Siemens acts as Mutual Energy’s long‑term maintenance provider for the Moyle Interconnector, supporting ongoing operation of the two HVDC converter stations at Ballycronan More and Auchencrosh. In this role Siemens provides maintenance and technical support services for the converter equipment and associated systems. As of 2025, Siemens also assisted Mutual Energy and contractor Dowds Group in integrating a new on‑site solar PV array at the Ballycronan More converter site, ensuring that the additional low‑carbon generation interfaced reliably with the existing HVDC infrastructure.
