This study tour supported by Alpiq provides World Hydropower Congress delegates with the opportunity to visit some of Switzerland’s most impressive hydropower achievements: the under-construction Nant de Drance hydropower plant and the country’s second largest pumped storage power station Forces Motrices Hongrin Léman.

Delegates can book onto study tours when registering for the Congress. If you have already registered and would like to add a tour to your booking you can do so via your ‘MyArea’ page.

Nant de Drance hydropower plant

The Nant de Drance hydropower plant, currently under construction, will be one of the most important energy infrastructure projects in Switzerland. It will produce and store electricity using the difference in level between the lakes of Vieux-Emosson and Emosson in Valais.

Currently work is concentrated in the machine cavern where the six pump-turbines are being assembled. The plant will be commissioned by 2019. With a power of 900 megawatts and very high flexibility, Nant de Drance is perfectly adapted to the new energy context. It will be an essential instrument for the stability of the Swiss and European electricity grid.

The shareholders of the company are Alpiq (39 per cent), SBB (36 per cent), IWB (15 per cent) and FMV (10 per cent).

The 480 MW Forces Motrices Hongrin Léman (FMHL) power station is currently Switzerland’s second largest pumped storage power station. It generates electricity when demand is high from the waters of Lake Hongrin (Canton of Vaud). When electricity supply exceeds demand, the waters of Lake Geneva are pumped 880 metres higher, back to Lake Hongrin.

In 2017, FMHL commissioned a new pumped storage power plant, doubling the capacity of the previously 240 MW facility.

The shareholders of FMHL are Romande Energie (41.14 per cent), Alpiq (39.29 per cent), Group E (13.14 per cent) and the Municipality of Lausanne (6.43 per cent).

Programme:

  • Arrival in Lausanne on Friday afternoon (17.5.19, to be organised by the participant)
  • Overnight stay in Lausanne (to be organised by the participant)
  • Saturday: Visit to the FMHL Power Plant in the morning followed by a lunch (organised and offered by Alpiq)
  • Individual return journey (to be organised by the participant)
