Skövde Energi and OneCo upgrade the electricity network in Skövde

The original station in Skövde, built in 1973, was in dire need of upgrading due to outdated equipment. To ensure continued reliable energy distribution in the area, OneCo installed new high-voltage components on the existing concrete foundations. At the same time, safety was improved by introducing more back-up systems to guarantee operation in the event of disruptions.

- "Everything went according to plan and we are very satisfied. The co-operation worked well and everyone was keen for the result to be good for us as a customer," says Henrik Larsson, who is responsible for electricity network operations at Skövde Energy.

OneCo’s switchgear experts were involved in the project, taking responsibility for both the installation and testing of the high-voltage circuit-breakers. Part of the modernisation of the switchyard involved a switch to carbon dioxide as the insulating gas in the new high-voltage circuit-breakers. Thorough circuit-breaker testing ensured that the circuit-breakers function optimally and can regulate the flow of electricity safely.

The project initially faced some challenges. These included delays in the delivery of the switches and difficulties in coordinating outages because the regional network owner had another project nearby at the same time.

- The date of the outages was changed a few times but OneCo was very flexible and made every effort to get the work done before our peak period," explains Henrik Larsson.

The new substation, which was the final stage in the modernisation of the station, was completed in autumn 2023. It will now help ensure a more reliable electricity supply in Skövde for many years to come.
