After reconstruction capacity of the hydrounit has been extended to 41 МW.

When 72-hours load tests were successfully carried out the unit was put into warranty experimental-industrial operation. During starting-up and commissioning works capacity, vibrating characteristics, temperature mode and pressure under a turbine cover were checked. All test parameters correspond to norms and according to it Acceptance Certificate was signed.

On March 29, 2010 Hydrounit СВ 866/70-52М УХЛ4 of HPP Vartsyhe with capacity 23 MW was put into operation.
