"All of a sudden, there was heavy load and power frequency came down from the normal 49.9 per cent to 38.34 per cent leading to the collapse of the grid," Assam State Load Despatch Centre (ASLDC) Executive Engineer Ashok Saikia told PTI.
The collapse led to large-scale power cuts throughout the state but the situation is likely to improve with additional power inputs from Samaguri, Kathalguri and Namrup Thermal Power Plants which has so far been unaffected by the grid failure, he said.
"We have already restored power in some areas of Guwahati and in the state by offloading power in certain areas," Saikia added.
We hope to resolve the problem soon, the official said.
