VEO has signed a turn-key contract with Vattenfall Eldistribution on a 45/12 kV substation in Jonsberg, close to Norrköping. The station is now under planning and will be equipped with VEO’s medium-voltage switchgear together with protection and control systems.

The new substation will feature modern indoor switchgear, ensuring power supply to Vattenfall Eldistribution’s customers and replacing the current obsolete substation and its outdoor switchgear. In addition to the new station, VEO’s scope of supply also entails the dismantling of the existing station. The total value of the contract is around 1.6 MEUR.

Planning for occupational safety during the winter

According to Andreas Martin, Sales Manager in VEO’s substation unit, the new substation is to be ready with final inspections and customer hand-over in November 2018. During the upcoming winter, VEO’s engineers will plan the execution of the project according to the customer’s needs and requirements.

“Although the technical solutions are similar to other Vattenfall projects of ours, work close to live high-voltage equipment in the existing substation requires careful planning,” says Martin. He continues: “The commissioning of the new station will the without any disruptions in the electricity distribution. The old station will be dismantled right after the new one is built, making the execution smooth for the end customer.”

New indoor substations replacing obsolete 45/12 kV outdoor switchgear stations are now built at a great pace in Sweden. The old outdoor switchyards have live high-voltage equipment that is not shielded from contact, creating a safety risk for anyone in the substation area. To improve safety, most 45/12 kV substations are carried out as the Jonsberg project, as modern indoor switchgear with arc discharge systems. The Jonsberg substation and all its technology will be enclosed by a 400-square metre concrete building.

"The old station will be dismantled right after the new one is built, making the execution smooth for the end customer.”

Creating jobs both in Finland and Sweden

According to VEO’s estimates, the Jonsberg project includes around 1 000 working days: for VEO and local subcontractors working at the site with civil and construction work, among other things. The civil engineering and the foundation work will commence in spring 2018.
