In order to replace an existing ski lift, the Skilift Tenna Assocation con-structed the world’s first solar ski lift in 2011. The 450 m long new ski lift is supported by five towers. So-called solar wings were installed on a length of 330 m. The swivelling solar wings can be adjusted to the solar radiation, which produces the energy required to operate the ski lift. The remaining energy is sold to an electricity con-sumer.
The Chur office of Pöyry Switzerland contributed to this project with the following services:
- Design of all foundations (tower foundations, lower and upper station, excavation plans)
- mountain and valley guy-wire
- structural calcula-tions of all foundations and guy-wires
- and technical supervision of construction works (including invoicing)
