The fire reportedly started at 10:30 PM on Thursday.
Nine people are trapped inside a hydroelectric plant in Telangana after a fire broke out at its under tunnel power house late last night.
Nineteen people were on shift when the fire started around 10.30 PM at unit one of the under tunnel power house of the Srisailam hydroelectric plant, which is near Telangana's border with Andhra Pradesh. While 10 people managed to escape, nine others, including a division engineer, four assistant engineers, two junior plant attendants and two others from Amara Raja Batteries were trapped inside.
"As soon as the fire started, they tried to trip the units but that couldn't happen. So we isolated the 400 KV input and all units were tripped," Telangana Transco CMD D. Prabhakar Rao said.
According to initial reports, a short circuit at the underground hydroelectric power station situated at Srisailam dam's left bank is suspected to have led to the fire.
"The project unit operates at multiple levels. Those in the control room are said to have managed to come out. Others at lower levels couldn't come out because of the smoke. The current being switched off also hampered rescue and escape efforts," said one official.
A team of the National Disaster Response Force (NDRF) is currently trying to evacuate those trapped inside. They are being assisted by firemen. Teams from Singareni with experience in handling underground units are also present at the accident site.
Andhra Pradesh chief minister YS Jaganmohan Reddy has cancelled his visit to Srisailam project site where he was supposed to conduct Jala Harathi (puja). Meanwhile, Telangana chief minister KCR Rao's office said that he is continuously monitoring the operations at the accident site.
Energy minister Jagadish Reddy, minister Niranjan Reddy, CMD Prabhakar Rao, who reached the accident site at the night, are overseeing rescue efforts.
This is the first such accident at the plant, said Mr Rao. "Why it happened has to be investigated. How much damage has happened we will know only after the smoke goes away. Our priority right now is to rescue those trapped inside," he added.
