All of Karnataka, except Dakshina Kannada and Udupi districts, and most parts of coastal Rayalaseema and Telangana region in Andhra Pradesh went without power from 1250 hrs to 1430 hrs following a technical fault at the Vijayawada-Vijjeshwaram thermal station feeder.
The power breakdown disrupted rail traffic on the South Central railway for about two-and-half hours and normalcy was restored after eastern grid extended power, railway sources said.
Ramagundam and Raichur stations of National Thermal Power Corporation (NTPC) tripped on account of “under frequency conditions”, Karnataka Power Transmission Corporation director (transmission) S Shivamallu told PTI.
Sharavathi Generating Station and Nagjhari Power House were also shut down along with NTPC plants, a KPTCL release said adding supply from Varahi generating stations was extended to the former two and then the generation started.
Power supply was being restored in the affected areas and efforts were on to resume supply in all essential services, railway tractions and hospitals, a release from Andhra Pradesh chief minister’s office said.
Ramagundam and Raichur thermal power stations are expected to be restored by midnight on Wednesday, NTPC officials said. — PTI
