The edifice was completed in 1906 in art nouveau stile by the mason Jean Gemünden. It’s composed from an engine hall and a westward added living quarter for the keeper (machinist). The facade is structured by high windows with sprout frames. The living quarter is in „Landhaus“–style with framework and an elegant helmeted roof.
This old power plant is a proof of the economical prosperity of Ober-Ingelheim in the early 20th century. Until 1945 two Diesel engines with a total of 100 HP (horsepower) powered the DC –generators. As early as 1914 it was necessary to get additional power supply from Mainz. After the city of Ingelheim was founded in 1939, the power was changed from DC to AC.
