Electricity grid distributor Elering has put up Estonia's first designer electricty pylon mast, named "Soorebane" last week. The pylon is located at the intersection of the Ääsmäe-Haapsalu and Risti-Virtsu highways in western Estonia.

The designer mast is part of a corner mast of the Harku-Lihula-Sindi high-voltage line.

Ain Köster, Elering's communications manager, told ERR the pylon was erected last Tuesday and will be connected to the power supply at the end of August or the beginning of September (see picture below).

Köster added: "The masts are usually chosen or taken from a so-called catalog, but we had to do a lot of engineering work and see how to visualize the artist's point of view."

Köster added that the construction of the line started in Sindi and it is alread ycompleted up to Risti, a municipality in Lääne County, adding the whole line will be completed around New Year's Eve.

Köster said: "The builder does it section by section, the way it gets ahead and then it is energized section by section. The whole line is not energized at once."

Elering, in cooperation with the architects association, announced a design competition in March 2016 to find a suitable plan for the construction of one of the corner poles of the high-voltage line, as a designer pylon in the Kuistlema bog area.

A total of 18 entries were received for the first competition of its kind in Estonia. In addition to the ideas received within Estonia, competition entries were submitted by architects from Austria, Denmark and the U.K. The competition was won by Soorebane, and the architects are Sille Pihlak and Siim Tuksam, from Part OÜ.
