The largest data center in the Baltic countries has been opened – the energy efficient data center utilises Siemens' technology

The largest and most energy efficient data center in the region was opened on Feb 17, 2022 in Estonia. The building that cost nearly 40 million euros is the first of the three buildings to be built in the same area, all of which will contribute to the development of the Baltics’ e-commerce and digital societies. Siemens has been the technology partner of Greenergy in the data center project.

To the ordinary citizen, the new data center means a smaller ecological footprint of data, and even better access to e-services. In addition, the opening of the building complex will multiply the data hosting export potential of the region.

Data centers are the physical foundation of our current and future digital society, without which our way of life and business activities would be unthinkable. Greenergy’s top-tier and high energy efficiency data center will increase the competitiveness of the Estonian economy and will create the necessary infrastructure for the digital transformation.
said the Minister of Entrepreneurship and Information Technology Andres Sutt after participating in the opening.

According to him, up until now, there was no such high-level digital infrastructure in Estonia, and the new data center will remarkably increase the competitiveness of the companies of this area. It will also create favourable conditions for foreign companies to offer their services on the Estonian or Baltic market.


Founding the Greenergy Data Centers took more than five years to get from its inception to opening, and experts from six countries participated in the process.


“The complex opened today conforms to all of the highest international security standards and aims at 25% higher energy efficiency than the market’s average,” said the author of the idea to create the data center, Kert Evert.


“Technologically speaking, we are at the absolute top of the world.”


The first building, opened today, spans 14,500 square metres. The total planned capacity of the complex is 31.5 MW – in other words, the center’s electrical connections could cover the energy needs of a smaller town.


As the technology partner of the project Siemens delivered the solution for the electrification in the medium and low voltage with busbars to ensure reliable and safe power supply. In addition, the company has delivered a modern energy management solution. An integrated, large-scale and modular system suite optimizes energy use based on artificial intelligence, ensures the right conditions for servers, secures and monitors electricity distribution such as operation, quality and reliability and increases efficiency throughout the lifecycle, and minimizes the environmental impact of the data center.


"The need for smart infrastructure solutions is growing as data is required and used more and more to increase efficiency, flexibility, speed and quality. This is Siemens Osakeyhtiö’s largest technology partnership in the area of data centers. Similar solutions can be delivered to very different needs and different sizes," says Jussi Mäntynen, Head of Electrification and Automation Business Nordic & Baltic, Siemens Osakeyhtiö.


Since the data center must be prepared for the unexpected and always function, every important support system of the complex is duplicated. In some places, back-up systems have their own back-up systems.


The Three Seas Initiative Investment Fund provided funding for building the facility.
