The commissioning of the modernised Avegno substation in the district of Vallemaggia in the Swiss canton of Ticino is a landmark achievement for TSCNET shareholder Swissgrid, the Swiss transmission system operator (TSO): “Since Swissgrid took over the Swiss transmission grid in 2013, it has been the first substation project to be fully implemented by the national grid company,” explains Maurice Dierick, Head of Grid at Swissgrid.
The Avegno substation is an important hub of the Swiss transmission network, both regionally and nationally. In addition, it connects the Verbano hydropower plant to the national extra-high voltage grid. Construction work at Avegno began in October 2016 and will be completed by the end of November with the dismantling of the old 220kV open air switchgear. Already in April 2018, the new gas-insulated switchgear (GIS) was connected to the grid. All in all, Swissgrid has invested CHF17m (almost €15m) in the modernisation of Avegno.
