SydVästlänken (English: South–West Link) is a project for reinforcement of power grids in Southern Sweden and Oslo area in Norway. The project to be implemented by Swedish and Norwegian national grids operators Svenska kraftnät and Statnett.

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.

[2] 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 wind power generation.[3]

History

edit

The project was proposed in 2005 when Svenska kraftnät made decision to construct the Sydlänken (Southern Link), a reinforcement of the transmission grid between the Swedish provinces Närke and Skåne.[3] In January 2008, Svenska kraftnät and Statnett proposed to expand this project by integrating it with a new VSC HVDC connection between Norway and Sweden.[2] 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.[4]

Description

edit

The SydVästlänken will include sections:

The Barkeryd–Hurva and Barkeryd–Hallsberg sections form the southern branch of the project (former Sydlänken). The Barkeryd–Oslo section forms the western branch. Both branches will have capacity of 1,200 MW.[7] 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.[5]
