FLOW BUSINESS
Recurring activities involving the design, installation and maintenance of electrical and mechanical infrastructure, as well as control systems, made up 55% of Cobra IS’s business in 2025.
Reflecting the rapid growth of the segment, Cobra IS has started construction of the social security data centre in Soria, Spain.
In 2025, Cobra IS renovated and maintained the aboveground and underground telecoms networks for several electricity distributors in Spain, and deployed 5G communications for the Albacete–Alicante and Barcelona–Figueres high-speed rail lines, continued to install and maintain landline networks, and delivered turnkey fibre optic networks in several Spanish provinces.
Data centre business continued to grow, with Cobra IS expanding its position in this market by working with major hyperscalers and leading global technology companies in Chile, Uruguay, the United States, Spain and Portugal. The company is currently delivering high-value, mission-critical projects, including the construction and commissioning of several data centres in Madrid, the design and construction of a 27 MW facility in Germany for a leading US-based operator, and the development of a large data centre campus in Zaragoza with a planned capacity of 300 MW. It is also building specialised public sector infrastructure, notably including the social security data centre in the Spanish city of Soria, leveraging its expertise across the entire data centre value chain from civil engineering to electromechanical installation and fit-out.
Cobra IS’s industrial maintenance projects included, for Moeve and Apical, launching the comprehensive mechanical, electrical and instrumentation assembly of the Process (ISBL) and Interconnection (ITX) units for the largest second-generation biofuel plant in Southern Europe. The facility will produce an annual 500,000 tonnes of sustainable aviation fuel and renewable diesel from agricultural waste and used cooking oil. Also for Moeve, Cobra IS began the final building and piping assembly of the first isopropyl alcohol production plant in Spain that will run on green hydrogen. In Asturias, it is dismantling the La Pereda thermal power station for its conversion into a biomass plant that will consume approximately 350,000 tonnes of organic feedstock per year.
In the railway sector, Cobra IS completed the renovation of the communications and control systems for a section of the Palencia–Santander line, commissioned new EiS23 interlocking for a freight logistics hub and the suburban Atocha–Guadalajara line, and finished electrifying a section of the Madrid– Extremadura high-speed rail line.
Cobra IS continues to provide public lighting and traffic control maintenance services, and maintains and operates technical equipment on more than 11,500 km of Spain’s government-owned national, regional, provincial and local roads. Over the next four years, the Sidera Analytics system will be deployed across the national road network to collect, integrate and analyse multi-source data. After winning the maintenance contract for Calle 30 in Madrid, Cobra IS installed navigation beacons in the motorway’s 48 km of tunnel sections, providing users with uninterrupted access to applications such as Waze or Google Maps.
In Portugal, Cobra IS is working to double the capacity of the Pico Vermelho geothermal power plant, bringing it to 12 MW, which will significantly increase the production of electricity from renewable sources on the island of São Miguel.
In Germany, Cobra IS has begun the mechanical and piping works for a direct reduced iron plant, which will be the first to run only on green hydrogen, avoiding the emission of 3.5 million tonnes of CO2 per year.
Cobra IS remains very active in the Americas. In Brazil, it now operates and maintains 40,000 km of transmission lines, up from 30,000 km in 2024. In Argentina, it completed 50% of the mechanical and electrical assembly of 56 wind turbines (336 MW) at La Flecha, one of the largest wind farms in the country. In Mexico, it will deliver 12 high-voltage electrical infrastructure works packages for Amazon. In Chile, it is carrying out the extension of metro Line 6 in Santiago, which will improve service in the west and reduce travel time for 90,000 users. In Puerto Rico, Cobra IS finished replacing conventional motorway toll plazas with a new system using free-flow technology. In the United States, it was awarded a contract to install lighting and systems to prevent wrong-way driving on two motorway sections in Dallas (Texas).
In Saudi Arabia, Cobra IS is finalising the construction of three substations, in Qurinayh (110/13.8 kV), Al-Khair (132/13.8 kV) and Jameen (110/13.8 kV), and commissioned two projects, Wadi Al Safar 8238 (132/33 kV) and Wadi Al Safar 8239 (132/33 kV).
Lastly, in Southeast Asia, Cobra IS began installing operating suites, intensive care units and stateof- the-art diagnostic imaging equipment for four hospitals in Indonesia.
