Data Centres: Boom and BacklashBackground
Avaio Digital invests in and develops digital-infrastructure projects, including data centres. Its role combines financial backing with project development rather than planning regulation, electricity supply or grid operation.
Data-centre developers depend on planning permission, power access and electricity arrangements before projects can proceed. On 17 September, the refusal of the Mayo scheme backed by Avaio Digital illustrated those constraints.
The company’s work therefore sits where investment decisions meet site delivery. The Mayo ruling concerned a proposed project, not Avaio Digital’s role as a planning authority or power provider.
Mayo refusal stalls Avaio project
On 17 September, Ireland’s planning appeals board refused the €1.5bn Killala data-centre proposal backed by Avaio Digital. The decision overturned Mayo County Council’s 2025 approval, leaving the scheme without planning permission.
For Avaio Digital, the ruling leaves a proposed investment exposed to planning and infrastructure conditions. The board found that the scheme lacked a confirmed grid connection and renewable-power contract, both required before it would grant approval.
