MaresConnect Interconnector will provide infrastructure to support energy security, put downward pressure on consumer energy prices and help facilitate the transition to a low carbon energy future
bringing benefits to the community
MaresConnect will foster the integration of further, substantial renewable energy sources to support the Irish and UK governments’ 2030 green energy targets and achieve their Net Zero goal. Further interconnection between the two nations will increase security of supply. Interconnection creates downward pressure on wholesale energy prices, leading to savings for energy consumers.
The project is expected to result in approximately €860 million of private capital investment in Ireland and Wales and will create long-term jobs in construction and operations. In addition, the project has the potential to bring further benefits with the inclusion of a high-speed direct fibre optic communications link between Ireland and Great Britain.
Note: The number of homes is based on the annual average household consumption of 4,200kWh (CRU’s decision paper published in March 2017 following its review of typical consumption figures (CER17042)) and an annual total of electricity transmitted via MaresConnect of approximately 2,400,000MWh.
