026, and the company's own position remains a 28 to 110nm range, with the Tata Sons chairman's letter in the FY25 annual report saying the fab would start at 28nm REPORTED. This record does not resolve that contradiction, because nothing in the public domain resolves it. On timing, no first-silicon date is supported by any source. Commercial production is guided to mid-2028 by the electronics and information technology minister, Ashwini Vaishnaw, on 17 July 2026 TARGET. The progress-report investigation works through the underlying document.

The allotment register: twelve plots, 436 acres, one named anchor

The delivery record for 31 May 2026 counts twelve plots allotted at Dholera, of which 436 acres are industrial, with Tata Chemicals named as an anchor investor and further industrial and commercial land recorded as readily available DURABLE. That single paragraph is more informative than any investment total published about Dholera, because allotment is a transaction with a counterparty, an area and a use, while an investment headline is a sentence.

Two readings follow from it. The first is arithmetic: 66.16 hectares is about 163 acres, so the fab alone accounts for close to 38 percent of all industrial land allotted so far. One project dominates the register. The second is what the register does not contain. There is no public plot-by-plot map naming every allottee, no published schedule of lease commencement dates, and no official statement of how much of the 436 acres has moved from allotment to construction. Anyone drawing a dense cluster diagram of Dholera today is drawing from announcements, not from the register.

The supplier layer, and the only part of it pouring concrete

A fab pulls its heaviest suppliers over the fence, because bulk nitrogen and ultrapure water cannot be trucked economically at the volumes a 50,000 wafer per month plant consumes. At Dholera the visible piece of that layer is INOX Air Products, reported to be building an electronic specialty gas hub of about Rs 500 crore with a 200 tonne per day air separation unit, with construction reported from October 2025 and the cold box structure reported erected REPORTED. Our company file holds the detail and the sourcing caveats. Linde has been reported, from trade press only and at low confidence, to be advancing plans for a Dholera production plant, and Fujifilm India signed a memorandum of understanding with the Gujarat State Electronics Mission on 30 June 2026 to explore a semiconductor materials base. Explore is the operative verb and it is being used literally.

The second approved plant, and why it is a different business

The Union Cabinet approved two further semiconductor units on 5 May 2026 with a combined investment stated at Rs 3,936 crore, one of them Crystal Matrix Limited's integrated compound semiconductor fabrication and packaging facility at Dholera DURABLE. The announced capacity is 72,000 square metres a year of Mini and Micro-LED display panels together with 24,000 sets of red, green and blue gallium nitride epitaxy wafers, with gallium nitride foundry services including epitaxy on six-inch wafers. The stated build sequence puts the fabrication unit at about two years and the packaging unit at about one and a half years, running in parallel.

Cabinet approval is a materially stronger instrument than a memorandum, because it commits central incentive money under a notified scheme. It is still not construction. No ground-breaking, contractor award or plot number for this unit has been published, and until one appears the honest place for it on the map is approved, not building. It also belongs to a different technology family from the silicon plant next door, which the display question guide unpicks, since compound semiconductor work on gallium nitride shares a corridor with silicon logic but almost none of its process.

Power and water: trunk capacity with dates attached

Of the Dholera solar park's 1,000 MW Phase I, 300 MW built by Tata Power Solar is commissioned and 700 MW sits under development across ReNew, SJVN, Vena and TEQ Green, logged in the Central Electricity Authority's September 2025 quarterly report, against a stated Phase I completion of March 2027. A fab does not run on solar alone, since wafer processing is a continuous load and photovoltaics are not, so the meaningful reading of the park is corridor supply and corporate power purchasing rather than direct plant supply. The power infrastructure guide handles the grid side.

Water is the tighter constraint and the record is honest about it. Desalination capacity at Dholera is reported at about 20 million litres a day, and a tender was issued on 9 July 2026 to appoint consultants for a 200 million litre per day seawater desalination plant. Appointing consultants is the start of a procurement cycle, not the end of one, and the gap between 20 and 200 is the gap between servicing a fab and servicing a fab plus the data centre campuses that keep being announced around it. The Gujarat Semiconductor Policy 2022-27 carries a 50 percent capital subsidy on a desalination plant built within the first five years, which tells you the government identified the same constraint.

Access: the road that opened, the runway that has not

The 109 km NH-751 expressway from the Ahmedabad ring road side to Dholera opened to traffic on 31 March 2026 and is the only one of the three access projects in service today. The airport, built by Dholera International Airport Company Limited as a joint venture of the Airports Authority of India, Gujarat and the national corridor development body, has a 3,200 metre code 4E runway with a 2,500 square metre cargo terminal in Phase 1, recorded a first Airports Authority trial landing on 4 June 2026, and was described by the civil aviation minister on 14 July 2026 as roughly 80 percent complete with operations likely in September or October 2026 TARGET. The semi high-speed rail link from Sarkhej was cleared by the Cabinet Committee on Economic Affairs on 13 May 2026 at about Rs 20,667 crore for a 220 km per hour design and a 34 minute journey, which places it years behind the road in delivery terms.

For a semiconductor cluster the cargo terminal matters more than the passenger terminal. Wafers, masks and spare modules move by air in small, high-value, tightly controlled consignments, and a corridor without a working air freight route runs its logistics through Ahmedabad and Mumbai by road until the runway opens.

The paper layer: gigawatts without plot numbers

Around the built and approved elements sits a much larger announced layer, and it deserves a separate section precisely because it keeps getting drawn onto maps. L&T's Vyoma venture has a reported Rs 25,000 crore plan for a 250 MW artificial intelligence ready campus with operations around 2028, carried by the government's News on Air service REPORTED. Adani's reported hub of up to 7.5 GW is discussed at roughly Rs 3 lakh crore, a figure our capital ledger holds at announcement tier and has not traced to a company filing, and Tillman Global's hyperscale plan is reported at about Rs 83,000 crore from a single source, which is a weakness in the sourcing rather than a detail. None of these has a published plot number, land allotment, power purchase counterparty or financial close. The data centre hub guide tiers each one individually.

Policy has moved faster than any of them. The Viksit Gujarat Data Centre Policy 2026-29, announced on 9 July 2026, sets a 150 MW minimum information technology load to qualify, adds a 2.5 percent capital subsidy specific to projects inside Dholera Special Investment Region, and carries a power tariff subsidy of Rs 1 per unit with electricity duty reimbursement for twenty years. A policy written for hyperscale campuses is evidence of intent and of competition with other states. It is not evidence of a campus.

What to watch, in order of information value

• The next delivery record update, and whether allotted industrial acreage moves materially above 436 acres with named allottees.
• Commissioning of the air separation unit, which would make the gas layer an operating fact rather than a construction report.
• Any construction instrument for the compound semiconductor unit: contractor award, ground-breaking, or a plot reference.
• Bulk water, specifically whether the 200 million litre per day desalination project moves from consultant appointment to tender award.
• The balance 700 MW of solar against the March 2027 Phase I date, and the airport against its September to October 2026 window.
• Tool move-in at the fab, which is the milestone that converts a building into a plant and is visible through equipment orders rather than statements.

A cluster becomes real when a second occupier arrives because the first one is there, not because a policy invited it. Dholera has one anchor building, one compound unit approved, one gas plant reported rising and a long list of announcements. That is an early cluster with a credible spine, and describing it as anything denser would require documents nobody has published.
