Présentation :
When [Odensala substation] is ready, it will increase capacity in Uppsala and the Stockholm area and contribute to increased operational reliability through modern electrical facilities.
In addition to the station, a second Svenska kraftnät project, a 220 kV line relocation in Rätan, will increase the capacity of the network and improve reliability.
The modernization of three existing 130/10 kV stations for DSO Sundsvall Elnät AB will secure availability and increase capacity, ensuring a reliable and sustainable energy supply for the region.
The three new projects are extensive and will engage all the expertise we have within the business unit in Sundsvall, from engineers to technicians and assemblers, and create employment opportunities.
Odensala – reconstruction and new construction of one of the largest AC stations in Sweden
Svenska kraftnät’s existing station in Odensala is to be expanded and a new 400 kV station is to be built to enable the connection of planned power lines. It is an important investment to meet the increased need for electricity in the Uppsala and Stockholm area. The new station is the largest air-insulated switchgear that Svenska kraftnät has procured and is being built on an area of a total of 192,000 square meters, which corresponds to almost 27 football pitches.
Rätan – 220 kV line relocation
Svenska kraftnät upgrading the 220 kV station Rätan to increase the capacity and stability of the transmission network in the area. Omexom has previously carried out two renewal projects in the Rätan, and now receives continued trust from Svenska kraftnät to continue the strategically important upgrade. The project has started and will continue until the summer of 2025.
Sundsvall Elnät AB – modernization of three substations
In order to secure availability and increase capacity in the power grid in Sundsvall, Sundsvall Elnät AB is investing in three existing 130/10 kV stations. Omexom’s assignment consists of renewing the 130-kV switchgear in station M3 Södra Berget and expanding the 10-kV switchgear in stations M4 Gärdetjärn and M6 Granlo. The modernization will continue until the summer of 2026.
All three projects are part of Omexom’s commitment to supporting the energy transition and helping its customers to achieve their sustainability goals. Omexom in Sweden is proud to be a part of these important projects that will help to ensure a reliable and sustainable energy supply for Sweden.
