Recent intermittent and widespread rains in Chennai have brought notable relief to the city’s energy landscape, resulting in a substantial 20% reduction in peak power demand. Last Thursday, the demand dropped to 3,654 MW, primarily due to decreased usage of air conditioners as temperatures cooled.The city’s temperatures were recorded at a moderate 29.3 degrees Celsius on May 16, significantly lower than the typical 37.4 degrees Celsius for this time of year. This cooling trend has contributed to the reduced power consumption.
A senior official from TANGEDCO noted that the extensive rainfall has effectively curbed the city’s power demand, which had reached a peak of 4,590 MW earlier in May. Throughout the month, the demand consistently surpassed 4,000 MW, with the exceptions of May 12 (3,872 MW), May 15 (3,955 MW), and May 16 (3,645 MW).
Chennai’s overall energy consumption also saw a notable decline, falling to 82.26 million units from the record high of 97.43 million units observed on May 3. Over the past ten days, Tamil Nadu’s power demand has eased due to widespread rainfall across the state. The peak power demand on Thursday dropped to 16,480 MW from an all-time high of 20,830 MW reported on May 2, marking a significant reduction of 4,350 MW or 20%. Similarly, the state’s daily energy consumption decreased to 368 million units on Thursday, compared to a record consumption of 454.32 million units.
“The state experienced a sharp surge in power demand during April and May due to high temperatures,” explained a TANGEDCO official. “However, the recent rainfall has led to a significant decrease in air conditioner usage in homes, thereby contributing significantly to the overall decline in power demand.”
This shift underscores the impact of weather patterns on energy consumption and highlights the role of natural cooling in reducing electricity usage. The decrease in power demand is a welcome relief for the state, easing the strain on the electricity grid and providing a respite from the high consumption levels seen earlier in the month.
As Chennai and Tamil Nadu continue to experience intermittent rains, the trend of reduced power demand is expected to persist, contributing to more stable and manageable energy consumption patterns across the region.
