MADRID, November 11, 2026 – ACS Group, through its subsidiary DRAGADOS, has agreed to acquire 100% of Voltan Group from majority shareholder Henko Capital Partners, strengthening its capabilities in energy infrastructure, power transmission and distribution, and industrial services.
The acquisition will add specialised expertise in electromechanical installations, commissioning, operations and maintenance, supporting ACS Group’s strategy to expand into high-value-added activities and deliver integrated solutions throughout the project lifecycle.
The transaction will strengthen the group's position in power infrastructure by adding experience in transmission and distribution projects, established relationships with major grid operators and technical qualifications for participation in regulated projects.
Voltan Group's capabilities will complement ACS Group's existing international operations and create opportunities for collaboration across its businesses and geographic markets.
In the energy sector, the acquisition will add expertise in turbine installation, commissioning and operations in Europe. It will also support opportunities in combined-cycle power generation projects and strengthen ACS Group's ability to participate in conventional nuclear project packages alongside qualified partners.
The expanded capabilities will also enhance the group's mechanical, electrical and instrumentation services for digital infrastructure projects.
ACS Group CEO and HOCHTIEF CEO Juan Santamaría said the acquisition would strengthen the group's presence in strategic energy and infrastructure sectors by adding a specialised platform and an experienced workforce to its international operations.
Founded in 2021, Voltan Group comprises several companies providing technical and engineering services for the energy sector, with more than 45 years of combined experience. Its operations are organised around two primary business areas: Energy and Transmission & Distribution.
The company expects to generate approximately €150 million in revenue in 2026 and employs more than 1,200 professionals. Its international operations span the United Kingdom, Germany, Peru, the Netherlands, Portugal and Belgium.
The transaction remains subject to competition clearances and other customary regulatory approvals.
The acquisition expands ACS Group's access to specialised engineering, electrical and power infrastructure expertise at a time when energy networks, generation facilities and digital infrastructure require increasingly integrated technical services. Combining Voltan Group's capabilities with DRAGADOS' international project delivery operations could strengthen the group's ability to pursue complex energy and industrial infrastructure projects across multiple markets.
