A big infrastructural project in the Alps poses many challenges for business organisations, inhabitants and environmental associations. For instance, the engineering challenges facing an alpine plant like the pumped-storage power plant Linthal with its approximately 1,000 metre long concrete dam, two caverns inside the mountain more than 100 metres long and approx. 60 metres in height relate primarily to the transport logistics and safety of the workers employed there. 


The lecture discussed the future of hydropower taking the Linthal Project 2015 as an example. The largest pumped-storage power plant in Switzerland uses four pumped-storage turbines, each with a capacity of 250 MW and synchronous motors for variable speeds. This project represents an investment of approximately CHF 2.1 billion and is expected to take about five years. The plant, which will go into operation in 2015/16, will play a pivotal role in Switzerland’s future energy supply.
