Global data centre infrastructure company Vertiv has lodged plans for a major expansion at its Letterkenny plant.
The planning application seeks permission for an additional 8,485 square metres (91,000 sq ft) of new production facility space on a 3.5 hectare (8.6 acre) site adjacent to its current facility at Lisnennan.
The proposed development will also include the provision of additional car parking, provision of bicycle parking and new footpaths and public lighting.
Vertiv’s Irish operation more than doubled its pre-tax profits last year as demand surges for data-centre equipment.
Revenues at Vertiv Ireland Limited rose from €131.2 million to €182.5 million in 2025, while pre-tax profits increased from €43.6 million to €111.6 million, the Irish Times reported.
The company has major operations in Letterkenny and Burnfoot, as well as Campsie in Derry.
Up to 300 skilled jobs are expected to be created with the latest expansion.
The company has added more than 500 staff across its Irish operations since the start of the year.

The company manufactures power, cooling and IT infrastructure used by data centres, with the expansion driven by growing global demand linked to AI.
Vertiv’s parent company reported global sales of $10.2 billion in 2025, up almost 28% on the previous year. Its order backlog more than doubled to $15 billion as data-centre customers placed orders ahead of the company’s ability to fulfil them.
Vertiv’s global and local expansion plans are designed to increase manufacturing capacity as demand accelerates from AI, colocation and hyperscale data-centre projects.
