India’s top manufacturing state Tamil Nadu has decided to drop plans for a second airport ‌to serve its capital Chennai. This information was revealed by its chief minister said on ‌Monday. This decision comes in despite calls for expanding aviation capacity to meet the needs of industry.

Chennai, dubbed India’s Detroit, is home to factories of Hyundai, Renault and Apple suppliers Foxconn and Tata Electronics.

Addotionally, the state has identified alternative locations that will have significantly less impact on agricultural land. This was revealed by Chief Minister Joseph Vijay, who ended a ‌decades-old duopoly of two ⁠major parties in May.

The Airport Project Faces Opposition

The previous government had received civil aviation clearance to develop an airport at ⁠Parandur, near Chennai at an estimated cost of 274 billion rupees ($2.86 billion). However, the project had faced opposition from farmers.

Moreover, Consultancy Colliers had stated that the airport would spur demand for industrial parks, air-cargo warehousing and manufacturing facilities nearby.

Additionally, Industry ‌lobby group Confederation of Indian Industry’s southern region chairman Ravichandran Purushothaman stated that it was important the government swiftly finalise an alternative site and prioritise the project to support Chennai’s rapidly expanding industrial, manufacturing, logistics and services sectors.

Tamil Nadu accounted for roughly 15% of India’s factories ‌and manufacturing employment. This is the highest rate among states, as revealed by a federal government statement from a year ago.

State Government to Expand An Existing Airport

Also, the state government plans to expand an existing airport. This‌ particular airport handles 30 million passengers a year. The upgraded airport will see the passenger capacity rise to 55 million by upgrading an existing terminal and building a new one. This project comes in as India gears up its aviation infrastructure, with other projects such as the Navi Mumbai International Airport in bid to become an aviation hub in Asia and globally.

Tamil Nadu signed nearly 100 investment pacts worth 674.52 billion rupees in August. This is inclusive‌ of pacts from France’s Saint-Gobain, Indian jeweller Titan and U.S. server maker Super Micro Computer.

Project Factsheet

Project Name: Chennai Second Greenfield International Airport

Nodal Agency: Tamil Nadu Industrial Development Corporation (TIDCO)

Previous Proposed Site: Parandur, Kanchipuram district, Tamil Nadu (60 km from central Chennai)

Status: Scrapped/Shelved at Parandur location; alternative, lower-impact sites currently being identified.

2. Financials and Scale

• Estimated Cost: ₹274 billion ($2.86 billion)
• Total Land Requirement: 4,750 to 5,746 acres across 13 revenue villages
• Proposed Infrastructure: Dual parallel runways, dedicated cargo village/terminals, modern passenger terminals, and an aerocity.
• Long-term Capacity: Designed to handle 60 million to 100 million passengers annually.

3. Key Issues and Primary Reason for Site Dropping

• Agricultural Impact: The proposed site encompassed over 1,300 hectares of fertile farmland, affecting roughly 12 to 13 villages.
• Environmental Concerns: Total area included 12 lakes, over 20 ponds, and natural drainage channels linked to the Palar and Cooum rivers.
• Local Opposition: Prolonged, active protests from local farmers and residents (notably from Ekanapuram and surrounding villages) over land acquisition and displacement.

4. Interim Aviation Capacity Strategy

• Existing Airport Expansion: Upgrading Chennai International Airport (MAA) to scale capacity from 30 million to 55 million passengers per year.
• Upgrade Plan: Construction of a new terminal and major enhancements to existing terminal infrastructure.
• Future Greenfield Search: Relocating the second airport project to a new location with significantly reduced agricultural and environmental impact.
