On 30 June 2010, turbine 4 was started without a load to dry its electrical coils, to test it and to prepare it for switching under load later in 2010.[52] It was fully restarted on 4 August 2010.
By July 2010 the replacement of turbine 3 was underway and should be completed in December 2010. The new turbine has better electrical and hydrodynamic characteristics and a 40-year working life.[53]
On 6 July 2011, a ship loaded with new parts for the turbines left Saint Petersburg.[54]
On 8 July 2011, turbines 3, 4 and 5 were working under full load and turbine 6 was in reserve.[55]
On 11 November 2014 the renovations and repairs were fully completed.
