Electricity's journey from the producer to the power socket is complex. The electrical energy passes long distances and through various stages before it is finally transformed to the 230 volts used by the consumer.

The transmission grid is the link between production and consumption. Therefore it plays a key role in the supply of electricity. Keeping the transmission system stable, safe and secure takes seamlessly operating infrastructure, continuous management of electricity flows and close cooperation with a wide variety of partners in Switzerland and Europe.
The heart of the transmission system, the Swissgrid grid control room, is located in Aarau. The operators monitor the grid around the clock and ensure that electricity is transported safely, securely and without interruption.
Are you interested in finding out more about the role of Swissgrid in the Swiss electricity supply system? Would you like to take a look over our operator's shoulders? We will be happy to show you Swissgrid's tasks and challenges and look forward to your visit to Aarau.
The final stage of the voltage increase to 380 kilovolts between Beznau and Birr includes a first for Swissgrid: at «Gäbihübel» in the Bözberg/Riniken region, Swissgrid is laying a 1.3 kilometre high-voltage cable underground. What are the opportunities and challenges of underground cabling and overhead lines in the extra-high-voltage grid? Swissgrid has set up a visitor centre in Bözberg to discuss this issue with the interested public.
Group tours can be booked from Monday to Friday, depending on availability (see available dates in the calendar below).
