hydro go electric

Change in Management

Wiegert & Bähr aided KIT- students

This year we were happy to donate the engagement of a group of students from the „Engineers Without Borders – Karlsruhe Institute of Technology e.V.” in their project in Sri Lanka.

The project concerns the installation of a so called Aquaponik facility, optimizing fish-farming and crop-production in a cycle. Development and design of the facility will be autonomously provided by 33 students from different branches of study. The facility will be erected in cooperation with local partners.

Amongst several new jobs the Aquaponik facility will extend the spectrum of food supply to the people in one of the poorest areas of Sri Lanka, which so far was formed by single-based food.

Start of erection of the plant is scheduled for march 2018

All donations will be used exclusively for locally purchased material. Entire expenditures for flights and accommodation will be borne by the students themselves.

Fish overcome large level difference with W&B fish lift, Kraftwerk Eglisau- Glattfelden, Switzerland

AXPO Switzerland have successfully completed the installation of two fish-lifts after two years erection time.

Due to the narrow topography a fish- lift was installed at the German side of the river to let fishes overcome the 12 m level difference of the banked-up water. W&B received the order for design, manufacturing and installation of this challenging fish climbing assistance feature. The new fish- lift is significantly smaller and cheaper compared to the existing fish ladders at the swiss bank of the river.





Sector gate for Rio Colorado, Chile

W&B delivered a sector gate with electric drive for a hydro power plant at the river Colorado in the Chilean Andes.

Due to transportation reasons the gates had to be designed in a split to 2 segment version. Installed to the bottom outlet of the wear at a height of approx. 1000 m a.s.l it will provide a safe discharge of the river with its huge amount of bottom load.

Turbine installations Arnstadt und Bienstädt, Germany

Energy from drinking water – Inauguration of the Francis turbines in Arnstadt and Bienstädt

The “Thüringer Fernwasserversorgung” in Erfurt, Thuringia, operates drinking water supply stations in several cities in Thuringia. W&B have delivered a Francis turbine unit with induction generator for each of the facilities in Arnstadt and Bienstätt. The output 0f 57 kW respectively 65 kW produced by energy recovery is used to supply internal consumers. The surplus energy is fed into the national grid.

Inauguration of hydro power station Bürglen, Switzerland

The new power station Bürglen of the AXPO- Kleinwasserkraft AG was formally inaugurated on September 5th, 2016.  With the new Kaplan turbine of W&B the regular annual production could be increased by 40% to 7 GWh.

In addition to the new turbine complete new hydraulic steel structures were delivered by W&B, mainly:

  • 1 fully automatic trashrack with folding arm trashrack cleaner
  •  2 rapid-action opening gates
  •   1 intake sluice gate of stainless steel

Inauguration of hydro power station Metzeral / Alsace, France

The formal inauguration of the hydro power station “Metzeral”  was celebrated with an open day on June 27th. Many hydro-interested visitors from the region, as well as politicians and industry representatives attended the ceremony when the start button was pushed and the W&B crossflow turbine began to turn.

This power station was built exceptionally eco-friendly. Nearly no impact was made on the environment. For guiding the discharge water to the turbine the existing penstock of a closed down textile factory is used to get an output of more than 250 kW.

Modernisation and revision of the power plants on the upper Danube

W&B received the order for revision and modernization of the hydro power plant Gundelfingen at the river Danube

Ordering party is the “Obere Donau Kraftwerke AG (ODK) with it’s plant operating company BEW (Bayrische Elektrizitätswerke GmbH) Augsburg, Germany.

Two vertical Voith Kaplan turbines were installed in the power station Gundelfingen in 1964. The two identical turbines with a runner diameter of 4’180 mm produce an output of 7’350 kW at a discharge of 210 m³/s.

In the mechanic-concerned part of the order revision of the guide vane assembly and the shaft bearing are included, as well as the modernization of the hydraulic turbine governor with adaptation of the runner adjustment system and a new high pressure servomotor.

The complete monitoring, supervision, and automatization of the turbine equipment will be modernized together with the wear control by KIMA Automatisierungs GmbH, Gronau, Germany.

W&B is looking forward to a fruitful cooperation with ODK and BEW after completion of the works in spring 2016, as it is intended to continue the modernization on the other 5 powerstations of ODK as well, which are Offingen, Faimingen, Günzburg, Leipheim and Oberelchingen.
