A group of people in a data center discussing green energy.

The Baltics’ greenest and largest facility

Greenergy operators partnered with Siemens to develop the largest, most secure and most sustainable data center in the Baltics. As the lead contractor, Siemens helped deliver a green facility that combines world-class reliability, security and connectivity with exceptional growth potential.

Running a data center the green way

When Greenergy operators partnered with Siemens in 2021, their goal was ambitious: to create a data center that offers the highest levels of reliability, security and sustainability; a data center that has world-class connectivity and growth potential. All this with a single-vendor approach in mind. With a coherent technological concept as well as cutting-edge hardware and software, Siemens became the lead contractor for the largest, most secure, and greenest data center of the Baltics.

Key Facts:

Location: Tallinn, Estonia
Project duration: January 2021–February 2022

Leading AI, sensory and high-voltage innovations

Discover AI-driven cooling optimization

Siemens improved energy use with the AI-powered White Space Cooling Optimization (WSCO) system to automatically adjust cooling based on demand.

Count on infrastructure reliability

Siemens ensures reliable power supply with three lifelines: Sivacon 8PS busbars, Simosec medium-voltage switchgears and Siemens Energy high-voltage system.

Rest assured with safety measures

The Greenergy data center complex has over 3,000 infrastructural and environmental sensors, monitored on a 24/7 basis for maximized safety.

Cool down on energy demand

Temperature management is a major source of energy use in data centers. Siemens optimizes it with an AI-supported White Space Cooling Optimization (WSCO) system. When demand increases, it reacts automatically, adjusting units and airflow to match the load requirements. Data center managers control the system and facility via Desigo CC BMS. In addition, Power Manager, the latest extension module to Desigo CC, visualizes the electrical infrastructure of the data center with dashboards, providing real-time and historical data for reporting, trending, analysis, alerting, and KPI monitoring.

Three lifelines for maximized infrastructure reliability

Sivacon 8PS busbars and Simosec medium-voltage switchgears as well as a Siemens Energy high-voltage system ensure Greenergy’s reliable power supply. In addition, the substation and the plant’s transformers are connected via two redundant links. If, against all odds, both connections fail, the Uninterruptible Power Supplies (UPS) activate. Should even this measure be affected, another lifeline exists: on-site generators power the system for up to three days without any external energy requirement.

Thanks to this elaborate safety concept, the facility achieves level three to four on the scale of infrastructure redundancy.

The safest datacenter in the Baltics – for 3,000 reasons

The building complex has over 3,000 infrastructural and environmental sensors, monitored on a 24/7 basis. Each server room is equipped with its own oxygen reduction fire prevention system which works in conjunction with a very precise smoke detection system to detect any fire instantly. Additionally, all technical rooms are designed as separate fire protection zones.

Our single-vendor approach and the ‘German Engineering’ seal of quality convinced us of Siemens as a supplier – a decision that has absolutely paid off in the course of the project.
