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.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
