Employees of the Ladoga HPPs Cascade of TGC-1 took part in a training on liquidation of power grid equipment failures


On 17 April, a joint emergency training of TGC-1, the Leningrad RED branch of AD SO UES, PJSC Lenenergo and JSC RZhD (Russian Railways) was organised to develop steps to be taken by the personnel of these enterprises in order to liquidate malfunctions in power grid equipment.

According to the story, the operating emergency control system and electric protection systems in the operational zones of the Karelian RED and Leningrad RED branches of AD SO UES have caused disruptions in 110 and 330 kV lines, as well as in hydroelectric generators at the Nizhne-Svirskaya, Putkinskaya and Krivoporozhskaya hydroelectric power plants of TGC-1.

On behalf of TGC-1, the emergency team of the Ladoga HPPs Cascade participated in the training. Those actions were conducted under the leadership of the Leningrad RED dispatch operator taking into account the flood and ensuring the safe use of hydraulic facilities.

During the training, the possibility of allocating the Verkhne-Svirskaya HPP to work for Petrozavodsk in a "non-standard" format, i.e. with a 110 kW line, was demonstrated.

After the PJSC Lenenergo experts found the damaged part on the power transmission line and fixed the consequences of the breakdown, the emergency personnel of the hydroelectric power plants put the facility in operation and increased the load to the initial level on a signal of the Leningrad RED.

“As a result of the training, our employees and experts from related electric power companies worked through joint actions. For the north-western electric system, in such emergency situations, it is particularly important to demonstrate expertise and coordination in order to prevent an interruption of the electric current between the Leningrad Oblast and the Republic of Karelia,” said Dmitry Vidyakin, Director of the Ladoga HPPs Cascade of TGC-1.


TGC-1 is the leading producer of electricity and heat in the North-West of Russia. It comprises 53 power plants in four constituent entities of the Russian Federation: St. Petersburg, the Republic of Karelia, and Leningrad and Murmansk Oblasts.
