Sursky hydroelectric complex has been protecting Penza from floods for 42 years and now it is time to repair its most important elements. The reconstruction of the complex has two stages, and it is to be carried out in 2021-2025. About 400 million rubles have already been allocated.
"During the reconstruction we will completely replace the lifting equipment of the main gates of the spillway structure and the concrete dam, we will equip these gates with an automatic control system and be able monitor them," explained Aleksey Varlamov, chief engineer.
Repair work was suspended for the high water period. Now the main task is to prevent the accumulation of excess water. Thanks to the autumn discharge, a free volume of 271 million cubic meters is now available. At the moment, 20-25 cubic meters per second are passed through the gates. Around mid-April, the situation may require raising this figure to 750.
"Our department has developed a plan for the accident-free passage of the spring flood. Almost all the points of this plan have been fulfilled: we have carried out a pre-flood survey of all hydraulic structures, and they are in working condition," said Maya Delodub, head of the hydraulic structure operation department of the Sursky hydroelectric complex.
Since 2014, the Sursky hydroelectric complex has been subject to increased safety requirements. In this regard, in 2023-2025, it is planned to create a second spillway here that will cost about 1 billion rubles.
