The Technical Excursion to Lilla Edet & Trollhättan locks will now also be available on Thursday 15 June.
This technical excursion will be visiting the hydropower plant Lilla Edet. This is one out of four hydropower plants in the river Göta Älv, draining the largest lake in Sweden, Vänern, flowing out in Kattegatt on the west coast of Sweden. The hydropower plants in Göta Älv are of great importance since they regulate the water levels in Vänern. Lilla Edet is under re-construction where the old spillways are being replaced. The new construction must be able to withstand higher expected waterflows then before. During our visit we will learn more about the re-construction which is planned to be completed by the end of 2025.
After our visit at Lilla Edet, we will go to the city of Trollhättan, located by Göta Älv. Göta Älv has six ship locks, of which four are in Trollhättan. The locks used in Göta Älv were opened in 1916 and are planned to be replaced by new locks by 2030. The construction of this project is planned to start by 2025. We will learn more about this project during our visit. We will also have a tour around the historical locks, with the oldest from 1800 to the once being used today.
