On 28 April 2026, Tamil Nadu recorded its highest-ever power consumption of 470 MU. Solar generation that day was 57.34 MU, with daily output averaging 55–60 MU.
Peak demand crossed 21,000 MW in April. The state expects solar output to reach around 100 MU a day by next summer, and plans 10,000 MW of battery storage by 2030.
For businesses, rising demand and storage plans point toward more value in on-site solar and, over time, solar-plus-storage.
