Who we are?

What we do?

1

ELES – National Transmission System Operater in Slovenia

o Safe and reliable power system operation and power supply

o Development, construction and maintenance of HV grid

o We connect all relevant grid users

ELES – National Transmission System Operater in Slovenia

o We ensure safe, reliable and undisturbed transmission of

electric power in Slovenia and across its borders 24/7
