Regulator Ofgem Approves New Electricity Connections Between Great Britain and Ireland

Great Britain’s energy regulator, Ofgem, has granted approval for two new electricity interconnections linking Britain with the island of Ireland. One of these initiatives will establish a link between Scotland and Northern Ireland, while the other will connect Wales and the Republic of Ireland. Initially, Ofgem had turned down these projects due to worries regarding potential expenses for consumers in Great Britain. Nevertheless, the regulator’s ultimate ruling stated that the benefits of enhancing supply security superseded these cost concerns. Akshay Kaul, who serves as the director general for infrastructure at Ofgem, commented: “We’ve carefully assessed all the proposed projects and only approved those ones which deliver for consumers in terms of value, viability and energy security.” In total, Ofgem has sanctioned five interconnection projects, which it estimates will result in an increase of £2 to £5 annually on individual electricity bills for consumers in Great Britain during the period from 2030 to 2055. This approval signifies that the projects are eligible for Ofgem’s ‘cap and floor’ regulatory framework, which guarantees the financial returns they will generate. This framework ensures developers receive a minimum return (floor) while also setting a limit on potential profits (cap) over a 25-year duration. Transmission Investment is developing the connection between Scotland and Northern Ireland, identified as LirlC. The company stated that this project is designed to supply up to 700 MW of capacity, linking the Irish Single Electricity Market with the Great Britain wholesale electricity market. While both projects still need to overcome additional regulatory and planning obstacles, Ofgem’s endorsement significantly increases their probability of proceeding. A 500 MW interconnector already exists between Scotland and Northern Ireland, managed by Mutual Energy since 2001. Additionally, a second 500 MW connection, named Greenlink, linking the Republic of Ireland and Wales, is anticipated to become operational soon. Keith Morrison, the Project Director for LirIC, commented: “Transmission Investment are pleased with Ofgem’s announcement today and its recognition of the benefits that LirIC will bring to consumers in Great Britain and Northern Ireland.“In the coming months we anticipate more important milestones including the completion of further regulatory licencing requirements.””
