Connecting MCF Group Estonia OÜ to Harku Substation


Civil engineering

Energy supply

Concrete works


Description of work




The substation expansion project includes the building of two new 110kV line compartments in the substation in connection with MCF Group Estonia OÜ joining the Harku substation. The work is carried out by the turnkey method, which means that in addition to the design and construction work, all the necessary equipment is supplied, installed, adjusted, tested and energized.

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.
