India’s data-centre capacity could expand from less than 2 gigawatts (GW) today to 24–26 GW, according to Central Electricity Authority (CEA) Chairperson Ghanshyam Prasad. He said the increase would still represent a limited share of India’s total electricity demand and that the expected growth has already been included in national demand forecasts and generation-resource planning.

What the CEA forecast means

Prasad made the assessment on 15 October 2026, in comments reported by The Economic Times/ANI. His comparison is between the data-centre sector’s present capacity—“hardly less than 2 gigawatt”—and a possible future level of 24–26 GW. He added that capacity could go somewhat higher.

That is a very large increase for one infrastructure sector, but it should not be read as a claim that data centres will consume 24–26% of India’s electricity. A gigawatt figure describes power capacity associated with data-centre facilities; the national-demand share depends on how intensively that capacity operates, its utilization profile, efficiency, backup systems and the size of India’s overall electricity system.

The CEA chairperson did not publish a numerical percentage for data centres’ share of national electricity demand. The supported conclusion is therefore that their share is expected to remain limited, not that it has been measured at a specific percentage.

Why a 24–26 GW sector can still have a limited national share

Capacity is not the same as annual consumption

Installed or usable capacity is the maximum electrical load infrastructure can support at a point in time. Electricity demand is measured over time and varies by hour, season and operating schedule. A facility may have high connected capacity but operate below that level for substantial periods, while India’s total demand includes households, industry, transport, agriculture, commerce and public services across the country.

Location matters to the grid

Data centres tend to cluster near fibre routes, cloud-market hubs, reliable substations and major cities. A concentrated 24–26 GW build-out could therefore create significant requirements on particular transmission corridors, substations and distribution networks even if its percentage of national demand remains limited. National averages do not remove the need to reinforce local grids.

Reliability loads are part of the design

Data-centre operators require continuous power and commonly engineer redundancy through multiple feeds, UPS systems and backup generation. Those arrangements affect how much generation, reserve capacity and fuel or storage capability the wider system must make available. The CEA’s statement focuses on ensuring that the country does not fall short of capacity when consumers need it, rather than treating the sector’s average energy share as the only planning metric.

CEA says the growth is already in power planning

Prasad said the expected data-centre expansion has been factored into future electricity-demand projections and that generation resources are being planned accordingly. In his words:

“Right now the data center is hardly less than 2 gigawatt. Even if it goes to 24 to 26 what has been said today and maybe it might go slightly higher as well. Still, as a percentage of the overall demand it is not going to be much…even if it happens for example, we have already factored this in our future projections and we are planning our resources to be built accordingly.”

He also stated: “What we are only concentrating is we should not at any point of time run short of capacity in the country so that we are not able to meet the demands of the consumer.”

Those remarks describe a planning assessment, not a guaranteed construction schedule. Forecasts can change as projects are announced, delayed, redesigned or cancelled, and as computing demand, efficiency and power-procurement models evolve.

What must be ready if the build-out occurs

Generation additions

India would need enough dependable generation to serve the combined load of data centres and other consumers during peaks. The CEA’s assurance that the sector is included in projections means planners are accounting for it while deciding the scale and timing of new resources.

Transmission and connection capacity

New campuses require timely transmission links, substations and high-capacity connections. A national supply surplus would not by itself prevent a connection bottleneck in a fast-growing data-centre cluster.

Reliability and reserves

Because digital services can be disrupted by even short outages, planning must cover operating reserves, restoration capability and the performance of backup arrangements. The relevant test is whether the system can meet demand at the required hour and location, not simply whether annual energy production is sufficient.

Renewable integration

The wider planning context includes a target of about 800 GW of renewable-energy capacity by 2035–36. Reaching that level while serving firm, round-the-clock loads requires transmission expansion, forecasting, storage or other flexibility, and complementary dependable resources. Renewable capacity totals alone do not specify how much power is available during every data-centre peak.

How this fits India’s electricity baseline

India recorded peak power demand of 242.49 GW in financial year 2025–26, according to a 2026 Press Information Bureau update. The same government context put installed non-fossil capacity at 256.09 GW, more than 51% of total installed capacity. These are system-wide reference points, not measurements of data-centre consumption.

Comparing the figures requires care: peak demand is an observed maximum load, while installed capacity is the nameplate capability of generation assets; data-centre capacity is a sector-specific infrastructure measure. They answer different questions and should not be added or divided without a defined operating assumption.

What to watch as projects advance

  • Whether announced campuses receive confirmed grid connections and construction timelines.
  • Which states and metropolitan regions absorb the largest loads, and whether transmission projects keep pace.
  • How CEA demand forecasts are revised as actual data-centre utilization becomes visible.
  • Whether new renewable capacity is paired with storage, flexible generation and transmission that can support continuous loads.
  • Any future CEA or government publication that quantifies data centres’ national electricity share instead of describing it only as limited.

Bottom line for electricity users

India may see a more than tenfold increase in data-centre capacity, from below 2 GW to roughly 24–26 GW or potentially higher. CEA’s position is that this growth will remain a limited portion of total national electricity demand and is already embedded in forward planning. The practical challenge is execution: building generation, transmission, reserves and renewable-integration capability early enough to serve concentrated, round-the-clock facilities without reducing reliability for other consumers.
