MCF Group Estonia and Caverion Finland have signed an agreement to add 22 MW of IT power and cooling to Greenergy Data Centers located in Estonia. Upon completion, the campus will provide a total of 31.5 MW of capacity.

As the main contractor, Caverion is responsible for the technical systems required for the expansion; including electrical, cooling, ventilation, and fire protection systems. The expansion of the data hall is expected to be completed in autumn 2026.

MCF Group’s data centre is the largest in the Baltic region and represents world-class technological standards. It complies with the highest international security requirements.

"The expansion of the Greenergy data centre marks the next step in developing AI-ready digital infrastructure in Estonia. Delivering projects of this kind requires experience that can only be gained by building some of the world's most complex technical facilities. Caverion brings valuable expertise from delivering similar projects across the Nordic region, making them a strong partner for this project", said Kert Evert, CEO of MCF Group Estonia.

“We appreciate the trust MCF Group Estonia has placed in our company and our experts. We are proud that Caverion’s expertise and track record in delivering technologically advanced projects have convinced international investors and developers of large industrial and data infrastructure projects. We complete projects even on tight schedules without compromising safety or quality. The expansion of the data hall at the data centre in Estonia will be carried out together with Caverion’s experts in Finland, Estonia, Latvia and Lithuania and with our partner companies in Estonian”, says Ville Tamminen, CEO, Caverion Finland, EVP.

The data centre has a broad economic impact: it strengthens Estonia’s competitiveness and position as a hub for digital infrastructure in the Baltics. The centre also creates conditions for new foreign investments. The project employs approximately 200 experts on site and will be carried out with a network of companies in Estonia.

“This contract marks a key step in our data centre strategy. As demand grows, our expertise ensures secure and reliable solutions that create real value for customers,” says Egidijus Šydeikis, Managing Director, Caverion Lithuania, who heads Caverion’s operations in the Baltics.

Caverion and its parent company Assemblin Caverion Group have a strong position as trusted partners for demanding industrial and infrastructure projects. In the data infrastructure market, Caverion is known as a technical designer and implementation partner for large, technologically advanced industrial and infrastructure projects requiring very high safety and quality standards. Caverion has participated in nine data centre projects in Finland and dozens of other technologically advanced industrial and infrastructure projects that require very high safety and quality standards.

The agreement in Estonian follows recent data centre assignments in Finland, Denmark and Sweden, showcasing the broad span of the Group’s capabilities.
