Alstom Hydro France, Alstom Russia and the Russian United Energy-Construction (OEK) have signed an agreement with RusHydro to upgrade the Cascade of Kubansky hydropower plants in Russia.

The Kubansky Cascade hydropower plants comprise eight hydro power plants and one pumped storage power plant, with a total original capacity of over 460MW.

The modernisation programme is expected to increase the capacity by 10% to 20%.

Alstom will restore the electro and hydro mechanical equipment and install a new instrumentation and control system.

Alstom’s OEK partners will carry out the civil works.

A joint hydropower manufacturing facility to be built by RusHydro and Alstom in Ufa City, in the Republic of Bashkortostan, Russia, will provide a part of the equipment to rehabilitate the Cascade of Kubansky hydropower plants.

Completion of the modernisation project is expected to take about six to ten years.
