Next Stage of Upgrade Began at Verkhne-Tulomskaya HPP of TGC-1

TGC-1 decommissioned the hydroelectric generating unit No. 1 of the Verkhne-Tulomskaya HPP for subsequent dismantling and upgrade. Power engineers will upgrade its core equipment, as well as control and adjustment systems.

“Earlier, hydroelectric generating unit No. 4 was completely replaced as part of the sweeping upgrade of the hydroelectric power plant — it was commissioned on 01 April 2020. New equipment for hydroelectric generating unit No. 1 has already been delivered to the site, this will accelerate the installation of components and systems,” said Oleg Tyapinov, Chief Engineer of the Kola Branch of TGC-1.

The upgrade of the Verkhne-Tulomskaya HPP began in 2018.

Detailed project information is available on the TGC-1 website.
