Data Centres & Environment: Vizag and Beyond
India’s AI Ambitions Face an Environmental Test
As India races to become a global hub for artificial intelligence, cloud computing, and digital infrastructure, a new environmental debate is emerging around the rapid expansion of hyperscale data centres. Nowhere is this debate more visible than in Visakhapatnam (Vizag), where billions of dollars of investments are transforming the coastal city into a major AI and cloud-computing gateway. While these projects promise jobs, economic growth, and technological leadership, concerns are growing over their impact on water resources, energy consumption, land use, and climate sustainability.
Vizag: India’s Emerging AI Data Centre Capital
The Andhra Pradesh government has positioned Vizag as a future digital infrastructure hub. Major projects include Google’s proposed AI hub and hyperscale data centre campus, along with investments from multiple domestic and international operators. Government leaders have described Vizag as a future AI gateway supported by subsea cable connectivity, cloud infrastructure, and large-scale computing facilities.
Recent agreements and investments indicate plans for several hundred megawatts to gigawatts of future data-centre capacity, potentially making Vizag one of the largest data-centre clusters in Asia.
The Water Challenge
The biggest environmental concern surrounding data centres is water.
AI servers generate enormous heat and require extensive cooling systems. Although some modern facilities use advanced cooling technologies, water remains a critical resource for many operations. Environmental researchers have highlighted a paradox: while Vizag is attracting water-intensive digital infrastructure, the district itself has limited groundwater availability compared with many other regions of Andhra Pradesh.
Local authorities have already begun planning future water management strategies, including water budgeting exercises, desalination projects, tertiary-treated wastewater reuse, and dedicated supply infrastructure to support future demand from IT parks and data centres.
The Andhra Pradesh government has stated that adequate water and power supplies will be ensured for major projects, reflecting official confidence that infrastructure can keep pace with industrial growth.
Energy Demand and Carbon Footprint
Beyond water, data centres require massive amounts of electricity.
A hyperscale AI facility can consume power comparable to a medium-sized city. As India expands AI infrastructure, concerns arise regarding whether electricity demand will be met through renewable sources or fossil-fuel-based generation. Experts note that the environmental footprint of AI depends not only on data-centre operations but also on the energy mix powering those facilities.
For Andhra Pradesh, balancing AI-driven growth with renewable energy deployment will be crucial to maintaining climate commitments while supporting economic expansion.
Coastal Opportunities and Risks
Vizag’s coastal location offers unique advantages.
The city has access to international subsea cables, port infrastructure, and the possibility of using desalinated seawater or seawater-based cooling systems to reduce pressure on freshwater resources. Andhra Pradesh’s policy framework has discussed leveraging seawater cooling technologies for future data-centre developments.
However, environmental experts caution that coastal ecosystems must also be protected. Large industrial developments can affect land use, biodiversity, coastal hydrology, and local communities if environmental safeguards are not rigorously implemented.
Beyond Vizag: A National Issue
The environmental debate extends far beyond Andhra Pradesh.
Across India, data centres are rapidly expanding in states such as Maharashtra, Tamil Nadu, Karnataka, Telangana, and Uttar Pradesh. Many of these regions already face seasonal water shortages, groundwater depletion, or increasing climate-related stress. As AI adoption accelerates, policymakers are being urged to develop national standards for:
- Water-use efficiency
- Renewable-energy integration
- Waste heat management
- Environmental disclosure requirements
- Sustainable cooling technologies
- Recycled-water utilization
These measures could help ensure that India’s digital transformation does not create unintended environmental costs.
Industry Response
Technology companies argue that significant progress is already being made. Amazon recently announced that its Indian operations have become “water positive” and stated that its Indian data centres do not use water-based cooling systems. Other operators are investing in closed-loop cooling, recycled-water systems, and renewable-energy procurement to reduce environmental impacts.
Meanwhile, local governments are exploring desalination plants, treated wastewater reuse, and AI-assisted groundwater monitoring to better manage future demand. An AI-powered groundwater dashboard developed by researchers in Vizag is one example of how technology itself can contribute to sustainable resource management.
The Way Forward
Vizag represents both the promise and the challenge of India’s AI future. The city could emerge as a globally significant digital hub, attracting investment, employment, and innovation. At the same time, it serves as a reminder that digital infrastructure is not “virtual”—it depends on real-world resources such as water, electricity, land, and ecosystems.
The long-term success of India’s AI economy may depend not only on computing power and investment but also on how effectively governments, technology companies, and communities balance digital growth with environmental sustainability. In that sense, the story of Vizag is not merely local—it is a preview of the environmental questions that AI-driven development will raise across India and beyond.
As Vizag emerges as a major AI data-centre hub, concerns grow over water use, energy demand, and environmental sustainability. Explore the opportunities and challenges shaping India’s digital future.
