Separation of the transmission network

The transmission network is a system of ultra-high voltage lines for transporting electricity over lengthy distances. The majority are operated at 220 or 380 kV. One of the core elements of the liberalisation of Switzerland's electricity market concerns the separation of the transmission network. Here, ownership and operation of the transmission network have to be separated from other activities such as distribution network operation and electricity production and trading. The aim is to secure the non-discriminatory use of the transmission network.

The separation of the transmission network was carried out in the following stages:

  1. Separation of accounting of network operation and ownership from the other activities.
  2. Legal separation of the transmission network, for example by outsourcing it to a separate subsidiary.
  3. Transfer of ownership to national network operator Swissgrid.

As of the beginning of 2013, most of the network components had in fact been duly transferred to Swissgrid.

ElCom has been monitoring the transfer process right from the start, and will continue to keep a close eye on developments relating to the transmission network within the scope of its duty to supervise the security of Switzerland's electricity supply.
