The installation of new electric power cables between the islands of Muhu and Saaremaa in the Väike väin has begun as part of a project costing more than €5.4 million ordered by the Estonian transmission system operator Elering.
Currently, the islands are powered by overhead lines on the dam on the Väike väin (Strait). The completion of a parallel sea cable will reduce the risk of the islands being cut off from power for an extended period in case of overhead line disruptions, Elering said.
It will also decrease the number of high voltage wires on the dam and the remaining overhead line can be put into order so it is more visible to birds.
The length of the new power cable from the island of Muhu to the new substation in Orissaare totals 6.7 kilometers, 4.7 kilometers of which will be submerged.
