The peak power demand in the country touched a new historic high of 246 Gigawatts (Gw) around 3 pm on Wednesday afternoon.
As the country, especially the northern region, sizzled with heat waves, the power demand shot up.
It crossed the previous highest record of 242 Gw in September last year.
During the current year, May has witnessed several power demand records.
The country's peak power demand touched 239 Gw earlier this month, which was the highest for May earlier.
