Alpiq Group’s Forces Motrices Hongrin-Léman (FMHL) has officially inaugurated the second most powerful pumped storage power station in Veytaux (canton of Vaud), Switzerland.
The new CHF331m ($328.3m) power station has an output capacity of 480MW, which includes a 60MW reserve.
FMHL's board of directors chairman Pierre-Alain Urech said: “The new FMHL power station will make a significant contribution towards meeting our country’s future power supply challenges and is perfectly in line with the Energy Strategy 2050.”
The development of pumped storage power stations ensures the stability of the Swiss and European energy grid in regards to the rapid rise in wind and solarpower developments.
Switzerland's energy federal office director Benoît Revaz said: “Switzerland is fortunate to have a powerful hydroelectric infrastructure that enables it to take up the challenge of efficiently integrating intermittent energies into its energy system.”
Ten years after the first feasibility study was initiated, two new 120MW pump turbine groups are now operational.
The two groups have doubled the output capacity of the station from 240MW to 480MW, making the FMHL power station the second most powerful in Switzerland after the Linth-Limmern facility in the canton of Glarus.
The new station is expected to produce nearly one billion kilowatt-hours of peak electricity each year, which is equivalent to the power consumption requirements of approximately 300,000 Swiss households.
