The agreement encompasses the construction of two 110 kV transformer fields (110/20/10 kV transformer units with a capacity of 2×20 MW), two 110 kV transmission lines field  and one spare field, one measuring field, construction of a control and power plant with a MV 20 kV facility, command-control-protection plant, implementation of SCAD system, telecommunication equipment, as well as TS integration into the electricity transmission network that will contribute to safe, stable and reliable supply of consumers of the Municipality of Sipovo. The substation is connected to the reconstructed 110 kV transmission line Mrkonjic Grad – Sipovo.

Elektroobnova, as the leader of the consortium, conducted the implementation of the entire Contract, according to the “Turnkey” principle, from the beginning of implementation to obtaining an operating license. Modern technical means and trained workforce were used, and state-of-the-art and reliable equipment was installed according to world standards.



The transmission and distribution networks consist of nodes and branches (lines). Distribution facilities are built in nodes. These plants can be with or without voltage transformation. Their basic role is to:

  1. enable connection of  lines of the same voltage level that are acquired in the node
  2. connect networks of different voltage levels through power transformers
  3. enable connection of sources (power plants) and consumers to the network.

Due to their purpose, distribution facilities can be divided into distribution plants and transformer stations. A distribution facility is any plant in which the lines of the same voltage level are acquired and its purpose is to provide a distribution of electrical energy on connected lines. The transformer station transforms the electrical energy from one voltage level to another, and thus networks of different voltage levels are connected.

Considering the importance of transformer stations and distribution stations in the electric power industry, Elektroobnova with its team of professional personnel and with the latest equipment and tools, is able to respond to all  requirements and questions in the shortest possible time with the maximum efficiency. We provide complete services for all stages of construction for transformer stations and distribution plants of all voltage levels:

  • We offer suggestions and conceptual solutions
  • We offer the most optimal design solutions
  • On behalf of the investor, we obtain all other neccessary documents for the purpose of obtaining a building permit
  • We provide services for the construction of new facilities, reconstruction and modernization of existing ones
  • We offer testing, commissioning and assistance services for obtaining use permit
