The invention relates to a facility for producing backup electrical power for an electrical-current distribution system, including: at least one first water tank (311, 312) located at a first level; at least one second water tank (120) located at a second level lower than the first level; at least one pipe (340) for placing the first tank (311, 312) and second tank (120) in communication, and having at least one controlled valve (350); and at least one hydroelectric power plant (330) provided with pumping equipment. At least one of the first and second tanks (311, 312; 120) is built into the foundations at the lower portion of an artificial building (301, 303; 200A), the construction of which is rendered necessary by a separate primary function of a secondary function for producing electricity. The first tank (315) or the second tank (120) can form a common water area near ground level. The tanks (311, 312, 210, 220) built into the building foundations are particularly capable of cooperating with air-conditioning and heating equipment of the buildings at the bases of which said tanks are constructed, or of related buildings. |
