ELES
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
