Above-normal temperatures have pushed Keralam’s peak-hour power demand 500–800 MW above typical September levels.
Thiruvananthapuram: Weak monsoon rains and above-normal temperatures across several parts of Kerala have pushed up electricity consumption, prompting the Kerala State Electricity Board (KSEB) to warn that partial power restrictions may be imposed during evening peak hours if power availability remains tight.

Several parts of the state recorded temperatures significantly above normal on Sunday, according to the latest data from the India Meteorological Department (IMD).

Heat drives up electricity consumption
The relatively high temperatures have contributed to a significant rise in electricity consumption in Kerala, KSEB said.
Peak-hour demand in the state has been 500 to 800 MW higher in recent days compared with the demand recorded during September in previous years.
The increase comes as the weak southwest monsoon keeps rainfall below normal in several areas, contributing to hotter conditions and greater use of cooling appliances.

Power availability remains tight
The pressure on Kerala's power supply is also linked to a broader increase in electricity demand across the country.
The rise in national demand has reduced the availability of electricity through power exchanges. According to the Grid Controller of India, a shortage of around 12,000 MW in electricity availability across the country has not yet been fully resolved.
KSEB has also reported an unexpected reduction in the availability of power from central generating stations.
Partial power restrictions possible
KSEB said it may have to resort to partial power restrictions if sufficient electricity cannot be procured through the power exchange and grid frequency falls.
If required, restrictions could be imposed during the evening peak period, between 6 pm and midnight.
The board said the measure would depend on power availability and the stability of the national grid.
