Echelon Data Centres is establishing Ireland's first Green Energy Park at its DUB20 data centre campus in Arklow, County Wicklow, a move aligned with the Irish Government's Large Energy Users Action Plan (LEAP) for co-locating large energy users with renewable generation.

The Arklow Green Energy Park comprises the DUB20 data centre, a new shared 220kV electricity substation connecting the campus to SSE's 800 MW Arklow Bank Wind Park 2 offshore wind project, on-site solar generation, and on-site battery storage, plus grid-supporting energy infrastructure. Two on-site energy centres are planned, including one capable of exporting power to the national grid, and battery systems that use hydrotreated vegetable oil to cut emissions.

The LEAP initiative sets out a plan-led pathway for Green Energy Parks, including flexible or hybrid grid connections, private wire connections, and routes for corporate power purchase agreements with offshore wind generation. The Arklow park is designed in direct alignment with that framework.

The DUB20 campus sits at the former Irish Fertilisers Industries site at the Avoca River Business Park and forms part of Echelon's 4.2 billion euro investment in the DUB20 and DUB30 facilities in Wicklow. DUB20 is due to be completed by 2028.

An independent KPMG economic impact assessment found the DUB20 and DUB30 campuses could generate up to 7.5 billion euro in economic output during construction and 801 million euro annually once operational, with every euro invested yielding an estimated 1.60 euro in wider economic activity.

"Creating Ireland's first Green Energy Park at DUB20 demonstrates how large-scale digital infrastructure can be developed responsibly and in lockstep with national climate and energy policy," said Echelon chief strategy officer Graeme McWilliams. "By co-locating data centre capacity with offshore wind, onsite solar and grid-supporting infrastructure, we are delivering the exact model envisioned under the Government's LEAP framework."
