Bjufors HPP, a power plant owned by Statkraft, is located on the Umealven River in northern Sweden. It consists of two units with a total power of 42 MW. Similar to Bergvik, in 2023, we carried out mobile machining services at Bjufors for Unit 1, and this year, the same scope of work is being performed for Unit 2. The scope includes: machining of the rotor chamber (spherical surface).
Balforsens HPP, a power plant owned by E.ON, is located at the Ume reservoir dam in northern Sweden. It consists of two units with a total power of 88 MW. In 2024, we carried out mobile machining services at Bjufors, focusing on the machining of the runner chamber – spherical surface, for Unit 1.
Ojeforsen HPP, a 28.8 MW power plant owned by Fortum, is located on the Ljusan River in northern Sweden. In 2024, we carried out mobile machining services at Ojeforsen, focusing on the machining of the runner chamber – spherical surface.
Hydroelectric power plant of Chaira (Chaira PSHPP) was built in the Rila Mountains, about 100 kilometers southeast of the Bulgarian capital, Sofia. Chaira has a generating capacity of 864 megawatts (1,159,000 HP) and a pumping capacity of 788 megawatts (1,057,000 HP). The plant is equipped with four reversible Francis-type pump-turbines, each with a power of 216 megawatts (290,000 HP) in generating mode and 197 megawatts (264,000 HP) in pumping mode. Units 1 and 2 have been in operation since 1995, and during that time, Chaira was the largest pumped-storage power plant in southeastern Europe, with the highest single-stage pump-turbine drop in the world (690 meters in generating mode and 701 […]
