In September 2024, Enedis Bretagne completed installation of a new approximately 5 km section of HTA submarine cable on the inshore part of the 17 km link from Saint-Gildas-de-Rhuys to the islands of Houat and Hoëdic, with works running in late September (including cable laying from 23 September) to replace the degraded nearshore segment and joint it to the historic cable, enabling the renewed link to be brought into service.
