Small Hydroelectric Power Plant Vrysochori
Location: Vrysochori Ioannina
Power: 1,56 MW
Technology: Hydraulic
The electromechanical equipment of the station is installed in a building approximately 110 m2, and includes Pelton type water turbine, of vertical axis, with 4 nozzles, a synchronous generator of 1700 kVA, a transformer of 1850 kVA, electro-hydraulic regulator, low and medium voltage cubicles and ancillary equipment.
The water intake consists of a small dam with 2 meters height and uses coanda type screen (for the first time in Greece). The pipeline, whose length is 2400 m, is constructed of GRP, in three equal parts, with diameters 1000 mm, 900 mm and 800 mm respectively. Part of the pipeline, with a length of 120 m, near the station is constructed by spirally welded steel pipe.
The entire pipeline is installed underground (with the exception of two river crossings).
The largest section of the pipeline (approximately 2000 m) is installed below the road Vrysochori – Palaioseli, without any aesthetic disturbance.
The section near the water intake, with a length of 350 m, is installed underground, along with the bank of the stream.
