Nothing came out of the power-plant chimneys for many hours on Monday.
After the northern grid failure that morning, engineers at Guru Nanak Dev Thermal-Power Plant (GNDTPP) in Bathinda and Guru Hargobind Thermal Power Plant (GHTPP), Lehra Mohabbat, were able to revive only one of total six working units by afternoon and rest by late evening.
The Lehra Mohabbat plant has four units, and its unit 1 was running continuously since May 3 before tripping on Sunday night.
It resumed power supply at 1.30pm on Monday. Unit 2, producing power since May 2, and unit 3, on without break since January 18, were also fixed. Unit 4 was yet to cool down.
Before shutting, the unit had run for 126 days without interruption. Only two working units of the Bathinda plant resumed power supply.
The northern grid tripping not only caused massive losses to the state but also delayed the synchronisation of unit 3 of Bathinda's Guru Nanak Dev Thermal-Power plant, which was supposed to produce about 60- megawatt electricity for Punjab to help it tide over its power crisis.
