The history of Siemens in Azerbaijan goes back 150 years. In the year 1864, the Siemens brothers purchased copper fields in the Kedabek area of Azerbaijan and started mining. In 1901, the Bibi-Eybat power plant, one of the most efficient of its day, was set up with participation of Siemens.
In 1867, Siemens completed the 11,000 km Indo-European telegraph line from London to Calcutta, part of which went through Azerbaijani territory. In 1998, when Azerbaijan was politically stable and continuing to grow economically, Siemens established a representative office in Baku.
