The European Commission has approved two Connecting Europe Facility (CEF) grants to support the construction of the Celtic Interconnector - a proposed 700 MW HVDC undersea power cable project connecting Knockraha in the Cork region of Ireland to La Martyre in Finistère (France) - and studies for the development of the Harmony Link Interconnector between Lithuania and Poland, that will help synchronise the Baltic countries with the European power grids.
In October 2019, the European Commission approved a €530m funding for the €1bn Celtic interconnector project, which has been declared a Project of Common Interest (PCI). Construction works will start in 2023 and the project should be commissioned in 2026. It is expected to deliver enough electricity to supply about 450,000 households, to improve electricity supply security and to promote renewable power generation.
The Harmony Link electricity interconnector will receive a €10m grant and will be a key in the integration of Baltic electricity markets. In June 2018, Baltic states, Poland and the European Commission signed a Political Roadmap to achieve the synchronisation by the target date of 2025.
