At the time, repairs were estimated to take up to four years.
 Over 2,000 people were involved in the rescue work and liquidation of the consequences after the disaster.
 According to Russian Energy Minister Sergei Shmatko, the rebuilding of the engine room alone was estimated to cost 40 billion rubles (€880 million, US$1.3 billion).
Russia's Sberbank agreed to lend 20 billion rubles (€440 million, US$630 million) for the repair works.
 RusHydro also is negotiating a loan with the European Bank for Reconstruction and Development.

According to RusHydro, turbines 4, 5, and 6 will probably be repaired.
Turbines 7 and 9 were too damaged and are being disassembled.
 The machinery hall, heating system, electricity supply, and sewage tunnels were under repair.
 As the spillway works all the time, several methods of preventing the dam from icing were also under consideration.
 The machinery hall and its heating system is also underwent repairs.
 The repair work was performed continuously, 24 hours a day.

For movement time of the spillway well crane КБГС-1000 the spillway was reduced to 1,105 m³/s (39,000 cu ft/s).

Near the end of 2009, there was an ongoing battle with icing.
All 11 spillway gates were opened to 0.5 from the first step.
70 heat guns with a total output of 1,500 kW were provisionally installed under part of the recovered machinery hall roof to prevent it from icing.
Chemical (MgCl₂ 6 H₂O) and mechanical methods are also used against icing.

By 27 December 2009, there were on-going or prepared dismantling of turbines 1, 2, 3, 4, 7, 8, 9, and 10.
 Only turbines 5 and 6 were to be repaired in situ.
The other turbines were to be replaced, repaired in the factory and/or modernized.

Turbine 6 was restarted on 24 February 2010.
Russian President Vladimir Putin personally switched turbine 6 to the load.
Turbine 5 was brought under load on 22 March.

On 14 April 2010, the process of dismantling turbine 2 and the infrastructure surrounding it was finished.
By the year 2014 all turbines in the plant will be replaced with new ones.

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.
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.

On 6 July 2011, a ship loaded with new parts for the turbines left Saint Petersburg.

On 8 July 2011, turbines 3, 4 and 5 were working under full load and turbine 6 was in reserve.

On 11 November 2014 the renovations and repairs were fully completed.
