For Swissgrid, sustainability means being the backbone for a secure supply of electricity in Switzerland, both now and in the future.

The pretty purple blossom of the summer lilac, the yellow flowers of the ragwort or the large white flower clusters of the giant hogweed: these plants are beautiful to the eye and seem harmless at first glance. But they are in fact invasive neophytes that can pose a threat to the environment.

Swissgrid strives to be an innovative, diverse and inclusive company that all employees feel comfortable to work for. Its diversity and inclusion strategy is based on the principles of protecting personal integrity, non-discrimination, optimal working conditions and leadership culture.

The construction and maintenance of lines and substations can have a significant impact on biodiversity and measures are defined to protect it.

Swissgrid cooperates with universities to develop the new technologies and methods required to enable the efficient and secure transmission of energy.

For several years now, a fruitful partnership has been developing between Swissgrid and the start-up Gilytics, a spin-off from the ETH Zurich to meet a major challenge in the Swiss energy sector.

Even when there’s little wind, rainfall or sunshine – the demand for electricity will still have to be met after the energy transition. This can be achieved using a range of storage technologies that perform different functions within the energy system.

A large part of the extra-high-voltage grid operated by Swissgrid consists of overhead lines. Electricity pylons ensure the necessary stability and safety for power transmission. The grid comprises around 12,000 pylons and 6,700 kilometres of lines. As the regular monitoring of exposed infrastructure is very time-consuming, Swissgrid launched a feasibility study called «Pylonian» in 2021. The objective was to monitor selected electricity pylons around the clock using sensors based on Internet of Things technology.
