The Wertach power plant is a hydropower plant and an industrial and architectural monument in Augsburg-Rosenau and Thelottviertel . It is also known as the hydropower plant on the Wertach Canal and is part of Augsburg's historic water management system .
The Wertach power plant is located at Schießstättenstraße 19 at Gollwitzer Steg , a pedestrian bridge over the Wertach that connects the Rosenau and Thelott districts with Pfersee-Süd (Gollwitzerstraße).
history
The Wertach power plant was built in 1920/1921 by the city of Augsburg to supply power to the Augsburg trams . At the same time they put it to 1920 completed Wertach channel on which the 1884 dug factory channel extended a right derived from the Wertach side channel. The Wertach Canal flows immediately to the right of the Wertach past the Rosenau to the power plant and continues to feed the Holzbach and Senkelbach. The river bed of the Wertach at this point is now much deeper than the Wertach Canal.
The power plant is a hipped roof building over an L-shaped floor plan, the long leg of which is built across the Wertach Canal. At the eaves it is equipped with a circumferential serrated frieze . A building inscription let into the façade above the arched main gate shows as a relief a griffin carrying a pine nut on its back ; above it the inscription AD 1921 .
technology
The power plant still works today with machine sets from the time it was built. It was equipped with Francis twin turbines from Escher Wyss (throughput 1.25 m³ / s, head 4 m, speed 150 / min, power 460 kW). The generators are a three-phase generator , a direct current generator and an exciter (all from Siemens-Schuckertwerke ). The three- phase generator was operated as a three-phase motor for low water levels, “brook clearing” or repairs . He then drove the direct current generator so that the power supply for the tram was ensured.
The power plant is now in private hands. Today it only supplies alternating current; the DC machines run along idle. The turbine technology was renewed in 2007 in order to provide an output of 3.5 million kilowatt hours per year (400 kW) with an officially reduced amount of water.
