Tamil Nadu recently experienced its highest-ever electricity demand, reaching 20,974 MW, due to the intense summer heat leading to increased power consumption. The daily energy usage also peaked at 460 million units (MU), indicating significant strain on the grid during the prevailing hot weather. This surpasses the previous records of 20,830 MW and 454.320 MU, respectively.
The surge in electricity demand is a direct result of the rising temperatures in Tamil Nadu, with many areas recording temperatures 2–3 degrees Celsius above normal. Locations like Karur Paramathi saw a peak temperature of 41.2 degrees Celsius, while Erode and Madurai witnessed temperatures around 40 degrees Celsius, signaling widespread heat stress. Officials note a visible impact of the prolonged heatwave on the state’s electricity consumption patterns.
The state has been consistently crossing the 20,000 MW mark for peak load, indicating sustained high consumption rather than sporadic spikes. Despite solar power contributing to meeting daytime demand, the overall consumption remains high due to extended periods of elevated temperatures. A comparison with the previous year reveals a significant increase in demand, with current usage frequently exceeding 400 MU and remaining above 420 MU on multiple days.
The trend of escalating demand and consumption levels is expected to continue as the hot and humid conditions persist in Tamil Nadu. The grid is under pressure primarily due to the heightened use of cooling devices and the sustained high temperatures witnessed across the state.
