Future Market of Electrical Engineering: Strong Perspectives

The Swiss market for electrical engineering and new energies is undergoing structural change. The rapidly growing data centre market in particular is evolving into a central driver of demand for powerful and highly available energy infrastructure.

Data centres impose the highest demands on supply security, network stability, redundancy, and energy efficiency. At the same time, sustainable integration into existing power grids is increasingly coming into focus.

In parallel, electromobility and battery storage solutions are driving further growth in the market. The increasing complexity of technical infrastructures requires integrated solutions from a single source – from planning through installation to operation.

Given these developments, the integration of Pfanner & Frei AG and re.com Elektroanlagen AG enhances TSG Group's technical competence and operational capacity in Switzerland. It expands the project resources and deepens the know-how, especially in demanding electrical engineering applications.

It enables TSG Switzerland SA to further consolidate its position as a comprehensive provider in energy and infrastructure solutions, strategically aligning seamlessly with the TSG Group’s direction by expanding relevant competencies.

A Strategic Direction for the TSG Group

With this acquisition, the TSG Group strengthens its market position in the DACH region and consistently pursues its goal of becoming a leading player in the energy transition.

This merger is part of an ambitious international growth strategy, with over 45 acquisitions in 20 countries within four years. The group achieved annual sales of around 1,400 million euros in April 2025, employs more than 7,000 people, and is active in 30 countries across Europe and Africa.
