GUWAHATI, July 9 � Two faults occurring at the Kahilipara sub-station and the Sarusajai sub-station of the Assam Power Distribution Company Ltd (APDCL) around 8 pm last evening, resulted in a power crisis in the city for about 20 hours till around 3:30 pm today.
APDCL sources told this newspaper that because of a fault occurring in the �Bus� connecting the Kahilipara sub-station transformer to the outgoing circuits, the �Current Transformer� (CT � a transformer used to measure the amount of current flowing in a circuit by sending a lower representative current to a measuring device such as a meter) of the Sarusajai sub-station was damaged.
It needs mention here that the Sarusajai sub-station supplies power to the Kahilipara sub-station and the latter supplies around 200 MW of power to the city. The city receives around 250 MW of power from Kahilipara sub-station and Jawahar Nagar sub-station, with the major portion of power coming from Kahilipara, sources said.
The Kahilipara �Bus� was restored around 3:26 pm today, while the replacement of the Sarusajai CT preceded it around 12-15 pm.
It is expected that there would not be any power supply shortfall in the city this night. The peak-load-hour power demand of the city is around 250 MW, while its off-peak-load-hour power demand is around 200 MW, sources said.
However, it is anticipated that there would be an overall shortfall of around 250 MW in power supply in the State during the peak-load-hour today. During the off-peak-load-hour today, there was a very little amount of shortfall in power supply in the State.
During the peak-load-hour today, the State received around 280 MW of power from its own generation stations, while it received around 800 MW of power from the Central sector generation stations.
These days, the total peak-load-hour power demand of the State is around 1350 MW, while its off-peak-load-hour power demand is around 1000 MW. While the peak-load-hour power availability of the State is expected to be around 1100 MW today, its off-peak-load-hour power availability was around 800 MW today, sources said.
