The Nagold hydropower plant is a run-of-river power plant in the city of Nagold in the Calw district . It went into operation in 1893 as the third private power station in the Kingdom of Württemberg . Parts of the facility are under monument protection .
history
In 1891 the sawmill owners Cletus Klingler and Paul Barthel bought the Lehr's grain mill on the Nagold, which had burned down a year earlier . They planned to use water power to generate electricity and transmit it to their sawmill in the Iselshausen valley via a line . The machine works in Esslingen took over the execution . The mill wheel was replaced by a Francis turbine with 43 hp . A belt-driven generator produced direct current with a voltage of 110 volts. In January 1893, the line to the sawmill, 1.5 km away, went into operation.
The Nagold teacher training college and some citizens also showed interest in the electric lighting, which was still expensive at the time. In June 1893, 70 houses with over 400 light bulbs and 7 electric motors were connected to the new line network, which led from the old church tower via masts and roof stands to the consumers.
In 1894, Klingler expanded the power plant to include a steam locomotive with 20 hp and a connected generator as a reserve for peak loads and low water. A battery system should compensate for voltage fluctuations in the lighting network.
To meet the increasing demand for electricity, Klingler built a second hydropower plant from 1899 to 1901 on Bettenberg, 6 km away . The three-phase current generated with a voltage of 5000 volts was transformed to 220 volts in Nagold. The power generation in the Nagold power station was also switched to three-phase current in the following years. From 1909 a steam engine with 150 hp was used as a reserve.
After Cletus Klingler's death in March 1904, his son-in-law Ludwig Wohlbold took over the management of the power company C. Klingler's heirs .

The Nagold correction carried out in 1927/1928 required the construction of the weir system . The power plant received two new Francis twin turbines with an output of 150 hp in order to use the gradient, which has now increased from 1.8 m to 2.9 m. In 1921 and 1930, two submarine diesel units, each with 420 HP (309 kW) power, were installed to compensate for the peak load, which were in operation until 1985.
In 1989 Energie -versorgung Schwaben AG (EVS, from 1997 EnBW ) took over the Nagold electricity plant. In 1991 the generators were replaced and operations were automated. The power plant has been privately owned again since 2004.
