PJSC RusHydro announced Dec. 23 that it had inaugurated the 140-MW Zelenchukskaya hydropower plant, calling it a hybrid facility because it combines conventional hydropower and pumped storage.
During the night, the hydropower units pump water up to the regulation pool. During the peak period, electricity will be generated. The facility has a working head of 220 to 230 meters and is equipped with two reversible hydropower units that were installed in the existing powerhouse of the Zelenchukskaya hydro plant. Average annual output from the new units is expected to be 162 GWh.
The facility is on the Kuban River in the Karachay-Cherkess Republic in the North Caucasus region in the south of Russia.
With this plant commissioning, the Republic can source up to 45% of its electricity needs through local production, RusHydro says.
Work on the project appears to have been delayed, as HydroWorld.com reported in 2011 that RusHydro expected the project to achieve its design capacity in 2013.
The original Zelenchukskaya project features two 80-MW turbines, one installed in 1999 and the other in 2002.
