Tensor Estate Takes Stake in Greenergy Data Centers Owner, Investment to Fuel AI-Driven Expansion

Real estate and infrastructure investor Tensor Estate has acquired a stake in MCF Group Estonia, the owner and operator of the Greenergy Data Centers facility near Tallinn, Estonia, in a move that underscores the accelerating demand for digital infrastructure to support artificial intelligence workloads. The investment will provide expansion capital for the Estonian data center to scale its capacity in response to surging AI requirements.

Greenergy Data Centers, launched in 2022, is the first digital investment of the Three Seas Initiative Investment Fund (3SIIF). The development was originally announced in 2015 and was initially planned to comprise three buildings. The facility has since become a strategic asset within the region’s emerging data center landscape, positioned to serve the growing needs of AI and high-performance computing.

As part of the transaction, 3SIIF remains the majority shareholder of MCF Group Estonia. A joint supervisory board has been established with representatives from both 3SIIF and Tensor Estate, while day-to-day operations will continue under the existing management team. The companies said the capital infusion is directed specifically at expanding the facility to meet escalating demand fueled by the artificial intelligence market.

“We welcome Tensor Estate as a new shareholder in MCF Group Estonia,” said Cameron Cook, senior investment director at Amber Infrastructure, investment adviser to 3SIIF. “As the majority shareholder, 3SIIF remains fully committed to supporting the continued development of Greenergy Data Centers. The ongoing expansion of the data center in response to unprecedented demand from the artificial intelligence market is underway, and we look forward to the full commercialization of this strategically important digital infrastructure asset.”

Kert Evert, CEO of MCF Group Estonia, added: “We have been developing the infrastructure for years with a long-term perspective. Tensor joining us supports our long-term growth objectives.”

The deal highlights a broader trend of institutional and infrastructure capital flowing into European data center projects, particularly those positioned to capture AI-related compute demand. With AI workloads requiring increasingly dense power and cooling configurations, facilities like Greenergy Data Centers that are built with expansion in mind are attracting investor interest. The partnership also signals the continued maturation of the Baltics as a regional data center hub, leveraging connectivity to Nordic and Central European markets.
