Telefónica Data Centre

Telefónica’s Data Centre in Alcalá de Henares (Madrid) is one of the largest data processing centres in the world. This Data Centre carries out system transformation for Telefónica in Europe and provides hosting and housing services for its clients. Ferrovial Services is responsible for the maintenance and operation of this technological facility.

  • 23 I.T. rooms
  • 681 m2 each one
  • 50 mW Installed Power
  • 7 IT Halls


The Tecnoalcalá Data Centre Project built by Ferrovial Agroman for Telefónica is one of the four largest data processing centres in the world (CPD) and is located at the Tecnoalcalá Technology Park in Alcalá de Henares, Madrid.

This project, which was developed in five phases and designed by the Engineering Department, comprises 23 server rooms, each 681 m2 and designed in line with basic concepts of modularity, flexibility, redundancy and efficiency. It has LEED Gold certification from the Green Building Council and was designed to meet the highest reliability standards set out in the Uptime Institute’s TIER IV certification, which ensures that the centre offers the greatest possible security and redundancy.
Its design, construction and operation conform to the highest standards of sustainability, notably reducing water and energy consumption and CO2 emissions with respect to traditional data centres.

Efficiency criteria for the construction

Ferrovial Agroman has been working on the building of a data processing centre with the essential criteria in design being efficiency, given the significant consumption in terms of energy from such facilities. Following strict sustainability criteria, the project will work on the following:

  • Design strategy with cold/hot corridor within the IT room.
  • Low energy consumption of AC equipment, using outside air as far as possible for cooling.
  • Temperature control through direct outside air and/or adiabatic cooling in the IT rooms for 92% of hours over the year.

It should be pointed out that this DPC has one of the best energy consumption profiles compared to other similar centres currently in operation. Moreover, the PUE (Power Usage Effectiveness) is under 1.3, compared to an average of 2.2, thus generating energy savings of 40% (and up to 75% in terms of manageable energy consumption).

  • Under 1.3 PUE (Power Usage Effectiveness)
  • 40% Energy savings
  • 75% Manageable energy consumption

Ferrovial Services

The Ferrovial Services project for this data processing centre is based on criteria of sustainability in operation, optimising energy efficiency and ensuring maximum availability of facilities in line with the critical nature of this infrastructure. A unique feature of the contract is that the company guarantees a specific PUE (Power Usage Effectiveness) value for the data centre according to different levels of workload, in such a way that Ferrovial Services will bear any additional energy costs where the PUE goes above the values agreed in the contract, whereas any savings arising from improved performance of the facilities, and therefore a better-than-agreed PUE value, will be shared with Telefónica.

Facility Management with guaranteed energy efficiency

In addition to energy management, the Ferrovial Services proposal includes a Facility Management project to cover maintenance of all infrastructures within the data centre to exacting levels of service linked to the availability of facilities, as well as traditional services such as cleaning, gardening or passive and physical safety and security.

Cutting-edge technology

In order to optimise operation of the data centre, Ferrovial Services has put in place various innovative systems and tools, some of which are:

  • The Data Centre Infrastructure Management (DCIM) tool, to analyse the dynamic performance of the IT halls.
  • The Building Management System (BMS), which acts as the “brain” of the data centre and is a critical element of Ferrovial Services’ operation and energy management. With over 40 000 control points within the facility, it can provide an immediate response to any incident that might arise.
  • Computerised Maintenance Management System (CMMS) tool, which communicates in real time with the BMS to set work orders for corrective maintenance, and is also the basis for managing preventive and predictive maintenance within the data centre.

A certified model of excellence

Ferrovial Services has obtained the Operational Sustainability TIER IV Gold award from the Uptime Institute for Telefónica’s data centre in Alcalá de Henares, the highest certification for sustainability in operation. This is the first data centre to obtain such award outside North America, and the third on a global level, making it an international benchmark.
