Power supply has been restored in several parts of Punjab and Haryana after it was disrupted on early Monday morning following collapse of the northern grid.
However, power utilities of both states said it will take some more time to begin generation in all their power plants.
"We have been able to restore about 3,000 MW of power in the state so far and we are increasing the load gradually," Haryana, special secretary (Power), Tarun Bajaj said.
Panipat's 250 MW unit has started generating power, while rest of its units will start generation soon.
Faridabad's gas-based power plant has also started working, which has a capacity of 430 MW, he said.
"All our 400 KV and 200 KV lines have been synchronised," and the hydel power units have also begun power generation, added Bajaj.
However, he said "it will still take another 2-3 hours to restore the entire power generation in the state as coal fired plants take time in generating power."
In case of Punjab, power supply to major cities like Ludhiana, Amritsar and Jalandhar has been restored, while efforts are being made to bring the power situation to normal.
In Chandigarh, power supply at most of the places has been restored with the supply of power from Bhakra Beas Management Board's power project.
