About the company

The ELES Company ensures the safe, reliable and uninterrupted transmission of electricity. ELES is the guardian of Slovenia’s electric power transmission system, which is closely connected to the transmission networks of neighbouring countries and integrated into the European energy system.

Our responsibility is that electricity is always at hand, ensuring the consumers can meet their needs and wishes at any time.

The ELES Group consists of the controlling company ELES, d.o.o., and the subsidiary companies TALUM, d.d., Stelkom, d.o.o., and Operato d.o.o. The TALUM Company from Kidričevo produces primary aluminium and premium-quality aluminium products. The Stelkom Company from Trzin enables all Slovenian and international telecommunication operators a high availability and reliability of communication services and the use of advanced technologies. Operato offers smart solutions for power system operators. SUMO dynamically calculates the thermal ratings of power lines and transformers based on atmospheric conditions, thus optimizing the transmission capacities and improving operation security.

Over 550 employees, experts in various fields, carry out their tasks in a responsible way. By using the knowledge and available modern technologies, they take care of the safe and reliable management, development, construction and maintenance of the high-voltage electric power transmission network.

They also deal with failures in the transmission network. In all kinds of weather, they do outreach work to re-establish an uninterrupted electricity transmission in the shortest possible time.

In 2014 we celebrated 90 years of the transmission network - 90 years of connectedness with people. It all started with the pioneers of electric power transmission in Laško and grew with the hands, hopes and knowledge of each and every employee.

Today, ELES’s network is a part of a modern electric power network and it also works towards the development of smart networks.
