ELES d.o.o.

With our RELIABLE MANAGEMENT OF THE ELECTRICITY SYSTEM, we ensure stable and efficient development of the Company and the transfer to a carbon-free Slovenia and region.


The Slovenian electricity system is managed and overseen from a modern and internationally established centre. We maintain a balance between electricity production and consumption, and provide system services.


By maintaining, building and modernising the electricity grid infrastructure, we meet the growing demand for electricity and ensure its safe and efficient transmission. Our on-site maintenance crew provides an optimal response to the physical events and maximises the reliability of ELES infrastructure.

Strategic innovations

We demonstrate our ongoing commitment to innovation by participating in major research, development and pilot projects financed by ELES, grants from EU, and other funds. In doing so, we cooperate with international and domestic stakeholders, helping develop the electricity sector in Slovenia and Europe.

Future orientation

With sustainable, systematic and professionally organised efforts in developing innovative projects that are integrated into all of our strategic activities, we are developing the transmission network of the future. In addition, we participate in many international projects, seeking solutions to the most challenging issues regarding the future of electricity and its transmission between producers and consumers. We are strengthening cross-sectorintegration and looking for joint solutions for the effective transition to a carbon-free society.
