Ireland’s renewable energy sector is taking significant strides forward, with solar power playing an increasingly vital role. A prime example of this momentum is the success of solar projects within the country’s Renewable Electricity Support Scheme (RESS). The recent RESS 5 auction highlighted this trend by awarding contracts to three key solar energy projects, totalling 28.7 MW. These projects, owned by Elios Energy and developed by Clonakilty Energy, are slated to become operational by the end of 2025, marking another win for Ireland’s green transition.
Elios Energy and the Ireland solar energy auction Partnership
The Renewable Electricity Support Scheme (RESS) is the cornerstone of Ireland’s strategy for a renewable energy future. Through a competitive auction process, the scheme provides financial certainty for developers, helping Ireland meet its ambitious climate and energy targets while ensuring value for money. For homeowners and tenants in Germany, this model is familiar, echoing principles of the Erneuerbare-Energien-Gesetz (EEG) which has been pivotal in scaling renewables there. The success of projects in the RESS 5 auction demonstrates the scheme’s effectiveness in driving investment.
The three solar energy projects—Mountmellick Solar (4 MW), Graiguecullen Solar (11.4 MW), and Monasterevin Solar (13.3 MW)—are set to be developed by Elios Energy in partnership with Clonakilty Energy. Located across County Laois and County Kildare, their combined 28.7 MW capacity will be a substantial addition to Ireland’s renewable energy mix. Understanding the technology involved gives a sense of the scale; for those interested, the basics of solar panel manufacturing provide a great introduction to how these power-generating assets are created.
Elios Energy has committed to a timely delivery, having already secured planning permission and being in the final stages of arranging grid connections. Their partnership with Clonakilty Energy is particularly noteworthy. Clonakilty’s specialisation in community-focused projects reflects a growing trend across Europe, including Germany’s Bürgerenergie (citizen energy) movement, which empowers local communities to participate in and benefit from the energy transition.
Elios Energy’s Role in the Ireland solar energy auction Market
Elios Energy stands out as a leading independent power producer (IPP) in the burgeoning Irish solar market. With a strong track record in the development, construction, and operation of solar farms, the company has become a major force since its establishment in 2019 as a joint venture between Terra Solar and Island Renewable Energy.
With projects spread across Ireland, particularly in counties like Cork, Kerry, and Limerick, Elios Energy is pivotal in helping the nation achieve its renewable energy goals. The company is on a clear path to becoming Ireland’s largest solar IPP, managing a development portfolio that exceeds 1 GW. Bringing such a vast pipeline of projects to life involves a complex global supply chain, starting with sourcing essential solar panel raw materials like silicon and silver. Elios Energy’s commitment is to deliver clean, reliable, and renewable energy to the Irish grid, strengthening the country’s energy security.
RESS 5 Auction and the Renewable Energy Market in Ireland solar energy auction
The RESS 5 auction is a critical component of Ireland’s long-term energy strategy. Administered by the grid operator EirGrid and the Department of the Environment, Climate and Communications (DECC), the scheme provides financial support that makes renewable electricity more affordable for consumers. This state-backed support has been instrumental in attracting significant investment into both solar and onshore wind projects.
This auction is part of a much broader national effort. The Irish government has set a bold target of generating 80% of its electricity from renewable sources by 2030. While solar is rapidly expanding, wind energy remains a powerhouse, with capacity expected to reach 5.25 GW by 2025. This dual-pronged approach diversifies the energy mix and enhances grid stability. For German observers, Ireland’s progress is relevant; as part of an interconnected European grid, a greener Irish energy supply contributes to the overall decarbonisation of the continent’s power system.
The results of the RESS 5 auction underscore the increasing competitiveness and appeal of solar energy in Ireland. The awarded projects not only contribute directly to climate goals but also stimulate further investment in the sector. The entire lifecycle of these projects, from the intricate solar panel manufacturing process to their eventual operation, creates jobs and fosters a domestic green economy.
As Ireland continues to build out its renewable capacity, the lessons learned can inform energy policy across Europe. For anyone interested in the practicalities of bringing such large-scale solar initiatives to fruition, from the technology to the economics, a deeper dive is essential.
