Founded in 1870 as the Society for Electric Light and Telegraph Construction Barthel Berghausen and Co. in Ehrenfeld, Germany, it later evolved into Helios AG on July 31, 1884.
Named after the Greek sun god, Helios AG quickly established itself as a leader in innovation, particularly in the field of electricity generation and distribution.
The company pioneered the development and implementation of alternating current (AC) systems, manufacturing complete electricity plants that were deployed across Europe.
However, despite its initial success, Helios faced challenges in the early 20th century due to declining demand and financial setbacks, including a loss-making acquisition.
Throughout its existence, Helios AG left a lasting impact on the field of electrical engineering, contributing to advancements in power plant technology, public lighting, and transportation electrification.
