380 kV Air-insulated switchgear (AIS) turnkey substation for TransnetBW GmbH, Germany

Linxon Germany has commenced work with the transmission system operator TransnetBW GmbH to upgrade the AIS substation in Beuren from 220kV to 380 kV, with completion scheduled for summer 2027. The project forms part of TransnetBW’s strategy to increase the capacity and reliability of the transmission network in Baden-Württemberg.

A brownfield investment, Linxon will provide the documents to obtain the required permit, and will then start construction work on the new 380 kV substation. Built in 1975, the existing 220 kV substation will remain operational and connected to the grid and will thereafter be dismantled and properly disposed off to ensure minimum outage.

The upgrade forms part of the German Grid Development Plan 2035 (Netzentwicklungsplan – NEP) which comprises the power grid modernisation and construction projects required to reinforce the German transmission grid over the next 15 years. The gradual increase of renewable energy share in the national energy mix necessitates an upgrade of the German grid to avoid bottlenecks in the transmission of power generated by off- and onshore windfarms in both the North and the South of the country.
