Tamil Nadu’s electricity consumption has dipped sharply over the past week, as overcast skies and cooler temperatures sweep across the state. The shift in weather has brought temporary relief to residents and eased pressure on the grid.

Weather Impact and Consumption Trends

Peak power demand fell to 17,001 MW on Tuesday, down from 18,853 MW recorded the previous week.
Daily energy usage dropped to 370 million units (MUs), compared to 415 MUs during the same period last year.
Chennai’s maximum temperature hovered around 31°C—4.5°C below the seasonal average—due to persistent cloud cover and intermittent rainfall.

Sectoral Effects

Residential consumption declined as households reduced use of air conditioners and cooling appliances.
Agricultural demand also fell, with widespread rainfall lowering the need for irrigation pump sets.
Appliance retailers reported a noticeable drop in sales of air conditioners and coolers, citing reduced customer interest.

Grid and Infrastructure Relief

The cooler climate has helped power managers conserve energy and reduce reliance on thermal stations.
Wind energy utilization has increased, especially in southern districts, improving grid efficiency and lowering fuel costs.

Outlook

Officials from TNPDCL expect the dip in demand to be temporary, with consumption likely to rebound once temperatures rise.
Meteorological forecasts suggest continued light to moderate rainfall across parts of the state, keeping demand subdued in the short term.
