India’s Data-Centre Boom: Decoding the Infrastructure Gold Mine

As India’s digital transformation accelerates, the nation is undergoing a massive infrastructure overhaul. With live data-centre capacity having surged to approximately 1.8 GW—a figure buoyed by a record-breaking 258 MW addition in the first half of FY27—the market is poised for exponential growth. Current projections suggest that India’s capacity will hit 10.5 GW by 2031, a monumental shift that has investors pivoting their focus from quarterly earnings to the robust order books of key infrastructure players.

The artificial intelligence (AI) build-out serves as the primary catalyst for this capital expenditure cycle. For market participants, an order book is more than just a list of future projects; it is a vital indicator of revenue predictability in an era of rapid technological expansion. Three major players have emerged as central architects of this digital ecosystem, each capturing a different slice of the value chain.

Larsen & Toubro: The Engineering Giant

Larsen & Toubro (L&T) remains the cornerstone of India’s construction landscape. With a consolidated order book that hit a staggering Rs. 8,53,500 crore by the end of September 2026, the company is reaping the rewards of a diversified portfolio. L&T is not merely building skyscrapers; it is positioning itself as a dominant force in semiconductors, green hydrogen, and data-centre facilities.

The company’s recent performance, characterized by a 33% jump in profit after tax to Rs. 5,200 crore, underscores its ability to convert record-high inflows into tangible results. With a near-term addressable pipeline of Rs. 10 lakh crore, L&T is effectively leveraging its massive balance sheet to spearhead India’s most critical infrastructure projects.

Power Mech Projects: Lighting the Future

To support the massive power demands of AI-driven data centres, companies like Power Mech Projects are becoming essential. Specializing in integrated industrial construction and operations, Power Mech maintains a client roster that includes industry titans such as Adani, NTPC, and JSW.

The firm is shifting its strategic focus toward high-margin operations and maintenance, alongside an integrated balance-of-plant delivery model. With an order backlog of Rs. 56,650 crore, Power Mech is not just benefiting from short-term construction booms but is securing long-term revenue streams through multi-decade mining contracts and ongoing industrial infrastructure support.

Sterlite Technologies: Connecting the AI Era

If construction and power form the body of the data-centre revolution, optical connectivity provides the nervous system. Sterlite Technologies (STL) has become a primary beneficiary of this trend, leveraging its “Neural” portfolio to serve hyperscalers and cloud providers globally.

STL’s order book has seen a meteoric rise, expanding 4.6 times since the start of the year to reach Rs. 35,274 crore. With data centres now contributing a third of its total revenue, the company is setting ambitious targets for EBITDA margins, aiming to exceed 30% by FY29. Its position as a premier end-to-end optical manufacturer makes it an indispensable partner in the global race for AI-ready bandwidth.

The Investor’s Lens

While the data-centre expansion presents a compelling narrative, investors are advised to exercise caution. The sustainability of this infrastructure cycle rests heavily on the continued capital commitment of global hyperscalers, which could face headwinds if funding costs escalate.

A large order book serves as a strong beacon for future revenue, but it does not guarantee execution success or immunity from market volatility. Discerning stakeholders must scrutinize factors such as project quality, management discipline, and valuation metrics. As India continues to build the digital backbone of the future, those who differentiate between hollow growth and sustainable value will likely be the primary beneficiaries of this transformation.
