List of the 350 largest electrical industry companies Germany [2025]

List of the 5 largest electrical industry companies in Germany

The electrical industry is one of Germany’s most important industrial sectors, generating sales of around €220 billion in 2024 and employing approximately 900,000 people. It is a major export sector, with over 50% of its sales coming from international trade. The industry is growing strongly, particularly in the areas of automation, electronics, and Industry 4.0. Companies such as Siemens and Bosch are driving forward digitalization and electromobility. The industry also plays a central role in the energy transition, particularly in wind and solar technologies, with investments of around €10 billion in green technologies in 2024. However, challenges such as raw material supply and geopolitical uncertainties remain. Below, we take a closer look at five highly relevant players from our list of the largest electrical engineering companies in Germany.
