The Oberesslingen power plant is a run-of-river power plant between two Neckar islands at river kilometer 195.6 in Oberesslingen , a district of Esslingen am Neckar .
power plant
The power plant was built in 1929 as part of the Neckar regulation based on a design by the architect Paul Bonatz . It has an output of 2.1 MW and supplies around 12.3 GWh of energy per year . The mean flow rate is 45 cubic meters per second. The power plant is operated by Neckar AG.
In 1930 the power plant was described in the journal for building trade as follows: “The power plant [...] is based on Keuper marl and has a concrete substructure , above it in clinker masonry . It contains two Kaplan turbines with standing waves with a maximum output of 2680 HP, which can process a maximum water volume of 45 m³ / sec on 123 days. The generators coupled with the turbines provide 1600 kVA at 167 rpm; the machine voltage of 3000 V is stepped up to 10,000 V. Around 11.5 million kilowatt hours are generated annually. The power plant is leased to Neckarwerke AG Eßlingen. "
Further buildings in the area of the Oberesslingen barrage
The right arm of the Neckar (Altneckar) is regulated a little above the power plant at river kilometer 196.5 by a weir with three water passages. This structure was built in 1954 and has been restored since 2006. A rifle brigade designed by Paul Bonatz and built from 1926 to 1928 had already existed in the same place . The subsequent installation of an emergency lock was planned during construction. Bonatz's weir had three openings, each 17.5 meters wide, with 5 meter high gates. It was designed for 1000 m³ / sec. For larger amounts of water there was still a flood area on the right bank of the Neckar available, although an expansion of the weir was already planned in the event that this area was settled.
The shipping route leads through the lock canal to the left of the Neckar Islands. At river kilometer 194.84 is the barrage Oberesslingen , which was built in 1968. It was built as a double lock, but so far (as of August 2010) only the left lock chamber has been used. It is 110 meters long and 12 meters wide and enables a lifting height of 5.91 meters; the reservoir target in the upper water is 242.24 meters above sea level . An extension of the lock using the unused right chamber is planned. In addition to the lock chambers, there is also a slipway for smaller vessels. The unoccupied lock, like the weir, has been remote-controlled from the remote control center of the Stuttgart Waterways and Shipping Office in Oberesslingen since 2003.
In Bonatz's time, the larger ships on the Neckar stopped in Heilbronn . The construction of the locks had already been envisaged, but was only to take place at a later date: “[...] the locks will initially be left out. The current continuous shipping does not suffer from this [...] Only a few barges go to Lauffen above the Horkheim barrage , which is why a lock for smaller barges was built at this stage. Incidentally, the later implementation of the large shipping to Plochingen has already been largely prepared as part of the overall plan for the Neckar canalisation. "
