Swissgrid

Swissgrid was established in January 2005 by Switzerland’s main electricity grid companies as part of the liberalisation of the electricity market. From 15 December 2006 Swissgrid coordinated Switzerland's transmission grid (380/220 kV), comprised up to that point of eight control areas. With the changeover on the night of 31 December 2008 to 1 January 2009 from eight control areas to one zone covering the whole of Switzerland, Swissgrid took over the operation of the entire 6,700-kilometre extra high-voltage grid.

When the transfer was entered in the commercial register on 3 January 2013, Swissgrid became the new owner of the Swiss transmission grid. Swiss transmission system operator Swissgrid has since been responsible not only for the operation of the transmission grid but also for its maintenance, renewal and expansion. The statutory requirement was thus met for the electricity companies to have completed the transfer of the transmission grid to Swissgrid by 1 January 2013 at the latest.
