The document describes a former military communications center near the town of Vrátkov, approximately 25 km from Prague, that has been reconstructed to serve as an underground data center complex. The site has a total area of 7,200 square meters spread across two underground floors, with space for up to 4,200 square meters of IT equipment. It has redundant power supplies capable of delivering up to 15 MW of electricity. The site also has fiber optic connectivity and infrastructure to supply water and manage waste water. The location provides easy access to major transportation routes and a large potential customer base.

Town of Vrátkov
The future data centre is situated near Vrátkov, a town approx.
25 km (~15.5 miles) away from the capital’s ring road, which
enables an easy access to a wide potential clientele of top
multinational companies and leading domestic firms, IT specialists as
well as to an international airport. D1 motorway connecting Prague
with the second most populated city of Brno is located less than
20 km (~12.5 miles) from the data centre and further facilitates
a connection with the third most populated city of Ostrava, Bratislava
(the capital of Slovakia) and Vienna (the capital of Austria).
Executive Summary
• Former military communications centre near the town of Vrátkov, approx. 25 km (~15.5 miles) from Prague.
• The site benefits from underground premises with 7,200 m2 (~77,500 sq ft) of total space, backbone connectivity and
a use permit for future data centre operation.
• The total net ICT area / racks distribution is
up to 4,200 m2 (~45,000 sq ft) depending on
final layout and used technology efficiency.
• The newly-reconstructed facilities provide
the highest security and are able to meet the
strictest demands of potential customers.
• The premises offer the possibility of connecting
to the networks of Backbone operators within
a distance of 1 to 6 km (~0.8-3.5 miles).
• Two independent sources of high voltage
electricity supply providing sufficient capacity
- power options of 15 MW.

5. Electricity Supply and Power Capacity
• Total high voltage 22 kV power options amount to 15 MW,
• Existing transformers of 630 kVA (3x) and 1,000 kVA (3x),
• Two independent sources of HV electricity supply,
• Dedicated space for three diesel generators.
• Power capacity of future data centre of up to 8,750 kW,
• Power density of up to 2,083 W/m2 (~192 W/sq ft)
(based on space utilisation and power of servers).
Existing Technology Overview
Underground Facilities
• Total area of 7,200 m2 (~77,500 sq ft) on two floors
• Each floor has approximately 3,600 m2 (~38,750 sq ft)
• Total net ICT area of up to 4,200 m2 (~45,000 sq ft)
(based on final layout and used technology efficiency)
• Newly-reconstructed premises designed to maximise
open space capacity (only bearing walls left in place)
• Existing ventilation to make the facilities inhabitable
• Shafts available for equipment manipulation
• Use permit for data centre operation secured
• Expansion potential to other buildings within the site
Water Supply and Waste Water Management
The site has its own water source, which is also used to supply
two neighbouring towns (Vrátkov and Český Brod). A water
control unit placed in the underground facilities (-2nd floor)
serves to supply the entire site and the town of Vrátkov.
For the purpose of waste water management, there is
a sewage treatment plant located just outside the site. The
capacity of the plant suffices for the operation of the office
building and dormitory.
Optical Networks
The premises are strategically located. The Telefónica O2
backbone network leads directly acrossas highlighted in the
attached picture.
The maximum data throughput is 10 Gb/s. Networks of
other providers lie in the following distance from the site:
Dial Telecom: 1,200 m (~0.8 miles),
Liberty Global (UPC): 3,800 m (~2.4 miles),
ČD-Telematika: 5,600 m (~3.5 miles).
All of the above optical networks belong to the long-
distance category with the highest possible capacity.
