Visited on Sunday. Construction is in progress.
It's very close to the highway exit, just 2 turns, and the only traffic lights are those at the highway exit itself.
I counted 16 foundations for single dispensers along with 16 matching foundations for power cabinets. 2 of these chargers are at the end in a drive-through configuration. The locations that use ABB Terra HP system usually have 2 times as many power cabinets as stalls, but I noticed in Silvaplana that they have different hardware that only uses one power cabinet per stall, so it's likely the same system that will be used here.
There are 4 additional foundations in a staggered formation, likely for Hyperchargers serving 8 parking spots.
This would make a total of 24 charging spots, the largest IONITY station of Switzerland and at the top of the largest hubs in the country with Tesla. But Tesla don't have drive-through, 450kW or 800V at their 24 stalls hubs, so it would be the single largest in those metrics. IONITY might not equip all 24 stalls right away though, we'll see.
