Origin and history
The Épusay wind turbine is a tower-type wind turbine machine designed by engineer E. Lebert, who holds the patents of the Auguste Bollée company from 1898 onwards. Installed in 1911 and inaugurated on 17 March 1912, it supplied the village with drinking water and also served its communal wash. Its operation was based on a reinforced concrete and brick tank, with a capacity of 200 cubic meters, ensuring a reserve in case of no wind.
High 21 meters with a 5 meters diameter turbine, this wind turbine was in operation until 1967. It symbolizes the technical innovation of the time, combining renewable energy and public utility. Its adjacent reservoir, classified with it by order of 12 June 1992, bears witness to its heritage importance and its historic role in rural modernization.
The town of Épusay, located in the Loir-et-Cher, has retained this monument as a communal property. Leolienne illustrates the industrial heritage of Auguste Bollée and his successors, including E. Lebert, who marked the history of hydraulic and wind technologies in France at the turn of the 20th century.
