The key activity and mission of the ELES Company is the safe and reliable operation of Slovenia’s electric power transmission system, which we provide 24/7 throughout the year.
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.
We believe that responsibility, engagement, knowledge, reliability, cooperation and determination are the key to success of each and everyone and of the ELES Company. By adhering to these values, the company can successfully fulfil its mission and implement its vision of being the leading company in the Slovene electric power system and becoming a key element in the energetic stability of the region featuring one of the most modern networks from the technological point of view.
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.
Responsibility is one of the key values of the ELES Company. Sustainable development is thus realised with responsibility to the owner, the Republic of Slovenia, and with achieving business excellence, environmental protection and responsibility to the social environment.
The construction of transmission lines influences the natural and social environment. We do our best to minimise this influence. ELES has an important partner in local communities and carries out various activities to contribute to a better quality of life for their citizens.
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.
The electric power transmission network cannot be operated by itself. It needs to be connected to the networks in the neighbouring countries and integrated into a wider electric power system. Therefore, the ELES Company closely cooperates with the neighbouring system operators and actively participates in many regional and international associations.
Only successful international cooperation can ensure the stable operation of the European electric power transmission system and the maintenance of the 50 Hz frequency.
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.
