2.4.1. Comprehensive Modernisation Program
A significant part of HPPs was commissioned in 1950-1960-s. By early 2000-s, there was a need for upgrade and replacement of the operating equipment. Due to the economic difficulties of those years, it wasn’t possible to replace obsolete and worn out equipment, and PJSC RusHydro could only execute periodic repairs and replacement of some components.
Since the mid 2000-s, PJSC RusHydro has conducted a selective replacement at several HPPs, but the rate of asset renewal did not allow to reverse the trend of HPPs’ ageing.
In December 2011, the RusHydro’s Board of Directors approved the Comprehensive Modernisation Program of generating facilities of PJSC RusHydro (CMP), for the period until 2025.
CMP is the unique project (in terms of its massive scale) of renewing operational assets in the energy sector. Within CMP, before 2025, RusHydro plans to will have replaced more than half of general equipment of the HPPs:
- 154 turbines (55 % of the total turbine fleet),
- 119 generators (42 % of the total generator fleet),
- 176 transformers (61 % of the total transformer fleet),
- 396 power circuit-breakers,
- around 8 thousand secondary control equipment items,
- more than 4 thousand auxiliary equipment,
- and to reconstruct hydraulic structures.
The CMP key goal is removal of all generating equipment with an expired safe operation life by 2025.
Apart from operational performance, modernization of the equipment improves its environmental performance and helps to reduce anthropogenic impact.
The program is delivered using innovative and energy efficient solutions (fibre optics, optical transformers, deposition of nanostructured materials, control systems based on microprocessors, systems of vibration monitoring, etc.).
MAIN RESULTS OF COMPREHENSIVE MODERNISATION PROGRAM IN 2016
For five years of the CMP implementation, 39 hydraulic turbines, 23 hydro generators, 41 transformers and more than 4,000 units and auxiliary electrical equipment were replaced. In addition, single components were replaced in a large amount of equipment.
In 2011-2016, the total capacity of the RusHydro’s HPPs increased by 267 MW.
It can be compared with the commissioning of a new HPP of medium size.
In 2016, the capacity of HPPs increased by 66.5 MW, seven hydraulic turbines, six hydro generators and eight transformers were replaced.
