SA Ateliers de Constructions Electriques de Charleroi (ACEC) was a Belgian manufacturer of electrical generation, transmission, transport, lighting and industrial equipment, with origins dating to the late 19th century as a successor to the Société Électricité et Hydraulique founded by Julien Dulait [nl].

After World War II the company expanded into electronics, and became a contractor to the nuclear industry. The company was acquired by Westinghouse^[1] in 1970; in 1985 Westinghouse's share was acquired by Société Générale de Belgique (SGB) and Compagnie Générale d'Electricité (CGE).

The company operated at a loss during the 1980s, and was split and sold; Alstom and its affiliates acquired the majority of the company, along with ABB and Alcatel Bell and others. The remnants of the company were merged into Union Minière in 1989, forming ACEC Union Minière.
