Europe’s AI and data-centre expansion is creating a new challenge beyond computing capacity: how to deliver the electrical infrastructure needed to power it. 

This issue has come into sharper focus over the past week as industry discussion around Europe’s energy transition has increasingly turned towards grid capacity, connection delays and the ability of existing networks to accommodate major new loads. Data centres are emerging as an important part of that equation. 

For the switchgear market, the implications are significant. 

AI growth is becoming a power infrastructure story 

AI workloads require increasingly power-dense data centres, placing greater demands on the electrical systems connecting facilities to the grid and distributing power across each site. 

Recent research into next-generation AI data centres highlights how increasing AI workloads are creating higher power demand, current transients and thermal stress. It points towards significant changes in power-delivery architecture, including greater use of medium-voltage technologies. 

That puts equipment including medium-voltage switchgear, transformers, protection systems and substations firmly in the conversation. 

Manufacturers are already responding. 

ABB announced a $200 million investment across its European medium-voltage manufacturing network earlier this year. The programme is expanding production capacity for technologies including switchgear and grid automation, with ABB specifically identifying data-centre growth alongside grid modernisation and renewable integration as drivers of demand. 

More demand meets an already constrained grid 

The challenge is that data-centre growth is arriving while European grid operators are already working to increase capacity, reduce connection backlogs and replace ageing infrastructure. 

For switchgear manufacturers and their supply chains, that creates both pressure and opportunity. 

Utilities need equipment to reinforce transmission and distribution networks. Data-centre developers need reliable electrical distribution systems capable of supporting increasingly demanding loads. At the same time, manufacturers are transitioning towards new technologies, including SF₆-free switchgear. 

The result is a market where manufacturing capacity, product availability and delivery times are becoming increasingly important. 

These pressures closely reflect the challenges facing grid operators across Europe, including grid capacity constraints, connection backlogs and manufacturing bottlenecks. For CWIEME Berlin’s T&D community, reducing delivery risk and connecting grid requirements with manufacturing capability are becoming central priorities. 

The opportunity for the electrical manufacturing industry 

The AI infrastructure build-out will not happen through computing hardware alone. 

Behind every new facility sits a substantial electrical value chain, from switchgear and transformers to conductors, insulation, monitoring and grid equipment. 

As Europe works to accommodate new sources of electricity demand, closer collaboration between grid operators, equipment manufacturers and their suppliers will be critical. 

For the switchgear industry, AI may therefore represent more than another end market. It could become one of the forces shaping the next phase of electrical infrastructure investment.
