In the first stage fortified house for jezného, tunnels were 1323 meters long, shaped with the help of dynamite in hard rocks, and úboční channel with a length of 437 meters, which brings water from the gallery built in the buffer chamber. In the second stage, the engine room, the substation, and buffer were mixed with a downcomer chamber and cascades for draining excess water again implemented in Jizera. Water was carried from the chamber pressure pipes in the engine room to two Francis turbines and generators on a common shaft. The engine compartment is immediately adjacent to a high building with eight substation transformers.
