IBE was established in 1949 under the name of Hidroelektroprojekt with the view to design hydro power structures. It's largely owing to the merits of Mr. Valentin Tomše, its first Managing Director that the establishment of the Company happened by merging of the following groups:

  • the group of Projektni zavod Ljudske Republike Slovenije for hydro power plants with its headquarters in Ljubljana which has been implementing the Moste HPP design since 1946 and started with design engineering of the Medvode HPP,
  • the group of Brigada Drava, working in Maribor, which provided all main design documents for the Mariborski otok HPP and in 1948 started with design engineering of the Vuzenica HPP,
  • the group of Slovenija projekt from Ljubljana implementing design engineering of substations and overhead transmission lines, and
  • of certain individual experts who came from the disintegrated central design engineering bureau of the Ministry of Electric Power Industry in Belgrade.

The Memorandum of Association was issued by the Government of the LRS (the Public Republic of Slovenia) which assigned the Company to take a role of Design Engineer authorised for design engineering of electric power facilities in the Republic of Slovenia. In the first years of development the activities of the company extended very quickly to other spheres of power engineering, which led to the renaming of the company into Elektroprojekt.

In the 1960s, the company entered the markets of industry and infrastructure and changed its name to Inženirski biro Elektroprojekt where the present name of IBE came from. IBE played an important role in numerous investment projects and gave an important contribution to the technical knowledge and overall development of Slovenia. In this way, it gradually became and has been constantly consolidating its position as the leading consulting engineering company in Slovenia.

Great commitment and comprehensive know-how based on seventy years of practical experience have brought about strong company's values, fostering high quality services, personal responsibility, team work targeted at improved efficiency, transfer of knowledge and last, but not least, a commitment to a strong sense of ethics and the codes of conduct of consulting engineers’ associations.
