A new trade association has been formed to represent homegrown Irish companies that operate in the data centre supply chain. The Irish Data Centre Supplier Alliance, or IDCSA, will represent companies across planning, design, construction, mechanical & electrical engineering, energy management, automation and technical services that have benefited from data centre investment in Ireland.
The IDCSA was officially announced on Monday 23rd February 2026 at Grange Castle Business Park, Co Dublin. In attendance were three founding members of the association: DECI Ltd, Dornan Engineering, and STS Group. In addition, former Director General of the Construction Industry Federation (CIF) and a former Minister of State in the Department of Finance, Tom Parlon was announced as the first chair of the IDCSA.
“The growth of the data centre industry over the past 15 years has been one of the foundations of Ireland’s economic recovery since the financial crash. The sector has contributed over €20 billion through direct and indirect investment during that time, directly employing 1,800 people whilst supporting thousands more jobs across the Irish supply chain,” Tom Parlon said.
“There is a significant amount of negativity surrounding the data centre industry at the moment. While power constraints are a reality we must address, we shouldn’t lose sight of the fact that Ireland is a global nerve centre for the digital age. We are here to focus on the positives of job creation, technological advancement, and the massive export of Irish expertise,” Colm Phelan, Director of DECI Ltd.
“Dornan is proud to support the establishment of the IDCSA as a dedicated advocate for Ireland’s data centre supply chain. As Irish engineering capability continues to scale globally, the IDCSA will play a critical role in aligning the sector on standards, regulatory engagement and responsible growth,” Joe Conway, Business Development Manager at Dornan Engineering, said.
“STS Group is delighted to join the newly established IDCSA. We believe this much needed trade association will play key role in reinforcing the positive influence the data centre sector has had for firms such as STS Group. As an international company, we will take the learnings and success stories experienced in other jurisdictions that can form part of the solution in re-positioning Ireland as the location of choice for new data centre investment in the future,” David Quinn, Business Development Manager with STS Group, said.
