Île de Bréhat

Ile de Bréhat has been connected to the mainland French electrical grid via submarine cable for several decades. The exact date of original electrification / first cable commissioning is not available in the public sources consulted (2026-04-14 research). The Iles du Ponant press dossier ("Les îles à la pointe de la décarbonisation") confirms the island is part of the standard Enedis distribution concession, implying the cable predates any modern public announcement of individual island links. Most French Atlantic small-island Enedis submarine cables date from the late 1960s to 1970s when the national electrification programme reached remote islands; 1970 is used here as an approximate placeholder to reflect "operational since at least the 1970s" pending authoritative confirmation from Enedis Côtes-d'Armor or the Association des Amis des Câbles Sous-Marins (cablesm.fr). Event date precision is explicitly marked 'approximate'; actual date should be backfilled when an authoritative source is located.
