AI Data-Centre Boom Strains India’s Power Grid
Regional power committees are grappling with how AI data centres are changing electricity demand and grid costs, with PGCIL saying SCADA/EMS upgrades in the NERPC region will now cost about ₹688 crore, up from ₹521 crore

Why in News?
- Regional power committees are grappling with how AI data centres are changing electricity demand and grid costs.
- PGCIL told the NERPC that upgrading SCADA/EMS systems will now cost about ₹688 crore, up from ₹521 crore, because AI demand has raised hardware prices.

About the Issue
- One Nation, One Grid: India’s regional grids were unified under “One Nation, One Grid, One Frequency” in 2013. Load is managed by National, Regional and State Load Despatch Centres under the Electricity Act, 2003, with Grid-India running the national and regional centres.
- SCADA/EMS: These systems let load dispatch centres monitor and control the grid in real time.
- Deviation Settlement Mechanism (DSM): Framed by the CERC, it penalises deviation from scheduled power flows.
- AI data centres: They draw far more power than conventional ones, and their demand can swing with LLM usage and customer time zones.
- Ramping stress: These swings strain slow-ramping coal plants, which may face DSM penalties for deviations beyond their control.

Provisions
- Electricity Act, 2003: It sets out the roles of the CEA, CERC and load dispatch centres.
- CERC DSM Regulations, 2024: They govern penalties for deviations.
- Infrastructure status: Data centres received infrastructure status in 2022.
- Green Energy Open Access Rules, 2022: They let large consumers buy renewable power directly.

Significance
- Reliable power is essential to India’s goal of becoming a global data-centre hub.
- Studying demand early helps planners avoid reliability problems.
- Data-centre clusters can anchor renewable energy and storage investment.
- Clear grid-connection rules protect other consumers from sudden load swings.

⚠️
Challenges
Hardware Costs
Rising hardware costs burden grid operators.
Concentrated Demand
Demand is concentrated in a few cities, so State transmission utilities must expand quickly.
DSM Exposure
Ramping can expose generators to DSM penalties.
Cost Pass-Through
Upgrade costs recovered through transmission charges may pass on to all consumers.

Way Forward
Demand Forecasts
Grid-India and the CEA should prepare dedicated demand forecasts for data-centre clusters.
Ramping Norms
Regulators should set ramp-rate and scheduling norms for bulk consumers.
Clean Energy Co-location
Data centres should co-locate with renewable energy and storage and offer demand response.
Domestic Manufacturing
India should promote domestic manufacturing of grid control hardware.
Conclusion: AI data centres add modest national demand but create sharp local stresses on the grid. Forward planning, ramping norms and clean-energy co-location can turn this demand into an opportunity.
