Sweden, Stockholm: Linxon will upgrade an electrical substation for Svenska kraftnät, with ABB as their main supplier.
The order is worth around $65 M and consists of, among other things, two large digitally enabled ABB Ability Power Transformers (400 / 220 / 11 kV, 500 MVA) and the 400 kV GIS substation which will be used to upgrade and extend the electric transmission grid in the city of Stockholm.
The 400 kV GIS substation is located in the southern exit of the cable tunnel, close to Hammarby Sjöstad. It will connect the cables from Anneberg, the future substation Snösätra in Högdalen and also feed the existing 220 kV substation in Skanstull.
The equipment in the substation represents state-of-the-art technology to ensure grid reliability and sustainability. Along with the 400 kV GIS substation and two large digitally enabled ABB Ability Power Transformers (400 / 220 / 11 kV, 500 MVA), the supply consists of two 400 kV shunt reactors in addition to MicroSCADA Pro, a power automation and control system. All products are supplied by ABB, while Skanska, a project development and construction group, will be in charge of the civil works which are planned to start during autumn 2019. The energizing of the substation is planned for mid 2022.
