Network evolution

The key evolution trends for grid facilities of the Company are:

  1. Connection of new consumers to facilitate Urals economy and increase transmission volumes.
  2. Construction of grid facilities to liquidate capacity deficit zones and ensure reliable and faultless operations of the grid system.
  3. Shaping of united grid area.

Growth of the Company’s asset base will facilitate federal programs, national projects, regional evolution programs and plans. Asset development is based on the grid evolution schemes in our service area prepared under Government Decree #823 dd. 17.10.2009 taking into account evolution plans of all system participants and regional load forecasts.

During the reported period regional authorities prepared and approved evolution scheme and program for the Sverdlovsk regional grids for 2014-2018 and up to 2023 (Sverdlovsk Government Decree #540-PP dd. 30.04.2013), evolution scheme and program for the Chelyabinsk regional grids for 2013 – 2018 (Chelyabinsk Regulator Decree #13/3 dd. April 30, 2013). But the Perm regional authorities have not yet prepared the documents for the Perm regional grids.

Today there are several 110-220 kV deficit zones in the Perm region (Perm-Zakamsk and Berezniki-Solikamsk load nodes), in the Sverdlovsk region (Ekaterinburg, Krasnoufimsk and Polevskoy load nodes) and in the Chelyabinsk region (Chelyabinsk, Chebarkul-Miass and Zlatoust-Kropachevo load nodes). To lift restrictions in the nodes as well as to increase reliability of supply and ensure connection possibilities for new consumers our investment program covers the following facilities:

Facility name Rationale
Reconstruction of 110/6 kV Severnaya substation (substitution of 2х16MVA transformers for 2х25MVA ones) Reduced number of shut-in main substations, no restrictions for new connections.
Construction of 110/10 kV Kochkino substation (2*16 MVA and 110 kV double-circuit line to Kochkino substation) Energy supply of a juice-producing plant (Sanfrit-Trade, ООО), facilitation of logistics and residential construction in the Perm district.
Reconstruction of 110 kV NTGRES-Viya aerial line Life cycle of the line exceeds standard operation time, the line is highly deteriorated and cannot be repaired.
Reconstruction of 110/35 kV Serov substation Replacement of obsolete equipment, non-threatening maintenance works on the substation, increased reliability of supply.
Reconstruction of 110 kV Zlatoust – Taganai #3 aerial line, 35 kV Urzhumka (tyaga) – Zlatoust (tyaga) aerial line Increased reliability of supply in Zlatoust-Kropachevo load node
Construction of 110 kV ChGRES-Massivnaya cable line, 110 kV ChGRES-Sportivnaya cable line Construction of an alternative power source for consumers in Central Chelyabinsk

In 2010 the Governments of the Perm, Sverdlovsk and Chelyabinsk regions and IDGC of Urals have signed agreements on social and economic cooperation. The agreements focused on cooperation in social, economic and ecological issues regarding regional strategic development as well as provision of facilities for efficient operations of the Company and its increased role in local development. Key points of contact are provision of stable social and economic regional development, preparation and implementation of perspective energy sector development schemes and programs, network infrastructure advances, creation of conditions and prerequisites for attracting investments to the energy sector, increase of supply reliability and quality.

Under 2011-2015 federal housing program local authorities implement individual housing projects for 2011-2015 in the Perm, Sverdlovsk and Chelyabinsk regions.

Projects Focus of the Project Implementation Plan
Construction of grids in Novyi microdistrict (Chelyabinsk) Connection of buildings under construction Completed in 2013
Construction of grids in Topolinaya Alleya microdistrict (Chelyabinsk) Connection of buildings under construction Completed in 2013

Besides, the Company closely cooperates with the Federal Housing Construction Promotion Fund. In 2013 we prepared information on connection options and infrastructure costs for would-be capital facilities on 33 land plots with overall area of 601.2 ha in the Sverdlovsk, Chelyabinsk and Perm regions.

Our R&D program is shaped by existing problems in grids and perspective innovative directions and includes creation of radically new technologies, methods and perfection of existing technologies. Proposals added to the program are as follows:

  • system-based grid evolution issues;
  • equipment for substations and structures and materials for power lines;
  • secondary substation equipment (protection, management, automation, metering and monitoring facilities);
  • reliability and security of grid operations and quality of transmission services;
  • increase of energy efficiency in grids.
Research ended in 2013 Research conducted during 2013 Would-be-implemented research
Engineering and implementation of geographic information system of IDGC of Urals, OAO Research of asymmetric operating modes of 380 V aerial lines to choose detection device parameters Engineering and implementation of autonomous supply systems to increase supply quality and reliability for remote consumers up to 100 kW

As a result of a GIS engineering and implementation research we produced a pilot GIS software and hardware package focusing on:

  1. Arrangement and storage of spatial data obtained during R&D and previous works.
  2. Model-set data processing enablement for a wide range of employees.
  3. Validation of spatial data technologies and elaboration of requirements for a corporate GIS.

Pilot production of the system was made in a Sverdlovenergo production unit determined as a testing field. The results may be used in production units and branches of the Company depending on financing.

The results are as follows: aerial photography (1:2000 scaled orthophotomaps, digital terrain model and stereomodels), development of standard technical documentation, generation of information on grid facilities of the Company, preparation of land-use documents, disclosure of line dimension deviations, laser scanning and production of a pilot GIS software and hardware package. Maximum effect from GIS software and hardware package and spatial data obtained from aerial photography was reached for connection of new consumers to low- and medium-voltage networks due to reduced number of visits to a connected facility.

Sphere of application for R&D results is interwoven with grid operability assurance. Implementation of R&D results helps alter technological processes on grid exploitation and evolution, connection and land plot management (including protective zones).

Developments from R&D activities in 2013 demanded no registration of patent rights or ownership. There were no requests regarding results of intellectual activities during 2013.

On December 27, 2013 the Company’s BoD approved the Standard Technical Policy for grids that determines key directions providing increased reliability and efficiency of grid sector operations in short- and mid-term perspective with proper industrial and ecological security based on innovative evolution principles providing nondiscriminatory access to grids for all market participants. The Technical Policy is focused on effective asset management, determination of optimum conditions and key technical trends for ensuring reliable and secure supply. To achieve the goal we solve a range of tasks:

  1. Improvement of grid technological management and application of modern methods for grid evolution planning;
  2. Overcoming of ageing of equipment by enhanced reconstruction and update works;
  3. Creation of conditions for application of new cutting-edge solutions and technologies in systems responsible for maintenance, administration, protection, information transmission, telecommunications and metering;
  4. Development of exploitation methods using modern means of diagnostics as well as technical, information and measuring systems;
  5. Improvement of standard technical and methodical documentation of the Company;
  6. Decrease of expenses on grid maintenance and repair;
  7. Application of highly-efficient energy-saving technologies.
