Hagby 400 kV, 220 kV and 132 kV substations, Sweden

Linxon has been chosen by Swedish distribution system operator, Vattenfall Eldistribution, to deliver 400 kV, 220 kV and 132 kV substations in Hagby in northern Stockholm.

With commissioning planned for spring 2025, the new contract involves building a brownfield 132 kV station (comprising 8 bays and on the site of an old station to minimize increased footprint), the extension of a 400 kV substation with 2 bays and the demolition and replacement of a section of another 220 kV substation.

The Hagby substation refurbishment is part of an overall scheme to meet increased power supply demands by strengthening the transmission grid in the Stockholm region. In a time of heightened energy costs, the revamp is designed to both increase performance and decrease future maintenance costs, whilst ensuring minimal environmental impact.
