Aim

The southern part of the Nordic power grid between Sweden and Norway is relatively vulnerable for disruptions and quite often there are bottlenecks for power transmission. While in dry periods and low consumption periods problems are related to the West coast in Sweden, in periods with high hydroproduction and peak consumption problems are mainly related to the grid in Oslo area in Norway (the so-called Hasle-trappen). Western branch will not be built 2013-04-29 Swedish power grid, together with Statnett decided not to implement the project south-western branch of the link between backbone stations Barkeryd and Tveiten. New calculations show that the benefits have been reduced significantly compared with the original analyzes. Western branch will not be built 2013-04-29 The aim of SydVästlänken is to increase the transmission capacity and the robustness of the transmission system in this area. Increased capacity and flexibility of the transmission is particularly import for facilitation of the increased

connection between Norway and Sweden. Correspondingly, the project was renamed SydVästlänken. Technical issues continued to plague the construction, whose date of completion was postponed no less than 22 times before getting taken into commercial use in July 2021. Since then, numerous complaints about excessive noise from the facilities has been made, necessitating further measures to be taken.Elinstallatören (Swedish)

Both branches will have capacity of 1,200 MW. Construction of the southern branch to be start in 2012 with completion in 2017. Construction of the western branch to be start in 2013 and it is expected to be completed in 2017.
