GS Paper III: Science & Technology, Infrastructure

Current relevance:

Andhra Pradesh is emerging as India’s third major international subsea cable gateway after Mumbai and Chennai, driven by new data-centre and digital infrastructure investments.


Highlights:

Andhra Pradesh as a New Subsea Cable Hub:

1.        India's international subsea cable infrastructure is currently concentrated largely in Mumbai and Chennai.

2.      Andhra Pradesh is set to emerge as a third international subsea gateway, with new landing stations around Visakhapatnam.

3.      India-Southeast Asia (I-2SEA) Submarine Cable System is a 3,600-km cable system involving Microsoft in a consortium with firms including Lightstorm and Singapore-based Singtel.

4.      I-2SEA will connect Singapore and Malaysia with India's east coast and also connect to Chennai.

5.      The system is expected to be ready for service in Q4 2029.

6.      Google's America-India Connect system is also expected to land at Visakhapatnam, where its data-centre complex is being developed.


Terrestrial Digital Infrastructure:

1.        Subsea cable landing stations require extensive terrestrial fibre networks to carry international data traffic to inland economic and digital centres.

2.      Thousands of kilometres of new fibre infrastructure are expected to connect the new cable systems with India's major metropolitan and data-centre hubs.

3.      Lightstorm is considering a terrestrial corridor linking Machilipatnam with Hyderabad and Mumbai, alongside connectivity between Chennai, Hyderabad and Mumbai.

4.      Such infrastructure can create an additional layer of high-capacity digital connectivity between major Indian cities.

5.      Integration of subsea cables, terrestrial fibre networks and data centres is essential for translating international connectivity into a wider pan-India digital ecosystem.

6.      However, expansion faces supply-side challenges due to the global shortage of optical fibre, its components and raw-material inputs.


Data Centres, AI & Sustainability:

1.        Google's proposed Visakhapatnam data-centre facility is expected to focus primarily on AI inference rather than power-intensive AI training.

2.      The facility is intended to support domestic enterprises and government agencies, amid growing AI adoption in government-service delivery.

3.      Integration of data centres with high-capacity international subsea cables can strengthen the infrastructure required for India's expanding AI and digital-service ecosystem.

4.      Development of such infrastructure in Andhra Pradesh can help diversify India's digital infrastructure beyond established metropolitan hubs.

5.      Google intends to acquire as much renewable power as possible for the project, linking data-centre expansion with cleaner energy use.

6.      The use of air-cooling technologies to minimise water consumption also highlights efforts to reduce the resource footprint of data-centre infrastructure.


Strategic & Digital Connectivity Significance:

1.        The new subsea cable infrastructure will provide direct connectivity between India and Southeast Asia, including major digital markets such as Singapore and Malaysia.

2.      These networks can further extend India's connectivity towards Australia, the Middle East, Europe and other global markets.

3.      Several existing submarine cables serving India's east coast are relatively old, nearing capacity or approaching the end of their operational life, increasing the need for new infrastructure.

4.      A new east-coast connectivity corridor can provide alternative routes during disruptions, strengthening the resilience of India's international internet connectivity.

5.      Diversifying cable routes and landing stations can contribute to geopolitical de-risking by reducing dependence on vulnerable connectivity corridors.

6.      The emergence of additional landing locations can reduce the concentration of critical digital infrastructure in Mumbai and Chennai.

7.      Stronger direct links with Southeast Asia can enhance India's integration with regional and global digital networks.
