Azerbaijan suffered from power outage caused by accident at the Mingachevir HES

On the night of July 2 to July 3  the power transformer at the Mingachevir hydroelectric power station went out of service because of extremely hot weather. The Mingachevir HES supplies electricity to all Azerbaijan. So, the accident with the tranformer causes blackouts all over the country. This was reported by the Ministry of Energy of Azerbaijan.

“The main cause of the accident on the night of July 2 to July 3  disconnection at the main tie-station in Mingachevir”, reported the Ministry, while adding that on June 2 the outdoor temperature was above 40 °C. As of July 3 all of the 8 hydroturbines were put on hold.

By early morning of July 3 the power supply to Baku was fully restored, and partial supply of electricity to other regions of the country resumed. In order to overcome shortages in power supply, the country imported power from Russia and Georgia.

The Mingachevir HES was commissioned in 1954. A year later, they put into operation the Varvarinsk HEPS located 14 kilometer down the Kura river. Together these two HESs form the  Mingachevir cascade of hydroelectric stations. The output of the Mingachevir HES after the reconstruction in 2018 was increased from 284MW to 424MW.
