ABB is to supply three 400 kV substations. These substations will enhance grid reliability and transmission efficiency.

The substations are scheduled to be commissioned in 2015. ABB’s project scope includes the design and supply of engineered packages for the high-voltage air-insulated switchgear substations.

The Sege 400 kV substation in southern Sweden will be replaced to improve grid reliability and supply quality power to the city of Malmö and to the Skåne region. In northern Sweden, two new 400 kV substations, Djuptjärn and Högnäs, will secure power supply to the city of Kalix. Högnäs, will also enable the integration of clean wind energy to the national grid in the Västerbotten region.
