Viru-Nigula Wind Farm 110 kV substationTüükri village, Viru-Nigula, Lääne-Virumaa

In January 2007 Merko Ehitus finished construction works of the Viru-Nigula wind farm 110 kV substation, which included design, construction, installation, adjusting works and construction works of a control building. Construction works of the substation included installation of 3.1 km of 110 kV overhead power lines, construction of a control building and 110kV distribution board. For the first time in Estonia relay protection and automation means manufactured by an Austrian company, Sprecher, were used for building 0 110 kV substation. For Merko Ehitus, as the main contractor, it was the first project of high voltage substation. After experience in designing, constructing, adjusting and equipping such a “design-and-build contract” of a substation, Merko owns a qualified team that will be engaged in constructing substations in the future as well.
