CHENNAI: The Tamil Nadu government on October 15 launched the Tamil Nadu Semiconductor Ecosystem Scheme 2026, offering a state subsidy of 15% to 25% of eligible capital expenditure for chip projects approved by the Centre.[8][2] On the same day, CapitaLand Investment unveiled CapitaLand Data Centre Chennai 01 in Ambattur, the first Tamil Nadu data centre of CapitaLand India Trust, with a planned investment of about Rs 1,940 crore.[1][4] Singapore Deputy Prime Minister Gan Kim Yong attended the unveiling with Chief Minister C Joseph Vijay.[4][1]
The Tamil Nadu Semiconductor Ecosystem Scheme 2026
The scheme offers incentives across semiconductor manufacturing, equipment, materials, advanced packaging and testing.[8] It works on two tracks. Track 1 adds a state investment promotion subsidy on top of central support for projects approved by the Centre. Track 2 offers customised, need-based incentives to strategically important projects that are not covered by central schemes.[10][11]
| Project Category (Track 1) | State Subsidy on Eligible Capex | Notes |
|---|---|---|
| 300-mm silicon wafer fabrication | 25% | In addition to the Centre's 40% |
| Advanced packaging | 25% | Chiplets and heterogeneous integration included |
| Legacy packaging | 20% | As listed in the scheme |
| Semiconductor-grade raw materials, testing and characterisation, equipment R&D | 15% | Lowest tier |
| Track 2 projects outside central schemes | 15% to 25% fixed capital subsidy | Plus turnover subsidy up to 2% a year for five years |

On Depth Grid's calculation, a 300-mm fab approved by the Centre could receive combined support of about 65% of eligible capex, from 40% central and 25% state assistance.[8] Eligible projects can also receive a 5% interest subsidy on term loans for six years.[8] Proposals must reach Guidance Tamil Nadu on or before September 30, 2027.[8][3]
The scheme sets local hiring conditions, which a trade report puts at 50% of the direct workforce and 60% of high-value jobs paying above Rs 25,000 a month going to Tamil Nadu domiciles.[12] Eligibility under Track 1 is confined to companies that already have approval from the Government of India, which links the scheme to central programmes such as the India Semiconductor Mission and its second phase, Semicon 2.0.[2][12]
CapitaLand's Chennai Data Centre
| Parameter | Detail |
|---|---|
| Facility | CapitaLand Data Centre Chennai 01, Ambattur |
| Owner | Jointly held by CapitaLand India Trust and CapitaLand India Data Centre Fund |
| Planned investment | About Rs 1,940 crore |
| IT power capacity | 34 MW across 13 data halls |
| Gross power capacity | 53 MW on completion, targeted by end of 2026 |
| Power infrastructure | Dedicated 110 kV substation |

CapitaLand India Trust is a Singapore-listed business trust focused on India. The data centre is its first in Tamil Nadu.[5][6] CapitaLand Investment said the project builds on a 22-year presence in the state, where it has invested more than Rs 6,000 crore across seven operational assets.[6] The Rs 1,940 crore planned investment is equal to about a third of that existing base, on Depth Grid's calculation. The Industries Minister said Tamil Nadu would welcome Singapore companies in emerging sectors such as semiconductors. Enterprise Singapore is named among the supporting agencies.[4][6]
Two capacity figures appear in reports. The 34 MW figure refers to IT power and the 53 MW figure to gross power, which includes cooling and other overheads, so IT power is about 64% of gross power, on Depth Grid's calculation. The planned investment works out to roughly Rs 57 crore for each MW of IT capacity, also on Depth Grid's calculation. Reports differ on whether the ceremony was on Thursday or Friday. The facility is due for completion only by the end of 2026, so it is not yet fully built.
Why Chips and Data Centres Are Moving Together
Both announcements target the same demand base. AI workloads need data centres with dependable power. Chip makers need clusters of suppliers, power and skilled labour. Dataquest noted that the CapitaLand investment sits alongside the new Tamil Nadu scheme and a Rs 10,000 crore, 150 MW AI facility plan by CtrlS in Bihar.[13] In June 2026, Larsen and Toubro agreed to invest about Rs 18,600 crore in Tamil Nadu in plans that cover electronics manufacturing and a data centre, according to the state government.[5]

Strategic Implications for Chipmakers, Developers and States
The scheme does not create a fab by itself. Track 1 only applies to projects that already have central approval, so its practical effect depends on how many such projects choose Tamil Nadu. The 25% state support on top of 40% central assistance makes the state more competitive on capital cost, but land, power, water and skilled labour decide final location.
For data centre developers, the CapitaLand project shows continued appetite from global real-asset managers for Indian capacity. Ambattur is an established data centre corridor. For other states, the move raises the bar in the competition for chip investment, which Depth Grid's report on Q3 global venture funding shows is drawing growing private capital.
Four items to watch are the first applications to Guidance Tamil Nadu, the central approvals that make projects eligible, completion of the Chennai facility by the end of 2026 and any further state schemes. The Ministry of Electronics and Information Technology and the India Semiconductor Mission publish the central framework that the state scheme depends on.
Common Questions and Direct Answers
What is the Tamil Nadu Semiconductor Ecosystem Scheme 2026?
It is a state incentive scheme launched by Chief Minister C Joseph Vijay on October 15, 2026 to attract investment in semiconductor manufacturing, equipment, materials, advanced packaging and testing. Track 1 adds a state subsidy of 15% to 25% of eligible capital spending on projects approved by the Centre. Track 2 offers customised incentives for strategic projects outside central schemes.
How much subsidy does Tamil Nadu offer for chip projects?
A 300-mm silicon wafer fab can receive 25% of eligible capital expenditure from the state, on top of the Centre's 40%. Advanced packaging gets 25%, legacy packaging 20% and materials, testing and equipment research facilities 15%. Track 2 projects can get a 15% to 25% fixed capital subsidy plus up to 2% turnover support for five years.
What is CapitaLand's Chennai data centre?
CapitaLand Data Centre Chennai 01 is the first Tamil Nadu data centre of CapitaLand India Trust, located in Ambattur. The planned investment is about Rs 1,940 crore. It will have 34 MW of IT power across 13 data halls and 53 MW of gross power capacity on completion, which is targeted for the end of 2026.
Who can apply for the Tamil Nadu semiconductor subsidy and by when?
Proposals must be submitted to Guidance Tamil Nadu on or before September 30, 2027. Track 1 eligibility is limited to companies that already have approval from the Government of India under the central semiconductor schemes. Track 2 covers strategically important projects outside the central schemes. Final benefits depend on eligibility conditions in the scheme document.
What local hiring conditions does the scheme set?
The scheme document and a trade report say at least 50% of the total direct workforce must be Tamil Nadu domiciles, along with 60% of high-value jobs paying more than Rs 25,000 a month. Depth Grid has not verified the full text of these conditions, so applicants should read the scheme document and confirm the exact definitions.
