Metrology and Innovation Centre (CMI)


Our Metrology and Innovation Centre (CMI) was created in 1987 in Zaragoza to promote the development of new technologies for the use of natural gas, as well as to manage participation in R&D projects in all areas of the company.

Today, its objectives focus on providing metrology services to support the correct measurement of energy in Enagás and innovation services to achieve carbon neutrality and facilitate the integration of renewable gases into the Gas System.

The facilities include R+D+I activities, Enagás measurement support, the Central Laboratory and a Data Processing Centre (DPC), whose functions are as follows:


The CMI has been providing services for more than 30 years to the different areas of Enagás and to national and international companies in the natural gas and renewable gases sectors, to which it provides technological support. The Centre offers services in the following areas:


In 2013, we set up our second Data Processing Centre (DPC) or Green Data Centre, which is interconnected and synchronised with the main DPC, located in Madrid. Together they ensure the correct operation of the Gas System and the security of natural gas supply in Spain.

The Green Data Centre is the result of our efforts in innovation, striving for sustainability and support for efficiency. It was one of the first of its kind in Europe and the first in Spain to obtain LEED certification — one of the world’s most prestigious sustainable construction standards — on account of its high-performance systems that maximise energy efficiency. Thanks to these systems, the DPC consumes 30% less electricity than other centres of a similar size and emits 40% less CO2. We were also the first European energy company to obtain Tier IV certification for the high level of security of our data centre in Zaragoza.


The DPC consumes 30% less electricity than other centres of a similar size and emits 40% less CO2.


Given the importance of the facility, the building is equipped with the latest surveillance technology to ensure the protection and integrity of the Spanish Gas System’s information, both on-site and remotely from the 24/7 security facility in Madrid.


Our Central Laboratory, whose objective is to contribute to the development of new technologies to improve Enagás’ activity and the industry, has three specialised laboratories accredited by the National Accreditation Body, ENAC.

This laboratory performs calibrations of industrial, commercial and domestic gas meters or flowmeters in its different calibration benches.

This laboratory performs analysis and calibration of gas mixtures, determination of gas properties in accordance with ISO 6976, EN 16726, and the preparation, rental and dispatch of sample cylinders.

This laboratory performs calibration of instruments in the area of pressure, temperature and electrical quantities.
