03/07/2024: Ryburg-Schwörstadt, Switzerland — Major milestone achieved: new runner installed

In the context of the major rehabilitation project of the hydroelectric power plant in Ryburg-Schwörstadt on the northern border of Switzerland, another important milestone was achieved: the new Kaplan runner along with the completely refurbished turbine block was lifted into the pit.

© ANDRITZ

The new oil-free runner was designed at ANDRITZ Finland (following a fully homologous model test), then manufactured by ANDRITZ Germany and assembled on site by the ANDRITZ Switzerland team.

With a total weight of over 240 tons, the lifting was an impressive sight, fitting the head cover over the previously installed 24 wicket gates (fully refurbished at ANDRITZ Graz) requiring precision maneuvers from the site staff.

The first unit is scheduled to be commissioned during summer 2024, followed afterwards by the rehabilitation of the remaining three machines at a cadence of one per year.

11/06/2024: Piottino, Switzerland - Contract for the rehabilitation of the 3 Francis groups

In April 2024, AET (Azienda Elettrica Ticinese) awarded the ANDRITZ/INGETEAM consortium (Spain) the contract for the supply of the electromechanical equipment for the rehabilitation of the Piottino hydropower plant in Ticino.

© ANDRITZ

The Piottino hydropower plant was built between 1928 and 1932 by Officine Elettriche Ticinesi. Originally equipped with two vertical Francis units, it was extended with a third unit in 1957, increasing the total power plant output to 67 MW. The plant produces around 310 GWh per year, which corresponds to the needs of 77,500 households. AET has been operating the plant since 1972, after the water utilization concession expired and the hydropower plant was taken over by the County of Ticino.

In recent years, AET has carried out an extensive modernization program for the power plant, the main objectives of which are the replacements of the electromechanical equipment and the power plant's valves.

As part of this extensive refurbishment program, ANDRITZ Switzerland and its partner INGETEAM will supply the turbines, generators, and auxiliary systems. The delivery of the units will be staggered, with the rehabilitation of the first group taking place in April 2027, and the last one in April 2029. A model test will also be carried out in our hydraulic laboratory in Linz, Austria to optimize the hydraulic performance.

ANDRITZ and its partners would like to thank AET for the trust placed in them and look forward to the successful realization of the project.

15/11/2023: France – Grand’Maison HIPASE-E 

For a year now, the first HIPASE-E’s were installed for our customer EDF (Électricité de France).

© ANDRITZ

These new regulators were all commissioned at the Grand'Maison power plant, which is the largest hydroelectric power plant in France.

The voltage regulation has been upgraded on four units; two Pelton turbines of 170 MW and two Francis pump turbines of 153 MW.

These imposing electrical THYNE 500 cabinets were developed by our specialists in Vienna, Austria, and the Automation Team from Vevey, Switzerland, had the opportunity to train with our experts for the commissioning of these controllers for static exciters of over 1,000 A.

To maintain all the flexibility of the installation, the back-to-back starting of the units also had to be optimized and validated. Any Pelton launcher (with HIPASE-E or an older system) can start any pump (also with HIPASE-E or an older system).

Three more units will be modernized next year and commissioned by the Automation Team in Vevey. The last five machines should follow in the upcoming years.

07/09/2023: Successful completion of apprenticeship as design engineer (Federal Certificate of Competence)

I was able to complete my apprenticeship as design engineer after having spent four years at ANDRITZ Hydro AG in Kriens, Switzerland, where I started in summer 2019.

© ANDRITZ

The first two years were very intensive. I started the first year with a 6-week training course at Schindler AG in Ebikon and ended it with short-time work during the Corona pandemic. Despite the circumstances, I learned many basics and enjoyed good training and preparation for the partial examination in the second year of my apprenticeship. The approx. 4-month workshop internship, which I also was allowed to complete at Schindler AG, helped. After having successfully passed the exam, I moved to a productive department for the first time. I spent the entire third year of my apprenticeship there. In this department, I was able to help out with productive work for the first time and show what I had learned. With a lower workload, I could use the time to dedicate myself to the company directives and standards. With a lot of new knowledge, I then entered the fourth and final year of my apprenticeship. I moved to the Turbine Engineering department. I had great respect for this apprenticeship year, as I assumed more that would now be expected from me. However, this pressure eased as I was allowed to contribute with my own suggestions in finding solutions which were also honestly taken into account. This gave me a lot of motivation to further work hard. I was always happy to accept new assignments and wanted to learn more.

I also found the cooperation with all employees in the different departments very pleasant. I consider the ANDRITZ Hydro AG product to be very useful for the environment and climate, which motivated me to go to work every day and to give my best.

During my apprenticeship, I was able to work on many different projects. The Bieudron project, Switzerland, in particular took up a lot of my daily work. I also often had work assignments on my desk for other projects such as Svelgen, Norway, or Ryburg, Switzerland. Some of these were very challenging, but also very exciting.

I enjoyed finding solutions for assignments and designing. I was often entrusted with more difficult tasks. When I was able to complete them successfully, it was always a great sense of achievement.

I will certainly continue to work for ANDRITZ Hydro AG until the end of 2023. After that, I will have to complete my military duties. What comes after is still open. But I will always look back on my apprenticeship with pleasure and I would like to take this opportunity to thank all my colleagues for the good cooperation and training.

The hydropower plant is equipped with six Francis units with a capacity of 11.8 MW each. The project is financed by Ivanhoe Mines and the final client is SNEL, the engineer is the consulting company Stucky from Switzerland. 

Mwadingusha power plant located on the Lufira river was originally commissioned in 1930 and the original supplier is Charmilles - Geneva. Until this date there was no mayor overhaul of the power plant. 

The scope of supply for ANDRITZ comprises the replacement of six turbine units, generators, governors, inlet valves, exciters, voltage regulations, and draft tube stop logs, rehabilitation, and replacement of the penstocks, rehabilitation of gates and intake valves including dismantling, erection, and commissioning. The transformers and the BoP part were in scope of Cegelec. The whole project is based on the multi-location involvement of our teams from Switzerland, India, and Austria. The original discharge and net head are unchanged, so there is only slight power increase from 12.8 to 13.05 MW per unit. 

The site mobilization started mid-August 2017 and was followed by dismantling of the old equipment from November until April 2018. The erection was executed from 2018 to 2021, though the project planning was impacted by the Covid pandemic. The first unit was commissioned in February 2021 and the last of the six units in November 2021. All the trial run periods were successfully completed, and all the units are currently in commercial operation supplying electricity to the Congo National grid as well as to the copper mine of Kamoa and Kakula, owned and operated by Ivanhoe mines.

Aside of the wear and tear of the units, the abrasive water of the river Inn leads to above-average wear and thus to premature loss of efficiency. Consequently, the turbines of the hydropower plant need a general overhaul. For economic reasons the customer has decided to replace the runners instead of repairing them.

ANDRITZ was awarded the contract to rehabilitate all four units of the Pradella hydropower plant and to replace the existing runners with new, coated ones. ANDRITZ’ solutions for erosion-resistant coating of hydropower components are also used around the world. ANDRITZ’ top-tier SXHTM coating allows for the highest abrasion protection, a prolonged life span, and reduced maintenance costs.

The rehabilitation of the four units is scheduled until 2024.

Thanks to these rehabilitation measures, the reliability of the power plant is secured for the coming years. Particularly pleasing is the expected improvement in overall efficiency of 1 to 2 % because of the renovation. This will enable an additional 3,000 households to be supplied with renewable electricity from Engadine hydropower in the future.
