What Mégalis Bretagne does

Mégalis Bretagne is a public territorial cooperation mixed syndicate (syndicat mixte de coopération territoriale) created in 1999 under French public law, owned collectively by 59 intercommunalities, four departments (Côtes-d'Armor, Finistère, Ille-et-Vilaine, Morbihan), and the Brittany Region. Headquartered in Cesson-Sévigné, it holds a regional monopoly mandate to build and operate the public fiber optic network across Brittany and to provide shared digital services to Breton public entities. Its president, Loïg Chesnais-Girard, simultaneously serves as President of the Brittany Region.

The organization's core technical asset is the Bretagne Très Haut Débit (BTHD) project, a public FTTH network targeting 100% coverage of Brittany's 1.4 million premises by end 2026. As of early 2025, 890,000 premises were eligible, with 304,000 added in 2024 alone (~800/day, ~25,000/month). The deployment is executed by an Axione–Bouygues Energies & Services consortium under a contract covering Phases 2 and 3, with Phase 2 requiring €800M in investment and total Phases 2+3 exceeding €1B. Network operation is delegated to THD Bretagne (an Orange Concessions subsidiary) under a convention running until 2035. The RUHD (Réseau Ultra Haut Débit) adds a DWDM optical loop serving 11 Breton cities for higher education and research. Construction quality achieves a 2.57% connection failure rate, ranked third-best in France by ARCEP.

Beyond fiber infrastructure, Mégalis operates a bouquet de services numériques providing shared digital tools to member collectives: mon-compte.bzh (unified digital identity with France-Connect integration), mes-services.bzh (public services portal), KorriGo Multiservices (multi-service card with ~600,000 cards in circulation), Oxalis-based urban planning dematerialization (covering 464 communes and 968,000 inhabitants), Breizh Cyber cybersecurity services, Collec-Data automated open data publication, and Focus Marchés procurement transparency. Revenue derives from annual member contributions under a péréquation (solidarity) model, network access fees from commercial ISPs (SFR, Orange, Free, Bouygues, Netensia, Xankom), State and EU subsidies, and digital service subscriptions. The economic model is structured for territorial equity, with less-resourced collectives subsidized by better-resourced ones.
