Reconstruction of the Avinurme 35kV substation


Civil engineering

Energy supply

Concrete works


Description of work




Within the framework of the agreement, the existing Avinurme regional distribution substation was reconstructed using the turnkey method. A new substation building was designed and built, where modern 35kV and 10kV distribution devices were installed with remote control and protection automation, as well as a ground connection compensation system was established. The existing external switchyard of the substation was demolished and disposed of. As a result of the construction work, electricity supply of around 1,000 industrial and private customers around Avinurme is improved.

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.
