Project Overview
The Greenlink interconnector, a 504 MW HVDC link, has initiated its commercial operations as the first privately financed interconnector in Europe. It operates under the Cap & Floor regulatory regimes established in both the UK and Ireland. This strategic link connects EirGrid’s Great Island substation in County Wexford, Ireland, with the National Grid’s Pembroke substation in Pembrokeshire, Wales, enabling seamless bidirectional power flow tailored to meet supply and demand needs.
Commencing construction in January 2022, the project acquired essential core consents in 2021. The engineering, procurement, and construction (EPC) contract is jointly held by a consortium that includes Siemens Energy and Sumitomo Electric, both renowned for their expertise in high-stakes infrastructure projects. This partnership is crucial in ensuring that the interconnector is constructed to the highest standards of engineering and reliability, vital for integrating renewable energy sources across borders.
Spanning approximately 190 km with both subsea and underground elements, this infrastructure project enhances the electricity grid’s resilience and lays the groundwork for future energy transitions, promoting greater energy interdependence between the two nations. As demand for renewable energy continues to rise, interconnectors like Greenlink play a crucial role in facilitating the trade of green electricity, ultimately leading to reduced carbon footprints for both markets.
This project reflects a pioneering approach to energy connectivity, propelling nations to cooperate in addressing climate challenges and energy security concerns. The operational capabilities of the Greenlink interconnector will significantly influence energy strategy and market stability across the region, setting a benchmark for potential future projects aimed at enhancing cross-border energy collaboration. The project is projected to reach full completion in the early months of 2025, heralding a new era of energy exchange between Ireland and Great Britain characterized by lower costs and greater accessibility for consumers.
Numerous studies and surveys have preceded the construction phase, which reflects comprehensive planning efforts to ensure the safety and efficacy of the link. These efforts highlight the meticulous groundwork necessary for such an ambitious initiative. The Greenlink interconnector stands as a crucial step not just for energy transit but for a sustained commitment toward a greener future.

Construction and Timeline
The Greenlink interconnector project has undergone several key phases, each crucial for its successful completion. The project’s inception required thorough groundwork, beginning with the acquisition of core consents in 2021. This critical step involved addressing regulatory frameworks and ensuring compliance with environmental and infrastructural guidelines, setting the foundation for subsequent construction phases.
Onshore construction work commenced in January 2022, with preliminary works initiated in two key regions: Pembrokeshire in Wales and County Wexford in Ireland. This phase involved preparing the sites for the necessary infrastructure to support the 190-kilometer long and 500 MW HVDC submarine power cable connecting the electricity grids of both nations. The cable’s route includes subsea and underground components, facilitating enhanced energy trading capabilities and improved grid stability between Ireland and Great Britain.
The construction timeline spans over three years, with commercial operations projected to commence on January 29, 2025. This timeline is aligned with the strategic goals of increasing interconnections in Europe’s energy landscape, optimizing resource allocation, and bolstering energy security for both regions. The process involves ongoing collaboration with local communities, regulatory bodies, and environmental stakeholders to mitigate impacts and maximize communal benefits.
The EPC contract for the Greenlink project is entrusted to a consortium comprising Siemens Energy and Sumitomo Electric, ensuring adherence to high standards of quality and efficiency. This partnership encompasses extensive experience in HVDC technology and large-scale infrastructure projects, critical for the successful delivery of the interconnector. Their commitment extends beyond delivering infrastructure; it also supports the broader European initiative for greener and more integrated energy systems. As the project progresses toward its completion, it exemplifies innovation and collaboration in energy connectivity.
In summary, the Greenlink interconnector represents a significant advancement in connecting Ireland and Great Britain. With its phased construction approach and an enforced completion timeline, the project promises to reshape energy distribution in the region, enhancing reliability and fostering economic growth through improved connectivity.
Impact and Benefits
The Greenlink interconnector is poised to profoundly impact the energy infrastructure of both Ireland and Great Britain. By enhancing grid stability and reliability, the interconnector reduces dependence on single suppliers and supports the integration of renewable energy sources. This project not only facilitates a balanced supply and demand of electricity but also contributes to job creation and economic growth.
Integral to this initiative is the construction of a 190 km long, 500 MW HVDC submarine cable linking County Wexford, Ireland, with Pembrokeshire, Wales. By enabling bi-directional electricity flows, it creates a more resilient energy network that can adapt to changing demands and renewable energy generation variances. Consequently, it can effectively address potential energy shortages or surpluses in either region, fostering energy security and reducing price volatility in electricity markets [Greenlink].
The interconnector’s economic implications extend beyond the immediate energy market. Statistically, the project is expected to create a significant number of jobs throughout its construction and operational phases, contributing to local economies in both counties. This includes not only direct employment in construction and engineering but also induced jobs across various sectors, such as service and supply chains resulting from increased economic activity [NS Energy].
Moreover, the interconnector aligns with global efforts to combat climate change by facilitating renewable energy transmission. With its capacity to connect wind farms in Ireland with the UK grid, it directly supports the higher integration of clean energy sources and minimizes reliance on fossil fuels. This contributes to a reduction in carbon emissions and supports overall sustainability objectives [Société Générale].
In summary, the Greenlink interconnector enhances the reliability of electricity supply between Ireland and Great Britain while representing a significant step toward a greener and more integrated energy future, ultimately benefiting consumers and the environment alike.
Future Prospects
Looking ahead, the Greenlink interconnector opens up possibilities for expansions and upgrades. Future enhancements could include increased capacity and improved technological integration.
