Ateliers de Constructions Electriques de Charleroi
electrical engineering company
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.
After World War II the company expanded into electronics, and became a contractor to the nuclear industry. The company was acquired by Westinghouse 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.
History
Background, 1878–1904
In 1878 Julien Dulait (1855–1926), son of steelworks engineer Jules Dulait began experiments into electrical and hydraulic machines; with co-worker Désiré Barras he created an electricity generating machine powered by an hydroelectric turbine. In 1881 the Compagnie générale d'Electricité was formed in Charleroi with Dulait as consulting engineer, constructing machines to Dulait's designs and those of Zénobe Gramme.
In 1886 the company was renamed becoming Société anonyme Électricité et Hydraulique à Charleroi (E&H), by this time the factory was producing dynamos with over 100 kW power. By 1900 the company had supplied electric lighting to the cities of Liege, Charleroi and Schaerbeek, and opened a new 50 ha (0.50 km2) factory in Marcinelle/Marchienne. In 1904 the company supplied trams for a line in Cointe, Liege- – the first entirely Belgian built trams.
This brief starts where responsible research should: with the source description of “Ateliers de Constructions Electriques de Charleroi” as electrical engineering company. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as electrical engineering company. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jul 14, 2026. The linked authority identifier is Q848270. The first chronological checks are 1970, 1985, 1989 and 1878.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
