    Since its establishment in 1989 as ET “EL– Stefan Stefanov” until now, the company EL EOOD has implemented multiple projects within the territory of the country – low and medium voltage cable lines, subfeeders, low, medium and high voltage overhead power lines.

    EL EOOD has concluded a framework agreement with "E.ON Bulgaria Grids" AD and implements energy projects from their the investment and maintenance programme and joins new users of "E.ON Bulgaria Grids" AD since 2006 -on the territory of the district of Ruse, since 2008- on the territory of the Districts of Ruse, Razgrad and Silistra, and since 2009 - on the territory of the Districts of Ruse, Razgrad, Silistra, Dobrich, Targovishte, Shumen and Varna.

    The company disposes of a large number if own transport vehicles and machinery, and uses them for mass excavations and all types of transport services.

    Some of the most significant sites EL EOOD has constructed in the last years in the field of power engineering – sites of "NEC" EAD and "ESO" EAD, high voltage 110ęV and up are as follow as:
