Electricity is always flowing and the energy sector is always active – 24/7, 365 days a year. New grid projects, exciting facts about electricity, digitalisation, innovations, the environment – we regularly publish informative articles on a wide range of topics. Always up-to-date, always with our finger on the pulse. Welcome to our blog!
The assembly of the cable connection gantry for the La Bâtiaz – Le Verney underground link and the replacement of pylon 51 on the Chamoson – Romanel 380 kV overhead line are under way at the Verney construction site in Martigny. These two elements are essential for connecting the underground link to the Swiss extra-high-voltage grid. The underground cable link is scheduled to be commissioned in spring 2022.
In the new brochure “Substations and Transformers – Important Elements in the Transmission Grid”, we describe the role of switchgear and transformers in the transmission grid in simplified terms.
Cable laying for the underground link between La Bâtiaz and Le Verney in Martigny is currently under way. Delivery of the twelve cable reels has been taking place in stages since the beginning of December, as the cables need to be warmed up before being installed in the gallery. The underground cable link is scheduled to be commissioned at the end of March 2022.
Without interrupting the transmission of electricity
Since 5 November 2021, the electricity produced by the hydroelectric power plant in Fionnay in Valais has been transported via Swissgrid’s 220 kV Fionnay–Riddes overhead line.
In a three-part blog series, we explain how Swissgrid creates resilience in the transmission grid in the areas of installations, operation and supply as well as in relation to the human factor. The first part of this series is dedicated to installations and operation.
