The hidden costs of India's data centre ambitions

The AI juggernaut is hardly new, but it is rolling along merrily, with leaders falling over themselves to proclaim the next great technology boom. Headlines and photographs celebrating the frenzy are everywhere. India too wants to become a global data centre hub, with billions of dollars in investments being announced. The promise is enormous: jobs, growth and technological leadership.

But there is a catch: data centres need vast amounts of water and electricity, land and dependable infrastructure—resources that are neither limitless nor uniformly available across India.

There is another side to this cloud, and it has no silver lining. While investment announcements celebrate computing capacity and economic opportunity, the costs borne by the communities hosting these facilities risk being overlooked. A data centre may power the digital economy, but if it strains local water supplies, electricity networks and civic infrastructure, its promise of progress comes with a very real price tag. That is a trade-off India must confront before embracing the boom uncritically.

Water is not unlimited

Water is the immediate concern. Data centres generate enormous amounts of heat and their cooling requirements can place massive demands on local water resources. The precise need varies with the facility’s size, location and cooling technology, but the implications become serious when projects are located in water-stressed regions.

Research by WRI India, published in May 2026, found that more than half of India’s data centres are situated in water-stressed areas. A Council on Energy, Environment and Water study also highlighted the growing water and energy footprint of the sector.

Therefore, the question is not whether technology can reduce consumption. It can. Advanced cooling systems and recycled or treated water can help. The core question is whether the source, availability and long-term sustainability of water are studied and weighed before a project receives approval. A facility cannot be allowed to turn an existing scarcity into a grievous problem for nearby communities.

The power equation

Electricity presents an equally daunting challenge. Data centres operate around the clock, requiring reliable power not only for computing but also for cooling and backup systems. Renewable energy can reduce their carbon footprint, but round-the-clock demand requires careful planning of generation, storage, transmission and dependable supply.

India’s installed power capacity and renewable energy expansion are clear advantages. Yet aggregate capacity does not automatically translate into adequate, uninterrupted electricity at every location where a data centre is proposed. Transmission infrastructure, grid reliability and competing demands must also enter the calculation.

The same principle applies to land, roads, drainage and other civic infrastructure. A project that looks viable on an investment presentation may impose very different costs on the locality where it is built. All these costs must be assessed before construction, rather than left to be managed after residents begin raising objections.

Lessons from the world

India is not alone in confronting these tensions. Communities in the United States and Europe have long questioned the water, electricity, noise and environmental consequences of large data centre projects. India is now witnessing similar concerns.

Protests by residents around a proposed Amazon data centre in Thane have raised questions about water supplies, electricity demand and neighbourhood impact. Google’s proposed data centre development in Andhra Pradesh has attracted scrutiny over resource requirements and environmental concerns. This is not a case against any company or investment. Nor do objections automatically establish that a project is unviable. They only underline the need for transparent assessments, credible safeguards and meaningful engagement with the people who will live near these facilities.

India should resist the temptation to treat every global investment announcement as an unqualified endorsement of its infrastructure readiness. Projects that encounter resource constraints or public resistance elsewhere do not become sustainable merely because they move to a different country. The conditions that made them contentious there must be examined before they are replicated here.

Accountability is key

The answer is neither to discourage investment nor to dumb down technological progress. It is to establish clear ground rules for responsible expansion. All projects should disclose expected water and electricity needs, identify sources of supply, explain cooling arrangements and demonstrate how they will avoid compromising local needs.

Environmental assessments and public consultations must be meaningful. Regulators should monitor consumption against commitments, with enforceable safeguards where necessary. Governments, developers and communities all have a stake in making this work. Predictable rules and reliable infrastructure will benefit investors as much as residents.

India has a unique opportunity to become a major global data centre hub. But the measure of success should not be the number of projects announced, the billions in capital committed or the computing capacity installed. It must also include the quality of infrastructure created, the resources conserved and the interests of communities protected.

A digital superpower cannot afford to overlook the physical foundations of its ambitions.
