Solar surge powers Tamil Nadu to the top in southern grid performance

Chennai, May 2 Tamil Nadu has registered a strong jump in solar power evacuation, consolidating its position as the top-performing state in southern India.

Data compiled by the Central Electricity Authority shows that the state evacuated 2,186 million units (MU) of solar energy in March, reflecting a sharp year-on-year rise.

The latest figures mark an increase of 582.94 MU compared to the 1,603.08 MU recorded in March 2025, underscoring the rapid expansion of solar capacity and improvements in transmission efficiency.

Among southern states, Tamil Nadu led comfortably, with Karnataka reporting 1,806 MU and Andhra Pradesh 1,129 MU during the same period.

The growth in solar evacuation aligns with a steady rise in electricity demand driven by summer heat across the state.

Tamil Nadu’s peak demand crossed 21,000 MW in April, making it critical for the grid to integrate renewable energy efficiently while maintaining supply reliability.

With solar generation gaining momentum, it is increasingly supporting daytime consumption patterns and easing pressure on conventional power sources.

The evolving energy mix reflects a gradual shift towards cleaner power while ensuring stability through coordinated grid operations.

Officials indicate that the state’s power management systems are adapting to handle higher renewable integration, with solar generation contributing significantly to daily consumption needs.

On April 28, Tamil Nadu recorded its highest-ever power consumption at 470 MU. On the same day, solar generation stood at 57.34 MU, with average daily output currently ranging between 55 MU and 60 MU.

Looking ahead, the state expects a substantial increase in solar generation capacity, with projections suggesting daily output could reach 100 MU during the next summer season.

This anticipated growth is supported by multiple renewable energy projects currently under development across Tamil Nadu.

To ensure grid stability and optimize renewable energy usage, the state is placing increasing emphasis on Battery Energy Storage Systems (BESS).

These systems are expected to become a mandatory component in upcoming renewable and hybrid power projects, enabling efficient storage and dispatch of solar energy.

Tamil Nadu has set an ambitious target of developing BESS capacity of 10,000 MW by 2030. This move is aimed at strengthening grid resilience, reducing dependency on conventional power during peak hours, and ensuring uninterrupted electricity supply as renewable energy penetration continues to rise.
