The world’s first solar ski lift equipped with Siemens technology

06.03.2012
The world’s first solar ski lift is being operated in Tenna, in the Swiss Canton of Grisons.

The “Skilift Tenna” (GST) cooperative opted for technology from Siemens’ Industry Automation Division to modernize its drag-lift.


Since its commissioning in late 2011, the solar ski lift has produced three times more solar power than that required to operate it and has doubled the number of people it can transport.

The 460 meter long drag-lift is located at an altitude of 1644 meters in the holiday resort of Tenna and required refurbishing after 40 years in operation. To achieve this, GST opted for a combination of a photovoltaic system and automation.

The newly installed photovoltaic equipment associated with the drag-lift is based on a solar wing system, whereby 82 photovoltaic modules forming socalled solar wings are hung between two ropes and automatically track the position of the sun.

The system produces a total power of about 90,000 kWh per year, two-thirds of which are fed back into grid at market prices, using Sinvert PVM string inverters.

The draglift’s operation involves a significant number automation components. A Simatic S7 programmable logic controller, enhanced with a fail-safe CPU and ET 200S modules, control the ski lift‘s operation. The refurbishment made it possible to double the hourly transport capacity to 800 persons.

The exchange of data between the lift’s mountain and valley stations is also based on Siemens technology, using an IM 151-3 interface module from the ET 200S distributed peripherals range.

The entire ski lift system in Tenna is operated using a Simatic Touch Panel.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
