Come and join us!

efa:ON is the only trade fair for electrical, building and lighting technology in Central Germany and the neighbouring regions.

At efa:ON, manufacturers and service providers meet trade visitors from the trades, industry, commercial and energy supply companies, retailers, planners, architects, engineers, building operators and investors, as well as the next generation of the industry. As the industry's central information and communication platform, the combination of exhibition, specialist programme and event offers trade visitors great professional added value through exchange and further training.

Parallel to the established trade fair efa:ON, the netze:ON - Trade Fair for Energy Technology, Distribution and Broadband Networks has been taking place since 2023. This parallelism creates a thematic bridge to present the networking of buildings in distribution and broadband networks. Together, the trade fair alliance for the energy transition represents the diversity of electrical engineering as well as electrical and sustainable energy technology.

The next edition of efa:ON will take place from 23 to 25 September 2025 in Leipzig.
