Redeia Infraestructuras de Telecomunicación

What Redeia Infraestructuras de Telecomunicación does

Redeia Infraestructuras de Telecomunicación, S.A. (trading as Reintel) is a Spanish private company and subsidiary of Redeia, established in 2015 to commercialise dark fibre optic infrastructure originally developed by Red Eléctrica since 1997. The company owns and operates the largest neutral dark fibre network in Spain, comprising over 54,000 km of fully interconnected fibre and 1,457 sites (923 on the high-voltage electricity transmission grid and 534 on the conventional long-distance railway network managed by ADIF since November 2014). Coverage extends to all 50 Spanish provinces including peninsular and island territories, with international interconnection links to France, Portugal, Morocco, and Andorra, plus a submarine link between Sagunto and Mallorca connecting the Balearic archipelago. A 24x7 Network Operations Centre (Centro de Supervisión de Telecomunicaciones) monitors the entire network.

Reintel monetises its infrastructure through four product lines: Red Troncal (Backbone Network) providing long-distance fibre pair leases via transfer of right to use or multi-year lease; Cable Dedicado (Dedicated Cable) offering capillarity and access solutions connecting Points of Interconnection; Alojamiento de Equipos (Equipment Housing) leasing co-location spaces and shelters with redundant power and remote monitoring; and Soluciones a Medida (Customised Solutions) for bespoke multi-site and on-demand projects. Pricing is fully quote-based and not publicly disclosed. The go-to-market is direct enterprise sales via a specialised sales department, targeting telecommunications operators (primary), local operators and public administrations, and international operators.

The company is headquartered in Alcobendas, Madrid, and is owned 51% by Redeia (Redeia Corporación S.A.) and 49% by Rudolph Bidco S.à r.l., an entity associated with Kohlberg Kravis Roberts and Co. (KKR), following a ~$1.1 billion minority investment in December 2021. Reintel also provides maintenance services for Red Eléctrica's fibre optic cables and telecommunications equipment. The company holds ISO 9001 and ISO 14001 certifications audited by AENOR, operates with 11-50 direct employees, and leverages parent Redeia's operational backbone to manage its nationwide infrastructure footprint efficiently.

Direct peers

• Zayo Group: Global wholesale fiber provider with extensive long-haul and metro dark fiber networks serving carriers, hyperscalers, and enterprises. Closest international peer by ownership model and customer profile (wholesale dark fiber, wavelengths, IRU-based leases).
• RETN: European independent network operator providing IP transit, dark fiber, and wavelength services across pan-European routes. Comparable as a wholesale carrier-of-carriers fiber operator with international cross-border routes similar to Reintel's Iberian gateway.
• Colt Technology Services: European B2B-focused network operator with owned fiber infrastructure spanning major European business hubs. Comparable wholesale dark fiber and dedicated capacity offering to carriers and enterprises.
• Lyntia Networks: Spanish wholesale dark fiber operator offering nationwide fiber infrastructure to telecom operators and enterprises. Most direct comparable in Spain, competing on dedicated cable, metro access, and backbone routes.
• euNetworks: European wholesale fiber infrastructure operator owning and operating dense metro and long-haul networks across Western Europe. Direct comparable business model (carrier-of-carriers dark fiber and wavelength services) at broader European scale.

Others

• Cellnex Telecom: European telecommunications infrastructure operator focused on passive mobile towers, DAS, and edge nodes. Adjacent infrastructure model with similar institutional Spanish backing; could emerge as a complementary site-hosting peer for Reintel's equipment housing sites.

Broad incumbents

• Telefónica (Spain): Dominant Spanish incumbent telco with extensive proprietary FTTH and backbone fiber footprint. Both a major Reintel customer and a competitor that offers dark fiber and wholesale capacity within its own network portfolio.
• Orange Spain: Second-largest Spanish telco with substantial FTTH and metro fiber assets. Serves overlapping enterprise and wholesale customers while competing with Reintel on certain dedicated cable and metro routes.
• MasOrange (MasMovil + Orange Spain): Major Spanish converged operator resulting from the Orange-MasMovil combination, with a sizable proprietary fiber network and aggressive FTTH rollout. Represents both a significant wholesale customer and a vertically integrated competitor.
