TSG, the European market leader in technical services for responsible mobility solutions, is further strengthening its expertise in electricity and solar energy with the acquisition of two new companies: NRGreen ApS (Denmark) and Ruven Baumgärtner Elektrotechnik GmbH (Germany). These acquisitions form part of TSG’s strategic ambition to develop fully integrated multi-energy solutions across Europe and to strengthen its operational capabilities in order to meet customers’ growing demand for electrification.
With these latest additions, TSG has made a total of 38 acquisitions across Europe over the course of three years. These acquisitions are acting as a catalyst for the Group’s transformation and are positioning TSG as a key player in Europe’s green transition.
Strengthening expertise in electricity and solar energy across Europe
The two companies bring further technical expertise to TSG’s business areas within the electricity and solar energy sectors:
- NRGreen ApS (Denmark): Based near Copenhagen, NRGreen provides design, installation and maintenance services for solar power systems with battery storage. With a solid project portfolio and extensive experience in financing, NRGreen strengthens TSG’s ability to expand its solar energy offering in the Nordic region. The acquisition also strengthens TSG’s presence in Northern Europe – a region where electrification is accelerating significantly and new energy infrastructures are developing rapidly.
- Ruven Baumgärtner Elektrotechnik GmbH (Germany): As specialists in electrical installations with over 40 years’ experience, RBE provides design, installation and maintenance services for electrical systems in the retail sector (food and non-food), industry and the commercial sector. With strong technical expertise and a nationwide presence, the company strengthens TSG’s position in the German market and supports the expansion of its electrical business.
Strengthening local expertise to deliver integrated energy solutions across Europe
These acquisitions strengthen TSG’s ability to deliver end-to-end, responsible solutions for commercial, industrial and mobility-related infrastructure across Europe. By integrating highly specialised local teams, TSG is strengthening its operational presence and technical expertise in the fields of solar power, electrical installation, battery storage and the integration of smart systems.
TSG is a recognised expert in integrated energy services and designs, installs and maintains electrical and solar-powered systems tailored to customers’ needs, all with a focus on high quality and safety. This strengthened network of specialists enhances the Group’s capacity to deliver complex, large-scale projects – ranging from the electrification of industrial sites and commercial solar installations to upgrades to electric vehicle charging infrastructure.
Solar energy: A growing priority for operational optimisation
As electrification increases, solar energy is becoming a strategic lever for mobility operators facing growing energy challenges at their sites. Fast charging, grid constraints and new regulatory requirements are prompting more and more customers to integrate solar power systems and battery storage directly into their infrastructure. TSG’s expertise in solar energy helps these customers secure and optimise energy flows, accelerate roll-outs and achieve greater autonomy – thereby turning energy into a genuine operational asset. The latest acquisitions further strengthen the Group’s ability to deliver these solutions – wherever in Europe its customers are located.
“With these two new acquisitions, we are continuing to deliver on our strategy: to strengthen our expertise in electricity and solar energy, expand our presence in Europe and offer even more integrated solutions to support our customers” green transition. The knowledge and skills of our employees are crucial to our growth and transformation,” says Jean-Marc Bianchi, President & CEO of TSG.
