What caused power demand to peak in December?
Power demand typically rises during December and January as colder temperatures increase the use of heating appliances. This year, a sharp cold wave across Jammu & Kashmir, Himachal Pradesh, Haryana, Punjab, Rajasthan, Delhi and Madhya Pradesh pushed up electricity consumption, with temperatures dropping to as low as 4 degrees Celsius in some areas. Delhi recorded its coldest December day in six years on 31 December 2025.
