TGC-1 Commences 2nd Phase of Service Lane Building at Verkhne-Svirskaya HPP

The Verkhne-Svirskaya HPP has started erecting bridge spans on the spillway dam, this being the final phase under the renovation program for the hydroelectric unit at the Verkhne-Svirskaya HPP, which began in May 2020.

The renovation program includes restoration of the bridge reinforcements together with underwater concreting and total replacement of the spans and the deck. The renovation is run in two phases: at the HPP site and on the spillway dam.

The work at the HPP is almost completed, with new trusses installed and the deck being covered with innovative Matacryl coating, which is resistant to dynamic loads and temperature drops, ten times more stronger and more durable than asphalt concrete. The specialists also proceed to installing new bridge spans on the spillway dam.

“Everything goes in line with the schedule and, as planned, will be completed by the end of 2021. In addition to the service lane renovation, the HPP will also have up-to-date local water treatment facilities to prevent water from running off the deck into the Svir River, which is critical for the local environment,” says Dmitry Vidyakin, Director of the Ladoga HPPs Cascade.
