Chennai Power Cut: Is Load Shedding Set To Return To The Tamil Nadu Capital?

After several months of relative respite, power cuts could be set to return to Chennai and other parts of Tamil Nadu as electricity demand continues to climb sharply across the state.

Since January, scheduled outages had become increasingly rare, a change widely attributed to the election period, during which authorities appeared keen to ensure uninterrupted supply. However, with the elections drawing to a close and vote counting scheduled for 4 May, there are growing indications that load shedding may once again be implemented, even though no official announcement has yet been made.

Recent data on electricity consumption suggests mounting pressure on the state's power infrastructure. On 28 April, Tamil Nadu recorded a new peak demand of 21,211 megawatts (MW), alongside a daily energy consumption of 470.674 million units (MU), according to a report in DT Next.

These figures mark a steady rise over recent weeks, surpassing the previous peak of 21,117 MW on 27 April and earlier highs earlier in the month.

The upward trend has been consistent throughout April. Peak demand rose from 20,974 MW on 16 April to 21,010 MW on 17 April, before continuing its climb to current record levels. Notably, this year's figures have already exceeded last year's maximum demand of 20,830 MW, recorded on 2 May 2024.

Daily energy consumption has followed a similar pattern. From 460.301 MU on 16 April, usage increased steadily, reaching 466.196 MU by 22 April and eventually peaking at 470.674 MU on 28 April. This surpasses the previous high of 454.32 MU recorded on 30 April last year.

Officials attribute the surge to a combination of seasonal and behavioural factors. Rising summer temperatures have led to heavier use of air conditioning, while late-night electricity consumption has increased during the ongoing Indian Premier League cricket season. Demand reportedly remains high even after 1 a.m., as residents continue to watch matches at home and in public venues.

The heatwave has been particularly intense in several districts, with temperatures exceeding normal levels by between 3.1°C and 5°C. Areas including Chennai, the Nilgiris, Dharmapuri, Kanniyakumari, Karur and Tiruchy have all recorded above-average temperatures in recent days.

Another emerging factor is the growing reliance on electric cooking appliances. Officials estimate that the increased use of induction stoves is adding between 300 MW and 350 MW to the daily load. This shift has been partly driven by constraints in the commercial LPG supply, prompting households and eateries to turn to electric alternatives.

Despite the surge in demand, authorities insist that the overall power situation remains under control, with sufficient arrangements in place to meet current requirements. However, with forecasts pointing to an even warmer May, electricity usage is expected to remain elevated. In this context, the reintroduction of power cuts in Chennai and across Tamil Nadu appears increasingly likely.
