Replacement of three Tallinn 110kV overhead lines with cable lines


Civil engineering

Energy supply

Concrete works


Description of work




Within the framework of the contract, the cable line will replace the 110-kV overhead line between Kadaka and Veskimetsa substations in Tallinn. The cable line will partially replace the 110-kV overhead lines between Harku and Veskimetsa and Harku and Kadaka substations. The total length of the cables to be installed is approximately 10 kilometers. The construction of new high-voltage cables will improve the security of supply in the Mustamäe and Haabersti districts and in the vicinity of Tallinn. As the existing overhead lines will be dismantled after the installation of new cables, the visual impact of overhead lines in Õismäe and Astangu areas on urban space will be reduced.

Both open and closed methods are used for cable installation. The underground cable is laid over the entire route to a depth of 1.5-6 meters. After the work is completed, the asphalt pavement of the carriageway and sidewalks will be restored, and thousands of square meters of greenery will be built.

The work is carried out by the consortium AS Merko Infra and Connecto Eesti AS.

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.
