These concessions shall expire on 31 December 2032. In accordance with the Federal Law on the Use of Hydropower, Salanfe SA has informed the concession-granting municipalities of its intention to request the renewal of the concessions 15 years prior to their expiration. This shall be from 1 January 2033 and for a period of 80 years.
Following three years of talks, the concession-granting municipalities have declared their support of a renewal of Salanfe SA’s concessions. On 29 December 2020, the communal presidents and the representatives of Alpiq and Salanfe SA, signed an agreement which formalises said intention and that defines the terms in principle of the new concessions.
In accordance with the Hydropower Strategy of the Canton of Valais, 60% interest shall be returned to the concession-granting municipalities upon renewal of the concessions.

The concession-granting municipalities shall yield half of their shares in the company, i.e. 30%, to the Canton of Valais, respectively Forces Motrices Valaisannes (FMV). Each municipality shall decide individually to sell its shares to one or more regional electricity suppliers, in accordance with the financial terms to be defined at the time of the disposal of the shares. In return for the renewal of the concessions, Alpiq shall transfer compensation to the amount of CHF 40 million to the concession-granting municipalities, CHF 12 million of which shall be transferred on 31 December 2020.
Based on the Agreement concluded by them, the parties shall now proceed to define the details of the terms of the implementation of the new concessions in cooperation with the Canton of Valais, FMV, and the electricity suppliers concerned. The legislative bodies of the concession-granting municipalities shall make a definitive decision on whether or not they are indeed to grant the renewal of concessions to Salanfe SA at the end of this process – at the latest in 2031.
