India’s data-centre capacity could grow from less than 2 gigawatts (GW) now to 24–26 GW, according to Central Electricity Authority (CEA) Chairperson Ghanshyam Prasad. He said that even such a large sector-specific increase would represent a limited share of India’s overall electricity demand. The CEA says this expected growth is already included in its future demand projections and generation-resource planning.
What the CEA projection means
Prasad made the assessment on 15 October 2026, in remarks reported by The Economic Times/ANI. His comparison is between the data-centre sector’s current capacity—“hardly less than 2 gigawatt”—and a possible future level of 24–26 GW, with room for the total to go somewhat higher.
That would be a many-fold expansion in the sector’s capacity. It does not, however, mean data centres would consume 24–26% of India’s electricity. A gigawatt figure describing data-centre capacity is a sector capacity measure; the national-demand share depends on how intensively that capacity operates, its utilization profile, efficiency, backup arrangements and the size of India’s total electricity system over the same period.
The CEA chairperson did not publish a numerical percentage for data centres’ share of national electricity demand. The supported conclusion is therefore qualitative: even at 24–26 GW, the sector’s share of total demand is expected to remain limited.

How large is the increase?
| Measure | Figure | What it describes |
|---|---|---|
| Current data-centre capacity | Less than 2 GW | CEA chairperson’s description of the present sector baseline |
| Possible future data-centre capacity | 24–26 GW | Projection cited by Prasad; he allowed that it could go somewhat higher |
| India’s peak power demand | 242.49 GW | Peak demand recorded in financial year 2025–26, according to the Press Information Bureau |
| Installed non-fossil capacity | 256.09 GW | More than 51% of India’s total installed electricity capacity, according to the Press Information Bureau |
| Renewable-energy planning target | About 800 GW by 2035–36 | National capacity objective cited in the same planning context |
The table puts the figures in context, but they are not directly interchangeable. Peak demand is a system-wide instantaneous requirement, installed non-fossil capacity is the nameplate capacity of several technologies, and data-centre capacity is a sector measure. Comparing them without those qualifications can make the data-centre projection appear to be a direct forecast of electricity consumption when it is not.
Why a large sector can still have a limited national effect
National demand is much broader than one load category
India’s electricity demand includes homes, offices, factories, transport, agriculture, commercial buildings and public infrastructure across the country. As the national system expands, a rapidly growing data-centre segment can remain a limited percentage of the total even while requiring substantial new connections and dedicated supply in particular locations.
Capacity and consumption are different measures
A capacity figure indicates the scale of electrical and computing equipment that can be supported. Actual electricity use varies with utilization and operating conditions. The CEA’s statement addresses the sector’s expected contribution to overall demand, but it does not provide the operating assumptions or a numerical demand-share calculation.

Local concentration can matter more than the national average
Data centres tend to create large, concentrated loads where facilities and network infrastructure cluster. A limited national share can therefore coexist with difficult local questions: whether a distribution or transmission corridor has enough headroom, whether a connection can be delivered on schedule, and whether reliability reserves are available during system peaks. National percentages alone do not answer those location-specific questions.
Has the government planned enough generation?
Prasad said the expected data-centre expansion has already been factored into CEA’s future power-demand projections and that generation resources are being planned accordingly. In his words, the priority is that the country should not “at any point of time run short of capacity” and be unable to meet consumer demand.
That statement makes adequacy and timing the central policy issue. Planning must translate a demand forecast into resources that are available when needed, not merely add nameplate capacity. The relevant work includes:

- Generation additions: enough new supply to cover forecast demand and maintain an operating margin.
- Transmission readiness: high-voltage corridors and substations capable of delivering power to concentrated data-centre clusters.
- Reliability reserves: resources that can respond when demand rises unexpectedly or another plant or transmission element is unavailable.
- Renewable integration: grid, storage and balancing arrangements that allow a larger renewable fleet to serve load reliably.
- Connection timing: coordination between facility construction, network upgrades and generation commissioning so that a new campus does not arrive before its contracted supply path.
How the renewable target fits the data-centre build-out
The planning context includes an objective of about 800 GW of renewable-energy capacity by 2035–36. That target is not a dedicated data-centre supply promise, nor does it establish a specific percentage of data-centre electricity that will come from renewables. It indicates the broader direction of India’s power-resource planning as electricity demand grows and the generation mix changes.

Meeting that challenge can require a combination of firm generation, storage, transmission capacity, forecasting and demand-management arrangements. The CEA’s remarks establish that these requirements are being considered in aggregate planning; they do not publish project-by-project schedules or guarantees for every proposed facility.
What could change the outlook?
The 24–26 GW figure is a projection associated with dated remarks, not a fixed statutory ceiling. It may be revised as cloud-computing demand, artificial-intelligence workloads, construction schedules, technology efficiency, land and water availability, electricity prices, and policy conditions change. The national-demand share could also evolve if India’s total electricity consumption grows faster or slower than the data-centre sector.
For that reason, the most useful way to read the announcement is as a planning signal: data centres could become a major new class of concentrated load, but CEA does not currently quantify them as a large percentage of national demand. Future CEA planning documents would be needed to establish a precise percentage or to test whether the projection has changed.
Quick Recap
What readers should take away
- India’s data-centre capacity is described as less than 2 GW today and could reach 24–26 GW.
- The CEA chairperson expects the sector’s national electricity-demand share to remain limited, without giving a numerical percentage.
- CEA says this growth is already included in future demand forecasts and generation-resource planning.
- The main risk is not necessarily national demand volume, but delivering generation, transmission and reliability resources on time where large facilities connect.
- India’s wider planning backdrop includes 242.49 GW of peak demand in FY 2025–26, 256.09 GW of installed non-fossil capacity (over 51% of the total), and an approximately 800 GW renewable-energy target for 2035–36.
