The Bortel power plant is a two-stage small hydropower plant with a pumped storage stage on the north side of the Simplon area above Brig . It consists of the Bortelsee as head storage and the two machine houses Bortelalp and Ganterbrücke, near the bridge of the same name on the A9 . The underwater of the group is used by the Saltina ▼ power plant , with the Weri power plant as a fourth stage, the water could be used again before it flows into the Rhone .
The plant went into operation in September 1990 after a three-year construction period. By damming the Bortelsee on the Bortelalp, a storage basin with a capacity of 3.6 million m³ was created. The water comes mainly from the precipitation and the snowmelt in spring and summer, some is also pumped into the lake with the pumping system in the Bortelalp headquarters. The stored water is mainly used during the winter months to generate peak energy . One cubic meter of water from the lake can generate 3.5 kWh, which is one of the highest energy equivalents in Switzerland.
The water is in the center of a horizontal axis Bortelalp single-nozzle Pelton turbine processed, which has a capacity of 2.4 MW, while at a fall height of a 494 m of absorption capacity of 600 liters per second has. The two pumps installed in the headquarters each have an output of 1.3 MW, which makes the Bortel power plant one of the smallest pumped storage power plants in Switzerland.
In the central Ganterbrücke there is a two-nozzle, also horizontal-axis Pelton turbine with an output of 5 MW. It processes water with a fall height of 593 m and has a capacity of 1000 liters per second.
