An installation for producing supplementary electrical energy for an electricity network includes at least first and second water reservoirs, the first water reservoir () being situated at a first level and the second water reservoir () being situated at a second level lower than the first level, a communicating pipe () between the first water reservoir () and the second water reservoir () being provided with a remote-controlled valve (), and a hydro-electric generating system () being provided with a pumping installation. The first and/or second water reservoir () is integrated in the foundations in the lower portion of an artificial building (A) that needs to be built for a primary function independently of a secondary function of producing electricity. The first water reservoir () or the second water reservoir () may constitute a common body of water in the vicinity of ground level. The water reservoirs () integrated in foundations of buildings may in particular cooperate with installations for air-conditioning or heating the buildings at the base of which they are constructed, or associated buildings.
