MaresConnect Interconnector Raises New Capital From Foresight Energy Infrastructure Partners

Updated: Apr 24

London, 11 May 2022

• Funding secured for the project’s development to position MaresConnect as Ireland’s next interconnector • MaresConnect will make a major contribution to achieving Ireland’s 2030 environmental goals Foresight Group Holdings Limited¹, the listed sustainability-led infrastructure and private equity investment manager, has acquired a majority stake in the MaresConnect² interconnector project (“MaresConnect”), through its energy transition fund, Foresight Energy Infrastructure Partners (“FEIP”). Etchea Energy Nominees Limited³ (“Etchea Energy”) will retain the remaining shareholding. The shareholders will work together to complete the development of MaresConnect through to financial close and the start of construction at end 2024.

MaresConnect is a proposed 750MW electricity interconnector linking the power markets of Ireland and Great Britain4. The cable route is approximately 245km in length and will run underground and under the sea between Dublin in Ireland and Bodelwyddan, Denbighshire in Wales. As part of Europe’s 2022 Ten Year Network Development Plan5 (“TYNDP”), MaresConnect is considered one of Europe’s most important energy infrastructure projects that will form part of a system that is secure, sustainable and affordable, and that integrates Ireland’s renewable energy, thereby offering an essential contribution to the European Green Deal.

Simon Ludlam, partner at Etchea Energy and CEO of MaresConnect, said; “We are delighted to welcome Foresight, a well-established and respected infrastructure investor, into the MaresConnect project and look forward to working toward realising the benefits for consumers, energy security and regional jobs and investment in Ireland and Wales. MaresConnect will increase interconnector capacity between Ireland and GB by 50% and make a material contribution to Ireland achieving its 2030 environmental targets as well as providing a cost-efficient export route for Ireland’s growing offshore wind sector.” Richard Thompson, Co-Manager of FEIP and Foresight Partner commented: “This investment represents another very exciting development for both Foresight and FEIP, which is seeking investments into infrastructure that will accelerate the energy transition. Given recent geopolitical events, the economic and social case for increased levels of interconnection has become even more compelling, enhancing European energy security, reducing power prices for consumers and accommodating more renewable energy on the system. We believe this asset will play a pivotal role in the transmission of clean energy between Ireland and Great Britain and are very much looking forward to working with the experienced management team to oversee its development.”

MaresConnect secured a 750MW grid connection at National Grid’s Bodelwyddan substation in 2018 and procurement for the major onshore survey contracts is currently under way. The project will apply for cap & floor regulation in the UK under Ofgem’s third window which is scheduled to open over the summer. The project is expected to have a three-year construction programme leading to operations in 2027.
