ECEC covers four Indian states. It is home to 20% of India’s population and contributed about $533 billion in 2016-2017 (about 22%) to the country's GDP. The corridor region hosts 7 out of 12 of India’s major ports, namely: Chennai, Ennore, Haldia, Kolkata, Paradip, Tuticorin, and Visakhapatnam. Due to its vast scope, ECEC's development is being undertaken in phases: phase 1 covers the Visakhapatnam–Chennai Industrial Corridor (VCIC), largely in Andhra Pradesh; phase 2 involves the Chennai–Kanyakumari Industrial Corridor (CKIC) in Tamil Nadu; and phase 3 supports the Odisha Economic Corridor (OEC) and the West Bengal Economic Corridor (WBEC). GOI has selected the
Asian Development Bank (ADB) as the lead partner for developing the ECEC. The conceptualization and development of ECEC has received major support from ADB, which carried out analytical work determining the kind of infrastructure and institutional investments necessary to drive manufacturing-led growth in consultation with the Department of Industrial Policy and Promotion, GOI. ===
Visakhapatnam–Chennai Industrial Corridor=== At the heart of VCIC is a transport corridor that extends north-south over 800 km along
National Highway 16 (NH 16) on the coast of Andhra Pradesh connecting clusters where industries are located. VCIC traverses through nine districts with proximity to the urban centers of Visakhapatnam, Vijayawada, and Chennai. The corridor region accounts for more than 75% of the state's output and 4.3% of India's GDP. It is a key region for food production (especially marine products and rice), chemicals, and petrochemical products. It is also becoming a gateway for the textile movement. VCIC is designed to support the Sunrise Andhra Pradesh Vision 2029. When fully implemented, VCIC is expected to increase GDP in corridor districts by 6 times, increase manufacturing share from 9.4% in 2017 to more than 20% in 2045, and create 9.5 million jobs by 2045. Four economic nodes were identified for priority development at the conceptual planning stage, namely: Visakhapatnam, Machilipatnam, Donakonda, and Srikalahasti-Yerpedu. In close collaboration with the Andhra Pradesh government, master planning was completed for two priority nodes: Visakhapatnam (7,082 acres) and Srikalahasti-Yerpedu (Chittoor) (26,425 acres).
Chennai–Kanyakumari Industrial Corridor CKIC, the second phase of ECEC, aims to unlock the potential to accelerate manufacturing growth in the state of Tamil Nadu. Tamil Nadu already ranks high in India in terms of economic prowess and is one of the most competitive across several key indicators. CKIC’s influence area covers 23 of the 32 districts of Tamil Nadu, which accounts for 74% of the state’s population and 67% of its output. The region has a developed industrial ecosystem in key sectors such as automobiles and textiles. It has 3 major ports and 2 minor ports with a combined cargo of 240 million tonnes per year. CKIC and its infrastructure plan will be aligned with Vision 2023 of the Government of Tamil Nadu and the Sagarmala initiative with an initial focus on the southern region. Findings from the initial study identified six nodes for development, namely: Petroleum, Chemicals and Petrochemicals Investment Region (PCPIR) at Cuddalore and Nagapattinam; Ariyalur and Perambalur; Trichy-Pudukottai-Sivaganga; Madurai-Virudhunagar-Dindigul-Theni (MVDT); Ramanathapuram; and Thoothukudi and Tirunelveli (TT). With guidance from the Government of Tamil Nadu, the master planning for MVDT and TT nodes is underway.
Odisha Economic Corridor The Odisha Economic Corridor is part of the third phase of ECEC. The corridor influence area accounts for 20 districts contributing about 80% of Odisha’s output. Odisha is mineral-rich and contributes to India's steel production more than any state. With proximity to northern Indian states, it can play a crucial role in the transportation of various goods. Six nodes have been short-listed for the corridor at the conceptual planning stage, namely: Khordha–Cuttack–Jagatsinghpur (KCJ), Jajpur–Kendrapara–Bhadrak (JKB), Sambalpur–Sundargarh–Jharsuguda (SSJ), Mayurbhanj–Keonjhar–Balasore (MKB), Angul–Dhenkanal (AD), and Ganjam. In consultation with the Government of Odisha, factors such as land availability and distances from large cities, highways, and ports have been used to prioritize the two nodes of KCJ and JKB. These nodes have the key urban areas of Bhubaneswar and Cuttack.
West Bengal Economic Corridor West Bengal has the fourth largest economy in India with $155 billion in state output in 2017-2018. It is the 6th biggest contributor to India's manufacturing, and 4th biggest in India's services, which provides nearly 40 million jobs. It contributes more than 20 percent of the country’s mineral production and accounts for 10% of the country's iron and steel exports. It is India's leading state in terms of power distribution, quality and availability. It is strategically located as a gateway to northeast India and Southeast Asia, being served by key national highways and Asian highways; two large container and bulk handling ports at Kolkata and Haldia; two international airports, and several inland waterways. Conceptual development planning for WBEC is underway. The proposed spine is that along NH 16 from Sonakania to
Kolkata, and along NH 112 from
Kolkata to
Bongaon (Bangladesh border), with another fork linked to the Amritsar Kolkata Industrial Corridor through NH 60. Key industrial nodes being considered based on land availability include Goaltore (Paschim Medinipur) and Andal (Burdwan) located in Aerotropolis. The key industries identified for these potential nodes (Goaltore) based on initial assessment include fabricated metal products, machinery and equipment, and transport equipment. Potential for sub-sectors in food processing and cement are also being evaluated. == Asian Development Bank support for ECEC ==
