JARO Groep, backed by FIELDS Group, acquires Van Hoek Bouw to enhance high-voltage infrastructure capabilities in Dutch energy transition.
JARO Groep B.V., a leading Dutch infrastructure specialist, has acquired Van Hoek Bouw B.V., a contractor focused on high-voltage foundations and transformer station construction. Supported by investor FIELDS Group, this acquisition, announced on June 11, 2026, aims to strengthen JARO Groep’s role in the energy transition by expanding its expertise in complex energy infrastructure projects.
While the financial terms of the deal remain undisclosed, JARO Groep has taken full ownership of Van Hoek Bouw, marking its fifth acquisition since March 2024. The transaction consolidates JARO Groep’s multidisciplinary service offering, particularly in the high-voltage segment of the energy infrastructure market.
JARO Groep operates across several civil engineering disciplines, including earthworks, green landscaping, energy infrastructure, and environmental projects. The group’s broad portfolio now integrates Van Hoek Bouw’s specialized capabilities in designing and constructing high-voltage foundations and transformer stations, which are critical components in the Dutch energy grid.
Van Hoek Bouw, based in Zwolle, serves a niche market characterized by high technical complexity and stringent safety standards. Its client base includes major grid operators and contractors such as TenneT, Enexis, Qirion, SPIE, and Omexom. Founder Rob Dellen highlighted the strategic fit, stating, “After years of strong growth, we see JARO Groep as the right partner for the next phase. By joining forces, we can further strengthen our position and respond optimally to the growing demand driven by the energy transition.”
JARO Groep’s CEO, Marloes Kooijmans, emphasized the strategic rationale: “With Van Hoek Bouw, we are adding specialist expertise in high-voltage foundations that fits perfectly with our strategy in the energy transition. The combination of technical expertise, strong client relationships, and an excellent safety track record makes Van Hoek Bouw a valuable addition to the group.”
Management team member Gerrit Kalkman added that the acquisition enables a more integrated approach to projects, stating, “By combining this expertise with our existing activities in the energy transition, we can take a more integrated approach to projects and further unburden our clients.”
FIELDS Group, the lead investor supporting JARO Groep, focuses on developing companies with growth potential in the Benelux and DACH regions. Fabianne Onderwater of FIELDS Group noted, “This acquisition marks another important step in building JARO Groep into a leading national player, with entrepreneurship, craftsmanship, and customer focus remaining at the core.”
The deal reflects broader industry trends where infrastructure companies are consolidating to meet increasing demand for energy transition projects. The integration of Van Hoek Bouw’s high-voltage construction expertise enhances JARO Groep’s ability to bid for larger, more complex contracts and deliver multidisciplinary solutions.
Operational synergies include shared procurement efficiencies, streamlined project management, and optimized use of labor and equipment. However, integration challenges remain, such as aligning corporate cultures and maintaining Van Hoek Bouw’s specialized safety standards.
Looking ahead, JARO Groep plans to leverage this acquisition to scale operations and deepen client relationships in the energy infrastructure sector. The company aims to capitalize on the growing demand for high-voltage infrastructure driven by the Netherlands’ commitment to energy transition and sustainability goals.
