Having access to two markets is only valuable if you can manufacture at the volume needed to serve them.

Northern Ireland's manufacturing sector has spent decades training the engineers and technicians who make large-scale production possible.

That experience allows us to take full advantage of our location between the UK and EU markets, manufacturing at the pace and scale major data centre projects demand.

Earlier this week, we welcomed journalists to Cookstown and Ballykelly for an exclusive look behind the scenes of our facilities.

Over two days, Joe Peck, Joe Fay, Jeff Pao, Sander Almekinders, David Sandars, and Kurtis Reid joined our senior leadership team for a tour of our manufacturing capability across water and power infrastructure, including our 300,000 ft² data centre campus.

The visit explored how water and power infrastructure are facing remarkably similar challenges, including ageing assets, tightening environmental standards and the surge in demand driving AI-ready data centre capacity.

Thank you to everyone who joined us for the visit, and for taking the time to explore the technologies and engineering expertise behind two of today's most important infrastructure sectors.

Delivering critical infrastructure without disrupting daily life is no small feat.

We recently completed a major upgrade at Ballinrees Water Treatment Works, outside Coleraine.

Delivered for NI Water, the project has extended the site with a new GAC treatment building and pumping station, boosting treatment capacity and giving the works extra emergency water storage should demand spike.

Throughout construction, every new asset was tested and commissioned before going live, so the works never stopped operating and supply was never interrupted, further strengthening water security for homes, businesses and tourism along the North Coast.

"Astronomical."

That's how our Managing Director, Michael Beagan, described the growth of the sector and the Ballykelly facility he runs in this recent article by BBC Northern Ireland's Economics & Business Editor John Campbell.

Four years ago, our Ballykelly facility started with a team of two. Today, that growth mirrors a much bigger shift taking place across the North West, where manufacturers supplying AI data centres are seeing sustained demand and creating jobs to match.

This BBC Northern Ireland article explores how that consumer shift is changing the region's economy and communities, with local manufacturers leading much of that change.

The FIFA World Cup generates millions of digital interactions every second. ⚽️

Starting with live streaming and broadcast services all the way to scanning a ticket, every digital touchpoint must be powered somehow.

Behind the scenes, data centres process and distribute vast volumes of data in real time, relying on power infrastructure to keep the games live.

Supporting this level of digital demand requires resilient, critical infrastructure that underpins the data centres, enabling global connectivity.

Through the design and manufacture of high-performance power distribution systems, TES Power supports data centre operators as they scale the infrastructure underpinning today's digital economy.
