How it started
Pre-World War I
The company was founded in Essen in 1898, as Rheinisch-Westfälisches Elektrizitätswerk Aktiengesellschaft (Rhenish-Westphalian Power Plant) by Elektrizitäts-Actien-Gesellschaft vorm. W. Lahmeyer & Company (EAG) and others. The full name was used until 1990 when it was renamed to RWE AG. Its first power station started operating in Essen in 1900. In 1902, EAG sold its shares to a consortium formed by Ruhr industrialists Hugo Stinnes and August Thyssen.
In 1906, it expanded its operations beyond Essen by acquiring Elektrizitätswerk Berggeist AG in Brühl, and Bergische Elektrizitätswerke GmbH, Solingen. During the same year, it also acquired shareholdings in the tramway companies Bochum-Gelsenkirchener Straßenbahn AG and Rheinische Bahngesellschaft AG.
In 1908, RWE signed demarcation contracts with Städtische Elektrizitätswerk Dortmund and Elektrizitätswerk Westfalen AG. Together they created Westfälische Verbands-Elektrizitätswerk AG. RWE contributed to the newly established company by its power station in Dortmund–Kruckel and the supply grid in Witten/Dortmund. Later all these companies formed Vereinigte Elektrizitätswerke Westfalen AG (VEW).
In 1909, RWE opened the Reisholz Power Plant and acquired a stake in the tram company Süddeutsche Eisenbahngesellschaft AG. RWE also started to build its own gas supply network in 1909. Deliveries of coal gas to the Bergisches Land region started in 1912. In 1914, RWE opened Vorgebirgszentrale power plant in Hürth. By 1920, the plant had installed capacity of 190 megawatts, which made it the largest in Europe.
Before World War I, municipalities of Essen, Mülheim an der Ruhr, and Gelsenkirchen, became shareholders in RWE. By the 1920s, Bonn, Cologne, Krefeld, Duisburg, and Düsseldorf also became shareholders and municipalities owned the majority of RWE's shares. In 1925, the Prussian state became a shareholder in RWE. In 1929, municipalities and the Rhine Province combined their shareholdings into a holding company Kommunale Aufnahmegruppe für Aktien GmbH.
