The level of deterioration of IDGC of Centre electric grid facilities is 73.2% as at December 31, 2014, including:
Name of asset Deterioration level, %
Overhead lines, 0.4–110 kV 74.5
Cable lines, 0.4–110 kV 58.8
Transformer equipment, 3–110 kV 77.3
Switching devices, 3–110 kV 65.9
Substation equipment, 3–110 kV 72.4
Total deterioration of the organisational unit 73.2

The standard service life of facilities is taken into account when calculating the deterioration of assets:

  • 25 years for substations and cable lines;
  • 35 years for overhead power lines.

Asset Management System

The high level of the transmission facilities’ deterioration poses the need for improving asset management efficiency. In this regard, IDGC of Centre decided to create an Asset Management System (hereafter AMS) in 2006.

The company’s AMS development required elaboration of new approaches to the management of power grid companies’ production assets. The AMS has been fully implemented today.

The Asset Management System allows the Company to solve the following issues:

To reduce the costs of equipment maintenance and elimination of the consequences of its failures by means of:

  • alignment of priorities in making fund allocation decisions — primarily funds go to the equipment in the worst condition and having the greatest failure consequences;
  • justified determination of the optimal amount of funds ensuring equipment reliability for the company as a whole and of each business unit in particular

To ensure transparency and validity of decisions, efficient interaction between the departments, head office, shareholders and authorities:

  • each object of the repair and replacement programme has a rationale for its inclusion, which is simple and understandable not only for technical experts;
  • the possibility of repair and replacement programme options’ modelling with different amounts of funding allows us to prove the optimality of the decisions made

To improve the efficiency of asset management task planning and monitoring by means of:

  • ensuring that the company’s management and divisions have objective and sufficient information to establish economically sound equipment repair and replacement programmes;
  • changing the principles for repair and formation of replacement plans: instead of the approach where the request, formed at the bottom level, receives or fails to receive approval at the top level, a new principle has been implemented, where the task is set at the top level, and is to be carried out at the bottom level;
  • a possibility of automatic formation/revision of equipment repair and replacement programmes in case of changes in the business objectives and priorities

To increase the efficiency of task description, maintenance and repair services implementation using handheld mobile devices (Mobile solutions tools):

  • enhancement of input data reliability;
  • reduction of time spent on feeding information into the system to determine its technical condition;
  • reduction of the time spent on preparation of external examination, measurement and test reports;
  • provision of all the necessary documentation diagnostics;
  • measuring the progress and time of works
