Customer highlights
Adding value to our customers
We support our customers and their increasing demand for energy efficiency, sustainability, and automation for buildings, infrastructure and industrial sites. With one of the broadest offerings in the built environment, we deliver sustainable installations, technical services and solutions throughout the full lifecycle. Explore some of the highlights we have shared with our customers.
Solutions for data centres
Data centers are a rapidly growing part of critical infrastructure. The environmental conditions of a data center are highly controlled, with ventilation and cooling playing a significant role in their total energy consumption. Residual heat from data centers can be recovered and used in nearby buildings or district heating.
During the year 2025, Caverion Finland signed two major project contracts related to the expansion of data centers in Finland covering total technical solutions, such as electrical installations, cooling, heat recovery, ventilation, and fire safety. Nebius' data center located in Mäntsälä, Finland, was completed at the end of the year with a total capacity of 75 MW and a variety of solutions aimed at reducing environmental impact. The contract with Hyperco Fin HoldCo 1, the project company behind the Kouvola data center initiative in Finland, is one of the largest in Assemblin Caverion Group’s history.
Optimal electricity transmission and substations
The construction of transmission lines requires a high level of professionalism and strong planning skills. The Group is strongly involved in several energy sector projects and the energy transition, providing services and solutions across the entire energy chain, from planning to production and distribution.
Caverion Denmark and Assemblin Electrical (Sweden) together deliver a complete electrical infrastructure solution for Denmark’s first carbon capture plant at Asnæsværket in Kalundborg. In Sweden, Assemblin has entered a framework agreement with Sweden’s largest grid operator E.ON regarding smaller and larger project contracts at power stations within two of their energy distribution areas in Sweden. In Finland, Caverion expanded during the year its partnership with Finland's transmission system operator Fingrid by leading several major projects concerning high-voltage lines and new substations.
Trusted technical facility management partner
Most of a property’s costs and emissions incur during the operations phase. Keeping operational costs to a minimum without sacrificing the building’s end-user experience is key to optimizing the value of the property.
In 2025, Caverion signed a five-year agreement with VELUX Group, covering technical facility management services for all VELUX facilities in Denmark. The performance-based contract includes technical facility management, security, remote and advisory services, project management, and Caverion SmartView, a digital customer platform. Caverion will also support VELUX in working towards its sustainability goals.
Caverion is also responsible for the technical facility management of Stockholm Exergi’s properties. The four-year assignment started in February 2026 and may be extended by up to another four years. The assignment covers supervision and maintenance, with a focus on operational reliability, cost awareness, and sustainable property management across more than 50 properties in three regions of Stockholm.
Solutions for defense and security facilities
Geopolitical tensions and evolving national security priorities in Europe have put the defense industry into the spotlight in recent years. High-security environments, such as military bases, require advanced building technologies and specially trained personnel.
The new barracks in Villach, Austria, is one of the largest construction projects commissioned by the Austrian Ministry of Defense, with new buildings covering 81,000 m² and accommodation for 1,052 people, as well as office space for around 260 workplaces. Caverion provides the heating, ventilation, sanitary, cooling and automation systems for the project.
The capacity of prisons and detention facilities in Sweden is set to increase from 10,000 to 27,000 by 2030. Assemblin Electrical supports the Swedish Prison and Probation Service with installation work in around ten projects to build new and renovate existing facilities. It also delivers service and on-call operations for all facilities nationwide.
Reliability for critical infrastructure
We are industry experts in ensuring the reliability and efficiency of critical infrastructure with comprehensive services during its whole life-cycle, from design to maintenance. Our own professionals as well as smart and sustainable solutions support essential parts of the critical infrastructure like tele communications, energy production and distribution, ensuring optimal performance, security and resilience.
Caverion secured a five-year agreement with Telenor Towers Norway for the technical maintenance and operation of selected sites. The contract, with an option to extend for three more years, covers crucial systems like emergency power and cooling, and ensures a seamless transition with thorough quality checks and employee training.
