World's first solar ski lift

2nd Quarter 2012 Electrical switching & drive systems & components

Using Siemens technology, the world’s first solar ski lift is being operated in Tenna, in the Swiss Canton of Grisons. The Skilift Tenna (GST) co-operative opted for technology from Siemens Industry Automation Division to modernise 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 metre long drag-lift is located at an altitude of 1644 metres 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 so-called solar wings are hung between position of the sun. The system produces a total power of about 90 000 kWh a year, two thirds of which are fed back into the grid at market prices, using Sinvert PVM string inverters. The drag-lift’s operation involves a significant number of automation components. A Simatic S7 programmable logic controller, enhanced with a fail-safe CPU and ET 200S modules, control the ski lift‘s movements. 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 is operated using a Simatic Touch Panel.
