The Société Électrique de l'Our (SEO) operates the pumped storage facility in Vianden. To produce peak current, the facility built an 11th turbine unit providing approximately 200 MW of power. The commissioning of Unit 11 will bring the plant's total capacity to 1,290 MW.
At the same time, the storage retention capacity of the reservoir has been increased by 500,000 m3. To achieve this, the crest of the upper reservoir wall was raised by 1m. Water is stored in the lower reservoir, which was raised by 0.5m.
The visitor's centre and underground operating facility are open every day from 10am to 4pm. Between Easter and September the site is open until 8 pm.
Furthermore, SEO also operates the run-of-the-river hydroelectric and wind turbines facilities.
