Deutsche Edison-Gesellschaft uses 3 million German Marks to set up the public limited company 'Städtische Elektricitäts-Werke'. It is tasked with the commercial exploitation of electricity for lighting and power transmission in the current and future municipal area of the city of Berlin. This is the birth of the Berliner Elektricitätswerke (Bewag).
On 15 August, the first public power plant in Germany starts operating at Markgrafenstrasse 44 with 540 kW.
Rahtenau acquires shares in the Städtische Elektricitäts-Werke, saving it from the first crisis. Despite everything, capacity is expanded. In March, the second power plant starts operating in Mauerstrasse (285 kW).
In November, the networks of the two power plants in Berlin were connected, creating the first grid. Deutsche Edison Gesellschaft becomes the Allgemeine Elektricitäts-Gesellschaft, AEG. It takes over the management of the Städtische Elektrizitäts-Werke, which are renamed 'Berliner Elektricitäts-Werke'.
Transformation of the company into a municipal public limited company under the name 'Berliner Städtische Elektrizitätswerke Aktiengesellschaft' (Bewag).

Appointment of a joint Board for the companies Bewag and HEW, each with co-determination bodies.
Bewag becomes Vattenfall Europe Berlin AG.
Vattenfall loses approximately 250,000 customers in Berlin and Hamburg. It is due to a combination of an increased number of customer switching electricity provider, Vattenfall’s bruised reputation caused by broad media coverage of the rate increase announcement and the outages at the Krümmel and Brunsbüttel nuclear power plants. Vattenfall’s market share thus falls from roughly 85% in Berlin and 90% in Hamburg, to 79% and 83%, respectively.
Vattenfall collaborates with BMW in an electric car project. Some 50 “Mini E” cars drive the streets of Berlin, where Vattenfall installs special charging posts at the test drivers’ homes.
Vattenfall sells its subsidiary 50Hertz Transmission GmbH, which owns and operates Vattenfall’s German transmission grid, to the Belgian transmission system operator Elia and to the Australian Industry Funds Management (IFM).
Vattenfall phases out coal in Berlin power plant.
Vattenfall invests 325 MEUR into a new gas-fired combined heat and power plant in Berlin.
