Key takeaways
- India added 258 MW of fresh data-centre IT capacity from January to June.
- That was 59% more than the capacity added a year earlier, Savills said.
- More cloud use and AI work are driving demand for these large computer sites.
- Power, land, water and fibre links will decide which cities grow fastest.
The data center India market grew quickly in the first half of the year, adding 258 MW of IT capacity between January and June. India data centre capacity means the computing power available in facilities that store and process digital data. Savills said the fresh supply was 59% higher than a year earlier.
Why did India data centre capacity jump?
Businesses are putting more work online, from shopping apps to bank services. They need machines that run all day, so they rent space from data-centre firms. Cloud computing means using remote computers through the internet. It lets a company avoid buying and running every machine itself.
AI is adding to that need. AI models use huge amounts of computing power while they learn and answer questions. One popular chatbot can need far more power than a simple website. As a result, firms want newer sites with dense racks of servers. The same pattern is visible across Asia, where a single announcement can move markets — shares in one Chinese firm jumped after its Zhipu data centre plan built on domestic chips.
Savills reported 258 megawatts, or MW, of fresh IT capacity in six months. A megawatt measures power. One MW equals one million watts. The figure tracks the electricity that IT equipment can use, rather than the whole building’s power draw.
What does India data centre capacity measure?
IT capacity counts the power set aside for servers, storage and network gear. It is a useful way to compare sites of different shapes and sizes. A data centre also needs cooling, lights and backup systems. Those supporting systems use extra electricity.
That extra use is often described through PUE, or power usage effectiveness. PUE compares a site’s total power use with its IT power use. A lower number means less power is lost on cooling and other support work. The Savills 258 MW figure focuses on the IT side.
| Measure | Latest January–June | Year-on-year change |
|---|---|---|
| Fresh IT capacity | 258 MW | 59% rise |
| Implied prior-year addition | About 162 MW | Base for comparison |
| Extra capacity added | About 96 MW | 258 minus 162 |
The implied earlier figure is about 162 MW. That means the latest half-year brought roughly 96 MW more capacity. It is like adding the computing power of many large office blocks in only six months.
Why are builders racing to add capacity?
India has a vast base of internet users and fast-growing digital payments. Video, games and online learning also create data that must move quickly. Sites closer to users can reduce delay. That delay is called latency. It is the wait between a click and a response.
Big cities have drawn much of the investment because they offer customers and fibre routes. Fibre is a cable that sends data using light. Mumbai has long been a key hub due to undersea cable links. Chennai, Hyderabad, Delhi-NCR, Pune and Bengaluru are also important markets.
Yet building these sites is not simple. Operators must secure large plots, reliable electricity and backup power. They also need cooling systems that work during hot weather. Local rules and water limits can shape project plans, especially in crowded cities.
The national government has pushed for stronger digital infrastructure through its Digital India programme. But rapid growth raises a hard question: where will the clean power come from? Operators are signing renewable-energy deals and seeking more efficient equipment.
What does the rise mean for investors?
The 59% increase shows strong demand, but it does not guarantee every project will succeed. A building needs customers before it earns steady rent. Operators commonly sign long contracts with cloud firms, banks and telecom companies. These contracts help make costly projects easier to fund.
Investors are watching this sector closely. Data centres need large upfront spending, then produce income over many years. This helps explain the scale of BlackRock debt backing for Meta’s El Paso data centre. Indian listed companies are restructuring around the theme too, as seen in the plan by Anant Raj to demerge its data centre and cloud business into a separately listed entity.
Demand for chips matters too. Servers need advanced processors for AI tasks. Higher chip prices could raise construction costs, as seen in TSMC’s planned chipmaking price increase. Still, companies may keep spending because digital services are now central to daily business.
What should users and cities watch next?
Watch for new project announcements, but also watch for completed sites. Announced capacity is a plan. Operational capacity is power that customers can use today. The gap can be wide because permits, power lines and equipment can take time.
Also watch electricity efficiency. A larger digital economy needs more computing, but it should not waste power. The Ministry of Power sets the wider policy setting for India’s electricity system. More renewable supply and better cooling could make the sector grow with a smaller climate cost.
India data centre capacity is growing because companies need fast, reliable computing close to their users. The next test is whether builders can deliver that power without straining city resources.
Frequently Asked Questions
What is a data centre?
A data centre is a secure building full of computers called servers. These servers store files, run apps and send information across the internet for banks, apps and cloud providers.
Why did fresh capacity rise 59%?
Companies need more cloud services and AI computing, so operators built more space for servers during the first six months. AI workloads in particular need dense, high-power racks.
How much data centre capacity did India add?
Savills said operators added 258 MW of IT capacity from January through June. That was about 96 MW more than the roughly 162 MW added in the same period a year earlier.
