Austrian ECO – power plant pipeline

Another noteworthy hydro project that was recently realized with HOBAS CC-GRP Pressure Pipe Systems is the small-scale power plant at the Loibl Stream in Carinthia, on the border to Slovenia. The plant is run by a group of 8 different entrepreneurs including the planner and turbine manufacturer. It consists of a timber intake structure, a 2080 m HOBAS Pressure Line DN 1400, SN 5000, PN 2 to PN 8 and the powerhouse with a tail water channel. The gross head is 39 m, the average flow amounts to 2.3 m³ per second. The plant has a capacity of 740 KW and an average of approximately 3.5 GW can be generated per year. The CC-GRP Pressure Pipe Line was installed by open cut in the embankment of the Loibl Stream, which had to be cleared before construction works could be started. An installation rate of 6 pipes (36 m) per day was calculated due to difficult site conditions. However, well scheduled construction works, on time deliveries, a well trained construction team, and the extensive project support by the HOBAS Team more than doubled the rate to 14 pipes (84 m) per day. This is an outstanding performance under given conditions – the construction company could finalize the project ahead of schedule.
