Reconstruction of Mustla 35(110)/15kV substation


Civil engineering

Energy supply

Concrete works


Description of work




A new 35/15 kV substation was designed and built on the turnkey principle with the prospect of a transition to 110 kV supply voltage. The new constructed substation building was installed with a 16-section 15 kV distribution device and earth current compensation equipment. In addition, the existing access road was reconstructed, and the existing old substation was disassembled at the end of the works.

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.
