Assemblin expands in power supply and high voltage through acquisition

Assemblin is increasing its expertise in power and high voltage through the acquisition of Kraft och Elpartner in Västmanland AB (“Kraft och Elpartner”) with some ten employees in the Swedish province of Västmanland and annual sales of about SEK 20 million.

Kraft och Elpartner, which was founded in 2018, has offices in Västerås but operates throughout Västmanland. The company has extensive experience of working with high-voltage facilities in project format, or through operation and maintenance assignments, although the company also performs service assignments and projects in more traditional electricity electrical engineering. Kraft och Elpartner is distinguished by its strong focus on sustainable development and on safeguarding established traditions in electricity and power.

“We are very happy to be able to welcome Kraft och Elpartner to Assemblin. Kraft och Elpartner is a niche company on the power side with extensive expertise in high voltage, which complements our electricity operations in terms of both expertise and customers. This acquisition allows us to take on more types of assignments,” says Fredrik Allthin, President and head of the Assemblin Electrical business area.

Kraft och Elpartner was started by Martin Liljeros, who today is the company’s main owner and CEO.

“For us at Kraft and Elpartner, sustainability, quality and expertise are our core, and when we were now considering a new ownership solution, finding a partner with the same priorities was absolutely critical. Assemblin’s technology-oriented organisation and ambitious aspirations were therefore crucial, and we look forward to continuing to grow as part of Assemblin,” says Martin Liljeros, CEO of Kraft och Elpartner.
