On 11 October 1922 the council appointed a commission to study the connection of the village to a power grid. On 9 May 1926 appropriations for the establishment of a union for electrification were voted. On 30 October the mayors of Cardaillac, Fourmagnac, Fons, Reyrevignes, and Assier met and decided that the electric current should be supplied by the hydro-electric plant of Mr. Barrière located on the "Drauzou" but in 1927 the council denounced the agreement with Mr. Barrière on the grounds that his plant could not supply power permanently because the flow of the Drauzou was too irregular. In 1928 the commune had to pay a 225,000 franc fine for non-compliance with the agreement but appealed and was successful in 1932.
