Monday the 24th of January, we had the successful breakthrough for the 1065 m tunnel for Tverrelvi Hydro Power Plant.
Breakthrough exactly in the centre of the few square meters set out for connection to the pressure shaft in the already prepared intake construction.
We will now push diameter 710 mm steel lining from bottom and up to complete the shaft before handing over to our customer NGKU who can plan to start production of another 12 GWH of new renewable hydropower in a few months.
