Programme of modernization, technical rehabilitation and repairs
Comprehensive modernization programme
A significant number of powerful hydroelectric power plants were comissioned in the 1950s and 1960s, and by the early 2000s, there was a need to upgrade and replace existing equipment. Due to the economic difficulties of those years, it was not possible to replace obsolete and worned-down equipment; hence, PJSC RusHydro had to resort to periodic repairs and the replacement of separate units.
Since the middle of the 2000s, a number of stations of PJSC RusHydro had their equipment replaced, but the pace of asset renewal did not allow breaking the trend of aging HPP equipment as a whole.
In December 2011, the Board of Directors of the Company approved the Programme for the comprehensive modernization of generating facilities of PJSC RusHydro (PCM), designed for the period through 2025.
PCM is a unique project for the upgrade of generating facilities in the energy sector.
As part of the RusHydro Programme, it is planned to replace more than half of the main equipment at HPPs:
- 154 turbines (55% of the total number of turbines),
- 119 generators (42% of the total number of generators);
- 176 transformers (61% of the total number of transformers);
- 396 high voltage switches;
- ~ 8 thousand units of secondary switching equipment;
- more than 4,000 units of auxiliary equipment;
- in addition, it is planned to perform the reconstruction of hydraulic structures.

Technical Rehabilitation and Modernization Programme
The Technical Rehabilitation and Modernization Programme (further – TR&M programme) is based on a comprehensive modernization programme. It aims to maintain the proper operating condition of the equipment and to introduce new capacities into production, but, unlike PСM, it implies a replacement of the equipment with analogues with improved performance at RusHydro’s facilities. TR&M also suggests the extension of the standard operating life of the main generating equipment, reduction of production costs, and the increase of the efficiency of stations.
The programme of technical rehabilitation and modernisation of RAO ES East Subgroup is part of the investment programme of the Subgroup and is connected with the need to maintain the reliability of all technological facilities in the long term. Development and implementation of the programme takes place within the framework set by the technical policy of RusHydro Group.
As a result of RAO ES East Subgroup TR&M programme:
- 1.3 MW of new capacity commissioning;
- 17.2 km of heat lines commissioning;
- 189.82 km of overhead power lines.

In 2018, Rushydro Group planned the increase of installed capacity of PJSC RusHydro by 46.5 MW with help of technical rehabilitation of hydropower facilities:
- Changing hydroturbines - 7 pcs;
- Changing hydrogenerators - 5 pcs;
- Constructing gas-insulated 500 kV switchgear.
