- Operating capacity approaches 2 GW; major projects promise expansion
- Continuous demand supports renewables, storage and dependable grid supply
India’s data centre expansion is creating a new source of electricity demand. Beyond increasing consumption, investments in cloud computing and artificial intelligence are turning technology companies into long-term buyers of renewable power.
Research cited in recent industry coverage estimates that renewable capacity required to serve Indian data centres could rise from 16.1 GW in 2026 to 32.4 GW by 2030, alongside an increase in IT load from 2.7 GW to 5.4 GW. These are modelled requirements, rather than projects already commissioned or contracted.
The opportunity is substantial, but operating facilities, proposed campuses and future power requirements must be assessed separately.
Operating capacity approaches 2 GW
The government reported approximately 1,575 MW of installed data centre capacity in August 2026, compared with 375 MW in 2020. CBRE separately estimated approximately 1,750 MW of operational capacity at end-June, following additions of around 130 MW during H1 2026.Different coverage and definitions mean these estimates are not directly interchangeable.
CBRE expects more than 200 MW of additional supply during H2, taking operational capacity towards 2 GW by year-end. Mumbai accounts for approximately 52% of its operating-capacity estimate, followed by Chennai at 18%, Delhi NCR at 11%, Pune at 8% and Bengaluru at 7%.
The industry extends beyond global technology companies. Airtel reported approximately 300 MW at Nxtra in March 2026. IFC disclosures identify around 188 MW of built IT capacity across Sify’s 14 operating facilities, with another 11 under development. STT GDC India describes a portfolio exceeding 400 MW, including development capacity. These figures should not be added together without adjusting for reporting dates and definitions.
Microsoft’s new Hyderabad cloud region is already live, according to its September announcement, although its MW capacity was not disclosed.
A substantial pipeline, at different stages
Public announcements show expansion across established hubs and emerging locations such as Visakhapatnam and Jamnagar.
A groundbreaking provides stronger evidence of progress than an investment announcement. An MoU records a commitment but does not establish that the entire campus is under construction.
Large campuses also develop in phases. A 1 GW potential site may initially commission a much smaller facility. Google’s Visakhapatnam development involves AdaniConneX and Nxtra, illustrating why customer and partner announcements must not be counted separately.
JLL forecasts capacity rising from approximately 1.6 GW in mid-2026 to 6 GW by 2029. This indicates the possible scale of expansion, rather than guaranteed delivery.
Renewable buying is already growing
Meta has announced 837 MW of solar and wind projects with CleanMax and another 88 MW with Fourth Partner Energy. Google has supported a 150 MW solar project in Rajasthan, while Amazon announced three Indian wind projects totalling 379 MW in 2025.
Such agreements give renewable developers long-term customers beyond state distribution companies and improve revenue visibility.
However, corporate purchases can support wider operations. Apple’s Indian clean-energy initiatives also cover offices and retail activities; they should not be interpreted as evidence of a separately disclosed hyperscale campus.
What does this mean for electricity demand?
IT capacity measures power available to computing equipment. Total facility consumption is higher because cooling and other systems also require electricity. Actual demand depends on utilisation.
For illustration, 100 MW of IT capacity operating at 90% utilisation, with total site consumption equal to 1.4 times IT consumption, would use approximately 1.1 TWh annually. An additional 3 GW on the same assumptions would require around 33 TWh a year.
These are illustrative calculations, not demand forecasts. The government separately reports a CEA estimate of approximately 17 GW of data-centre power demand by 2031-32-a future requirement, not current IT capacity.
BigMint assessment
Data centres need electricity throughout the day and night. Buying enough renewable energy over a year does not automatically provide uninterrupted clean power.
Their expansion therefore supports demand for solar, wind, storage and dependable grid supply. Coal-based generation could meet part of the remaining requirement when renewable output is insufficient, but additional coal consumption cannot be calculated from campus announcements alone.
The decisive indicators are construction progress, customer commitments, power connections and commissioning schedules. India’s pipeline is substantial; its impact on energy markets will depend on how quickly that pipeline becomes operating demand.
