Elko started to perform electric design works in year 1999. As  the time progressed, we have grown and expanded, becoming a stable and trustworthy entity of the Latvian design market. At present, we are capable of executing projects of various complexity as well as electric design expertise (3rd group building design expertise, from 1kV up to 35kV, over 110kV ).

For execution of larger scale projects as “Estonia-Latvia third 330 kV interconnection”, we are cooperating with our local partners as well as our partners throughout Europe.
