Russian utility JSC RusHydro has commissioned another unit at its Sayano-Shushenskaya hydroelectric plant, adding 640 MW to the project's installed capacity.
The unit is the fifth to be put into commercial operation at Sayano-Shushenskaya during a restoration effort that begun after the plant's turbine hall flooded in 2009.
JSC RusHydro (LSE: HYDR) said rehabilitation work on four additional hydro turbines continues.
"The turbines will be fitted with a more efficient process protection system, which will automatically shut down the unit in case of any inadmissible deviations from controlled parameters," a company release said.
Sayano-Shushenskaya will have a total installed capacity of 6,400 MW when work is complete, RusHydro said.
