Arteche, a global leader in equipment and solutions for the electricity sector, has reached an agreement with AURELIUS Private Equity Lower Midmarket to acquire 100% of SEG Electronics, a German company specializing in medium-voltage protection relays for electricity networks. The transaction, which includes SEG Electronics GmbH (Germany) and its subsidiaries in the United States and the United Arab Emirates, is fully in line with the Group’s strategic roadmap and strengthens its value offering in the transmission and distribution network automation business, amid an energy transition that demands smarter and more connected networks.
Based in Kempen (North Rhine-Westphalia, Germany) and founded in 1969, SEG is an independent manufacturer of medium-voltage protection relays with over 55 years’ experience and an international commercial presence in more than 80 countries, serving a customer base of over 350 clients and employing 80 staff. SEG currently operates from a centralized production facility in Germany, complemented by sales and procurement hubs in the United States, Poland and the Middle East.
The integration is designed to generate technological synergies, combine the teams’ capabilities and expand the Group’s commercial reach in growth segments, particularly in the data center market, which requires highly reliable, stable energy infrastructure capable of withstanding high levels of demand. In this regard, SEG’s solutions expand Arteche’s commercial reach in a critical technology market with strong growth prospects for the coming years, as they strengthen its offering in electronics and automation.
As such, SEG’s protection solutions bolster Arteche’s offering in market segments that are key to the evolution of energy networks. As a result of this transaction, Arteche also strengthens its presence in Central Europe and gains a more solid foothold in the DACH region (Germany, Austria and Switzerland), a strategic market given its industrial and energy significance.
According to Alexander Artetxe, CEO of Arteche: “The acquisition of SEG is fully in line with our strategy and reinforces a key pillar of our Strategic Plan: the automation and digitalization of energy networks. We are bringing together technology, talent and proven expertise to complement the strong capabilities of our team, the very team that has made us world leaders in auxiliary relays. In turn, the SEG team, with its technical expertise and track record in digital protection, provides a solid foundation for accelerating our roadmap and expanding our commercial reach in one of the fastest-growing and most significant markets for the coming years.”
Moving forward with the inorganic agenda of the ‘Energizing Futures Together’ Strategic Plan 2024–2026
The acquisition of SEG, with an equity value of €50.6 million, forms part of the inorganic growth strategy set out in Arteche’s 2024–2026 Strategic Plan, “Energizing Futures Together”, which aims to identify opportunities to expand into new geographical markets, incorporate cutting-edge technologies and open the company up to new market segments. In this way, Arteche is specifically strengthening its automation pillar, expanding its technological reach and accelerating the Group’s capacity to develop integrated distribution solutions.
Along the same lines, Arteche announced last March that it had acquired a 35% stake in the Navarre-based company Uptech Sensing, which specializes in the development of distributed optical sensors and smart monitoring systems. This strategic investment strengthened its transmission and distribution grid automation business, as well as its position at the forefront of optical sensor technology, digitalization and smart asset management.
Furthermore, in October 2025, Arteche entered into a strategic partnership with Elewit, Redeia’s technology platform leading to the creation of Arin Technologies, a new company specializing in the development of advanced software for the electricity sector, established with the aim of accelerating the automation, digitalization and visualization of electricity infrastructure.
