Paldiski 6kV substation


Civil engineering

Energy supply

Concrete works


Description of work




A new 6 kV substation was built as a turnkey project. It supplies power to all of the city of Paldiski – 2,900 households. In the course of the work, a modern two-storey substation building with access routes was constructed, 6 kV gas insulated switchgear along with relay protection and control equipment were installed for improving environmental and electrical safety, and the power cables in the immediate vicinity of the substation were replaced. Merko also performed all the connections and configurations as well as disassembling the old substation. The substation for Paldiski area is a key electrical hub that handles 25 gigawatt-hours of electricity per year and supplies 81 smaller substations with power.

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.
