The Bratskaya HPP resumes normal operation; OJSC Irkutskenergo sets up a special commission to investigate the causes of the accident

On June 19, 2013 at 3.37 p.m. (Moscow time), a 220 kV voltage transformer broke down at the Bratskaya HPP, causing a minor spill of burning oil. As the protection system was activated, electrical equipment in smoke-filled areas and some of the power lines supplying electricity to the Bratsk Aluminum Smelter were disconnected.

On-call firefighters arrived at the site at 3.47 p.m. and started fighting ground fire. The fire was contained and extinguished promptly. By 3.58 p.m. the electrical equipment which had been disconnected was tested, and at 4.32 p.m. the previously disconnected 220 kV power lines of the Bratsk Aluminum Smelter were energized and the load started to be increased.

Power supply to all consumers has been restored; the Bratskaya HPP has resumed normal operation. A special commission set up by OJSC Irkutskenergo is investigating the causes of the accident.

Comment of Oleg Prichko, CEO of OJSC Irkutskenergo: “We would like to thank EMERCOM headquarters in the Irkutsk Region and emergency services in Bratsk for efficient and well-coordinated work. We would also like to thank the Company’s power engineers for their professionalism, as they immediately responded to the emergency.”
