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.

Swissgrid is testing the use of augmented reality glasses for substation inspections in a pilot project with Rimon Technologies GmbH, an ETH spin-off. The initial results and feedback from employees and service providers are promising.

Thanks to the initiative by naturschutzlösungen and Pro Natura, a new habitat is being created for yellow-bellied toads — under Swissgrid extra-high-voltage masts, of all places.

At a technical level, Swissgrid is doing everything needed to maintain secure system operation. However, private-law agreements between transmission system operators are not an adequate substitute for an electricity agreement in the long term. Swissgrid is reaching the limits of possible solutions at a technical level.

The third part of the blog series on the topic of resilience in the transmission grid looks at the human factor. We explain how Swissgrid defines processes to minimise the risk of errors by every single employee as well as how we mitigate the effects of errors.

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. In the second part of this series, we turn our attention to the area of supply.

When it comes to Jamie Paik’s robots, size doesn’t matter. The miniature devices make the most of their abilities by working together. The researcher wants her work to inspire others, but she has also had to answer some critical questions.

How laser scanning data helps to ensure that trees under power lines are felled in time.

For the first time in the company’s history, Swissgrid has awarded a general contractor mandate for the construction of an extra-high-voltage line: the Vertiaz consortium has been commissioned to design and build the entire underground cable link between La Bâtiaz substation and Le Verney in Martigny, Valais.

Data science enables vast quantities of data to be processed, patterns and connections to be identified, and thus reliable forecasts to be made

Electricity is the lifeblood of our modern society; it drives us silently and invisibly. It always takes the path of least resistance; to make it tangible and depict it seems impossible. Not so for Nadieh Bremer.
