Alstom Grid: a pioneer and leader with more than a century of expertise  

Utility and industrial customers across the globe have relied on Alstom Grid products and solutions for over a century. Today, Alstom Grid carries with it the pioneering spirit, technologies and expertise of all of its ancestors: AEG, GEC, Delle, English Electric, Sprecher & Schuh, AREVA, Cegelec, Passoni & Villa, to name just a few.

1872 Founding of Société Alsacienne de Constructions Mécaniques (SACM) in France.

1882 Founding of DEG in Germany, becoming AEG (Allgemeine Elektrizität-Gesellschaft) in 1887.

1886 General Electric Apparatus company formed in the UK. Later called General Electric co ltd (GEC).

1891 The first AC transmission line was built in Germany, thanks to two pioneers of electrotechnology: Michael von Dolivo-Dobrowolski, chief engineer of AEG, and Charles Eugene Lancelot Brown.

1898 Compagnie Générale d’Electricité (CGE) founded in France.

1900 Carl Sprecher sets up his company in Switzerland, and produced the first 10 kV-60 A horn switch. He is joined by his shareholder, Heinrich Schuh, in 1902.

1912 Inauguration of the AEG High-Voltage Institute. CGE acquires a holding in Delle (then “Ateliers de constructions électriques de Delle”).

1917 Arc suppression coil (“Peterson coil”) invented by AEG chief engineer Waldemar Petersen.

1919 First high voltage bulk-oil circuit breaker supplied by Delle at 120 kV, followed by 150 kV and 220 kV. (In the 1930s, Delle lead advances in minimum-oil circuit breakers.)

1920’s GEC, AEI and English Electric instrumental in creating the UK national grid. AEG develops air-blast circuit breakers.

1928 Founding of Alsthom through the merger of Société Alsacienne de Constructions Mécaniques (France 1872) and Thomson-Houston (USA, 1894).

1938 Vitaly Grosse, member of the AEG High-Voltage Institute proposed the use of sulphur hexafluoride (SF6) as a quenching medium.1964 UHV 1,050 kV power transformer is built and delivered in France.

1965 Delle-Alsthom created from the merger of Alsthom and CGE-Delle activities. The PK becomes the first circuit breaker in the world at 735 kV.

1968 GEC merges with English Electric.

1986 Sprecher and Schuh integrated into GEC Alsthom as Sprecher Energie.

1989 UK’s General Electric Company (GEC) and France’s Compagnie Générale d’Electricité (CGE) join together to form GEC Alsthom.

1998 GEC Alsthom acquires Cegelec, lists on the Paris stock exchange and is renamed Alstom.

2004 Alstom T&D joins Areva.

2006-09 Acquisitions of Ritz High Voltage, Nokian Capacitors, Nxtphase, RB Watkins, Powermann

2010 Areva’s Transmission activities are acquired by Alstom forming the Alstom Grid sector.
