The Reckingen power plant is a run-of-river power plant on the Upper Rhine , around 700 meters above the Rekingen train station . Because the power plant building is located on the Baden side of the Reckingen district of the municipality of Küssaberg , the spelling with ck is used and not the spelling of the municipality of Rekingen on the Swiss side.

history

The power plant was built between 1938 and 1941, although the concessions were granted in 1928. The additional licenses, which were granted in 1938, run until 2020. The request for renewal of the license was submitted on time.

The power plant was planned by Motor-Columbus  AG in Baden. The company also provided the site management; the local site manager was the engineer Dr. F. Gugler.

The ship lock planned on the right bank of the Rhine (on the Baden side) was not implemented.

Initially, the power plant was operated by Lonza in Basel, and according to the original contract, 50% of the output and the energy generated were distributed between Switzerland and the state of Baden. Today the ownership structure is regulated as follows: EnBW Energie Baden-Württemberg AG holds 50%, AEW Energie AG 30% and Axpo Power AG 20%. Axpo Power AG has been responsible for operational management since 2003.

technology

The power plant dams the Rhine at a height of 335.2  m above sea level. M. and a length of 11.5 kilometers, and thus extends into the underwater area of the Eglisau power plant . The weir and the power station building together form the barrage. The weir has a clear width of 69 meters and three openings of 20 meters. The double shooters have a height of 12 meters and are trained as six meter high hackers. In the upstream water, three dam beams are planned as an emergency seal . There is a fish ladder on both sides of the river . The boat ramp is on the Swiss side.

The machine house has a basic dimension of 64.6 by 18.5 meters and houses two vertical-axis machine groups. These each consist of a Kaplan turbine with an absorption capacity of 280 m³ / s, to which a three-phase generator with an output of 22,000  kVA is directly coupled. This generates a voltage of 11 kilovolts at 75 revolutions per minute  at a frequency of 50  Hertz . With the help of transformers, the generator voltage is brought to 50 kilovolts for the Swiss derivative and 110 kilovolts for the German derivative.
