First substation in Bosnia and Herzegovina completed

Upon completion of works on reconstruction and expansion of the 110 / 20kV Novi Grad in March 2017, Energomontaza justified the confidence of investor “Elektroprenos-Elektroprijenos BiH” a.d. Banja Luka.

The latest trend of the equipment of the most renowned manufacturers was installed in the substation. A completely new transmission line field and a transformer box along the reconstruction of the existing ones were made. Also, a new 110 / 20kV transformer of installation capacity of 20 MVA providing 100% reserve distribution network was built-in. The relay protection and control which enables the remote control of the substation were reconstructed.

In terms of construction a new transmission line field and a transformer box were made whilst the existing ones reconstructed, new cable channels and new transport routes were built, the existing fence replaced and operational command building was reconstructed.

This project provides power consumption stability and the ability to connect to the new TS 110kV transmission line DV Novi Grad - Kostajnica which would enable double-sided power supply of Novi Grad substation.

A particular challenge was that substation was off energized state, but with continuous power consumption.
