MEP Billy Kelleher Visits ACI Worldwide’s Limerick Data Centre, Marking A Decade Powering Europe’s Digital Payments

WHY THIS MATTERS: A ten-year milestone for dedicated physical infrastructure in Europe signals a pivotal market response to the twin demands of regulatory compliance and high-availability processing. As the continent pushes aggressively toward greater adoption of real-time payments and grapples with stringent EU data privacy laws, providers must guarantee data residency and rock-solid operational uptime. This long-term investment by ACI in its European hub reflects the critical importance of regionalized, high-security private cloud environments. For financial institutions and large merchants, relying on such a localized foundation is key to ensuring continuous, mission-critical services while confidently meeting requirements for data sovereignty and regulatory oversight across EMEA. This development underscores that infrastructure security remains a non-negotiable foundation for scaling digital commerce.

ACI Worldwide hosted MEP Billy Kelleher at its Limerick data centre at the National Technology Park. The visit comes as ACI marks ten years since opening its Limerick data centre, reflecting the company’s long-term investment in Ireland.

MEP Billy Kelleher met with ACI leadership and tour the data centre to learn more about the infrastructure supporting digital payments across Europe. The state-of-the-art European hub supports ACI’s customers across Europe, the Middle East and Africa (EMEA). Its purpose is to deliver secure and reliable infrastructure for real-time digital payments. A key function of the site is to extend ACI’s private cloud, allowing customers to access ACI’s payment software solutions without running their own on-site systems. This enables businesses to scale securely while benefiting from reliable, high-performance payment capabilities and guaranteed service levels. 

Through this, ACI Worldwide’s European headquarters provides the environment required to run real-time electronic banking, card processing merchant acquiring, and other mission‑critical payment services, supporting some of Europe’s largest merchants, intermediaries, and financial institutions including Ireland’s two biggest banks. Built to high security standards, the data centre includes full system backup across power, network and operations to ensure continuous uptime. It is also designed to meet European data privacy requirements, with data handled within the region to help customers comply with EU regulatory expectations.  ACI has had a presence in Limerick for more than a decade and continues to invest in the region. The European hub forms part of Ireland’s role as a global data centre hub and contributes to the country’s growing cluster of international data operations.

“Payments are the backbone of Europe’s digital economy, and from Limerick we power the secure, real‑time services that keep commerce moving. Our European data centre has grown into a dynamic hub for banks and payment providers across the region, ensuring millions of everyday transactions happen safely and seamlessly,” commented Martina Power, global head of professional services, ACI Worldwide. “The operation reflects the incredible expertise of our team in Limerick and ACI’s long‑term commitment to driving innovation in digital payments across Europe.” 

“Ireland continues to play an important role as a hub for technology investment, supporting jobs and innovation across the region,” said MEP Billy Kelleher. “Operations such as ACI Worldwide’s Limerick data centre demonstrate how long‑term investment, combined with skilled regional talent, contributes to the development of secure and reliable digital infrastructure. I welcome ACI Worldwide’s ongoing commitment to Ireland and the positive contribution this site makes to the local and national economy.”

ACI representatives attending the visit include Martina Power, Global Head of Client Delivery and Site Leader; Jimmy Hennessy, Global Head of AI & Data Science; Shane Blake, Regional Director, Human Resources; Peter Gorley, Regional Sales Director, UK & Ireland; and Mike Holden, Head of Data Centre Operations.

FF NEWS TAKE: The celebration of a decade of investment in a European processing hub confirms the strategic importance of physical data centers in the digital payments landscape. This move does not change the industry overnight, but it reinforces ACI’s foundation for future growth in mission-critical services. The next phase to watch is how ACI leverages this highly compliant, high-performance platform to deploy AI and machine learning tools, particularly in relation to fraud prevention and regulatory reporting, to gain a competitive edge in core payments processing as cross-border payment complexity increases.
