ACS Group strengthens its industrial and energy capabilities through the acquisition of Voltan Group

ACS Group has reached an agreement, through DRAGADOS, with Henko Capital Partners, the majority shareholder of Voltan Group, to acquire 100% of the company. The transaction strengthens ACS Group’s industrial and energy capabilities through the addition of a specialized platform with expertise in power transmission and distribution, electromechanical installations, commissioning, operations and maintenance.

The acquisition is aligned with ACS Group’s strategy to expand its capabilities in high-value-added activities and provide increasingly integrated solutions across the full project lifecycle, from engineering and construction through commissioning, operations and maintenance.

The addition of Voltan Group will further strengthen ACS Group’s position in energy and power infrastructure, adding a platform with extensive experience in transmission and distribution projects, established relationships with leading grid operators and the technical qualifications required to participate in regulated projects. These capabilities will complement ACS Group’s existing international activities in this market.

Voltan Group’s specialized expertise and services will also be available across different ACS Group businesses and geographies, creating opportunities for collaboration and growth. In the energy sector, the transaction will add capabilities in turbine installation, commissioning and operations in Europe, support opportunities in combined-cycle power generation projects and strengthen the Group’s ability to participate alongside qualified partners in conventional packages for nuclear projects. It will also enhance ACS Group’s mechanical, electrical and instrumentation capabilities for digital infrastructure.

A specialized platform with an international presence

Founded in 2021, Voltan Group comprises several companies specializing in technical and engineering services for the energy sector, representing more than 45 years of combined experience. The Group operates primarily across two business areas: Energy and Transmission & Distribution.

Voltan Group expects to generate approximately €150 million in revenue in 2026, employs more than 1,200 professionals and has an international presence in markets including the United Kingdom, Germany, Peru, the Netherlands, Portugal and Belgium. 

The transaction is subject to the relevant competition clearances and other customary regulatory approvals.

Juan Santamaría, CEO of ACS Group and HOCHTIEF, said: “The acquisition of Voltan Group strengthens our strategy of expanding ACS Group’s capabilities in high-value-added activities and further enhances our position in strategic sectors linked to energy and infrastructure. We are adding a highly specialized platform and an experienced team whose expertise complements our global capabilities and will enable us to provide increasingly integrated solutions to our clients.”
