Ritom Pumped-Storage Plant Project – Tunneling under extreme conditions

The Ritom power plant in Ticino, which was built in 1920 and is located only a few kilo­meters from the Gotthard Tunnel, is in need of re­newal. Since 2018, a number of con­tract­ors from the Marti Group have been working on this over­all complex re­novation on behalf of Ritom SA.
