Väo EJ 110 kV cable line with fiber-optic communication cable


Civil engineering

Energy supply

Concrete works


Description of work




The 110 kV cable line connects Tallinn Power Plant with Iru 110 kV substation. What rendered the project unique was the installation of cable by way of directional drilling – drilling was accomplished from a depth of 8 m below the River Pirita and Peterburi mnt.

On 1 July 2021, Merko Ehitus Eesti acquired a stake in Connecto Eesti, and the Merko electrical construction business line merged with Connecto. Acting jointly under the Connecto brand makes it possible for us to offer a significantly broader range of services – in addition to the design, construction and maintenance of low, medium and high voltage electricity networks, Connecto also operates in the field of telecommunications and gas networks.
