From June 16 to 18, 2026, the Swiss electricity and energy industry will gather at Powertage 2026 at Messe Zürich. As the industry’s leading networking platform, Powertage brings together companies, experts, and decision-makers to discuss current developments, innovations, and solutions for the future of energy.
Semax AG will be there again this year. Stop by our booth—in the same location as always—and talk with our team about current challenges and solutions related to smart metering, the upcoming rollout, and data platforms for energy providers.
We look forward to seeing you at Powertage 2026 at our booth F30 in Hall 4.
The Amera Head End System (HES) was successfully recertified on January 15, 2026, for another five years. The independent audit confirms that the system meets all data security requirements for smart metering systems. The Amera HES ensures end-to-end encrypted communication across various communication architectures. These include point-to-point connections via LTE or FTTH and mesh-based networks that communicate via G3 PLC in both the FCC and Cenelec A bands, which are connected via Amera HES data concentrators. This ensures that measurement data is securely transmitted and processed at all times, regardless of the communication technology used.
With this successful recertification, the Amera Head End System reaffirms its role as a long-term, secure, and regulatory-compliant platform for the Swiss smart meter rollout. For network operators, this means a high degree of investment security as well as the assurance that their infrastructure meets the current and future requirements of the digital energy world. At the same time, a certified and secure communication platform lays the foundation for future smart grid applications and the further digitalization of the Swiss electricity market.
Semax AG is celebrating its 15th anniversary this year. Since our founding, we have been committed to providing innovative metering solutions and practical systems for energy utilities. We are particularly proud to be the only Swiss manufacturer of electricity meters for the energy utility sector—developed and produced in Cham and Steinhausen.
We would like to celebrate this anniversary together with the Swiss electricity industry. That is why we cordially invite 15 delegations from energy supply companies to visit us in Cham. Look forward to a relaxed lunchtime get-together, engaging discussions with industry colleagues, and an exclusive tour of our company. You’ll gain insights into our development, our technologies, and our production—right here at our facility in Cham. Take this opportunity to meet our team in person and get a behind-the-scenes look at Swiss electricity meter production.
Please select your preferred visit times and register using the online registration form by May 30, 2026. Space is limited to 15 delegations. We look forward to welcoming you to Cham and to a pleasant and enjoyable time together.
Severin Fischer founded Semax AG on January 26, 2011, and today he and his nearly 100 employees are celebrating the company's 15th anniversary.
The foundation stone for Semax AG was laid in 2015 with the partnership with Elster Honeywell as our distribution partner in Switzerland. This partnership had a decisive influence on our early years. Our first phase of growth was characterized by personal service, commitment, and on-site calibration of these products.
Just in time for the referendum on the Energy Strategy 2050, we launched our measuring systems in 2017, including the now highly successful and well-established Amera HES. Another milestone followed with the Ensor electricity meter, which was launched on the market in 2021 to mark the 10th anniversary of Semax AG and, with its precision and modularity, is perfectly suited to the Swiss electricity market.
Bold investments and forward-looking decisions, such as setting up our own electronics manufacturing facility, have made us robust and able to deliver even in challenging times, such as the component and coronavirus crises.
15 years of Semax AG – a teenager on the path to adulthood. With our sights set on the future and the reorganization in 2026, we are starting our anniversary year full of confidence.
Well-equipped to face new challenges, we look forward to the future with enthusiasm and would like to thank our loyal partners and customers for their trust and for the very pleasant and valued cooperation.
