In spite Germany uses the same electricity system than Norway, there is beside the fact, that Norway uses almost decentralized and Germany centralized generation of 16.67 Hertz AC a very remarkable feature: in Norway some of the substations are in blind ending tunnels! Examples are in Holmlia at 52°49′42″N 10°47′55″E at in Hønefoss at 60°11′57″N 10°09′11″E and in Asker at 59°49′48″N 10°25′46″E. Why were they built in tunnels? Only for noise protection? Or had this military reasons?
Has someone pictures? If yes, then post them please.

I've passed the substation in Asker hundreds of times. Not much to see really. Just railway tracks leading into a steel gate and power wires leading out. The generators are wheel mounted in case they are need somewhere else on the grid.
Quite possible that there's a strategic/military reason. Quite a few part of the critical infrastructure in Norway is placed in mountain vaults.

Same about the Holmlia one, which I've passed some hundred times. Not much to look at:)
